[0002] As a core tool in household cleaning supplies, the technological development of cleaning brushes revolves around aspects such as cleaning efficiency, hygiene, and user experience.

[0003] Currently, before using a traditional cleaning brush to clean stains, users usually need to manually hold the container (such as a cleaning bottle) to hold the cleaning solution and pour or spray the solution onto the stained area, and then manually switch to the cleaning brush to remove the stains through physical friction.

[0004] However, when users need to clean multiple stains, they need to repeat the above steps of first manually holding the container to pour or spray the cleaning solution, and then switching to the cleaning brush for cleaning. The cleaning operation is inconvenient, the user experience is poor, and the cleaning efficiency is low. Utility Model Content

[0005] This utility model provides a cleaning device and a cleaning brush to solve the problems of inconvenient cleaning operation, poor user experience, and low cleaning efficiency in related technologies.

[0006] According to one aspect, the present invention provides a cleaning device, including a cleaning brush and a brush base. The brush base is provided with a cleaning liquid storage chamber, a cleaning brush storage chamber and a liquid extraction channel. The liquid extraction channel is connected to the cleaning liquid storage chamber, and the cleaning brush can extract the cleaning liquid from the cleaning liquid storage chamber into the cleaning brush through the liquid extraction channel.

[0007] The cleaning device provided by this utility model includes a cleaning brush and a brush holder. The brush holder is used to accommodate and place the cleaning brush. Specifically, the brush holder is provided with a cleaning liquid storage chamber, a cleaning brush storage chamber, and a liquid dispensing channel. The cleaning brush can be placed in the cleaning brush storage chamber, and the cleaning brush can also be connected to the cleaning liquid storage chamber through the liquid dispensing channel so that the cleaning liquid stored in the cleaning liquid storage chamber can be taken out into the cleaning brush through the liquid dispensing channel. When using the cleaning brush, the user can directly use the cleaning liquid in the cleaning brush and use the cleaning brush to clean the stains. The user does not need to frequently switch between holding the cleaning liquid container and the cleaning brush during the cleaning process, which effectively improves the user experience and cleaning efficiency.

[0008] According to the present invention, a cleaning device is provided with a suction tube on the cleaning brush. The suction tube extends into the liquid extraction channel to draw the cleaning liquid in the cleaning liquid storage chamber into the cleaning brush.

[0009] This embodiment provides a specific implementation of a cleaning brush. The cleaning brush is equipped with a suction tube. By inserting the suction tube into the liquid dispensing channel to communicate with the cleaning liquid storage chamber, the cleaning brush can draw cleaning liquid from the storage chamber into the cleaning brush. The suction tube directly immerses the brush in the cleaning liquid, facilitating effective liquid intake, reducing air intake, increasing the amount of cleaning liquid drawn into the brush, and making it easier for the user to use.

[0010] According to the present invention, a cleaning device is provided, wherein the liquid collection channel is located on the bottom surface of the cleaning brush storage cavity, the cleaning brush includes a brush rod and a brush head, and the suction tube is located on the brush head at a position opposite to the liquid collection channel.

[0011] This embodiment provides a specific implementation of the liquid dispensing channel and the suction tube position on the cleaning device. Specifically, the liquid dispensing channel is located on the bottom surface of the cleaning brush storage cavity. The cleaning brush includes a brush handle and a brush head. The suction tube is located on the brush head opposite the liquid dispensing channel. When the user holds the brush handle and inserts the brush head into the cleaning brush storage cavity, the suction tube on the brush head extends into the liquid dispensing channel on the bottom surface of the cleaning brush storage cavity to communicate with the cleaning liquid storage cavity and effectively draw up the cleaning liquid. The placement of the suction tube avoids it occupying the lateral space on the brush head, allowing for more cleaning bristles on the brush head, thus improving cleaning effect and efficiency.

[0012] According to the present invention, a cleaning device is provided, wherein the brush head includes bristles and a bristle carrier, the bristle carrier is provided with an insert groove with the opening facing downward, the liquid dispensing channel is inserted into the insert groove when the brush head is placed into the cleaning brush storage cavity, and the suction tube is disposed in the insert groove.

[0013] This embodiment provides a specific implementation of the brush head. The brush head includes bristles and a bristle carrier. The bristles are disposed on the bristle carrier, which has a downward-facing insertion groove. When the user holds the brush handle and places the brush head into the cleaning brush storage cavity, the liquid dispensing channel located at the bottom of the cleaning brush storage cavity is inserted into the insertion groove, and a suction tube is disposed in the insertion groove, allowing the tube to extend into the liquid dispensing channel to dispense liquid. Furthermore, since the liquid dispensing channel extends upward and is embedded in the insertion groove, more cleaning liquid can be stored.

[0014] According to the present invention, in a cleaning device, the lower end of the straw is higher than or flush with the opening of the embedded groove.

[0015] This embodiment provides a specific implementation of the straw. Specifically, the lower end of the straw is higher than or flush with the opening of the embedding groove, to avoid the straw being too long and affecting the user's normal use of the cleaning brush.

[0016] According to the present invention, a cleaning device is provided in the brush holder, wherein the suction tube extends into the liquid collection channel and can be connected to the top of the transfer tube to draw cleaning liquid through the transfer tube.

[0017] This embodiment provides a specific implementation of the brush holder. The brush holder includes an adapter tube. After the suction tube on the brush head extends into the liquid dispensing channel, it connects with the top of the adapter tube to draw in cleaning fluid. This avoids the problem of the suction tube being too short, making it difficult to effectively contact the cleaning fluid and thus effectively draw in the cleaning fluid. The adapter tube in the brush holder effectively connects to and draws in the cleaning fluid storage chamber. Even with a shorter suction tube to avoid affecting the brushing effect, it ensures that the suction tube can effectively draw in the cleaning fluid.

[0018] According to the cleaning device provided by this utility model, the brush holder is further provided with a fixing structure, which is used to fix the bottom end of the adapter tube at the lowest position of the cleaning liquid.

[0019] This embodiment provides a specific implementation of setting up an adapter tube. The brush holder also includes a fixing structure to fix the bottom end of the adapter tube at the lowest point of the cleaning liquid, preventing the bottom end of the adapter tube from not sinking and thus making it difficult to fully absorb the cleaning liquid through the adapter tube. This application uses a fixing structure to fix the bottom end of the adapter tube, facilitating the suction tube on the brush head to fully absorb the cleaning liquid through the adapter tube.

[0020] According to the present invention, a cleaning device is provided, wherein the fixing structure includes a support member and a fixing member. The support member is fixed at the lowest position and supports the bottom end of the adapter tube so that a liquid inlet channel for cleaning liquid to enter the adapter tube is left below the bottom end of the adapter tube. The fixing member is provided on the support member and inserted into the bottom end of the adapter tube.

[0021] This embodiment provides a specific implementation of the fixing structure. The fixing structure includes a support and a fixing member. The support is fixed to the lowest point of the cleaning fluid (e.g., fixed to the bottom of the cleaning fluid storage chamber) and supports the bottom end of the adapter tube, so that an inlet channel for the cleaning fluid to enter the adapter tube is left below the bottom end of the adapter tube. The fixing member is disposed on the support and inserted into the bottom end of the adapter tube to fix the bottom end of the adapter tube relatively around the support, preventing the adapter tube from moving with the shaking of the cleaning fluid in the cleaning fluid storage chamber. This allows the bottom end of the adapter tube to be effectively aligned with the lowest point of the cleaning fluid, facilitating sufficient fluid intake.

[0022] According to the present invention, a cleaning device is provided, wherein the support member is a first cross-shaped structure, and the same side of the four plates of the first cross-shaped structure is fixed to the lowest position. The fixing member is connected to the other side of the four plates of the first cross-shaped structure, and the liquid inlet channel is between any two adjacent plates among the four plates.

[0023] and / or

[0024] The fixing component is a second cross-shaped structure, and the channels between two adjacent plates of the four plates of the second cross-shaped structure are all connected to the liquid inlet channel.

[0025] This embodiment provides a specific implementation of the support and fixing components. Specifically, the support can be a first cross-shaped structure, with each of the four plates fixed to the lowest point on the same side. The other side of the four plates can support the bottom of the adapter tube, and each pair of adjacent plates forms a liquid inlet channel, allowing cleaning fluid to be drawn from below the bottom of the adapter tube. The fixing component can be connected to the other side of the four plates of the first cross-shaped structure to relatively fix the bottom of the adapter tube. Alternatively, the fixing component can be a second cross-shaped structure, where the channels between adjacent plates of the four plates are connected to the liquid inlet channels, allowing cleaning fluid to be drawn from below the bottom of the adapter tube. The support and fixing components in this application are simple in structure, use less material, and are low in cost, yet they effectively support and fix the bottom of the adapter tube, and provide channels for drawing cleaning fluid, facilitating effective suction of cleaning fluid by the cleaning brush.

[0026] According to the present invention, a cleaning device is provided in which an anti-overflow channel is provided at the top of the liquid dispensing channel. The anti-overflow channel is used to prevent the cleaning liquid from overflowing when the suction tube is inserted into the liquid dispensing channel and the liquid level of the cleaning liquid rises.

[0027] This embodiment provides a specific implementation of the liquid dispensing channel. Specifically, an overflow prevention channel is provided at the top of the liquid dispensing channel. When the straw is inserted into the cleaning liquid in the liquid dispensing channel, the liquid level of the cleaning liquid will rise because the straw occupies part of the space. By designing this overflow prevention channel, this application can effectively prevent the cleaning liquid from overflowing outside the liquid dispensing channel.

[0028] According to the cleaning device provided by this utility model, the length of the overflow prevention channel is in the range of 2mm to 6mm.

[0029] This embodiment provides a specific implementation method for setting the length of the anti-overflow channel. Specifically, based on the dimensions of the straw and the liquid dispensing channel, the height to which the cleaning liquid may be raised when the straw is inserted into the liquid dispensing channel can be calculated. Based on this, the length of the anti-overflow channel in this application is set in the range of 2mm to 6mm, which can effectively prevent the cleaning liquid from overflowing outside the liquid dispensing channel without affecting the normal use of the cleaning device.

[0030] According to the present invention, a cleaning device is provided in which the liquid extraction channel is disposed in the cleaning brush storage cavity, the lower end of the liquid extraction channel is connected to the cleaning liquid storage cavity, and the upper end of the liquid extraction channel extends to the top of the cleaning liquid storage cavity.

[0031] This embodiment provides a specific implementation of the liquid dispensing channel's location. Specifically, the liquid dispensing channel is located within the cleaning brush storage chamber. The lower end of the channel communicates with the cleaning fluid storage chamber, while the upper end extends to the top of the chamber. This arrangement allows the liquid dispensing channel to connect the cleaning fluid storage chamber and the cleaning brush while minimizing the need for additional space outside the brush holder, saving space in the entire cleaning device and improving ease of use. Furthermore, the upper end of the channel extending to the top of the cleaning fluid storage chamber allows for the storage of more cleaning fluid without the need for a valve at the upper end of the channel. For example, the liquid level can be brought close to the top of the storage chamber, as long as it is below the upper end of the dispensing channel, preventing overflow.

[0032] According to the present invention, a cleaning device is provided, wherein the brush holder includes a shell and an inner liner, the cleaning liquid storage cavity is disposed between the shell and the inner liner, and the cleaning brush storage cavity is disposed in the inner liner.

[0033] This embodiment provides another specific implementation of the brush holder. The brush holder includes a housing and an inner liner. A cleaning fluid storage chamber is located between the housing and the inner liner, and a cleaning brush storage chamber is located within the inner liner. Compared to additionally setting two separate parts for storing the cleaning fluid and the cleaning brush, this application effectively utilizes the specific structure of the brush holder to separate the cleaning fluid storage chamber and the cleaning brush storage chamber, effectively saving space in the entire cleaning device and making it convenient to use.

[0034] According to the present invention, a cleaning device is provided in which the inner liner is detachably connected to the outer shell. When the inner liner is installed in the outer shell, the inner liner presses down on the cleaning liquid, causing the liquid level of the cleaning liquid to rise. The liquid extraction channel is located inside the inner liner. The lower end of the liquid extraction channel communicates with the cleaning liquid storage cavity, and the upper end of the liquid extraction channel extends toward the opening of the inner liner to buffer the rising liquid level of the cleaning liquid and prevent the cleaning liquid from overflowing from the upper end of the liquid extraction channel.

[0035] This embodiment provides a specific implementation of the brush holder installation method. Specifically, the inner liner and outer shell are detachably connected, allowing the user to directly add cleaning fluid to the outer shell and insert the inner liner. When the inner liner is inserted into the outer shell, it presses down on the cleaning fluid stored in the outer shell, causing the fluid level to rise. The fluid dispensing channel is located inside the inner liner, with its lower end communicating with the cleaning fluid storage cavity and its upper end extending towards the opening of the inner liner. When the cleaning fluid level rises, the extended dispensing channel buffers the rising fluid level, preventing overflow from the upper end of the channel. This effectively prevents cleaning fluid overflow during inner liner installation, improving the user experience.

[0036] According to the present invention, a cleaning device is provided in which the inner liner and the outer shell are connected by a rotary connection structure.

[0037] This embodiment provides a specific implementation method for the connection between the inner liner and the outer shell. Specifically, the inner liner and the outer shell are connected by a rotary connection structure. This rotary connection allows the inner liner to be more securely installed on the outer shell, preventing the inner liner from being pulled out when the user removes the cleaning brush from the brush holder. In addition, compared to directly connecting the inner liner and the outer shell vertically, the rotary connection can, to some extent, prevent the cleaning fluid from being squeezed out due to excessive force applied by the user during installation, further improving the user experience.

[0038] According to the present invention, a cleaning device is provided, wherein the rotary connection structure includes a first sliding groove disposed on the inner surface of the outer shell and a locking block disposed on the outer surface of the inner liner. The first sliding groove includes a first locking groove and a guide groove. The inner liner and the outer shell can rotate relative to each other so that the locking block slides from the guide groove into the first locking groove for locking.

[0039] This embodiment provides a specific implementation of the rotary connection structure. The specific rotary connection structure includes a first sliding groove on the inner surface of the outer shell and a locking block on the outer surface of the inner liner. The first sliding groove includes a first locking slot and a guide groove. When the inner liner and the outer shell rotate relative to each other, the locking block can slide from the guide groove into the first locking slot for engagement. The guide groove helps the user to more easily achieve engagement between the locking block and the first locking slot through rotation. The structure is simple and convenient to use.

[0040] According to the present invention, a cleaning device is provided on the outer shell, which is used to indicate the highest liquid level when the inner liner is not installed in the outer shell, so as to avoid the liquid level of the cleaning liquid being higher than the preset liquid level after the inner liner is installed in the outer shell.

[0041] This embodiment provides a specific implementation of the outer shell. Since inserting the inner liner into the outer shell will compress the cleaning fluid inside, causing the fluid level to rise, to prevent the cleaning fluid from overflowing, this application provides a fluid level indicator on the outer shell. This indicator shows the maximum fluid level when the inner liner is not inserted, preventing the fluid level from exceeding a preset level after the inner liner is inserted, thus avoiding overflow. Users can pour in cleaning fluid below the indicated level to ensure no overflow.

[0042] According to the cleaning device provided by this utility model, the outer shell is provided with an annular component, and the lower edge of the annular component is the liquid level indicator.

[0043] This embodiment provides a specific implementation of a liquid level indicator. Specifically, a ring-shaped component is provided on the outer casing, with its lower edge serving as the liquid level indicator. No additional grooving or marking is required; simply fitting the ring-shaped component onto the outside of the casing indicates the maximum permissible liquid level when the inner liner is not installed. Because the liquid level indicator effectively prevents cleaning fluid spillage, the ring-shaped component is less prone to damage and can be used as a liquid level indicator for an extended period. Furthermore, the ring-shaped scale design allows users to view the liquid level indicator from various angles, eliminating the need to search for a fixed location, thus simplifying user operation.

[0044] According to another aspect, the present invention provides a cleaning brush, including a brush rod and a brush head. The brush rod includes an outer rod and a piston rod and a piston connected to each other inside the outer rod. The piston rod and the piston slide inside the outer rod to draw cleaning liquid into the outer rod.

Two adjacent first rod segments are detachably connected, and two adjacent second rod segments are detachably connected.

[0045] The cleaning brush provided by this utility model includes a brush rod and a brush head. The brush rod includes an outer rod and a piston rod and a piston connected to each other inside the outer rod. The piston rod and piston can slide inside the outer rod and can draw cleaning liquid into the outer rod for storage. Specifically, the outer rod includes at least two first rod segments, and the piston rod includes at least two second rod segments. Adjacent first rod segments are detachably connected, and adjacent second rod segments are also detachably connected. This facilitates the selection of a certain number of rod segments to assemble a cleaning brush suitable for user operation, and also facilitates the disassembly of some rod segments for simple maintenance of the cleaning brush's interior.

[0046] According to the present invention, a cleaning brush is provided in which one of two adjacent second rod segments is provided with a plurality of elastic hooks and the other of the two adjacent second rod segments is provided with a first locking head. When the two second rod segments approach each other, the first locking head can drive the plurality of elastic hooks to disperse and then converge, thereby locking the first locking head.

[0047] This embodiment provides a specific implementation method for connecting two adjacent second pole segments. Specifically, one of the two adjacent second pole segments is provided with multiple elastic hooks, and the other is provided with a first locking head. When installing the two second pole segments, the multiple elastic hooks of one second pole segment are brought close to the first locking head of the other second pole segment. When the two second pole segments approach each other, the first locking head can drive the multiple elastic hooks to spread out and then converge, thereby locking the first locking head and realizing the connection between the two second pole segments. The installation method is simple and reliable.

[0048] According to the present invention, a cleaning brush is provided in which one of the two adjacent second rod segments is provided with a second slot and a notch, and the other of the two adjacent second rod segments is provided with a connecting post and a second locking head located at the free end of the connecting post. The entrance of the second slot is located on the side of the second rod segment, and the second locking head is inserted into the second slot through the entrance, and the connecting post is located in the notch.

[0049] This embodiment provides another specific implementation method for connecting two adjacent second segments. Specifically, one of the two adjacent second segments is provided with a second slot and a notch, and the other is provided with a connecting post and a second locking head located at the free end of the connecting post. The entrance of the second slot is located on the side of the second segment. When installing the two second segments, the two second segments are brought close to each other until the second locking head is engaged with the second slot from the entrance of the second slot. At this time, the connecting post is located in the notch. By engaging the second slot with the second locking head and engaging the notch with the connecting post, the two second segments can be firmly connected, preventing the segments from detaching when the user uses the cleaning brush and improving the reliability of the cleaning brush.

[0050] According to the present invention, a cleaning brush has two inlets, which are located on opposite sides of the second slot.

[0051] This embodiment provides a specific implementation of the connection between the second slot and the second locking head. Specifically, the side of the second rod segment is provided with two entrances to the second slot, and the two entrances are located on opposite sides of the second slot. When installing the two second rod segments, the second locking head can be inserted into the second slot through the two entrances.

Detailed Implementation

[0096] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0097] In the description of this utility model, it should be clarified that the terms "vertical", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal", etc., which indicate orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model. They do not mean that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation on this utility model.

[0098] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0099] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0100] The cleaning device and cleaning brush of this utility model are described below with reference to the accompanying drawings.

[0101] In related technologies, the storage area of ​​the cleaning brush is usually set separately from the storage area of ​​the cleaning liquid. For example, the storage area of ​​the cleaning brush and the storage area of ​​the cleaning liquid can be integrally formed but arranged on the left and right. The user can hold the cleaning brush, dip it into the storage area of ​​the cleaning liquid, and clean the stain. In order to further pour or spray the cleaning liquid onto the stain, the user usually uses an additional container to hold the cleaning liquid. The user switches between holding the cleaning liquid container and the cleaning brush so that after pouring or spraying the cleaning liquid, the user can use the cleaning brush to clean.

[0102] When users need to clean multiple stains, they have to repeat the above steps of first manually holding the container to pour or spray the cleaning solution, and then switching to the cleaning brush for cleaning. The cleaning operation is inconvenient, the user experience is poor, and the cleaning efficiency is low.

[0103] To address the aforementioned issues, this utility model provides a cleaning device and a cleaning brush, which is designed to hold cleaning fluid in a brush holder. When the cleaning brush is placed inside the brush holder, it can absorb the cleaning fluid contained in the brush holder, allowing the user to directly hold the cleaning brush and use the absorbed cleaning fluid for cleaning. This facilitates the user's cleaning operation and effectively improves the user experience and cleaning efficiency.

[0104] According to one aspect, the present invention provides a cleaning device. Figure 1 This is one of the structural schematic diagrams of the cleaning device provided by this utility model. Figure 2 This is the second structural schematic diagram of the cleaning device provided by this utility model. Figure 2 This is a cross-sectional schematic diagram of the cleaning device, such as... Figure 1 and Figure 2 As shown, the cleaning device includes a cleaning brush 10 and a brush base 20. The brush base 20 is provided with a cleaning liquid storage chamber 201, a cleaning brush storage chamber 202, and a liquid extraction channel 203. The liquid extraction channel 203 is connected to the cleaning liquid storage chamber 201. The cleaning brush 10 can extract the cleaning liquid in the cleaning liquid storage chamber 201 into the cleaning brush 10 through the liquid extraction channel 203.

[0105] Optionally, the aforementioned cleaning brushes, such as toilet brushes and pot brushes, can also be applied to other cleaning scenarios, and this application does not impose any restrictions on them.

[0106] For example, after the cleaning brush 10 is placed into the cleaning brush storage cavity 202, the cleaning fluid in the cleaning fluid storage cavity 201 can be taken out into the cleaning brush 10 through the liquid extraction channel 203. In this case, for example, the liquid extraction channel 203 is set in the cleaning brush storage cavity 202. Alternatively, the cleaning fluid in the cleaning fluid storage cavity 201 can be taken out into the cleaning brush 10 directly through the liquid extraction channel 203 on the cleaning device without being placed in the cleaning brush storage cavity 202. This application does not impose any restrictions.

[0107] The cleaning device provided by this utility model includes a cleaning brush 10 and a brush holder 20. The brush holder 20 is used to accommodate and place the cleaning brush 10. Specifically, the brush holder 20 is provided with a cleaning liquid storage cavity 201, a cleaning brush storage cavity 202, and a liquid dispensing channel 203. The cleaning brush 10 can be placed in the cleaning brush storage cavity 202, and the cleaning brush 10 can also be connected to the cleaning liquid storage cavity 201 through the liquid dispensing channel 203, so that the cleaning liquid stored in the cleaning liquid storage cavity 201 can be taken out into the cleaning brush 10 through the liquid dispensing channel 203. When using the cleaning brush 10, the user can directly use the cleaning liquid in the cleaning brush 10 and use the cleaning brush 10 to clean the stains. The user does not need to frequently switch between holding the cleaning liquid container and the cleaning brush 10 during the cleaning process, which effectively improves the user experience and cleaning efficiency.

[0108] In some embodiments, a specific implementation of the cleaning brush 10 is provided. For example... Figure 2 As shown, the cleaning brush 10 is provided with a suction tube 101, which extends into the liquid extraction channel 203 to draw the cleaning liquid in the cleaning liquid storage chamber 201 into the cleaning brush 10.

[0109] Specifically, the cleaning brush 10 is equipped with a straw 101. The cleaning brush 10 connects to the cleaning liquid storage chamber 201 by extending the straw 101 into the liquid dispensing channel 203. The cleaning liquid in the cleaning liquid storage chamber 201 can be drawn into the cleaning brush 10. By setting the straw 101 to directly extend into the cleaning liquid for suction, the cleaning brush 10 can effectively draw in the cleaning liquid, reduce air intake, increase the amount of cleaning liquid drawn into the cleaning brush 10, and facilitate user use.

[0110] It should be noted that when the user puts the cleaning brush 10 into the cleaning brush storage cavity 202, the user should be careful to insert the straw 101 on the cleaning brush 10 into the liquid dispensing channel 203. At this time, the liquid dispensing channel 203 can connect the cleaning liquid storage cavity 201 and the cleaning brush 10, so that the cleaning brush 10 can use the straw 101 to draw the cleaning liquid in the cleaning liquid storage cavity 201 through the liquid dispensing channel 203.

[0111] In some embodiments, a specific implementation of the location of the liquid dispensing channel 203 and the suction tube 101 on the cleaning device is provided. Figure 3This is the third schematic diagram of the cleaning device provided by this utility model. Figure 4 This is a schematic diagram of the cleaning brush in the cleaning device provided by this utility model, as shown below. Figure 3 and Figure 4 As shown, the liquid collection channel 203 is located on the bottom surface of the cleaning brush storage cavity 202. The cleaning brush 10 includes a brush rod 102 and a brush head 103. The suction tube 101 is located on the brush head 103 at a position opposite to the liquid collection channel 203.

[0112] Specifically, the liquid dispensing channel 203 is located on the bottom surface of the cleaning brush storage cavity 202. The cleaning brush 10 includes a brush handle 102 and a brush head 103. The suction tube 101 is located on the brush head 103 at a position opposite to the liquid dispensing channel 203. When the user holds the brush handle 102 and inserts the brush head 103 into the cleaning brush storage cavity 202, the suction tube 101 on the brush head 103 will extend into the liquid dispensing channel 203 on the bottom surface of the cleaning brush storage cavity 202 to communicate with the cleaning liquid storage cavity 201 and effectively draw out the cleaning liquid. The position of the suction tube can avoid the suction tube occupying the lateral position on the brush head, which is conducive to setting more cleaning bristles on the brush head, thus improving the cleaning effect and cleaning efficiency.

[0113] It should be noted that the present invention places the straw 101 on the brush head 103 in a position opposite to the liquid dispensing channel 203, which also helps the user to smoothly insert the straw 101 on the cleaning brush 10 into the liquid dispensing channel 203 when placing the cleaning brush 10 into the cleaning brush storage cavity 202, so as to ensure that the cleaning brush 10 can use the straw 101 to draw up the cleaning liquid.

[0114] For example, an opening with a radial dimension larger than that of the liquid dispensing channel 203 can also be provided at the top of the liquid dispensing channel 203, so that the straw 101 can be guided into the liquid dispensing channel 203 through the opening, which is convenient for user operation.

[0115] In some embodiments, a specific implementation of the brush head 103 is provided. For example... Figure 3 and Figure 4 As shown, the brush head 103 includes bristles 1031 and bristle carrier 1032. The bristle carrier 1032 is provided with an embedding groove A with the opening facing downward. When the brush head 103 is placed into the cleaning brush storage cavity 202, the liquid extraction channel 203 is embedded in the embedding groove A, and the suction tube 101 is disposed in the embedding groove A.

[0116] Optionally, the bristles 1031 mentioned above can be, for example, nylon bristles, metal wire bristles, mixed bristles, etc., to be suitable for different types of cleaning scenarios.

[0117] Optionally, the bristle carrier 1032 is used to support the bristles 1031. The bristle carrier 1032 can be integrally formed with the brush handle 102 or detachably connected. The user can operate the bristle carrier 1032 to drive the bristles 1031 for cleaning by holding the brush handle 102.

[0118] Specifically, the brush head 103 includes bristles 1031 and bristle carrier 1032. The bristles 1031 are disposed on the bristle carrier 1032, and the bristle carrier 1032 is provided with an insert groove A facing downward. When the user holds the brush handle 102 and puts the brush head 103 into the cleaning brush storage cavity 202, the liquid dispensing channel 203 provided on the bottom surface of the cleaning brush storage cavity 202 will be inserted into the insert groove A, and the straw 101 is disposed in the insert groove A, so that the straw 101 can extend into the liquid dispensing channel 203 to dispense liquid. In addition, since the liquid dispensing channel 203 extends upward and is inserted into the insert groove A, more cleaning liquid can be stored.

[0119] In other embodiments, another specific implementation of the location of the liquid dispensing channel 203 and the suction tube 101 on the cleaning device is provided. The liquid dispensing channel 203 is, for example, still located on the bottom surface of the cleaning brush storage cavity 202, but next to the brush head 103. Correspondingly, the suction tube 101 extends from the side of the bristle carrier 1032 and bends downward. When the user uses the device, as the brush head 103 is placed into the cleaning brush storage cavity 202 by holding the brush handle 102, the suction tube 101 on the brush head 103 can extend into the liquid dispensing channel 203 to draw the cleaning liquid from the cleaning liquid storage cavity 201.

[0120] In some embodiments, a specific implementation of the straw 101 is provided. For example... Figure 4 As shown, the lower end B of the straw 101 is higher than or flush with the opening of the embedding groove A.

[0121] Specifically, the lower end B of the straw 101 is higher than or level with the opening of the embedding groove A. The figure shows an example where the lower end of the straw 101 is basically level with the opening of the embedding groove A, so as to avoid the straw 101 being too long and affecting the user's normal use of the cleaning brush 101.

[0122] It should be noted that the lower end B of the straw 101 can also be set below the opening of the embedded groove A. In this case, the cleaning brush 101 can also cooperate normally with the brush seat 20 to achieve self-absorption of cleaning liquid and clean through the bristles 1031 around the straw 101. This application does not impose any restrictions.

[0123] In some embodiments, a specific implementation of the brush holder 20 is provided. Figure 5 This is one of the structural schematic diagrams of the brush holder in the cleaning device provided by this utility model, such as... Figure 5As shown, the brush holder 20 is provided with an adapter tube 204. The suction tube 101 extends into the liquid collection channel 203 and can be connected to the top of the adapter tube 204 to draw cleaning liquid through the adapter tube 204.

[0124] For example, the bottom end of the adapter tube 204 can be located at the bottom of the cleaning fluid storage cavity 201, so that the cleaning brush 10 can connect to the adapter tube 204 using the suction tube 101, and then draw the cleaning fluid in the cleaning fluid storage cavity 201 until there is no cleaning fluid left at the bottom of the cleaning fluid storage cavity 201, that is, the cleaning fluid can be fully drawn.

[0125] Optionally, the bottom end of the adapter tube 204 may be provided with a triangular or rectangular cut so that when the adapter tube 204 contacts the bottom of the cleaning fluid storage cavity 201, the cleaning fluid can also flow into the adapter tube 204 through the cut and then be drawn into the cleaning brush 10. This avoids the cleaning brush 10 having difficulty drawing up the cleaning fluid when the bottom end of the adapter tube 204 contacts the bottom of the cleaning fluid storage cavity 201, making it easier for the user to use.

[0126] It should be noted that the shape of the cut is not limited in this embodiment of the utility model. The example only uses a triangular or rectangular cut. Other shapes of cuts can also be used, as long as the cleaning fluid can be drawn into the cut through the cut when the bottom end of the adapter tube 204 is in contact with the bottom of the cleaning fluid storage cavity 201.

[0127] Specifically, the brush holder 20 is provided with an adapter tube 204. After the suction tube 101 on the brush head 103 is inserted into the liquid dispensing channel 203, it can be connected to the top of the adapter tube 204 to draw the cleaning liquid through the adapter tube 204. This avoids the problem that the suction tube 101 is too short, making it difficult to effectively contact the cleaning liquid and thus difficult to draw the cleaning liquid. The adapter tube 204 in the brush holder 20 can effectively connect to and draw the cleaning liquid in the cleaning liquid storage cavity 201. Even with a shorter suction tube 101 to avoid affecting the brushing effect of the cleaning brush 10, it can still ensure that the suction tube 101 can effectively draw the cleaning liquid.

[0128] In some embodiments, a specific implementation of setting the transfer tube 204 is provided. Figure 6 This is one of the structural diagrams of the fixing structure in the cleaning device provided by this utility model, such as... Figure 6 As shown, the brush holder 20 is also provided with a fixing structure 205, which is used to fix the bottom end of the adapter tube 204 at the lowest position of the cleaning liquid.

[0129] It should be noted that the lowest point of the aforementioned cleaning fluid can be, for example, the bottom of the cleaning fluid storage chamber 201.

[0130] Specifically, the brush holder 20 is also provided with a fixing structure 205, which is used to fix the bottom end of the adapter tube 204 at the lowest position of the cleaning liquid, so as to avoid the bottom end of the adapter tube 204 not sinking to the bottom, which would make it difficult to fully absorb the cleaning liquid through the adapter tube 204. This application fixes the bottom end of the adapter tube 204 by fixing the fixing structure 205, so that the suction tube 101 on the brush head 103 can fully absorb the cleaning liquid with the help of the adapter tube 204.

[0131] In some embodiments, a specific implementation of the fixing structure 205 is provided. For example... Figure 6 As shown, the fixing structure 205 includes a support member 2051 and a fixing member 2052. The support member 2051 is fixed at the lowest position and supports the bottom end of the adapter pipe 204 so that a liquid inlet channel C is left below the bottom end of the adapter pipe 204 to facilitate the entry of cleaning fluid into the adapter pipe 204. The fixing member 2052 is provided on the support member 2051 and is inserted into the bottom end of the adapter pipe 204.

[0132] Specifically, the fixing structure 205 includes a support member 2051 and a fixing member 2052. The support member 2051 is fixed to the lowest position of the cleaning fluid (e.g., fixed to the bottom of the cleaning fluid storage cavity 201) and supports the bottom end of the adapter 204 so that an inlet channel for the cleaning fluid to enter the adapter 204 is left below the bottom end of the adapter 204. The fixing member 2052 is provided on the support member 2051 and inserted into the bottom end of the adapter 204 to fix the bottom end of the adapter 204 relatively around the support member 2051, preventing the adapter 204 from moving with the shaking of the cleaning fluid in the cleaning fluid storage cavity 201, so that the bottom end of the adapter 204 can be effectively aligned with the lowest position of the cleaning fluid for easy full liquid intake.

[0133] In some embodiments, a specific implementation of the support member 2051 and the fastener 2052 is provided. Figure 7 This is the second structural schematic diagram of the fixing structure in the cleaning device provided by this utility model. Figure 8 This is an exploded view of the fixing structure in the cleaning device provided by this utility model, as shown below. Figure 7 and Figure 8 As shown, the support member 2051 is a first cross-shaped structure. The same side of the four plates of the first cross-shaped structure is fixed to the lowest position. The fixing member 2052 is connected to the other side of the four plates of the first cross-shaped structure. The liquid inlet channel C is between any two adjacent plates among the four plates.

[0134] and / or

[0135] The fixing member 2052 is a second cross-shaped structure, and the channels between two adjacent plates of the four plates of the second cross-shaped structure are all connected to the liquid inlet channel C.

[0136] Specifically, for the support member 2051, the support member 2051 can be a first cross-shaped structure. The same side of the four plates of the first cross-shaped structure is fixed to the lowest position. The other side of the four plates can support the bottom end of the adapter pipe 204. Furthermore, there are liquid inlet channels C between any two adjacent plates among the four plates. Cleaning liquid can be drawn from below the bottom end of the adapter pipe 204 through these liquid inlet channels C.

[0137] For the fastener 2052, the fastener 2052 can be connected to the other side of the four plates of the first cross-shaped structure to fix the bottom end of the adapter 204. Alternatively, the fastener 2052 can also be a second cross-shaped structure, in which the channels between two adjacent plates of the four plates of the second cross-shaped structure are connected to the liquid inlet channel C, so that cleaning liquid can be drawn from below the bottom end of the adapter 204.

[0138] The support 2051 and fastener 2052 in this application have simple structure, use less material and have low cost, but can effectively support and fix the bottom end of the adapter pipe 204, and leave a channel for absorbing cleaning fluid, so that the cleaning brush 10 can effectively absorb cleaning fluid.

[0139] It should be noted that the aforementioned support member 2051 can also be configured in other shapes besides the cross-shaped structure. For example, several support plates can be added to the cross-shaped structure to jointly support the bottom end of the adapter pipe 204 and leave a liquid inlet channel C.

[0140] It should also be noted that the aforementioned fastener 2052 can also be configured in other shapes besides the cross-shaped structure, such as a fixed post with a radial dimension smaller than the radial dimension of the bottom end of the adapter 204, so that the cleaning fluid can be drawn into the adapter 204; the fixed post can be integrally formed with the support 2051 or detachably connected, which is not limited in this application.

[0141] In some embodiments, a specific implementation of the liquid dispensing channel 203 is provided. For example... Figure 2 As shown, the top of the liquid dispensing channel 203 extends upward and is provided with an anti-overflow channel D. The anti-overflow channel D is used to prevent the cleaning liquid from overflowing when the straw 101 is inserted into the liquid dispensing channel 203 and the liquid level of the cleaning liquid rises.

[0142] Specifically, an anti-overflow channel D is provided at the top of the liquid dispensing channel 203. When the straw 101 is inserted into the cleaning liquid in the liquid dispensing channel 203, the liquid level of the cleaning liquid will rise because the straw will occupy some space. By designing the anti-overflow channel D, this application can effectively prevent the cleaning liquid from overflowing to the outside of the liquid dispensing channel 203.

[0143] In some embodiments, a specific implementation of setting the length of the overflow channel D is provided. The length of the overflow channel is in the range of 2mm to 6mm.

[0144] Specifically, based on the dimensions of the straw 101 and the liquid dispensing channel 203, the height that the cleaning liquid may rise when the straw 101 is inserted into the liquid dispensing channel 203 can be calculated. Based on this, the length of the anti-overflow channel D in this application is set to be in the range of 2mm to 6mm, which can effectively prevent the cleaning liquid from overflowing to the outside of the liquid dispensing channel 203 without affecting the normal use of the cleaning device.

[0145] In some embodiments, a specific implementation of the location of the liquid dispensing channel 203 is provided. Figure 9 This is the second schematic diagram of the brush holder in the cleaning device provided by this utility model, as shown below. Figure 2 , 3 As shown in Figure 8, the liquid extraction channel 203 is located inside the cleaning brush storage cavity 202. The lower end of the liquid extraction channel 203 is connected to the cleaning liquid storage cavity 201, and the upper end of the liquid extraction channel 203 extends to the top of the cleaning liquid storage cavity 201.

[0146] Specifically, the liquid dispensing channel 203 is located inside the cleaning brush storage cavity 202. The lower end of the liquid dispensing channel 203 is connected to the cleaning liquid storage cavity 201, and the upper end extends to the top of the cleaning liquid storage cavity 201. This arrangement allows the liquid dispensing channel 203 to connect the cleaning liquid storage cavity 201 and the cleaning brush 10 while minimizing the use of additional space outside the brush holder 20, thus saving space in the entire cleaning device and making it convenient to use. At the same time, the upper end of the liquid dispensing channel 203 extends to the top of the cleaning liquid storage cavity 201, which allows the cleaning liquid storage cavity 201 to store more cleaning liquid without the need for a valve at the upper end of the liquid dispensing channel 203. For example, the liquid level can be brought close to the top of the cleaning liquid storage cavity 201, as long as it is lower than the upper end of the liquid dispensing channel 203, and the cleaning liquid will not overflow.

[0147] In some embodiments, another specific implementation of the brush holder 20 is provided. Figure 10 This is the third schematic diagram of the brush holder structure in the cleaning device provided by this utility model, as shown below. Figures 2 to 10 As shown, the brush holder 20 includes a shell 206 and an inner liner 207. The cleaning fluid storage cavity 201 is located between the shell 206 and the inner liner 207, and the cleaning brush storage cavity 202 is located in the inner liner 207.

[0148] Specifically, the brush holder 20 includes a housing 206 and an inner liner 207. The cleaning fluid storage cavity 201 is located between the housing 206 and the inner liner 207, and the cleaning brush storage cavity 202 is located in the inner liner 207. Compared to setting up two additional parts for storing cleaning fluid and cleaning brush 10 respectively, this application effectively utilizes the specific structure of the brush holder 20 to separate the cleaning fluid storage cavity 201 and the cleaning brush storage cavity 202, effectively saving the space of the entire cleaning device and making it convenient to use.

[0149] In some embodiments, a specific implementation of mounting the brush holder 20 is provided. For example... Figures 2 to 10 As shown, the inner liner 207 is detachably connected to the outer shell 206. When the inner liner 207 is installed into the outer shell 206, the inner liner 207 presses down on the cleaning fluid, causing the liquid level of the cleaning fluid to rise. The liquid extraction channel 203 is located inside the inner liner 207. The lower end of the liquid extraction channel 203 communicates with the cleaning fluid storage cavity 201, and the upper end of the liquid extraction channel 203 extends towards the opening of the inner liner 207 to buffer the rising liquid level of the cleaning fluid and prevent the cleaning fluid from overflowing from the upper end of the liquid extraction channel 203.

[0150] Specifically, the inner liner 207 is detachably connected to the outer shell 206, allowing users to directly add cleaning fluid into the outer shell 206 and install the inner liner 207 into the outer shell 206. When the inner liner 207 is installed into the outer shell 206, the inner liner 207 presses down on the cleaning fluid stored in the outer shell 206, causing the liquid level of the cleaning fluid to rise. The liquid dispensing channel 203 is located inside the inner liner 207, with its lower end connected to the cleaning fluid storage cavity 201 and its upper end extending towards the opening of the inner liner 207. When the liquid level of the cleaning fluid rises, the extension of the liquid dispensing channel 203 can buffer the rising liquid level, preventing the cleaning fluid from overflowing from the upper end of the liquid dispensing channel 203. This effectively prevents the cleaning fluid from overflowing during the installation of the inner liner 207, improving the user experience.

[0151] In some embodiments, a specific implementation is provided for the connection between the inner liner 207 and the outer shell 206. For example... Figures 2 to 10 As shown, the inner liner 207 and the outer shell 206 are connected by a rotary connection structure.

[0152] Specifically, the inner liner 207 and the outer shell 206 are connected by a rotary connection structure. The rotary connection allows the inner liner 207 to be more securely installed on the outer shell 206, preventing the inner liner 207 from being pulled out when the user pulls the cleaning brush 10 out of the brush holder 20. In addition, compared with directly connecting the inner liner 207 and the outer shell 206 vertically, the rotary connection can, to some extent, prevent the cleaning liquid from being squeezed out due to excessive force when the user installs it vertically, further improving the user experience.

[0153] In some embodiments, a specific implementation of the rotary connection structure is provided. Figure 11 This is a schematic diagram of the outer shell of the cleaning device provided by this utility model. Figure 12 This is a schematic diagram of the inner liner of the cleaning device provided by this utility model, as shown below. Figure 11 and Figure 12 As shown, the rotary connection structure includes a first sliding groove 2061 disposed on the inner surface of the outer shell 206 and a locking block 2071 disposed on the outer surface of the inner liner 207. The first sliding groove 2061 includes a first locking groove E and a guide groove F. The inner liner 207 and the outer shell 206 can rotate relative to each other so that the locking block 2071 can slide from the guide groove F into the first locking groove E for locking.

[0154] Specifically, the rotary connection structure includes a first sliding groove 2061 on the inner surface of the outer shell 206 and a locking block 2071 on the outer surface of the inner liner 207. The first sliding groove 2061 includes a first locking groove E and a guide groove F. When the inner liner 207 and the outer shell 206 rotate relative to each other, the locking block 2071 can slide from the guide groove F into the first locking groove E for locking. The setting of the guide groove F helps the user to more smoothly achieve the locking between the locking block 2071 and the first locking groove E through rotation. The structure is simple and convenient to use.

[0155] In some embodiments, a specific implementation of the housing 206 is provided. Figure 13 This is the fourth schematic diagram of the brush holder structure in the cleaning device provided by this utility model, as shown below. Figures 2 to 13 As shown, the outer shell 206 is provided with a liquid level indicator G, which is used to indicate the maximum liquid level height when the inner liner 207 is not installed in the outer shell 206, so as to avoid the liquid level of the cleaning fluid being higher than the preset liquid level height after the inner liner 207 is installed in the outer shell 206.

[0156] Specifically, since the inner liner 207 will compress the cleaning fluid in the outer shell 206 when it is installed into the outer shell 206, causing the liquid level of the cleaning fluid to rise, in order to prevent the cleaning fluid from overflowing the outer shell 206, this application provides a liquid level indicator G on the outer shell 206 to indicate the maximum liquid level when the inner liner 207 is not installed into the outer shell 206, so as to prevent the liquid level of the cleaning fluid from being higher than the preset liquid level after the inner liner 207 is installed into the outer shell 206, which would easily cause the cleaning fluid to overflow. When using the product, the user can pour in cleaning fluid as low as possible below the liquid level indicator G to ensure that the cleaning fluid does not overflow.

[0157] In some embodiments, a specific implementation of the liquid level indicator G is provided. For example... Figures 2 to 13 As shown, the outer shell 206 is fitted with an annular component 2062, and the lower edge of the annular component 2062 is the liquid level mark G.

[0158] Specifically, an annular component 2062 is provided on the outer casing 206. The lower edge of the annular component 2062 is the liquid level indicator G. No additional grooving or marking is required. Simply fitting the annular component 2062 on the outside of the outer casing 206 is sufficient to indicate the maximum liquid level that the inner liner 207 can be filled into when it is not installed in the outer casing 206. Since the liquid level indicator G can effectively prevent the cleaning fluid from overflowing, the annular component 2062 is not easily damaged and its lower edge can be used as the liquid level indicator for a long time. The design of the annular scale also makes it easy for users to view the liquid level indicator G from various angles without having to search for a fixed position of the indicator, which is convenient for users.

[0159] According to another aspect, the present invention provides a cleaning brush 10. Figure 14 This is one of the structural schematic diagrams of the cleaning brush provided by this utility model. Figure 15 This is an exploded view of the cleaning brush provided by this utility model, as shown below. Figures 1 to 15 As shown, the cleaning brush 10 includes a brush rod 102 and a brush head 103. The brush rod 102 includes an outer rod 1021 and a piston rod 1022 and a piston 1023 connected to each other inside the outer rod 1021. The piston rod 1022 and the piston 1023 slide inside the outer rod 1021 to draw cleaning liquid into the outer rod 1021. The outer rod 1021 includes at least two first rod segments 10211, and the piston rod 1022 includes at least two second rod segments 10221. Two adjacent first rod segments 10211 and two adjacent second rod segments 10221 are detachably connected.

[0160] Specifically, the user can operate the piston rod 1022 and piston 1023 to slide within the outer rod 1021 via an operating component. Specifically, the piston rod 1022 can slide relative to the outer rod 1021 to drive the piston 1023 to slide within the outer rod 1021. For example, when the piston 1023 slides upward within the outer rod 1021, air or cleaning fluid can be drawn in; when the piston 1023 slides downward within the outer rod 1021, air can be expelled or cleaning fluid can be sprayed out.

[0161] Optionally, at least two first segments 10211 can be directly engaged and connected by the engaging structure on both sides of the segment, or rotated and connected by the rotating structure on both sides of the segment. This application does not impose any restrictions.

[0162] The cleaning brush 10 provided by this utility model includes a brush rod 102 and a brush head 103. The brush rod 102 includes an outer rod 1021 and a piston rod 1022 and a piston 1023 connected to each other inside the outer rod 1021. The piston rod 1022 and the piston 1023 can slide inside the outer rod 1021 and can draw cleaning liquid into the outer rod 1021 for storage. Specifically, the outer rod 1021 includes at least two first rod segments 10211, and the piston rod 1022 includes at least two second rod segments 10221. Two adjacent first rod segments 10211 are detachably connected, and two adjacent second rod segments 10221 are also detachably connected. This makes it easy to select a certain number of rod segments to assemble a cleaning brush 10 suitable for user operation, and also makes it easy to disassemble some rod segments for simple maintenance of the cleaning brush 10.

[0163] In some embodiments, a specific implementation is provided for the connection between two adjacent second segments 10221. Figure 16 This is a schematic diagram of the connection between the two second rod segments in the cleaning brush provided by this utility model. Figure 17 This is an exploded view of the cleaning brush provided by this utility model between the two second rod segments, as shown in the diagram. Figure 16 and Figure 17 As shown, one of the two adjacent second rod segments 10221 is provided with multiple elastic hooks H, and the other of the two adjacent second rod segments 10221 is provided with a first locking head I. When the two second rod segments 10221 approach each other, the first locking head I can drive the multiple elastic hooks H to disperse and then converge, thereby locking the first locking head I.

[0164] Specifically, one of two adjacent second rod segments 10221 is provided with multiple elastic hooks H, and the other is provided with a first locking head I. When installing the two second rod segments 10221, one side of the multiple elastic hooks H of one second rod segment 10221 is brought close to the side of the first locking head I of the other second rod segment 10221. When the two second rod segments 10221 approach each other, the first locking head I can drive the multiple elastic hooks H to disperse and then converge, thereby locking the first locking head I and realizing the connection between the two second rod segments 10221. The installation method is simple and reliable.

[0165] In some embodiments, another specific implementation is provided for the connection between two adjacent second segments 10221. Figure 18 This is a structural schematic diagram of one side of the second rod section in the cleaning brush provided by this utility model. Figure 19 This is a structural schematic diagram of the other side of the second rod segment in the cleaning brush provided by this utility model, as shown below. Figure 18 and Figure 19As shown, one of the two adjacent second rod segments 10221 is provided with a second slot J and a notch K, and the other of the two adjacent second rod segments 10221 is provided with a connecting post L and a second locking head M located at the free end of the connecting post L. The entrance N of the second slot J is located on the side of the second rod segment 10221, and the second locking head M is inserted into the second slot J through the entrance N, and the connecting post L is located in the notch K.

[0166] Specifically, one of the two adjacent second rod segments 10221 is provided with a second slot J and a notch K, and the other is provided with a connecting post L and a second locking head M located at the free end of the connecting post L. The entrance N of the second slot J is located on the side of the second rod segment 10221. When installing the two second rod segments 10221, the two second rod segments 10221 move closer to each other until the second locking head M is inserted into the second slot J from the entrance N of the second slot J. At this time, the connecting post L is located in the notch K. By engaging the second slot J with the second locking head M and engaging the notch K with the connecting post L, the two second rod segments 10221 can be firmly connected, avoiding the rod segments from detaching when the user uses the cleaning brush 10, thus improving the reliability of the cleaning brush 10.

[0167] In some embodiments, a specific implementation method is provided for the connection between the second card slot J and the second card header M. For example... Figure 18 and Figure 19 As shown, there are two inlets N, which are located on opposite sides of the second slot J.

[0168] Specifically, the second rod segment 10221 has two entrances N on its side for the second slot J, and the two entrances N are located on opposite sides of the second slot J. When installing the two second rod segments 10221, the second locking head M can be inserted into the second slot J from the two entrances N. The two entrances N effectively restrict the movable direction of the second locking head M, which is conducive to the smoother installation of the second locking head M in the second slot J and makes the installation more convenient.

[0169] In some embodiments, a specific implementation is provided for the piston rod 1022 to move relative to the outer rod 1021. Figure 20 This is the second structural schematic diagram of the cleaning brush provided by this utility model, as shown below. Figures 14 to 18 As shown, a push button P is provided on the outer side of the outer rod 1021, and a second sliding groove Q is provided on the outer rod 1021. The push button P passes through the second sliding groove Q and is connected to the piston rod 1022. Pushing the push button P along the second sliding groove Q can drive the piston rod 1022 to slide inside the outer rod 1021.

[0170] Specifically, a push button P is provided on the outer side of the outer rod 1021, and a second sliding groove Q is provided on the outer rod 1021. The push button P can pass through the second sliding groove Q and connect to the piston rod 1022. The user can push the push button P to move on the second sliding groove Q. When moving, the push button P will drive the piston rod 1022 to slide inside the outer rod 1021. The setting of the second sliding groove Q effectively limits the movable range of the piston rod 1022 inside the outer rod 1021, ensuring that the cleaning brush 10 can work normally, and the setting of the push button P is convenient for user operation.

[0171] For example, when the user pushes the push button P to slide upward along the second slide groove Q, the push button P will drive the piston rod 1022 to move upward, thereby driving the piston 1023 to slide upward within the outer rod 1021, which can draw in air or cleaning fluid; when the user pushes the push button P to slide downward along the second slide groove Q, the push button P will drive the piston rod 1022 to move downward, thereby driving the piston 1023 to slide downward within the outer rod 1021, which can expel air or spray out cleaning fluid.

[0172] In some embodiments, a specific implementation of the piston rod 1022 is provided. Figure 21 This is the third structural schematic diagram of the cleaning brush provided by this utility model, as shown below. Figures 14 to 19 As shown, the piston rod 1022 is provided with a blocking part R, which is used to block the second slide groove Q from the inside of the second slide groove Q when the push button P slides along the second slide groove Q to any position.

[0173] Specifically, the piston rod 1022 is provided with a blocking part R. When the push button P slides along the second slide groove Q to any position, the blocking part R can block the second slide groove Q from the inside of the second slide groove Q. This prevents the cavity or structure inside the outer rod 1021 from being exposed when the push button P slides along the second slide groove Q to any position, making the structure of the brush rod 102 simpler and more regular.

[0174] In some embodiments, a specific implementation of the occlusion portion R is provided. For example... Figures 14 to 19 As shown, the surface of the shielding part R facing the second sliding groove Q is an arc surface, and the arc surface slides in contact with the inner surface of the outer rod 1021.

[0175] Specifically, the surface of the shielding part R facing the second slide groove Q is an arc surface, which can slide and engage with the inner surface of the outer rod 1021. By setting the surface of the shielding part R facing the second slide groove Q to an arc surface, it helps the shielding part R and the inner surface of the outer rod 1021 to have a near-seamless contact, so as to play a better shielding role. In addition, the arc surface design also helps the shielding part R and the inner surface of the outer rod 1021 to slide more smoothly relative to each other.

[0176] In some embodiments, a specific implementation of the brush head 103 is provided. Figure 22 This is the fourth structural schematic diagram of the cleaning brush provided by this utility model, as shown below. Figures 14 to 20 As shown, the brush head 103 is provided with a straw 101, which is used to insert into the cleaning liquid to draw the cleaning liquid.

[0177] Specifically, the brush head 103 is equipped with a straw 101, which is used to insert into the cleaning solution and draw the cleaning solution into the cleaning brush 10. Users do not need to hold other containers to pour out the cleaning solution. They can directly use the cleaning solution drawn into the cleaning brush 10 and use the cleaning brush 10 to clean, which is convenient for users.

[0178] In some embodiments, a specific implementation is provided for positioning the straw 101 on the brush head 103. For example... Figures 14 to 20 As shown, the brush head 103 has a receiving groove S recessed towards the brush rod 102 at one end away from the brush rod 102, and the suction tube 101 is disposed in the receiving groove S.

[0179] Specifically, the brush head 103 has a receiving groove S recessed towards the brush handle 102 at one end away from the brush handle 102. The straw 101 is located in the receiving groove S. By setting the receiving groove S in the existing space of the cleaning brush 10 to accommodate the straw 101, it is possible to avoid setting an additional straw 101 and occupying brush head space, thus ensuring the cleaning effect of the cleaning brush 10.

[0180] The following examples illustrate the cleaning device and cleaning brush provided by this utility model.
