Description

Technical Field

[0001] The utility model relates to the field of toilet cleaning, in particular to a toilet brush head and a toilet brush. Background Art

[0002] There are many kinds of toilet brushes on the market. Sponge-headed toilet brushes are favored by users because of their good water absorption and cleaning performance. The brush heads of existing toilet brushes are usually glued to a connecting head on one side of the brush body, and the other side of the brush body is used for cleaning. In addition, since the brush heads are often in contact with water, the firmness of the glue is greatly reduced, making the brush heads easy to fall off. When the user wipes the toilet vigorously, the sponge head will generate a large friction with the surface of the toilet, which can easily cause the sponge head to tear from the glued position and fall off. At the same time, the existing toilet brush heads need to go through at least positioning, gluing, and waiting for solidification during assembly, and the assembly process is relatively cumbersome and time-consuming. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] The utility model mainly solves the deficiencies in the prior art, and specifically relates to a toilet brush head, which solves the problem in the prior art that when the brush body and the connecting head of the toilet brush head are connected by gluing, the brush body is easy to fall off or be damaged, and the assembly is relatively cumbersome.

[0005] (II) Technical solution

[0006] In the first aspect, the utility model relates to a toilet brush head, comprising a brush body, a first connecting part and a second connecting part. A penetration part is provided on one side of the first connecting part, and a limiting part is provided on the penetration part. The penetration part is driven to pass through the brush body and cooperate with the second connecting part to connect so that the brush body is clamped between the first connecting part and the second connecting part, and the limiting part is limited on the side of the second connecting part away from the brush body to limit the penetration part from being separated from the second connecting part.

[0007] The advantage is that when installing the brush body, you only need to pass the penetration part of the first connection part from one side of the brush body, and cooperate with the side of the second connection part away from the brush body through the limiting part to clamp the second connection part, so that the brush body can be clamped between the first connection part and the second connection part. The assembly method of the brush body is simple and convenient. At the same time, since the brush body needs to contact the surface of the toilet during cleaning, the brush body will be subjected to greater friction. When only one side of the brush body is fixed, the brush body is easy to fall off during the cleaning process. The connection method of clamping the brush body between the first connection part and the second connection part allows the two opposite sides of the brush body to be fixed. The brush body is fixed on the toilet brush head more firmly and reliably, which can effectively prevent the brush body from detaching or being damaged during cleaning operations, and is not affected by environmental factors, so the user experience is better.

[0008] In an optional implementation, a projection of the limiting portion toward the second connecting portion partially overlaps with the second connecting portion.

[0009] The advantage is that the projection of the limiting part toward the second connecting part partially overlaps with the second connecting part, so that when the penetration part moves toward the second connecting part, the overlapping part between the limiting part and the second connecting part will clamp the limiting part to prevent the limiting part from escaping from the second connecting part.

[0010] In an optional implementation, the limiting portion is circular.

[0011] The advantage is that the limiting part is arranged in a circular shape, so that when the penetration part is rotated at any angle, the penetration part will not fall out of the second connecting part, thereby enhancing the reliability of the brush body installation and facilitating the processing of the limiting part.

[0012] In an optional embodiment, the first connecting portion includes a connecting substrate, and the limiting portion is provided on one side of the connecting substrate, so that the brush body is clamped between the connecting substrate and the limiting portion.

[0013] The advantage is that the connecting substrate can limit the brush body by abutting against one of the side surfaces of the brush body, thereby preventing the brush body from being separated from the penetration direction away from the penetration portion.

[0014] In an optional embodiment, the second connecting portion is provided between the connecting substrate and the limiting portion so that the brush body is clamped between the connecting substrate and the second connecting portion.

[0015] The advantage is that, because the limiting part needs to pass through the brush body, when the limiting part alone is used to limit the insertion direction of the penetration part, the limiting effect is poor and it is easy to fail. Therefore, a second connecting part is provided to effectively limit the brush body in the insertion direction of the penetration part, thereby improving the firmness of the brush body installation.

[0016] In an optional implementation, the maximum width of the connection substrate is smaller than the minimum width of the second connection portion.

[0017] The advantage is that the shape of the second connecting portion is larger than the shape of the connecting base plate, thereby preventing the brush body from forming an upward tendency when being fixed and affecting the cleaning operation of the toilet.

[0018] In an optional implementation, the distance between the connecting substrate and the limiting portion is defined as H, the thickness of the second connecting portion is defined as A, and the thickness of the brush body is defined as B, wherein HA≤B.

[0019] The advantage is that when the distance between the second connecting part and the connecting substrate is smaller than the thickness of the brush body, the connecting substrate will squeeze the brush body when the brush body is fixed, causing the brush body to produce a certain amount of deformation, thereby preventing a gap between the brush body and the second connecting part and the connecting substrate, effectively preventing the brush body from loosening when it is fixed.

[0020] In an optional embodiment, the penetration portion includes a connecting head, the second connecting portion includes a connecting hole, and the connecting head passes through the connecting hole to be connected to the handheld component, so that the brush body is installed in the handheld component.

[0021] The advantage is that the connecting head is used to connect to the handheld part, so that the user can extend the distance between the toilet brush head and the hand when cleaning the toilet, avoid dirty hands, and the user has a better experience when using it.

[0022] In an optional embodiment, the connector is provided with a plurality of vertical edges arranged along the vertical direction, and the shape of the connecting hole matches that of the vertical edges, so that when the connector is inserted into the connecting hole, the vertical edges slide in the connecting hole.

[0023] The advantage is that by setting vertical edges, avoidance spaces will be formed between the vertical edges. When the connecting head passes through the connecting hole, the deformation of the part of the connecting hole corresponding to the vertical edges is larger, and the deformation of the part of the connecting hole corresponding to the avoidance space is smaller. When the shape of the connecting hole matches that of the vertical edges, the deformation of the part of the connecting hole corresponding to the vertical edges is smaller. Therefore, in general, setting vertical edges that match the shape of the connecting hole reduces the deformation of the connecting hole, makes it easier for the connecting head to pass through the connecting hole, and provides a better user experience.

[0024] In an optional embodiment, the connector is spherical.

[0025] The advantage is that the spherical connecting head allows the toilet brush head to be universally rotated when connected to the handheld component to meet different usage operations.

[0026] In an optional embodiment, the second connecting portion is deformed by its own elastic force to limit the separation of the penetration portion and the second connecting portion.

[0027] The advantage is that when the deformation is caused by its own elastic force, there is no need for the user to manually drive the deformation, the assembly method is simple and more efficient, and the penetration part can be clamped by the deformation of the second connecting part to prevent the penetration part from falling out.

[0028] In an optional embodiment, a connecting hole is provided in the middle of the second connecting portion, which is suitable for the penetration portion to pass through the connecting hole and contract through the connecting hole to limit the penetration portion from escaping from the connecting hole.

[0029] The advantage is that the connection hole is provided to cooperate with the penetration part, which makes installation more convenient. It only needs the second connection part to fit tightly with the brush body and the penetration part to pass through the brush body and the connection hole at the same time, so that the brush body can be clamped between the first connection part and the second connection part.

[0030] In an optional embodiment, the connecting hole includes a plurality of strip-shaped through holes radiating outward from the middle thereof.

[0031] The advantage is that the strip-shaped through hole is provided to facilitate deformation of the second connecting part.

[0032] In an optional embodiment, a second clamping portion abutting against the penetration portion is defined between adjacent through holes, and the second clamping portion is driven to deform to change the width of the through hole.

[0033] The advantage is that the penetration portion will synchronously drive the second clamping portion to deform and change the width of the through hole during the penetration operation, so that the user does not need to manually control the width of the through hole, and it can be completed in one operation, providing a better user experience.

[0034] In an optional embodiment, the second clamping portion and the second connecting portion are integrally formed.

[0035] The advantage is that the assembly steps are reduced, only one set of molds is needed to produce the second connecting part, and the production cost is reduced.

[0036] In an optional embodiment, the second connecting portion has a bulging tendency along the penetration direction of the penetration portion.

[0037] The advantage is that when the second connecting part cooperates with the brush body, the brush body will be close to the surface of the second connecting part, so that the brush body can also bulge to form an umbrella-like structure. When the brush body contacts the toilet surface, the surrounding side of the brush body will first contact the toilet surface for cleaning due to gravity, and at the same time, the first connecting part can also be hidden.

[0038] In an optional embodiment, the connecting hole is provided at the highest point of the protrusion of the second connecting portion.

[0039] The advantage is that the first connecting part can compress the brush body into an umbrella structure to more conveniently clean the toilet.

[0040] In an optional embodiment, the penetration portion and the connecting hole are interference fit.

[0041] The advantage is that the interference fit between the two makes it difficult for the penetration portion to escape from the connecting hole, thereby improving the reliability of fixing the connecting portion to the brush body.

[0042] In an optional embodiment, when the penetration portion is driven to be inserted into the connecting hole, the connecting hole is driven to open, and / or the penetration portion is driven to be compressed, so that the penetration portion passes through the connecting hole.

[0043] The advantage is that the connecting hole is driven to open so that the connecting hole becomes larger, which makes it easier for the piercing part to pass through, and also makes it easier for the connecting hole to catch the piercing part when it rebounds. The piercing part is driven to be compressed so that the piercing part becomes smaller, which makes it easier to insert into the connecting hole and pass through, and also makes it easier for the piercing part to stretch and get stuck in the connecting hole when it rebounds to prevent the piercing part from falling out.

[0044] In an optional embodiment, the penetration portion is driven to pass through the brush body along a first direction, and the second connecting portion moves toward the penetration portion along a second direction that forms an angle with the first direction, so that the second connecting portion is clamped between the limiting portion and the brush body.

[0045] The advantage is that the assembly steps are clearer and the assembly is convenient; when the second connecting part moves in a direction opposite to the second direction, the limiting function of the second connecting part on the brush body can be disassembled, which facilitates the replacement of parts.

[0046] In an optional embodiment, the brush body includes a puncture hole, and the puncture portion passes through the puncture hole and is connected to the second connecting portion.

[0047] The advantage is that the puncture hole facilitates the penetration of the piercing portion through the brush body, while also preventing the brush body from slipping out from between the first connecting portion and the second connecting portion, and the connection of the brush body is more firm and reliable.

[0048] In an optional embodiment, the brush body is made of a porous, water-absorbent, flexible material.

[0049] The advantage is that the brush body can absorb water and rub against the surface of the toilet for cleaning, and the flexible material can avoid scratching the surface of the toilet.

[0050] In an optional embodiment, the second connection portion is raised along the penetration direction of the penetration portion, so that the brush body is clamped between the first connection portion and the second connection portion with a raised tendency along the penetration direction of the penetration portion.

[0051] The advantage is that the brush body is raised to form an umbrella-like structure for cleaning, so that the first connecting part is hidden at the tip of the raised structure, thereby preventing the first connecting part from scratching the toilet surface when moving relative to the toilet surface.

[0052] In an optional implementation, the limiting portion is deformed by its own elastic force to limit the separation of the penetration portion and the second connecting portion.

[0053] The advantage is that when the limiting part is deformed by its own elastic force, the user does not need to manually drive the deformation, the assembly method is simple and more efficient, the limiting part can be stretched and stuck at the second connecting part, and it can also prevent the limiting part from falling out, thereby preventing the penetration part from falling out.

[0054] In a second aspect, the utility model relates to a toilet brush, comprising a toilet brush head and a handle, wherein the penetration portion is driven to sequentially penetrate the brush body and the second connection portion and be connected to the handle, and the brush body is clamped between the first connection portion and the second connection portion.

[0055] The advantage is that a handle is provided and the toilet brush head is connected to the handle. When cleaning the toilet, the toilet brush head is kept at a certain distance from the user's hands, avoiding dirtying the user's hands and providing a better user experience.

[0068] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0069] The utility model relates to a toilet brush head, which comprises a brush body 20, a first connecting part 30 and a second connecting part 40. A penetrating part 31 is arranged on one side of the first connecting part 30, and a limiting part 311 is arranged on the penetrating part 31. The penetrating part 31 is driven to pass through the brush body 20 and cooperate with the second connecting part 40 for connection, so that the brush body 20 is clamped between the first connecting part 30 and the second connecting part 40, and the limiting part 311 is limited on the side of the second connecting part 40 far away from the brush body 20 to limit the separation of the penetrating part 31 from the second connecting part 40.

[0070] Wherein, the brush body 20 is used for contacting the surface of the toilet and cleaning the surface of the toilet. In this example, the preferred brush body 20 is a flexible material with porous water absorption, such as sponge. Of course, the brush body 20 can also be other materials that can clean the toilet by friction.

[0071] Wherein, the first connecting part 30 and the second connecting part 40 cooperate to fix the brush body 20 between the two. Specifically, one side part of the first connecting part 30 has a penetrating part 31, and the penetrating part 31 passes through the brush body 20 and is connected with the second connecting part 40, so that the brush body 20 is clamped between the first connecting part 30 and the second connecting part 40. In this example, the preferred first connecting part 30 is in an "丄" shape, so as to facilitate the insertion of the penetrating part 31 into the brush body 20, so that the side part of the first connecting part 30 with the penetrating part 31 is close to the brush body 20. When the second connecting part 40 is connected with the penetrating part 31 in cooperation, the second connecting part 40 is close to the other side surface of the brush body 20, so that the brush body 20 is fixed between the first connecting part 30 and the second connecting part 40. When installing the brush body 20, only need to pass the penetrating part 31 of the first connecting part 30 through one side of the brush body 20, and cooperate with the penetrating part 31 on the other side of the brush body 20 through the second connecting part 40 to clamp the penetrating part 31. The assembly method is simple. At the same time, through the connection method of clamping the brush body 20 between the first connecting part 30 and the second connecting part 40, both opposite surfaces of the brush body 20 are fixed, and the installation is more firm and reliable, which can effectively avoid the separation or damage of the brush body 20 during the cleaning operation, and is not affected by environmental factors, and the user experience is better.

[0072] It can be understood that the penetrating part 31 may not be inserted into the brush body 20. The penetrating part 31 is close to the side wall of the brush body 20, and the brush body 20 is fixed by clamping the upper and lower surfaces of the brush body 20 through the first connecting part 30 and the second connecting part 40.

[0073] It can be understood that a plurality of brush bodies 20 are arranged in a ring around the penetrating part 31, and the brush bodies 20 are fixed by clamping the upper and lower surfaces of the brush bodies 20 through the first connecting part 30 and the second connecting part 40.

[0074] The piercing portion 31 includes a limiting portion 311 for limiting the separation of the first connecting portion 30 and the second connecting portion 40. The limiting portion 311 is limited on a side of the second connecting portion 40 away from the brush body 20 to limit the detachment of the piercing portion 31 and the second connecting portion 40. The projection of the limiting portion 311 in the direction of the second connecting portion 40 preferably overlaps with a part of the second connecting portion 40, so that when the limiting portion 311 moves relative to the second connecting portion 40 as the piercing portion 31 moves, the second connecting portion 40 can abut against and clamp the limiting portion 311 to prevent the limiting portion 311 from falling out. The second connecting portion 40 preferably in this example is provided with a connecting hole 41 for the piercing portion 31 to penetrate. When the connecting hole 41 is circular, the diameter of the connecting hole 41 is smaller than the minimum width of the limiting portion 311. When the connecting hole 41 is a non-standard shape, the minimum width of the connecting hole 41 is smaller than the minimum width of the limiting portion 311. It can be understood that when the second connecting portion 40 is provided with When there is a connecting groove for the penetration portion 31 to pass through, the width of the connecting groove is smaller than the minimum width of the limiting portion 311. In this example, the penetration portion 31 is a columnar structure, and the limiting portion 311 is arranged in its columnar part. The width of the limiting portion 311 is greater than the diameter of the columnar part. The projection of the limiting portion 311 toward the second connecting portion 40 overlaps with a part of the second connecting portion 40, so that when the penetration portion 31 moves toward the second connecting portion 40, the overlapping part between the limiting portion 311 and the second connecting portion 40 will clamp the limiting portion 311 to prevent the limiting portion 311 from escaping from the second connecting portion 40. In this example, the limiting portion 311 is preferably circular, so that when the penetration portion 31 is rotated at any angle, the penetration portion 31 will not come out of the second connecting portion 40, thereby enhancing the reliability of the installation of the brush body 20. Of course, the limiting portion 311 can also be other planar polygonal shapes, as long as the limiting portion 311 cannot come out of the second connecting portion 40.

[0075] Among them, when the penetration portion 31 passes through the brush body 20 and is connected with the second connecting portion 40, in this example, it is preferred that the second connecting portion 40 is deformed and clamped to the penetration portion 31 to limit the separation of the penetration portion 31 from the second connecting portion 40. Specifically, the second connecting portion 40 includes a connecting hole 41 whose size can be controlled by deformation. When the penetration portion 31 is driven to be inserted into the second connecting portion 40, the connecting hole 41 is driven to be squeezed and opened to facilitate the penetration of the penetration portion 31. When the penetration portion 31 passes through the connecting hole 41, the squeezing force on the connecting hole 41 disappears, so that the connecting hole 41 is reset and contracted, thereby clamping the penetration portion 31. The second connecting portion 40 is deformed and clamped to clamp the penetration portion 31, so that the fixing method of the two is more firm and reliable, and the assembly method is simpler.

[0076] It can be understood that a first clamping member is provided on the penetration portion 31, and a second clamping member is provided on the second connecting member (not shown in the figure). As the penetration portion 31 passes through the second connecting member, the second clamping member opens and engages with the first clamping member, thereby fixing the penetration portion 31 and the second connecting member. This example does not limit the shapes of the first clamping member and the second clamping member.

[0077] It can be understood that the penetration portion 31 can be clamped with the second connecting portion 40 by deformation (not shown in the figure). For example, a deformable limiting structure is provided on the penetration portion 31. When the penetration portion 31 is driven to pass through the second connecting portion 40, the limiting structure is driven to shrink to a smaller volume to facilitate the penetration portion 31 to pass through the second connecting portion 40. After the penetration portion 31 passes through the second connecting portion 40, the limiting structure is no longer driven to extend to a width exceeding the channel in the second connecting portion 40 for the penetration portion 31 to pass through, thereby limiting the penetration portion 31 from being separated from the second connecting portion 40.

[0078] It is understandable that the limiting portion 311 can be clamped with the second connecting portion 40 by deformation (not shown in the figure). For example, a plurality of slits are provided around the limiting portion 311. When the penetrating portion 31 is driven to pass through the second connecting portion 40, the limiting portion 311 is driven to shrink along the slits to facilitate the penetrating portion 31 to pass through the second connecting portion 40. When the penetrating portion 31 passes through the second connecting portion 40, the limiting portion 311 extends to a width exceeding the width of the channel in the second connecting portion 40 for the penetrating portion 31 to pass through, thereby limiting the penetrating portion 31 from being separated from the second connecting portion 40.

[0079] Among them, the second connection part 40 shrinks due to its own elastic force, and / or the penetration part 31 stretches due to its own elastic force to limit the separation of the penetration part 31 and the second connection part 40. Specifically, when the driving force of the second connection part 40 and the penetration part 31 is removed, they can be deformed by their own elastic force, and the user does not need to manually drive the deformation. The assembly method is simple and more efficient. The contraction of the second connection part 40 can clamp the penetration part 31 to prevent the penetration part 31 from falling out. The extension of the penetration part 31 can be stuck at the second connection part 40, which can also prevent the penetration part 31 from falling out. In this example, the elastic force of the preferred second connection part 40 and the penetration part 31 is determined by the material properties of the second connection part 40 and the penetration part 31. For example, the second connection part 40 and the penetration part 31 are both made of plastic. Of course, the second connection part 40 and the penetration part 31 can also be made of metal with a certain elasticity.

[0080] Among them, the first connecting portion 30 includes a connecting substrate 312, and a limiting portion 311 is provided on one side of the connecting substrate 312, such that the brush body 20 is clamped between the connecting substrate 312 and the limiting portion 311. Specifically, in this example, the connecting substrate 312 is preferably circular in structure. The shape of the connecting member is not limited in this example. A penetrating portion 31 is provided on one side of the connecting substrate 312, and the two are arranged in an "丄" shape. The limiting portion 311 is provided on the side of the connecting substrate 312 where the penetrating portion 31 is located, such that the connecting substrate 312, the penetrating portion 31, and the limiting portion 311 are arranged in a "土" shape. The connecting substrate 312 can limit the brush body 20 by abutting against one side surface of the brush body 20.

[0081] Among them, the second connecting portion 40 is provided between the connecting substrate 312 and the limiting portion 311 so that the brush body 20 is clamped between the connecting substrate 312 and the second connecting portion 40. Since the limiting portion 311 needs to pass through the brush body 20, when only the limiting portion 311 is used to limit in the penetrating direction of the penetrating portion 31, the limiting effect is poor and it is easy to fail. Therefore, the second connecting portion 40 is provided, which can effectively limit the brush body 20 in the penetrating direction of the penetrating portion 31, thereby improving the firmness of the installation of the brush body 20. When the second connecting portion 40 is connected to the penetrating portion 31, the second connecting portion 40 is provided between the limiting portion 311 and the connecting substrate 312, such that the limiting portion 311 can play a certain limiting role on the second connecting portion 40, just making the second connecting portion 40 and the connecting substrate 312 fix the brush body 20.

[0082] Among them, the maximum width of the connecting substrate 312 is smaller than the minimum width of the second connecting portion 40. When the connecting substrate 312 and the second connecting portion 40 are circular, the diameter of the connecting substrate 312 is smaller than the diameter of the second connecting portion 40, such that the shape of the second connecting portion 40 is larger than the shape of the connecting substrate 312. When the connecting substrate 312 and the second connecting portion 40 clamp the brush body 20, the contact area between the second connecting portion 40 with a larger shape and the brush body 20 is larger. When the connecting substrate 312 with a smaller shape presses the brush body 20, the circumferential side of the brush body 20 will have a tendency to bulge towards the direction of the connecting substrate 312, that is, the brush body 20 has a tendency to bulge along the penetrating direction of the penetrating portion 31, thereby preventing the brush body 20 from having an upward warping tendency when being fixed and affecting the cleaning operation of the toilet. It can be understood that when the connecting substrate 312 and the second connecting portion 40 are non-standard shapes, the maximum width of the connecting substrate 312 is smaller than the minimum width of the second connecting portion 40, so that the shape of the second connecting portion 40 is larger than the shape of the connecting substrate 312.

[0083] Among them, the distance between the connecting substrate 312 and the limiting part 311 is defined as H, the thickness of the second connecting part 40 is defined as A, and the thickness of the brush body 20 is defined as B, wherein HA≤B. Specifically, when the distance between the second connecting part 40 and the connecting substrate 312 is less than the thickness of the brush body 20, the brush body 20 will produce a certain deformation when being fixed, so as to prevent a gap between the brush body 20 and the second connecting part 40 and the connecting substrate 312, and effectively prevent the brush body 20 from loosening when being fixed. Since the brush body 20 has a certain elasticity, the preferred HA in this example is ≤1 / 2B, so that the connecting substrate 312 and the second connecting part 40 can effectively clamp the brush body 20, and further compress the gap between the brush body 20 and the second connecting part 40 and the connecting substrate 312. At the same time, since the shape of the connecting substrate 312 is relatively small, the brush body 20 will form a bulge in the penetration direction of the penetration part 31.

[0084] Among them, the second connecting part 40 has a bulging tendency along the insertion direction of the penetration part 31, so that the brush body 20 forms an umbrella-shaped structure. When the first connecting part 30 applies force to the brush body 20 to squeeze the brush body 20, the brush body 20 will form a bulging tendency along the insertion direction of the penetration part 31 and be clamped between the first connecting part 30 and the second connecting part 40. The brush body 20 will form a bulging tendency to clean the toilet. The part of the brush body 20 connected to the first connecting part 30 will bulge upward, and the part of the brush body 20 not connected to the first connecting part 30 will be set downward, so that the first connecting part 30 can be hidden at the highest point of the bulge of the brush body 20, thereby preventing the first connecting part 30 from scratching the toilet surface when it moves relative to the toilet surface.

[0085] Among them, the penetration portion 31 includes a connecting head 313, and the second connecting portion 40 includes a connecting hole 41. The connecting head 313 passes through the connecting hole 41 to connect with the handheld component so that the brush body 20 is installed in the handheld component. Specifically, the connecting head 313 is used to connect with the handheld component, so one end of the handheld component is provided with a matching hole matching the connecting head 313, so that the distance between the toilet brush head and the user's hand can be extended when cleaning the toilet to avoid dirty hands, and the user has a better experience when using it. The connecting hole 41 cooperates with the connecting head 313 to facilitate the fixing of the connecting head 313 to the second connecting portion 40. This example does not limit the shape of the connecting hole 41, as long as it can allow the connecting head 313 to pass through and limit the detachment of the connecting head 313. The preferred connecting head 313 in this example is spherical, so that when the toilet brush head is connected to the handheld component, the toilet brush head can be universally rotated to adapt to different usage operations. It can be understood that the connecting head 313 can also be set to a shape with a curved surface on the top, such as a hemispherical shape, as long as the connecting head 313 and the handheld component can be universally rotated.

[0086] Among them, the connector 313 is provided with a plurality of vertical edges 3131 arranged in the vertical direction, and the shapes of the connecting hole 41 and the vertical edges 3131 match, so that when the connector 313 is inserted into the connecting hole 41, the vertical edges 3131 slide in the connecting hole 41. Specifically, the preferred connector 313 of this example includes a connecting column, and a plurality of vertical edges 3131 are arranged around the side wall of the connecting column. The vertical edges 3131 are fan-shaped structures, and the side of the vertical edges 3131 with arc edges is arranged away from the connecting column, so that the plurality of vertical edges 3131 form a spherical connector 313 around the connecting column, and an avoidance space is formed between two adjacent vertical edges 3131. When the connector 313 passes through the connecting hole 41, since the vertical edges 3131 have a certain width, the part of the connecting hole 41 corresponding to the vertical edges 3131 is deformed. The amount is larger, and the deformation of the part of the connecting hole 41 corresponding to the avoidance space is smaller. When the shape of the connecting hole 41 matches the shape of the vertical edge 3131, that is, a strip through hole 43 is formed in the part of the connecting hole 41 corresponding to the vertical edge 3131, and the length of the strip through hole 43 is greater than the width of the vertical edge 3131. The deformation of the part of the connecting hole 41 corresponding to the vertical edge 3131 is reduced. Therefore, in general, the vertical edge 3131 is set to reduce the deformation of the connecting hole 41, so that the connecting head 313 is easier to pass through the connecting hole 41, and the user experience is better.

[0087] Among them, a connecting hole 41 is provided in the middle of the second connecting part 40, which is suitable for the penetration part 31 to pass through the connecting hole 41 and shrink through the connecting hole 41 to limit the penetration part 31 from escaping from the connecting hole 41. Specifically, the shape of the preferred connecting hole 41 in this example matches the shape of the connecting head 313, so that the penetration part 31 can pass through the connecting hole 41 smoothly. The connection hole 41 is arranged to cooperate with the penetration part 31, which makes installation more convenient. It only needs the second connecting part 40 to fit tightly with the brush body 20 so that the penetration part 31 passes through the brush body 20 and the connecting hole 41 at the same time, so that the brush body 20 can be clamped between the first connecting part 30 and the second connecting part 40, and the installation method is simpler. It can be understood that the shape of the connecting hole 41 can be circular or even other regular shapes, but the connecting hole 41 has elasticity at least on its circumference, so that the connecting hole 41 can be driven to enlarge or reduce the aperture.

[0088] Among them, the connecting hole 41 includes a plurality of strip-shaped through holes 43 radiating outward from the middle thereof. Specifically, in this example, the number and shape of the through holes 43 preferably match the shape and number of the vertical edges 3131, so that when the connecting head 313 passes through the connecting hole 41, the vertical edges 3131 cooperate with the through holes 43 and can move along the through holes 43. In this example, the through holes 43 are preferably arranged in the middle of the second connecting part 40 and are distributed radially, that is, one ends of multiple through holes 43 are connected together.

[0089] Among them, a second clamping portion 42 abutting against the penetration portion 31 is defined between adjacent through holes 43, and the second clamping portion 42 is driven to deform to change the width of the through hole 43. Specifically, the preferred second clamping portion 42 in this example is a triangular structure, and the tip of the second clamping portion 42 is arranged toward the direction close to the penetration portion 31, and the tips of multiple second clamping portions 42 are arranged together toward the direction close to the penetration portion 31, so that when the penetration portion 31 passes through the connecting hole 41, multiple second clamping portions 42 are arranged around the penetration portion 31. The tip of the second clamping portion 42 is relatively easy to deform. When the penetration portion 31 passes through the connecting hole 41, the connecting head 313 will squeeze the second clamping portion 42 to open in the penetration direction of the penetration portion 31 so that the connecting hole 41 becomes larger. When the connecting head 313 passes through the connecting hole 41, the squeezing force on the second clamping portion 42 disappears. At this time, the second clamping portion 42 will recover and shrink due to its own elastic force, so that the connecting head 313 cannot be detached from the connecting hole 41, thereby limiting the detachment of the first connecting portion 30 and the second connecting portion 40.

[0090] Among them, the second clamping part 42 and the second connecting part 40 are preferably integrally formed in this example, so that the second connecting part 40 as a whole can be produced by a set of molds, which reduces production costs and reduces assembly steps. At the same time, when the two are integrally formed, the second clamping part 42 has higher strength when driven to be extruded and deformed, is not easy to fall out of the second connecting part 40, and has higher assembly stability.

[0091] It can be understood that the second clamping portion 42 can be connected to the second connecting portion 40 via a rotating shaft, and the second clamping portion 42 can be reset by an elastic device such as a torsion spring.

[0092] Among them, the second connecting part 40 has a bulging tendency along the penetration direction of the penetration part 31, so that the brush body 20 forms an umbrella-shaped structure. When the brush body 20 contacts the toilet surface after absorbing water, the cleaning side of the brush body 20 will be heavier. Under the action of gravity, the surrounding side of the brush body 20 will first contact the toilet surface for cleaning, which can hide the first connecting part 30 and prevent the first connecting part 30 from scratching the toilet surface when it moves relative to the toilet surface.

[0093] Among them, the connecting hole 41 is arranged at the highest point of the second connecting part 40, so that the first connecting part 30 fixes the brush body 20 at the highest point of the second connecting part 40, specifically, the connecting substrate 312 applies pressure to the brush body 20 so that the brush body 20 is compressed into an umbrella structure, thereby better cleaning the toilet.

[0094] Among them, the penetration portion 31 and the connecting hole 41 are interference fit, so that the penetration portion 31 is not easy to fall out of the connecting hole 41. In this example, the size of the penetration portion 31 is preferably larger than the size of the connecting hole 41. When the connecting hole 41 is circular, the diameter of the connecting hole 41 is smaller than the minimum width of the cross section of the penetration portion 31 at the point where it cooperates with the connecting hole 41. When the connecting hole 41 is a non-standard shape, the minimum width of the connecting hole 41 is smaller than the minimum width of the cross section of the penetration portion 31 at the point where it cooperates with the connecting hole 41.

[0095] Among them, when the penetration portion 31 is driven to be inserted into the connecting hole 41, the connecting hole 41 is driven to open, and / or the penetration portion 31 is driven to be compressed so that the penetration portion 31 passes through the connecting hole 41. In the process of the penetration portion 31 being driven to be inserted into the connecting hole 41, the preferred connecting hole 41 in this example is driven to open so that the connecting hole 41 becomes larger, which is more convenient for the penetration portion 31 to pass through, and also facilitates the connecting hole 41 to get stuck with the penetration portion 31 when it rebounds. It can be understood that the penetration portion 31 is driven to be compressed so that the penetration portion 31 becomes smaller, which is more convenient to insert into and pass through the connecting hole 41, and also facilitates the penetration portion 31 to stretch and get stuck in the connecting hole 41 when it rebounds to prevent the penetration portion 31 from falling out. Preferably, the limiting portion 311 in the penetration portion 31 is deformed.

[0096] Among them, the penetration portion 31 is driven to pass through the brush body 20 along a first direction, and the second connecting portion 40 moves toward the penetration portion 31 along a second direction at an angle to the first direction, so that the second connecting portion 40 is clamped between the limiting portion 311 and the brush body 20. The assembly steps are clearer and easier to assemble. The preferred first direction in this example is perpendicular to the second direction, so that the second connecting portion 40 and the connecting substrate 312 remain roughly parallel, so that when the brush body 20 abuts against the second connecting portion 40, the brush body 20 can remain perpendicular to the penetration portion 31. When the penetration portion 31 is matched with the hand-held component, the brush body 20 is vertically arranged to the hand-held component. In this example, the preferred second connecting portion 40 is provided with an installation groove. When the installation groove of the second connecting portion 40 is inserted into the penetration portion 31 along a direction perpendicular to the penetration portion 31, the installation groove is clamped between the limiting portion 311 and the brush body 20. When the second connecting portion 40 moves in a direction opposite to the second direction, the second connecting portion 40 can be disassembled to limit the brush body 20, which is convenient for replacing parts.

[0097] It can be understood that a round hole is provided in the penetration portion 31 , and during the process of inserting the second connection portion 40 into the round hole, the middle portion of the second connection portion 40 is stuck in the round hole, so that the second connection portion 40 can limit the brush body 20 .

[0098] It can be understood that if the first direction and the second direction form an acute angle or an obtuse angle, the brush body 20 and the central axis of the handheld component are arranged at an acute angle or an obtuse angle, and the positioning and assembly of the second connecting portion 40 and the penetration portion 31 can also be achieved.

[0099] Among them, the preferred brush body 20 of this example includes a puncture hole 21, and the penetration part 31 passes through the puncture hole 21 and is connected to the second connecting part 40. The brush body 20 can be provided with the puncture hole 21 during the processing and production process. The puncture hole 21 facilitates the penetration part 31 to pass through the brush body 20. When the user drives the brush body 20 to move relative to the toilet for cleaning, due to the friction on the surface of the toilet, the brush body 20 will be subjected to a large friction during the cleaning process. When the penetration part 31 is not inserted into the puncture hole 21, the brush body 20 is easy to fall out when it is only clamped by the first connecting part 30 and the second connecting part 40, affecting the user experience. Therefore, the puncture hole 21 is provided for the penetration part 31 to be inserted to prevent the brush body 20 from being subjected to friction and sliding out from between the first connecting part 30 and the second connecting part 40, and the connection of the brush body 20 is more firm and reliable.

[0100] Among them, the preferred brush body 20 is a porous water-absorbing flexible material, such as a sponge. The sponge has strong water absorption and friction properties. When used as a wiping object in contact with the toilet, the cleaning efficiency is high. At the same time, the cost of the sponge is low and it is convenient to replace. The brush body 20 absorbs water and then rubs against the surface of the toilet for cleaning. The flexible material can avoid scratching the surface of the toilet. Of course, the brush body 20 can also be a water-absorbing flexible material such as PVC material. This example does not limit the shape of the brush body 20. The brush body 20 can be circular, quasi-circular, polygonal, etc., or the brush body 20 can be composed of bristles of a plurality of flexible materials, or it can be a combination of bristles and a brush body 20 of a fixed shape.

[0101] Secondly, the utility model relates to a toilet brush, including a toilet brush head and a handle 10. The penetration portion 31 is driven to pass through the brush body 20 and the second connection portion 40 in sequence and is connected to the handle 10. The brush body 20 is clamped between the first connection portion 30 and the second connection portion 40. The handle 10 is provided, and the toilet brush head is connected to the handle 10. When cleaning the toilet, the toilet brush head is kept at a certain distance from the user's hands to avoid dirtying the user's hands, and the user experience is better.

[0102] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
