Description

Technical Field

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

[0002] A cleaning brush is a cleaning tool used for scrubbing objects. It has a good cleaning effect and is frequently used in daily life. Existing cleaning brushes generally include a plastic handle and a brush head disposed at the front end of the handle, and the brush head is generally a bristle type. When in use, the bristles of the brush head can be operated by holding the handle to clean stains on the surface of the object, which is convenient for cleaning.

[0003] However, the existing cleaning brush still has a disadvantage that the existing brush head and the brush handle are of an integrated structure, so that the brush head cannot be replaced. Since the bristles of the brush head are easily damaged during the brushing process, when the bristles of the brush head are damaged, the cleaning brush cannot be used, so the entire cleaning brush needs to be scrapped, and the intact brush handle is wasted, which is not conducive to environmental protection.

[0004] In addition, due to the variety of brush heads, different types of brush heads are suitable for cleaning different items and for different stains. Common types of brush heads include bristles, brush cloths, etc. Users will reasonably choose cleaning brushes with different types of brush heads according to different items and stains. However, the brush heads of existing cleaning brushes cannot be replaced, resulting in that the cleaning brush can only be fixedly equipped with one type of brush head. In order to meet various needs, users need to purchase multiple cleaning brushes with different types of brush heads, which increases the purchase cost and is not conducive to storage. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a cleaning brush with a replaceable brush head.

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a cleaning brush, including a brush handle and a brush head connected to the brush handle, the front end of the above-mentioned brush handle is connected to a fixed seat, the brush head includes a brush seat and a brushing part arranged under the brush seat for brushing objects, a receiving groove is opened under the fixed seat, the brush seat is installed in the receiving groove and is buckled with the fixed seat, and the brushing part is located outside the receiving groove.

[0007] In the above scheme, a fixing seat is provided at the front end of the brush handle, and the brush seat of the brush head is installed in the receiving groove and engaged with the fixing seat, so as to realize the structural function of the brush head being detachable and replaceable. When the brush head is damaged, the user can release the engagement between the brush seat and the fixing seat, and remove the brush seat from the receiving groove, so as to complete the disassembly and separation of the brush head from the fixing seat, and then replace the new brush head and assemble it with the fixing seat of the brush handle. In this way, there is no need to scrap the entire cleaning brush, and the intact brush handle can be recycled, which is beneficial to environmental protection. In addition, the user can also replace the appropriate type of brush head and the fixing seat of the brush handle for assembly and use according to the items and stains to be cleaned. In this way, the user does not need to purchase multiple cleaning brushes with different types of brush heads, but only needs to purchase one brush handle and different types of brush heads to meet the cleaning requirements of different items and stains, saving the user's purchase cost and facilitating storage.

[0008] Furthermore, two elastic arms are arranged on the brush holder in a relative manner, and blocks are arranged on the outer sides of the two elastic arms, and buckle holes are opened at the positions of the corresponding elastic arms on the fixed seat. When the brush holder is installed in the receiving groove, the two elastic arms pass through the corresponding buckle holes respectively, and the blocks pass through the buckle holes and are located on the upper side of the fixed seat. At the same time, the elastic arms push the lower side of the blocks against the upper side of the fixed seat under the action of their own elastic force, so as to realize the buckle connection between the blocks and the fixed seat. At this time, under the action of the blocks against the fixed seat, the elastic arms and the brush holder cannot move downward, and under the action of the elastic force of the elastic arms, the blocks always keep against the upper side of the fixed seat, so as to ensure the assembly stability of the brush head and the fixed seat. When the brush head needs to be disassembled, the two elastic arms can be manually pushed inward to deform and drive the blocks to disengage from the upper side of the fixed seat, and then the two elastic arms are pressed downward to get out of the buckle holes, and the brush holder is pulled out of the receiving groove, so as to complete the removal of the brush head from the fixed seat.

[0009] Furthermore, the left and right sides of the brush holder are respectively provided with avoidance openings, and the two elastic arms are respectively arranged in the avoidance openings, and the inner sides of the elastic arms are separated from the opposite sides of the avoidance openings by a distance, so that sufficient space can be reserved for the elastic arms to deform inwards, making it more convenient and labor-saving for users to move the elastic arms to deform inwards, and the avoidance openings can prevent the elastic arms from excessively deforming inwards and breaking.

[0010] Furthermore, the fixing seat is provided with a notch at the outer wall position corresponding to the buckle hole. When the brush holder is installed in the receiving groove, the card block is inserted into the notch position and abuts against the upper side of the notch of the fixing seat. In this solution, after the notch is provided on the outer side of the fixing seat, the notch can reserve more space for the finger to move the elastic arm, so that the user can more conveniently move the elastic arm inward to deform, thereby driving the card block to disengage from the notch of the fixing seat, and making the brush head removal operation more convenient.

[0011] Furthermore, the upper side of the above-mentioned card block is an inclined structure. When the elastic arm is inserted into the accommodating groove to the position where the upper side of the card block abuts against the lower side of the fixing seat, the card block can be pushed upward with force. The upper inclined surface of the card block will slide along the lower side of the fixing seat and force the elastic arm to deform inward, so that the card block will not be blocked by the lower side of the fixing seat, which facilitates the assembly operation of the brush head and the fixing seat. The lower side of the above-mentioned card block is a flat structure, which can make the lower side of the card block abut against the upper side of the notch of the fixing seat more stable.

[0012] Furthermore, two positioning protrusions are arranged opposite to each other on the left and right sides of the brush holder, and the two positioning protrusions are separated to form a gap. A plurality of positioning protrusions are arranged at the bottom of the accommodating groove, and the plurality of positioning protrusions intersect vertically and horizontally to form a first limiting groove and a second limiting groove. The first limiting groove and the second limiting groove are separated by a positioning protrusion. When the brush holder is installed in the accommodating groove, the bottom of the positioning protrusion abuts against the top of the brush holder to prevent the brush holder from moving upward, and the two positioning protrusions are respectively placed in the first limiting groove and the second limiting groove, and a positioning protrusion between the first limiting groove and the second limiting groove is located in the gap between the two positioning protrusions to prevent the brush holder from moving left and right and front and back. This can better ensure the assembly stability of the brush holder and the fixed holder.

[0013] Furthermore, a scraper is provided in front of the fixing seat. When the surface of the object is stained with stains that are difficult to remove by the scrubbing part, the user can use the scraper to remove them. The multiple functions can further meet the user's cleaning needs for different stains.

[0014] Furthermore, a pressing handle is provided on the above-mentioned brush handle. During the cleaning operation, when encountering stains that are difficult to clean, the user can hold the brush handle with one hand and hold the pressing handle with the other hand to press down the brush handle and the brush head. In this way, the user can exert better force to scrub the stains, making cleaning more convenient.

[0015] Furthermore, the above-mentioned brushing part is a brush bristle or a brush block arranged under the brush seat, and the user can freely choose the type of the brushing part according to the objects to be cleaned and the types of stains.

[0016] Furthermore, a plurality of finger grooves are provided on the lower side of the tail of the brush handle, and thumb ridges are provided on the upper side of the brush handle, so that the user can hold the brush handle more firmly and more comfortably.

[0017] The beneficial effects of the cleaning brush of the utility model are as follows: 1. The brush head can be replaced at will.

[0030] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] Embodiment 1

[0032] like Figure 1 , 2 As shown in Figures 3 and 4, the present embodiment provides a cleaning brush, including a brush handle 1 and a brush head 2 connected to the brush handle 1. The front end of the brush handle 1 is connected to a fixed seat 11. The brush head 2 includes a brush seat 21 and a brushing portion 22 provided under the brush seat 21 for brushing objects. A receiving groove 111 is provided under the fixed seat 11. The brush seat 21 is mounted in the receiving groove 111 and is buckled with the fixed seat 11. The brushing portion 22 is located outside the receiving groove 111.

[0033] The cleaning brush of this embodiment is provided with a fixing seat 11 at the front end of the brush handle 1, and then the brush seat 21 of the brush head 2 is buckled with the fixing seat 11 of the brush handle 1, so as to realize the structural function that the brush head 2 can be detached and replaced. In this way, when the brush head is damaged, the user can replace a new brush head 2 and assemble it with the fixing seat 11 of the brush handle 1, so that the entire cleaning brush does not need to be scrapped, and the intact brush handle 1 can be recycled, which is beneficial to environmental protection.

[0034] In addition, the user can also reasonably select the brush head 2 of different types of brushing parts 22 according to the items and stains to be cleaned, for example, Figure 1 As shown, the brushing part 22 of the brush head 2 is a bristle disposed under the brush holder 21, or, as shown in Figure 4 As shown, the brushing part 22 of the brush head 2 is a brush block arranged under the brush holder 21, and the outer side of the brush block is Kevlar cloth; and the brush head 2 with bristles or brush blocks can be freely replaced by the user according to the items and stain types to be cleaned, and the operation is more flexible. In this way, the user does not need to buy multiple cleaning brushes with different types of brush heads, but only needs to buy a brush handle 1 and different types of brush heads 2 to meet the cleaning requirements of different items and stains, saving the user's purchase cost and facilitating storage.

[0035] When the cleaning brush of this embodiment needs to install the brush head 2, the brush holder 21 can be buckled with the fixing seat 11 in the installation groove 111 to complete the installation operation of the brush head 2. At this time, the outer side of the brush holder 21 abuts against the inner side of the groove 111, which can prevent the brush holder 21 from shaking in the groove 111, and the brush holder 21 will not be separated from the groove 111 under the buckling effect of the fixing seat 11, so as to ensure the installation stability of the brush head 2, so that the user can use the cleaning brush to wash objects more conveniently and reliably. When the brush head 2 needs to be disassembled, the brush holder 21 can be released from the fixing seat 11, and then the brush holder 21 can be removed from the groove 111 to complete the disassembly operation of the brush head 2. The disassembly and assembly operation is convenient and fast.

[0036] Embodiment 2

[0037] This embodiment is a further improvement on the structure of the cleaning brush of the first embodiment. The improvement is as follows: Figure 2 , 5 As shown in , 6, the brush holder 21 is provided with two elastic arms 211 opposite to each other, and blocks 2111 are respectively provided on the outer sides of the two elastic arms 211. The fixing seat 11 is provided with buckle holes 112 at the positions corresponding to the elastic arms 211, and the buckle holes 112 are communicated with the accommodating groove 111. When the brush holder 21 is installed in the accommodating groove 111, the two elastic arms 211 respectively pass through the corresponding buckle holes 112. At this time, the block 2111 passes through the buckle holes 112 and is located on the upper side of the fixing seat 11. At the same time, the elastic arm 211 pushes the lower side of the block 2111 to abut against the upper side of the fixing seat 11 through its own elastic force, thereby realizing the buckling connection between the block 2111 and the fixing seat 11.

[0038] like Figure 2 As shown, the middle positions of the left and right sides of the brush holder 21 are respectively provided with avoidance openings 210, and the two elastic arms 211 are respectively arranged in the corresponding positions of the avoidance openings 210, and the inner sides of the elastic arms 211 are separated from the opposite sides of the avoidance openings 210 by a distance, so that sufficient space can be reserved for the elastic arms 211 to deform inwardly, making it more convenient and labor-saving for the user to move the elastic arms 211 to deform inwardly, and the inner side of the avoidance openings 210 can prevent the elastic arms 211 from excessively deforming inwardly and breaking.

[0039] like Figure 1 , 2 As shown, the fixing seat 11 is provided with a notch 113 at the outer wall position corresponding to the buckle hole 112. When the brush seat 21 is installed in the receiving groove 111, the clamping block 2111 is clamped into the notch 113 and abuts against the upper side of the notch 113 of the fixing seat 11. In this solution, after the notch 113 is provided on the outer side of the fixing seat 11, the notch 113 can reserve more space for fingers to move the elastic arm 211, so that the user can more conveniently move the elastic arm 211 to deform inwardly, thereby driving the clamping block 2111 to disengage from the notch 113 of the fixing seat 11, and the disassembly operation of the brush head 2 is more convenient.

When the elastic arm 211 is inserted into the receiving groove 111 to the position where the upper side of the block 2111 abuts against the lower side of the fixing seat 11, the block 2111 can be pushed upward with force. The upper inclined surface of the block 2111 will slide along the lower side of the fixing seat 11 and force the elastic arm 211 to deform inward, so that the block 2111 will not be blocked by the lower side of the fixing seat 11, which facilitates the assembly operation of the brush head 2 and the fixing seat 11. The lower side of the block 2111 is a flat structure, which can make the lower side of the block 2111 abut against the upper side of the notch 113 of the fixing seat 11 more stable.

[0041] When the cleaning brush of this embodiment is used, when the brush head 2 needs to be installed, the brush holder 21 can be inserted into the receiving groove 111, and the two elastic arms 211 are respectively passed upward through the corresponding buckle holes 112, and the lower side of the clamping block 2111 is abutted against the upper side of the notch 113 of the fixing seat 11, so that the installation operation of the brush head 2 can be completed. At this time, under the abutment effect of the clamping block 2111 and the notch 113 of the fixing seat 11, the elastic arm 211 and the brush holder 21 cannot move downward, and under the elastic force of the elastic arm 211, the clamping block 2111 always remains against the upper side of the notch 113, thereby ensuring the assembly stability of the brush head 2. When the brush head 2 needs to be disassembled, the two elastic arms 211 can be manually pushed inward to deform and drive the block 2111 to disengage from the upper side of the notch 113 of the fixing seat 11, and then the two elastic arms 211 are pressed downward to disengage from the buckle hole 112, so that the brush seat 21 is disengaged from the accommodating groove 111, and the disassembly operation of the brush head 2 is completed.

[0042] Embodiment 3

[0043] This embodiment is a further improvement on the structure of the cleaning brush of the second embodiment. The improvement is as follows: Figure 2 , 36, the brush holder 21 is provided with two positioning protrusions 212 on the left and right sides, the two positioning protrusions 212 are separated to form a gap, the bottom of the receiving groove 111 is provided with a plurality of positioning protrusions 114, the plurality of positioning protrusions 114 intersect vertically and horizontally to form a first limiting groove 1141 and a second limiting groove 1142, the first limiting groove 1141 and the second limiting groove 1142 are separated by a positioning protrusion 114, when the brush holder 21 is installed in the receiving groove 111, There is a positioning convex strip 114 at the bottom that abuts against the top of the brush holder 21 to prevent the brush holder 21 from moving upward, and the two positioning protrusions 212 are respectively placed in the first limiting groove 1141 and the second limiting groove 1142, and a positioning convex strip 114 between the first limiting groove 1141 and the second limiting groove 1142 is located in the gap between the two positioning protrusions 212 to prevent the brush holder 21 from moving left and right and front and back. This can better ensure the assembly stability of the brush holder 21 and the fixing seat 11.

[0044] like Figure 1 As shown, a scraper 115 is provided in front of the fixing seat 11. When in use, when the surface of the cleaned object is stained with stains that are difficult to remove by bristles or a brush block, the user can use the scraper 115 to remove them. The multiple functions can further meet the user's cleaning needs for different stains.

[0045] The brush handle 1 is provided with a pressing handle 12. During the cleaning operation, when encountering stains that are difficult to clean, the user can hold the brush handle 1 with one hand and hold the pressing handle 12 with the other hand to press down the brush handle 1 and the brush head 2, so that the user can exert better force to scrub the stains, making cleaning more convenient.
