Description

TECHNICAL FIELD

[0001] The utility model relates to cleaning tool technical field, especially a toilet brush and system of replaceable brush head. BACKGROUND

[0002] As a special cleaning tool, toilet brush is mainly used for cleaning the inner wall of the toilet and its surrounding area. Due to its simple and practical design and efficient cleaning ability, it has become one of the essential daily cleaning supplies in households, hotels, public toilets and other places. Based on the traditional toilet brush, with the increasing demand of consumers for hygiene, safety and convenience, the market has gradually introduced various upgraded designs, such as disposable toilet brushes and toilet brushes with replaceable brush heads. Among them, disposable toilet brushes are equipped with disposable brush heads, which do not need to be washed before replacement, significantly improving hygiene and convenience, and are widely favored by users.

[0003] Under this background, patent CN213821201U provides a toilet brush with replaceable brush head, which is characterized by a locking member and a clamping part that can switch between clamping and active states through elastic deformation, completing the fixation and replacement of the brush head. At the same time, the design uses the elastic spring between the elastic return element and the fixing element to provide stable connection and reset function by using the characteristics of spring extension and contraction. This structure relies on the elastic force of the elastic spring to firmly clamp the brush head on the handle, thereby ensuring that the brush head does not come off during cleaning, while allowing the user to quickly release the locking member when replacing the brush head.

[0004] However, since the toilet brush is usually used in a high-humidity and high-corrosion bathroom environment, the spring as a key elastic component is prone to rust due to moisture and cleaner corrosion. Over time, rust will gradually weaken the elasticity of the spring and even cause it to fail completely, eventually making the handle push rod unable to reset normally. In this case, the user may face difficulties in operation when cleaning or replacing the brush head, and even cause the entire toilet brush to lose its function. Although this design helps to stabilize the connection of the brush head, it has certain limitations in terms of long-term reliability and durability. SUMMARY

[0005] Therefore, it is necessary to provide a toilet brush with replaceable brush head that can clamp and release the brush head without the need for a spring or other elastic element to drive, based on the problem of existing technology using elastic element reset, which affects the use of the handle after the elastic element fails.

[0050] Referring to Figures 1 to 3 The utility model discloses an embodiment provides a replaceable brush head's closestool brush, including brush handle 100 and the brush head 200 of setting in brush handle 100 one end, brush handle 100 includes handle cover 110 and sets up the connecting mechanism 120 in handle cover 110, and the brush head 200 includes the joint 210 for connecting brush handle 100, handle cover 110 has the accommodation cavity, is equipped with the sliding slot in the accommodation cavity, and the side of the accommodation cavity close to the brush head 200 is also equipped with fixed hole 111, and the connecting mechanism 120 includes the push rod 121, connecting rod 122 and chuck 123 of interconnection, and the push rod 121 sets up in the sliding slot, and the sliding pair is formed with the sliding slot, and the chuck 123 is rotatably connected with fixed hole 111, and the side of the accommodation cavity towards the brush head 200 is also equipped with the connecting hole 112 suitable for the joint 210 insertion, and the joint 210 includes neck 211 and end 212, and the cross-sectional area of neck 211 is less than the cross-sectional area of end 212, and the chuck 123 has chucking cavity, and the wall surface on chucking cavity is equipped with the through slot for accommodating neck 211.

[0051] Under the action of external force, the push rod 121 moves along the axial direction of the sliding slot, drives the chuck 123 to rotate around the axis of the fixed hole 111 through the connecting rod 122, so as to switch the chuck 123 between the first position and the second position. When the chuck 123 rotates along the axis of the fixed hole 111 to the first position, the opening of the chucking cavity faces the connecting hole 112 to accommodate or disengage the end 212. After the end 212 extends into the chucking cavity, the push rod 121 drives the chuck 123 to rotate to the second position to make the opening of the chucking cavity face the accommodation cavity. At this time, the neck 211 is embedded in the through slot.

[0052] In the embodiment, the accommodating cavity provides installation and movement space for the connecting mechanism 120, and the sliding groove limits the movement direction of the push rod 121, so that the push rod 121 stably slides in the axial direction, thereby improving the operation precision and stability. The fixing hole 111 provides a rotation fulcrum for the chuck 123, so that the chuck 123 can stably rotate around the axis of the fixing hole 111. Through the combined design of the sliding pair and the rotation pair, the mechanical transmission chain that the push rod 121 drives the connecting rod 122 and the connecting rod 122 drives the chuck 123 to rotate is realized, the reliability of mechanical movement is improved, the cumbersome steps of directly operating the chuck 123 are avoided, and the user operation is more convenient. Through rotation of the push rod 121, the connecting rod 122 and the chuck 123, the rotation angle of the chuck 123 is directly controlled by sliding of the push rod 121, so that stable switching from the first position to the second position is realized. The transmission of the mechanism is simple and reliable, and the force transmission path is clear and definite. The connecting hole 112 provides a butt joint interface of the connector 210 and the brush handle 100, so that the installation and positioning are accurate.

[0053] The toilet brush provided in the embodiment is characterized in that the chuck 123 is a semispherical bowl structure, which is matched with the shape of the end portion 212 of the connector 210, and a through groove is formed in the chuck 123 and used for clamping the neck portion 211 of the connector 210. In this way, when the chuck 123 is rotated to the second position, only the through groove faces the brush handle 100, the neck portion 211 passes through the through groove, and the end portion 212 is accommodated in the chuck 123, that is, in the accommodating cavity of the brush handle 100. Since the cross-sectional area of the end portion 212 is larger than that of the neck portion 211, the end portion 212 will not fall off from the chuck 123, and the chuck 123 clamps the connector 210. Since the clamping process only involves rotation of the chuck 123, when the chuck 123 is rotated to the second position, rotation or axial movement of the connector 210 will not interfere with the maintenance of the chuck 123 in the second position. Therefore, the brush handle 100 does not need a spring or other elastic member 130 to provide a force for maintaining clamping, and the spring or other elastic member 130 is omitted. This not only simplifies the structure design, but also avoids rusting and failure of the spring in a high-humidity working condition, thereby improving the durability of the product.

[0054] Referring to Figures 2 to 3 In the embodiment, the brush handle 100 has an unlocking state in which the chuck 123 is rotated to the first position to connect or disconnect the connector 210, and a locking state in which the chuck 123 is rotated to the second position to fix the connector 210. In the locking state, the connecting point of the connecting rod 122 and the chuck 123, the connecting point of the connecting rod 122 and the push rod 121, and the midpoint of the fixing hole 111 are collinear, and the push rod 121 is located at the end away from the chuck 123 in the sliding groove.

[0055] In the unlocked state, the opening of the clamp head 123 faces outward, and the user can easily insert or remove the connector 210, improving the convenience of replacing the brush head 200. In the locked state, the opening of the clamp head 123 faces inward, and the connector 210 is firmly fixed by the clamp head 123, avoiding falling off during use and ensuring stability.

[0056] In this embodiment, the push rod 121, the connecting rod 122, and the clamp head 123 form a crank slider mechanism, where the rotation center of the clamp head 123 and the connecting line between the clamp head 123 and the connecting rod 122 are equivalent to a crank, and the push rod 121 is equivalent to a slider. In the locked state, the push rod 121 is collinear with the connecting rod 122, i.e., the slider is collinear with the connecting rod 122. At this time, the crank slider mechanism reaches the upper dead point, i.e., the crank and the connecting rod 122 are at the farthest position of the slider, and the crank is collinear with the connecting rod 122. In the locked state, the collinearity of the three points makes the mechanism reach the "dead point" of motion, at which time the push rod 121, the connecting rod 122, and the clamp head 123 are mutually restricted, and any external force (such as rotation or axial movement of the connector 210) is difficult to drive the clamp head 123 out of the locked state. Through such a crank slider mechanism, the brush handle 100 does not need a spring or other elastic member 130 to maintain the lock after entering the locked state, further improving the stability of the brush handle 100 in the locked state.

[0057] Referring to Figure 4 In this embodiment, the end portion 212 includes a rotating portion 2121 and an access portion 2122. The rotating portion 2121 is a hemispherical structure connected to the neck portion 211, and the access portion 2122 is a tapered structure connected to the rotating portion 2121. The hemispherical structure allows the brush head 200 to rotate freely and swing between gaps in the length direction and width direction of the through slot, enabling it to adjust its posture according to the use angle and adapt to different shapes of the toilet surface, especially for cleaning dead corners and curved areas. Users do not need to frequently adjust the wrist angle to cover a larger cleaning range, and the operation is more flexible. The tapered design can guide the end portion 212 to smoothly pass through the connecting hole 112 into the clamping cavity of the clamp head 123, reducing the difficulty of connection caused by inaccurate alignment. The gradual shrinking property of the tapered shape enables the end portion 212 to quickly find the position of the connecting hole 112, simplifying the installation process of the brush head 200 and the brush handle 100. After entering the clamping cavity, the tapered access portion 2122 gradually transitions to the hemispherical rotating portion 2121, forming a smooth connection that ensures smooth insertion and does not affect the rotating function of the brush head 200.

[0058] Referring to Figures 5 to 6In the embodiment, the push rod 121 is provided with a fixing groove 1211, and the accommodating cavity is further provided with an abutting plate 113. The abutting plate 113 is arranged in the fixing groove 1211 and is in sliding connection with the fixing groove 1211. The brush handle 100 further comprises an elastic member 130. The elastic member 130 is arranged in the fixing groove 1211. One end of the elastic member 130 abuts against the abutting plate 113, and the other end of the elastic member 130 abuts against a wall surface of the fixing groove 1211 away from the chuck 123. Under the action of the elastic member 130, the push rod 121 has a tendency to move away from the chuck 123.

[0059] The abutting plate 113 is embedded in the fixing groove 1211 and is in sliding connection, which limits the movement direction of the push rod 121 and enables the push rod 121 to stably move in the axial direction along the sliding groove, prevents the push rod 121 from tilting or shaking, and improves the reliability and accuracy of the movement of the push rod 121. The fixing groove 1211 and the abutting plate 113 form a stable guide mechanism, which helps to reduce the lateral force received by the push rod 121 during use and prolong the service life of the assembly. The elastic member 130 provides a restoring force for the push rod 121, so that the push rod 121 always has a tendency to move away from the chuck 123. After the user releases the push rod 121, the elastic member 130 automatically pushes the push rod 121 back to the original position, reducing the complexity of user operation. Under the action of the elastic member 130, the push rod 121 tends to move away from the chuck 123, and the chuck 123 is maintained in the locked state by the continuous elastic force. This design effectively prevents the brush head 200 from loosening or falling off, improves the safety and reliability of the clamping, and reduces the generation of the loosening phenomenon of the brush head 200 caused by user misoperation.

[0060] Referring to Figures 7 to 8 In the embodiment, the brush handle 100 further comprises a push button 140. The handle cover 110 is provided with a second sliding groove 114. One end of the push button 140 is arranged on the handle cover 110, and the other end of the push button 140 passes through the second sliding groove 114 and is connected with the push rod 121. Under the action of an external force, the push button 140 moves along the second sliding groove 114 to drive the push rod 121 to move along the first sliding groove. The push button 140 is connected with the push rod 121 through the second sliding groove 114, so that the user can indirectly control the movement of the push rod 121 through the operation of the push button 140 without directly contacting the push rod 121, thereby simplifying the operation steps. The second sliding groove 114 provides a clear movement track for the push button 140, ensuring that the push rod 121 can stably move in a predetermined direction along the first sliding groove, and reducing the jamming or failure caused by operation errors.

[0061] Referring to Figures 7 to 8In this embodiment, the push button 140 is further provided with a clamping protrusion 141, and the second sliding groove 114 is provided with a positioning groove 115 corresponding to the clamping protrusion 141. The positioning groove 115 includes a first clamping groove 116 arranged at one end of the second sliding groove 114 close to the clamp head 123, and a second clamping groove 117 arranged at the other end of the second sliding groove 114 away from the clamp head 123. In the unlocked state, the clamping protrusion 141 is clamped with the first clamping groove 116, and in the locked state, the clamping protrusion 141 is clamped with the second clamping groove 117.

[0062] The cooperation of the clamping protrusion 141 and the positioning groove 115 can make the push button 140 accurately stay at the predetermined position during operation, avoiding the situation that the sliding is not in place. When the clamping protrusion 141 enters the positioning groove 115, a clear clamping feeling is generated, providing feedback to the user, so that the user knows that the operation has been completed, improving the reliability and experience of the operation. In the unlocked state, the clamping protrusion 141 is clamped with the first clamping groove 116, so that the push button 140 will not move due to accidental touch, ensuring the stability of the unlocked state; similarly, in the locked state, the clamping protrusion 141 is clamped with the second clamping groove 117, ensuring the reliability of the locked state. The clamping structure 160 can prevent the push button 140 from accidentally sliding due to external force or vibration during use, enhancing the stability of the connection or release state of the brush head 200. The user only needs to slide the push button 140 from the first clamping groove 116 to the second clamping groove 117 (or in the reverse direction) to complete the state switching, which is simple and intuitive.

[0063] In this embodiment, the handle cover 110 includes a front cover and a rear cover connected to each other, and the front cover and the rear cover jointly form the accommodation cavity. The push rod 121 includes a front rod and a rear rod connected to each other, one end of the front rod is connected to the connecting rod 122, and the other end is connected to the rear rod. The combination of the front cover and the rear cover forms the accommodation cavity, which facilitates the reduction of manufacturing difficulty through split processing during manufacturing, and facilitates the assembly of internal components (such as the push rod 121 and the connecting rod 122). Through the split design, the handle cover 110 can be disassembled, which is convenient for users to clean the internal accommodation cavity or maintain the internal components, and improves the maintainability and service life of the product. The split design of the handle cover 110 facilitates mold processing and assembly of internal parts, and the modular design of the push rod 121 makes the production, transportation and assembly of parts more convenient, improving production efficiency. The segmented design of the front rod and the rear rod of the push rod 121 facilitates the adjustment of size or replacement of parts according to different needs, and the split design of the front cover and the rear cover of the handle cover 110 also supports modification of different sizes or shapes. The split handle cover 110 and the modular push rod 121 design reduce the processing complexity of the overall parts, reduce the scrap rate, reduce the production cost, and at the same time improve the economy of maintenance and replacement.

[0064] Referring to Figure 9 and Figure 10In the embodiment, the front rod and the rear rod are connected through the clamping structure 160, the clamping structure 160 includes a plurality of clamping claws 161 and a clamping hole 162, one of the front rod and the rear rod is provided with a plurality of clamping claws 161, and the other is provided with a clamping hole 162 corresponding to the clamping claws 161, and the clamping claws 161 and the clamping hole 162 are arranged on the push rod 121 in a predetermined rule.

[0065] The clamping claws 161 and the clamping hole 162 are arranged around the push rod 121, and a plurality of connection points are distributed on the circumference of the push rod 121, forming uniform force distribution, significantly improving the connection strength of the front rod and the rear rod, and avoiding the problems of loosening or disconnection caused by single-point connection. The clamping mode of the clamping claws 161 and the clamping hole 162 does not require threads or welding, and users or production lines can quickly complete assembly, improving assembly efficiency. The regular arrangement of the clamping claws 161 and the clamping hole 162 provides multi-point positioning, ensuring the accurate alignment of the front rod and the rear rod in the circumferential direction when connected, avoiding radial misalignment or inclination after connection. The uniformly distributed clamping claws 161 and clamping holes 162 reduce the possibility of force on a single part, and the multi-point clamping provides uniform connection force distribution in the circumferential direction, effectively preventing the front rod and the rear rod from disconnection or loosening, and ensuring the overall structural strength of the push rod 121. The clamping structure 160 uniformly distributes the radial load, avoids force concentration, makes the push rod 121 more durable when subjected to external impact, and prolongs the service life.

[0066] Referring to Figures 11 to 14 The application also provides a toilet brush system with a replaceable brush head, which comprises the above-mentioned toilet brush with a replaceable brush head, and further comprises a base 300, the base 300 comprising a face plate 310 and a shell 320 connected in rotation, the face plate 310 and the shell 320 forming a rotating pair through a rotating shaft 321 arranged in the shell 320, the face plate 310 being provided with a mounting bracket 311 for accommodating the brush head 200, the shell 320 having an inner cavity for accommodating the mounting bracket 311, the shell 320 being further provided with a jack 322 adapted to accommodate the brush handle 100, the mounting bracket 311 being provided with an abutting portion 312 on the side away from the face plate 310, the abutting portion 312 being arranged corresponding to the jack 322 for abutting the brush handle 100, the face plate 310 having a closed state completely adhering to the shell 320 under the gravity of the brush handle 100, and an open state in which the face plate 310 is rotated to the opening of the mounting bracket 311 extending out of the inner cavity under the gravity of the brush handle 100 after the brush handle 100 is pulled out of the jack 322.

[0067] Referring to Figures 13 to 14When the brush handle 100 is inserted into the insertion hole 322, the face plate 310 is fully attached to the shell 320 under the action of gravity of the brush handle 100, ensuring that the overall appearance of the base 300 is neat and beautiful. When the brush handle 100 is pulled out, the face plate 310 is rotated to an open state under the action of gravity, exposing the opening of the mounting rack 311, facilitating the user to take out or replace the brush head 200, and improving the operation convenience. The automatic opening and closing design of the face plate 310 reduces the steps of user operation, making the use of the toilet brush more intuitive and efficient. In the embodiment, the face plate 310 is rotated out of the shell 320 as a whole in the open state, so that the mounting rack 311 is fully exposed, and the user can easily take out or place the brush head 200, avoiding the inconvenience caused by the obstruction of the shell 320. After the face plate 310 is rotated out, the inner cavity of the shell 320 can be prevented from being polluted by residual water droplets or dirt, and the internal area is convenient for cleaning.

[0068] Referring to Figures 12 to 14 In the embodiment, the brush handle 100 is also provided with a magnetic ring 150, which is arranged in the accommodating cavity at one end close to the brush head 200. A magnet 313 is correspondingly arranged on the abutting portion 312, and the magnetic ring 150 is adsorbed and connected with the magnet 313. When the brush handle 100 is pulled out of the insertion hole 322 under the action of external force, the face plate 310 is rotated under the action of magnetic force to separate from the closed state. The magnetic attraction design enables the brush handle 100 to be automatically attracted to the position after being inserted into the insertion hole 322, and to drive the face plate 310 to rotate when being pulled out

[0069] The adsorption force between the magnetic ring 150 and the magnet 313 enables the brush handle 100 to be automatically aligned and attracted to the position after being inserted into the insertion hole 322, without the need for the user to accurately adjust the position, thereby improving the operation convenience. The magnetic attraction provides additional fixing force, and the brush handle 100 is more firmly fixed in the insertion hole 322, avoiding the shaking or loosening phenomenon caused by position deviation or slight vibration. When the brush handle 100 is pulled out under the action of external force, the brush handle 100 is pulled out due to the adsorption between the magnetic ring 150 and the magnet 313. The adsorption force drives the face plate 310 to rotate around the rotating shaft 321. When the brush handle 100 is completely taken out, the center of gravity of the face plate 310 is deviated relative to the rotating shaft 321, and the face plate 310 is rotated to the open state under the action of its own weight, exposing the opening of the mounting rack 311, facilitating the user to store or replace the brush head 200. The user only needs to pull out the brush handle 100 to complete the opening operation of the face plate 310, without the need for manually adjusting the position of the face plate 310, thereby reducing the operation complexity.
