Description
Technical Field
[0001] This invention belongs to the field of cleaning brush technology, specifically relating to a cleaning brush head that is easy to replace quickly and its storage device. Background Technology
[0002] Currently, sit-down toilets have become commonplace in households. Compared to squat toilets, sit-down toilets are more suitable for the elderly or children due to their greater comfort. However, because sit-down toilets come into direct contact with the buttocks, some residue tends to accumulate on the inner wall after use. Without timely cleaning, their hygiene is far inferior to that of squat toilets. While ordinary cleaning brushes can clean squat toilets, they are not suitable for sit-down toilets. This is because sit-down toilets have grooves along the edges and a siphon at the bottom, making it difficult for ordinary cleaning brushes to reach the corners. Therefore, a special cleaning brush designed for sit-down toilets has been developed. This brush head can rotate to fit the inner glaze of the toilet bowl, ensuring thorough cleaning of even the most difficult corners. Furthermore, replaceable brush heads are now available, allowing for disposable brush heads each time the toilet is cleaned, preventing secondary contamination.
[0003] However, the current design of cleaning brushes still poses hygiene and safety risks. These brushes typically consist of a storage tank and a handle. The brush heads are stacked inside the storage tank. Each time cleaning is needed, the lid must be manually opened first, and then the handle must be used to reach into the storage tank to retrieve the brush heads for cleaning the toilet. Many people do not close the lid after cleaning, and the storage tank, when open, is easily contaminated by shower water or other substances. Moreover, as the brush heads are used, they become fewer and fewer. Not only are the brush heads at the bottom difficult to hold accurately with the handle, but the end of the handle itself can also get into the toilet bowl. If the end of the handle touches the inner wall of the storage tank, it will directly cause contamination inside the storage tank, leading to the brush heads easily deteriorating or losing their cleaning effect. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a cleaning brush head and its storage device that are easy to replace quickly. By pushing the cleaning brush head upward and locking it in place each time the handle is inserted, the cleaning brush head is always at the top when the cylinder cover is opened. This makes it easy to hold the handle while automatically lowering the cylinder cover to ensure the cleanliness of the cleaning brush head inside the cylinder.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A cleaning brush head storage device for easy and quick replacement includes a cylinder, a cap, a handle, a handle holder, and a lifting assembly. The cap is rotatably connected to and covers the upper opening of the cylinder. The handle holder is detachably connected to the side wall of the cylinder. The handle is inserted into and engages with the upper opening of the handle holder.
[0007] The lifting assembly includes a guide frame, a magnetic component, and a lifting component. The guide frame has an embedded wire and is fitted onto the outer wall of the cylinder. One end of the guide frame is movably connected to the handle cylinder. The lifting component is disposed inside the cylinder and includes a spring and a lifting plate. The lifting plate is connected to the bottom surface of the cylinder by the spring and faces the cylinder cover.
[0008] The magnetic component includes two magnetic poles, an electromagnet, a limiting head, and a mounting base. The two magnetic poles are respectively connected to the handle-mounting cylinder. The electromagnet is disposed on the side wall of the cylinder. The other end of the guide frame is electrically connected to the electromagnet via a wire. The limiting head is movably connected to the side wall of the cylinder and extends into the cylinder. During the insertion of the handle into the handle-mounting cylinder, the guide frame inside the cylinder is pressed down. The guide frame cuts the magnetic field lines between the two magnetic poles and energizes the electromagnet. The energized electromagnet generates a magnetic field that attracts the limiting head out of the cylinder. The two magnetic poles are respectively disposed on the outer wall of the cylinder and the outer wall of the handle-mounting cylinder, and the two magnetic poles are parallel to each other. The highest point of the magnetic pole on the outer wall of the cylinder is higher than the highest point of the magnetic pole on the handle-mounting cylinder. The outer wall of the handle-mounting cylinder is provided with a downward-opening guide groove. The highest point of the guide groove is located between the highest points of the two magnetic poles. The guide frame is movably connected to the guide groove. An iron plate is provided on the guide frame located inside the handle-mounting cylinder. The iron plate is magnetically connected to the magnetic suction plate at the end of the handle. The mounting base is detachably connected to the side wall of the cylinder. The mounting base is provided with several movable grooves arranged in a longitudinal array. The electromagnet is arranged longitudinally and covers the openings of several movable grooves. The limiting head includes several sets. The several sets of limiting heads are respectively matched in several movable grooves. The limiting part at the front end of the limiting head extends into the cylinder in a downward-sloping manner. The magnetic suction plate at the rear end of the limiting head corresponds to the electromagnet.
[0009] The outer wall of the cylinder is also provided with a longitudinally arranged guide rail, and the guide frame is provided with a slider, which is embedded in and movably connected to the guide rail; the inner wall of the guide frame is provided with a number of circumferentially distributed damping blocks, which can abut against and be connected to the outer wall of the cylinder.
[0010] The edge of the cylinder cover is provided with a push plate, and the guide frame is provided with an upwardly extending push column. The arc-shaped surface at the upper end of the push column can be connected to the push plate during the upward displacement of the guide frame.
[0011] Furthermore, the lifting component also includes a surrounding plate, which is arc-shaped and vertically arranged inside the cylinder. The surrounding plate and the inner wall of the cylinder enclose a housing cavity, and the lifting plate and spring are both located inside the housing cavity.
[0012] Furthermore, the cleaning brush head storage device is used to store cleaning brush heads. The cleaning brush head has a structure with an upper fastening seat and a lower brush body. The brush body has an upwardly recessed fastening part in the middle. Several cleaning brush heads are stacked in sequence and embedded in the storage cavity. The bottom cleaning brush head is placed on the lifting plate. The fastening seat on each group of lower cleaning brush heads is embedded in the fastening part of the upper cleaning brush head. The outer walls of several cleaning brush heads are connected to the limiting part in an abutment manner.
[0013] Compared with the prior art, the advantages of this invention are as follows: by pulling out the handle on the handle-holding cylinder, the guide frame is moved upward and the cylinder cover is opened, allowing several stacked cleaning brush heads inside the housing cavity to be placed. The topmost brush head is positioned below the cylinder cover for use, while the other cleaning brush heads below it are held in place by limiting heads, making it convenient for personnel to pick them up and use. After inserting the handle into the handle-holding cylinder, the guide frame is pushed downward, causing the wire inside to cut the magnetic field lines between the two magnetic poles, thereby generating current to power the electromagnet. This causes the electromagnet to generate magnetic force and attract the limiting heads to move backward. The cleaning brush heads that have lost their limiting function are pushed by the lifting plate under the elastic force of the spring, thus abutting against the bottom of the cylinder cover. This achieves the step-by-step upward movement of the cleaning brush heads, ensuring that the topmost cleaning brush head can be accessed every time the cylinder cover is opened.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0025] The specific embodiments of the present invention will now be described with reference to the accompanying drawings:
[0026] like Figure 1-8 As shown, a cleaning brush head storage device that facilitates quick replacement includes a cylinder 1, a cylinder cover 2, a handle 3, a handle holder 4, and a lifting assembly. The cylinder cover 2 is rotatably connected to and covers the upper opening of the cylinder 1. The handle holder 4 is detachably connected to the side wall of the cylinder 1. The handle 3 is inserted into and engages with the upper opening of the handle holder 4.
[0027] The lifting assembly 5 includes a guide frame 51, a magnetic component 52, and a lifting component 53. The guide frame 51 has an embedded wire and is fitted onto the outer wall of the cylinder 1. One end of the guide frame 51 is movably connected to the handle cylinder 4. The lifting component 53 is disposed inside the cylinder 1 and includes a spring 531 and a lifting plate 532. The lifting plate 532 is connected to the bottom surface inside the cylinder 1 via the spring 531 and faces the cylinder cover 2.
[0028] The magnetic component 52 includes two magnetic poles 521, an electromagnet 522, a limiting head 523, and a mounting base 524. The two magnetic poles 521 are respectively connected to the handle-mounting cylinder 4. The electromagnet 522 is disposed on the side wall of the cylinder 1. The other end of the guide frame 51 is electrically connected to the electromagnet 522 via a wire. The limiting head 523 is movably connected to the side wall of the cylinder 1 and extends into the cylinder 1. When the handle 3 is inserted into the handle-mounting cylinder 4, it presses down on the guide frame 51 inside the handle-mounting cylinder 4. The guide frame 51 cuts the magnetic field lines between the two magnetic poles 521 and energizes the electromagnet 522. The energized electromagnet 522 generates a magnetic field that attracts the limiting head 523 out of the cylinder 1. The two magnetic poles 521 are respectively disposed on the outer side wall of the cylinder 1 and the outer side wall of the handle-mounting cylinder 4. The two magnetic poles 521 are parallel to each other. The highest point of the magnetic pole 521 on the outer side wall of the cylinder 1 is higher than the highest point of the magnetic pole 521 on the handle-mounting cylinder 4. The outer wall of the handle-mounted cylinder 4 is provided with a downward-opening guide groove 41. The highest point of the guide groove 41 is between the highest points of the two magnetic poles 521. The guide frame 51 is movably connected to the guide groove 41. An iron plate 511 is provided on the guide frame 51 located in the handle-mounted cylinder 4. The iron plate 511 is magnetically connected to the magnetic suction plate 31 at the end of the handle 3. The mounting base 524 is detachably connected to the side wall of the cylinder 1. The mounting base 524 is provided with a plurality of movable grooves 5241 arranged in a longitudinal array. The electromagnet 522 is arranged longitudinally and covers the openings of the plurality of movable grooves 5241. The limiting head 523 includes a plurality of sets. The plurality of sets of limiting heads 523 are respectively matched in the plurality of movable grooves 5241. The limiting part 5231 at the front end of the limiting head 523 extends into the cylinder 1 in a downward-sloping manner. The magnetic suction plate 5232 at the rear end of the limiting head 523 corresponds to the electromagnet 522.
[0029] The outer side wall of the cylinder 1 is also provided with a longitudinally arranged guide rail 11, and the guide frame 51 is provided with a slider 512, which is embedded in and movably connected to the guide rail 11; the inner side wall of the guide frame 51 is provided with a plurality of circumferentially distributed damping blocks 513, which can abut against and be connected to the outer side wall of the cylinder 1.
[0030] The edge of the cylindrical cover 2 is provided with a push plate 21, and the guide frame 51 is provided with an upwardly extending push column 514. The arc-shaped surface 515 at the upper end of the push column 514 can be connected to the push plate 21 during the upward displacement of the guide frame 51.
[0031] Furthermore, the lifting component 53 also includes a surrounding plate 533, which is arc-shaped and vertically arranged inside the cylinder 1. The surrounding plate 533 and the inner wall of the cylinder 1 enclose a housing cavity 534, and the lifting plate 532 and the spring 531 are both located inside the housing cavity 534.
[0032] Furthermore, the cleaning brush head 6 storage device is used to store the cleaning brush head 6. The cleaning brush head 6 has an upper fastening seat 61 and a lower brush body 62. The brush body 62 has an upwardly recessed fastening part 63 in the middle. Several cleaning brush heads 6 are stacked in sequence and embedded in the storage cavity 534. The bottom cleaning brush head 6 is placed on the lifting plate 532. The fastening seat 61 on each group of lower cleaning brush heads 6 is embedded in the fastening part 63 of the upper cleaning brush head 6. The outer side walls of several cleaning brush heads 6 are connected to the limiting part 5231 in an abutmentable manner.
[0033] Description of the working principle of this invention:
[0034] The cleaning brush head and its storage device with this structure, which facilitates quick replacement, primarily uses a cylindrical body 1 to house the cleaning brush heads 6. A handle-mounted cylinder 4, installed on the outer wall of the cylindrical body 1, is used to hold the handle 3. Several cleaning brush heads 6 are stacked sequentially within the storage cavity 534 formed by the inner enclosure plate 533 of the cylindrical body 1. To ensure that the uppermost cleaning brush head 6 abuts against the bottom of the cylinder cover 2 when the handle 3 is inserted, so that the handle 3 can be fastened to the topmost cleaning brush head 6 during the next use without touching the inner wall of the cylindrical body 1, and since the handle 3's method of gripping the cleaning brush head 6 is existing technology, therefore... This will not be elaborated on in detail on how the cleaning brush head 6 is secured. In order to keep the stacked cleaning brush head 6 rising and abutting against the bottom of the cover 2, a lifting plate 532 is placed in the housing cavity 534. The lifting plate 532 is supported by the spring 531 to lift the cleaning brush head 6 and abut against the bottom of the cover 2. The weight of the cover 2 is set as a heavy object so that it can press the cleaning brush head 6 down and prevent it from being pushed out. However, if this setting does not have a limiting means, the top cleaning brush head 6 will be pushed out of the cylinder 1 when the cover 2 is opened, causing the cleaning brush head 6 to fall and become contaminated.
[0035] Therefore, several movable slots 5241 arranged in a longitudinal array are provided on the mounting base 524. A limiting head 523 is placed within each movable slot 5241, causing the limiting part 5231 on the limiting head 523 to extend downwards into the cylinder 1 under the influence of gravity, abutting against the outer wall of the stacked cleaning brush heads 6. This ensures that only the topmost cleaning brush head 6 is not limited, while the cleaning brush heads 6 below it remain in their original position due to being stuck. Therefore, even if the cylinder cover 2 is opened, only the topmost cleaning brush head 6 can be taken out and used. While the limiting part 5231 abutting against the cleaning brush head 6 does prevent the lower cleaning brush heads 6 from being pushed up and detached from the cylinder 1, it does not achieve an automatic lifting effect. Therefore, in several sets of movable slots 5241... A longitudinal electromagnet 522 is installed at the rear opening of 41. When the electromagnet 522 is energized, it generates magnetism, which attracts the magnetic plate 5232 at the rear end of the limiting head 523. This causes the limiting head 523 to move towards the electromagnet 522 and exit into the cylinder 1. Therefore, when the electromagnet 522 is energized, the limiting part 5231 will release its limiting effect on the cleaning brush head 6. This allows the cleaning brush head 6 to be placed against the bottom of the cylinder 2 under the force of the spring 531 after the first cleaning brush head 6 has been taken out and the cylinder cover 2 has been closed. When the electromagnet 522 is energized, the lower cleaning brush head 6 will be pressed against the bottom of the cylinder cover 2 by the force of the spring 531. When the electromagnet 522 is de-energized, the limiting head 523 will fall back under the action of gravity and lock onto the cleaning brush head 6 for a second limiting.
[0036] Since the handle 3 needs to be reinserted into the handle holder 4 after use, the cleaning brush head 6 below can be lifted up for later use during the placement process. Therefore, based on the principle of magnetic induction, two parallel magnetic poles 521 are set on the handle holder 4 and the cylinder 1. An electric wire is embedded in the guide frame 51, which is fitted onto the outer wall of the cylinder 1. The end of the guide frame 51 is electrically connected to the electromagnet 522 via an electric wire. Furthermore, the slider 512 on the guide frame 51 engages with the longitudinally arranged guide rail 11. Therefore, when the handle 3 is inserted into the handle holder 4, the guide frame 51 moves along the guide rail 11... Pressing down causes the wire to cut the magnetic field lines between the two magnetic poles 521, thereby generating current to power the electromagnet 522. Therefore, the electromagnet 522 will be energized when the handle 3 is pressed down and de-energized when the handle 3 is stopped. In order to achieve a larger current, a guide plate can be added to the guide frame 51 inside the handle sleeve 4, and a wire of sufficient length can be wound inside it to generate a larger current during the cutting of magnetic field lines. Alternatively, the current generated by the wire cutting the magnetic field lines can be used as the starting current. When current is generated, an external power source can provide additional power to the electromagnet 522. When no current is generated, the power supply is disconnected.
[0037] Because inserting the handle 3 into the handle holder 4 causes the guide frame 51 to cut magnetic lines of force and generate current, an iron plate 511 is added to the guide frame 51 inside the handle holder 4 to ensure that the guide frame 51 moves upward with the handle 3 when the handle 3 is pulled out of the handle holder 4. The iron plate 511 is attracted to the magnetic plate 31 at the end of the handle 3. Therefore, when the handle 3 is pulled out, the guide frame 51 will also move upward due to the attraction, and the guide frame 51 will also cause the magnetic lines of force to be cut and generate current. In fact, once the restriction on the cleaning brush head 6 is released when the handle 3 is pulled out, the cleaning brush head 6 may be pushed out when the cap 2 is opened. Therefore, when pulling out the handle 3, when opening the cap 2, the guide frame 51 should be adjusted accordingly. Before opening the cap 2, current can be generated. The pressure of the cap 2 can still prevent the cleaning brush head 6 from flying out. After opening the cap 2, no current can be generated, ensuring that the cleaning brush head 6 can be limited by the limiting head 523. Therefore, the highest point of the magnetic pole 521 on the outer wall of the cylinder 1 is higher than the highest point of the magnetic pole 521 on the handle cylinder 4. The highest point of the guide groove 41 is between the highest points of the two magnetic poles 521 and close to the magnetic pole 521 on the outer wall of the cylinder 1. Therefore, when the handle 3 is just inserted into the handle cylinder 4, it will not cut the magnetic field lines and generate current. Similarly, when the handle 3 is pulled out, it will not cut the magnetic field lines and generate current near the top.
[0038] In order to enable the cap 2 to open and close as the guide frame 51 moves up and down, a push plate 21 is provided at the edge of the cap 2, and an upwardly extending push post 514 is provided on the guide frame 51. The arc-shaped surface 515 on the push post 514 abuts against the push plate 21. Therefore, when the handle 3 is pulled out, when the iron piece 511 at the end of the handle 3 drives the guide frame 51 to move to a point higher than the highest point of the magnetic pole 521 on the handle cylinder 4, the arc-shaped surface 515 just abuts against the bottom of the push plate 21. During the upward movement of the guide frame 51, since no magnetic lines of force are cut, no current is supplied to the electromagnet 522. The limiting head 523 maintains the limiting effect on the cleaning brush head 6, while the arc-shaped surface 515 continues to move upward and push open the push plate 21 until the guide frame 51 moves to the end of the guide groove 41, and the cap 2 is opened.
[0039] To ensure that the guide frame 51 remains in place after the handle 3 is pulled out, several damping blocks 513 are provided on the inner wall of the guide frame 51. The damping blocks 513 abut against the outer wall of the cylinder 1, so the guide frame 51 will remain in the upper position without external force.
[0040] The beneficial effects of this invention are as follows: by pulling out the handle 3 on the handle cylinder 4, the guide frame 51 is moved upward and the cylinder cover 2 is opened, and several stacked cleaning brush heads 6 in the housing cavity 534 are placed. The top one of the brush heads is located below the cylinder cover 2 for use, while the other cleaning brush heads 6 at the bottom are held in place by the limiting head 523, making it convenient for personnel to pick them up and use. After inserting the handle 3 into the handle cylinder 4, the guide frame 51 is pushed downward, causing the wire inside to cut the magnetic field lines between the two magnetic poles 521, thereby generating current to power the electromagnet 522. This causes the electromagnet 522 to generate magnetic force and attract the limiting head 523 to move backward. The cleaning brush head 6, which has lost its limiting function, is pushed by the lifting plate 532 under the elastic force of the spring 531, thereby abutting against the bottom of the cylinder cover 2, realizing the step-by-step upward movement of the cleaning brush head 6, ensuring that the top cleaning brush head 6 can be accessed every time the cylinder cover 2 is opened.
