Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning brushes, and in particular relates to a cleaning brush head that is easy to replace quickly and a storage device thereof. Background Art

[0002] At present, sit-down toilets have entered thousands of households. Compared with squat toilets, sit-down toilets are more suitable for use by the elderly or children, and sit-down toilets are more comfortable. However, since sit-down toilets are in direct contact with the buttocks, dirt will adhere to the inner wall of the toilet after using the toilet. If they are not cleaned in time, their sanitation is actually far less hygienic than squat toilets. Ordinary cleaning brushes can be used to clean squat toilets, but they are not suitable for sit-down toilets. Because sit-down toilets are designed with grooves on the edges and siphon ports at the bottom, ordinary cleaning brushes cannot clean every corner. Therefore, a cleaning brush is designed for cleaning sit-down toilets. The brush head can be rotated at an angle so that the brush head can fit the internal glaze of the sit-down toilet and can reach every corner, making it easy to clean. In addition, replaceable brush heads have been designed. A disposable brush head is used each time the sit-down toilet is cleaned to avoid secondary pollution.

[0003] However, the current structure of the cleaning brush still has health and safety risks. The cleaning brush is generally composed of a storage tube and a handle. The brush heads are stacked in the storage tube. Each time cleaning is required, the lid must be manually opened first, and then the handle is picked up and inserted into the storage tube to clamp the brush head and then clean the toilet. Many people do not close the lid after cleaning. The storage tube in the open state is easily contaminated by spraying bath water or other things, and the brush head will be used less and less during the gradual use. The brush head at the bottom is not only difficult to clamp accurately with the handle, but the end of the handle itself will enter the water in the toilet. Once its end touches the inner wall of the storage tube, it will directly cause contamination in the storage tube, thereby causing the brush head to easily deteriorate or lose its cleaning function. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cleaning brush head that is easy to quickly replace and a storage device for it. Each time the handle is inserted, the cleaning brush head is pushed up and locked, so that each time the barrel cover is opened, there is always a cleaning brush head at the top, which is convenient for clamping the handle and can automatically drop the barrel cover to ensure that the cleaning brush head in the barrel is clean.

[0032] Furthermore, the cleaning brush head 6 storage device is used to store the cleaning brush head 6, and the cleaning brush head 6 is a structure of an upper snap-fit ​​seat 61 and a lower brush body 62.

The cleaning brush head 6 at the bottom is placed on the lifting plate 532. The snap-fit ​​seat 61 on the cleaning brush head 6 at the bottom of each group is embedded in the snap-fit ​​portion 63 of the upper cleaning brush head 6. The outer side walls of several of the cleaning brush heads 6 are abutted against the limiting portion 5231.

[0033] Description of the working method of the present invention:

[0034] The cleaning brush head and its storage device that are easy to replace quickly adopt this structure, first of all, the function of the barrel 1 is to accommodate the cleaning brush head 6, and the handle-mounting barrel 4 installed on the outer wall of the barrel 1 is used to place the handle 3. A plurality of cleaning brush heads 6 are stacked in sequence in the storage cavity 534 enclosed by the enclosing plate 533 in the barrel 1. In order to ensure that the top cleaning brush head 6 can abut under the barrel cover 2 when the handle 3 is inserted, so that the handle 3 can be buckled on the top cleaning brush head 6 without touching the inner wall of the barrel 1 when it is used next time, because the handle 3 clamps the cleaning brush head 6, it belongs to the existing technology, so in There is no need to elaborate on how to buckle the cleaning brush head 6 and fix it. In order to ensure that the stacked cleaning brush heads 6 can remain lifted up and abut against the bottom of the barrel cover 2, a lifting plate 532 is placed in the accommodating cavity 534. The cleaning brush head 6 is lifted up and abutted against the bottom of the barrel cover 2 by the supporting force provided by the spring 531 below the lifting plate 532. The weight of the barrel cover 2 is set to be a heavy object, so that it can press the cleaning brush head 6 underneath without being pushed out. However, if this setting does not have a limiting means, the topmost cleaning brush head 6 will be pushed out of the barrel body 1 when the barrel cover 2 is opened, causing the cleaning brush head 6 to fall and be contaminated.

[0035] Therefore, a plurality of movable grooves 5241 distributed in a longitudinal array are provided on the mounting seat 524, and a limiting head 523 is placed in the movable groove 5241, so that the limiting portion 5231 on the limiting head 523 extends into the cylinder body 1 in a downwardly inclined state under the action of gravity and abuts against the outer side wall of the stacked cleaning brush heads 6, ensuring that only the topmost cleaning brush head 6 will not be limited, while the cleaning brush heads 6 below it remain in the 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 for use. However, the limiting portion 5231 abutting against the cleaning brush head 6 can indeed prevent the cleaning brush head 6 below from being lifted up and falling out of the cylinder body 1, but it cannot achieve the effect of automatic rising. Therefore, in a plurality of groups of movable grooves 52 A longitudinal electromagnet 522 is provided at the rear opening of 41. When the electromagnet 522 is energized, the electromagnet 522 generates magnetism, which will attract the magnetic attraction sheet 5232 at the rear end of the limit head 523, so that the limit head 523 moves toward the direction of the electromagnet 522 and exits the cylinder body 1. Therefore, when the electromagnet 522 is energized, the limit part 5231 will release the limiting effect on the cleaning brush head 6, so that when the first cleaning brush head 6 has been taken out and the cylinder cover 2 is closed, the electromagnet 522 is energized so that the cleaning brush head 6 below is abutted against the bottom of the cylinder cover 2 under the action of the spring 531, and then the electromagnet 522 is disconnected from the power supply, and the limit head 523 falls back again under the action of gravity and engages on the cleaning brush head 6 for limiting again.

[0036] After the handle 3 is used, it needs to be reinserted into the handle-mounting tube 4 for placement. In the process of placing the handle 3, the cleaning brush head 6 below can be lifted up for standby use. Therefore, two sets of parallel magnetic poles 521 are provided on the handle-mounting tube 4 and the cylinder body 1 according to the principle of magnetic induction power generation. The guide frame 51 which is sleeved on the outer wall of the cylinder body 1 is embedded with electric wires. The end of the guide frame 51 is electrically connected to the electromagnet 522 through the electric wires. Moreover, the slider 512 on the guide frame 51 is matched with the guide rail 11 which is arranged in the longitudinal direction. Therefore, after the handle 3 is inserted into the handle-mounting tube 4, the guide frame 51 is moved along the guide rail 11. The handle 3 is pressed downward in the direction so that the wire cuts the magnetic flux lines between the two sets of magnetic poles 521, thereby generating current to supply power to the electromagnet 522. Therefore, the electromagnet 522 will be energized as the handle 3 is pressed downward, and will be de-energized as the handle 3 stops. In order to achieve a larger current, a guide plate can be added to the guide frame 51 in the handle tube 4, and a wire of sufficient length can be wound therein to generate a larger current in the process of cutting the magnetic flux lines. The current generated by the wire cutting the magnetic flux lines can also be used as a starting current. When current is generated, the electromagnet 522 is additionally energized from an external power source, and the power is disconnected when no current is generated.

[0037] Since the insertion of the handle 3 into the handle tube 4 will cause the guide frame 51 to cut the magnetic flux lines and generate current, when the handle 3 is pulled out of the handle tube 4, in order to ensure that the guide frame 51 can move upward with the handle 3, an iron sheet 511 is added to the guide frame 51 in the handle tube 4. The iron sheet 511 is adsorbed on the magnetic suction 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 adsorption effect. Therefore, the guide frame 51 will also cause the magnetic flux lines to be cut to generate current. In fact, once the limit on the cleaning brush head 6 is released when the handle 3 is pulled out, the cleaning brush head 6 may be pushed and fly out when the tube cover 2 is opened. Current can be generated before the barrel cover 2 is opened, and the cleaning brush head 6 can still be prevented from flying out through the pressing effect of the barrel cover 2. No current can be generated after the barrel cover 2 is opened, 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 barrel 1 is higher than the highest point of the magnetic pole 521 on the handle barrel 4, and the highest point of the guide groove 41 is between the highest points of the two groups of magnetic poles 521 and close to the magnetic pole 521 on the outer wall of the barrel 1. Therefore, within a certain distance when the handle 3 is just inserted into the handle barrel 4, the magnetic flux lines will not be cut to generate current. Similarly, when the handle 3 is pulled out, the magnetic flux lines will not be cut to generate current near the top.

[0038] In order to realize the opening and closing of the tube cover 2 as the guide frame 51 moves up and down, a pushing plate 21 is arranged at the edge of the tube cover 2, and an upwardly extending pushing column 514 is arranged on the guide frame 51, and the arc surface 515 on the pushing column 514 abuts against the pushing plate 21. Therefore, in the process of pulling out the handle 3, when the iron sheet 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 tube 4, the arc surface 515 just abuts against the bottom of the pushing plate 21. In the process of keeping the guide frame 51 moving upward, since the magnetic flux lines are not cut, no current is passed through the electromagnet 522, and the limit head 523 maintains the limiting effect on the cleaning brush head 6, while the arc surface 515 keeps moving upward to open the pushing plate 21 until the guide frame 51 moves to the end of the guide groove 41, and the tube cover 2 is opened.

[0039] In order to ensure that the guide frame 51 remains in place after the handle 3 is pulled out, a plurality of 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 that in the absence of external force, the guide frame 51 will remain at the upper position without moving.

[0040] The beneficial effect of the present invention is that by pulling out the handle 3 on the handle-mounting tube 4, the guide frame 51 is driven to move upward and the tube cover 2 is opened, and the plurality of stacked cleaning brush heads 6 in the accommodating cavity 534, the first one at the top is located below the tube cover 2 for use, and the other cleaning brush heads 6 at their lower ends are clamped by the limit head 523, which is convenient for personnel to take and use them. After the handle 3 is inserted into the handle-mounting tube 4, the guide frame 51 is pushed downward, so that the wires therein cut the magnetic flux lines between the two groups of magnetic poles 521, thereby generating current to power the electromagnet 522, so that the electromagnet 522 generates magnetic force and attracts the limit head 523 to move backward, and the cleaning brush head 6 that loses 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 tube cover 2, realizing the step-by-step upward movement of the cleaning brush head 6, ensuring that the cleaning brush head 6 at the top can be taken each time the tube cover 2 is opened.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
