Description

Technical Field

[0001] The present invention belongs to the technical field of drainage devices, and particularly relates to a clogging prevention device for a mop sink. Background Art

[0002] In densely populated public places such as schools, shopping malls, hospitals, and office buildings, cleaning rooms are equipped. Among them, the mop sink, as a rinsing device for daily cleaning tools, has a high usage frequency. During the rinsing process, the filter screen at the bottom drain of the mop sink will intercept the garbage attached to the mop, such as hair, paper waste, and plastic waste. These garbage are mainly cleaned manually. The cleaning staff needs to manually remove the filter screen and clean it, which is a cumbersome and time-consuming process. Moreover, due to the time interval of manual cleaning, when the garbage generation speed exceeds the cleaning speed, it is extremely easy to cause the drain to be blocked. Once blocked, it not only affects the normal use of the mop sink, but also requires a large amount of manpower, material resources, and time to dredge the pipeline. Based on the above problems, it is necessary to improve the drain of the existing mop sink. Summary of the Invention

[0003] The purpose of this invention is to provide a clogging prevention device for a mop sink, aiming to solve the problem that the mop sink in the prior art is extremely easy to be blocked by garbage.

[0004] To solve the above problems, the present invention adopts the following technical solutions:

[0005] A clogging prevention device for a mop sink, comprising:

[0006] A filter ring, which is installed at the drain of the mop sink. Grooves are formed on the ring surface of the filter ring at equal intervals along its circumference. Filter holes are opened on the bottom of each groove and on the filter ring surface between adjacent two grooves.

[0007] A bracket, which is arranged inside the filter ring and is detachably connected to it.

[0008] A gland, which is arranged above the filter ring, and its lower end is movably connected to the bracket in a manner that can reciprocate along the axial direction of the filter ring.

[0009] Multiple cutting knives, which are arranged in a ring and installed at the lower end of the gland, and form a shearing structure with the groove wall of the groove.

[0010] The beneficial effect of the present invention is that the filter ring is installed at the drain. When the sewage carrying garbage such as hair, shredded paper, and plastic pieces flows through the filter ring, the sewage flows into the sewer from the filter holes, and the garbage stays on the filter ring. At this time, by manipulating the gland to reciprocate, the shearing structure formed by the cutting knives and the groove wall of the groove can cut these garbage into small sizes, which is convenient to flush into the sewer, thereby preventing these garbage from blocking the sewer.

[0011] Furthermore, it further includes a housing which is cylindrical. The lower end of the housing is aligned with and connected to the edge of the filter ring. Water inlets are spacedly arranged on its side wall, and the upper end of the housing can abut against the lower end of the gland to limit its position.

[0012] A further beneficial effect of the present invention is that the ventilated housing can protect the overall structure of the device, isolate it from the outside world to prevent it from being affected during the shearing process, and also prevent incorrect shearing of non-waste objects in the mop sink, such as a mop being rinsed. The water inlets arranged on the side wall of the housing can ensure the normal entry of sewage into the device interior.

[0013] Furthermore, inserting plates are equidistantly arranged at the edge of the lower end of the gland. Slots corresponding to the inserting plates are formed at the upper end of the side wall of the housing, and the inserting plates and the slots are slidably inserted.

[0014] A further beneficial effect of the present invention is that the inserting plates and the slots are used for positioning and limiting, ensuring that the gland does not undergo circumferential deflection during the up and down movement, thereby affecting the subsequent shearing work.

[0015] Furthermore, guide vanes extend from the two side edges in the horizontal direction of each water inlet towards the center of the housing, and an arc-shaped diversion channel is formed between the two guide vanes.

[0016] A further beneficial effect of the present invention is that the guide vanes are used to assist in forming a vortex of water flow inside the device. The horizontal vanes are convenient for spreading out and staying on the filter ring for garbage such as hair.

[0017] Furthermore, a plurality of vertical guide posts are fixed near the center of the lower end of the gland. A plurality of positioning retaining rings corresponding to the plurality of upper guide posts are provided at the upper end of the bracket, and a spring is connected between any corresponding set of relative guide posts and positioning retaining rings.

[0018] A further beneficial effect of the present invention is that by installing a spring in cooperation with the guide posts and the positioning retaining rings, the gland is given an automatic reset effect by using the elastic potential energy of the spring.

[0019] Furthermore, it further includes a water retaining frame which is cylindrical and sleeved outside the plurality of springs. The lower end of the water retaining frame is connected to the edge of the bracket, the upper end of the water retaining frame can be hermetically abutted against the lower end of the gland, and a plurality of groups of limiting plates corresponding to and slidably connected to the plurality of cutters are fixed on its outer side wall.

[0020] A further beneficial effect of the present invention is that by providing the water retaining frame, the plurality of springs on the bracket are prevented from being corroded by the long-term action of sewage. At the same time, the limiting plates on the outer side of the water retaining frame can prevent the cutters from shifting during the long-term operation.

[0021] Furthermore, a sealing ring groove is provided at the lower end of the gland, and the sealing ring groove is sealingly connected to the upper end of the water baffle frame.

[0022] A further beneficial effect of the present invention is that by providing a sealing ring groove at the lower end of the gland, the sealing and dryness of the internal space of the water baffle frame are further ensured.

[0023] Furthermore, each cutting knife includes a mounting portion and a blade portion, and is connected thereto through a mounting groove opened at the lower end of the gland. Screw holes are provided on both sides of the mounting groove. The mounting portion includes an insertion piece, and two wing plates located on both sides of the insertion piece and vertically fixed thereto. Screw holes are opened on the wing plates. After the insertion piece is inserted into the mounting groove, the screw holes on the wing plates are aligned with the screw holes on both sides of the mounting groove.

[0024] A further beneficial effect of the present invention is that the cutting knife is detachably mounted at the lower end of the gland through the cooperation of the insertion piece and the wing plates with the screw holes on both sides of the mounting groove in the gland, which facilitates subsequent replacement and maintenance work.

[0025] Furthermore, the ring surface of the filter ring is a slope that slopes downward from the circumferential side towards the axis, and the blade portion of the cutting knife is arranged obliquely, and the inclination angle is opposite to the inclination angle of the ring surface of the filter ring.

[0026] A further beneficial effect of the present invention is that through the crosswise inclined arrangement of the ring surface of the filter ring and the blade portion, the shearing effect is further improved.

[0027] Furthermore, it further includes a rinsing basket. The upper part of the rinsing basket is open, the bottom is connected to the top of the gland, its side wall is in a fence shape, and the inner bottom surface has an upward arc-shaped protrusion.

[0028] A further beneficial effect of the present invention is that a rinsing basket for rinsing the mop is additionally provided. When the user rinses the mop up and down in the rinsing basket, the action of pressing the gland can be completed and the effect of shearing garbage such as hair and shredded paper can be achieved.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figures 1-8As shown in the figure, the present invention provides a clogging prevention device for a mop sink, which includes a filter ring 1, a bracket 2, a gland 3, and a cutter 4. The size of the filter ring 1 is adapted to the sewer opening of the mop sink and is installed at the water outlet of the mop sink instead of the traditional floor drain. Grooves 101 are formed at equal intervals along the circumferential direction of the ring surface of the filter ring 1. In particular, in fact, both the opposite first surface and the second surface of the filter ring 1 are processed as described above, that is, the ridged area between two adjacent grooves 101 on the first surface of the filter ring 1 is also grooved on the second surface, that is, this is the bottom of the groove 101 on the second surface of the filter ring 1. In this embodiment, as Figure 4 shown, 10 grooves 101 are equally spaced on the first surface of the filter ring 1, and 10 ridged protrusions are formed between these grooves 101. On the second surface of the filter ring 1, these ridged protrusions are the grooves 101, and the bottom of the groove 101 on the first surface is the ridged protrusion on the second surface. Filter holes 102 are opened at the bottom of each groove 101 (whether on the first surface or the second surface). The filter holes 102 are strip-shaped and coincide with the radial direction of the filter ring 1. The overall material of the filter ring 1 is selected as a hard material, preferably a metal material, especially an alloy material with certain corrosion resistance and wear resistance.

[0044] The bracket 2 is integrally circular, has the same height as the filter ring 1, and is arranged inside the filter ring 1. It is detachably connected to the inner ring of the filter ring 1 by means of screwing, plugging, etc., and mainly plays a supporting role. Its material is also a hard material, preferably a metal material, especially an alloy material with good compressive resistance.

[0045] The gland 3 is integrally circular and has the same size as the filter ring 1. It is arranged parallel above the filter ring 1. The lower end of the gland 3 is movably connected to the bracket 2 in a manner that allows the gland 3 to reciprocate along the axial direction of the filter ring 1. The specific manner of this movable connection is not limited, as long as the gland 3 can satisfy reciprocating movement along the axial direction of the filter ring 1. For example, it can be connected by a telescopic connecting shaft, or simply by a sliding plug-in structure with a limiting effect, or by a foldable hinge rod. Such connection methods are conventional technical means in mechanical design, and those skilled in the art can adopt different connection methods according to actual needs such as cost, precision, flexibility, and bearing capacity to realize the connection between the gland 3 and the bracket 2, which will not be elaborated here.

[0046] A plurality of cutters 4 are provided. The plurality of cutters 4 are arranged in a ring and installed at the lower end of the gland 3. The main function of the cutters 4 is to reciprocate together with the gland 3 and shear garbage such as hair, shredded paper, and plastic sheets on the filter ring 1 during this process. In order to achieve this shearing action, the cutters 4 need to cooperate with other structures and can be completed in various cooperation ways. And the downward movement distance of the gland 3 is correspondingly set. The following is an example:

[0047] The first method is that the cutter 4 cooperates with the two groove walls of the groove body 101 to form a structure similar to scissors to complete the shearing. The two groove walls are two groove walls that are circumferentially opposite along the filter ring 1. In this method, multiple cutters 4 are circumferentially distributed along the lower end of the gland 3, and the number is twice the number of groove bodies 101. It can be regarded as two in a group, forming two shearing structures with the two groove walls of the corresponding groove body 101. At this time, the preset value of the movement of the gland 3 needs to satisfy that the cutter 4 is slightly higher than the notch of the groove body 101 in the initial state, so as to facilitate the normal interception of garbage such as hair shreds and plastic sheets. When the gland 3 is pressed down to the bottom state, the cutter 4 extends into the groove body 101 and is slightly higher than the bottom of the groove to prevent direct contact with the bottom of the groove and damage the blade edge.

[0048] The second method is also that the cutter 4 cooperates with the two groove walls of the groove body 101, except that the two groove walls are two groove walls that are opposite in the radial direction along the filter ring 1. In this method, the number of cutters 4 is twice the number of groove bodies 101, and they are arranged in two circles of different sizes. 10 in the outer circle respectively form a shearing structure with the groove walls on the radial outer side of 10 groove bodies 101; 10 in the inner circle respectively form a shearing structure with the groove walls on the radial inner side of 10 groove bodies 101. At this time, the preset value of the movement of the gland 3 needs to meet the same condition that it is slightly higher than the notch of the groove body 101 in the initial state, so as to facilitate the normal interception of garbage such as hair shreds and plastic sheets. When the gland 3 is pressed down to the bottom state, the cutter 4 extends into the groove body 101 and is slightly higher than the bottom of the groove to prevent direct contact with the bottom of the groove and damage the blade edge.

[0049] The third method is different from the previous two. The number of cutters 4 and the water filter holes 102 correspond one by one and are arranged in alignment. This method will form two shearing structures. The first is that the cutter 4 forms a shearing structure with the hole wall of the water filter hole 102 on the ridge-like protrusion. Since the water filter hole 102 is strip-shaped, therefore, it can cooperate with the cutter 4 to achieve a shearing effect. The second is that the cutter 4 cooperates with the notch of the groove body 101. This cooperation method can cut garbage such as hair shreds like other cooperation methods, and has a better effect when facing slightly harder plastic sheet garbage. When the plastic sheet is intercepted by the filter ring 1 and overlaps on the notch of the groove body 101, after the corresponding cutter 4 moves downward, because the plastic sheets on both sides are in a suspended state, it is easier to bend under the action of the cutter 4 and finally be cut off. The preset value of the movement of the gland 3 in the third method is the same as the previous two, and will not be elaborated here.

[0050] Through the above structure, the present invention provides a clogging prevention device for a mop sink. During specific use, the filter ring 1 is installed at the water outlet. When sewage carrying garbage such as hair, shredded paper, and plastic pieces flows through the filter ring 1, the sewage flows into the sewer from the water filtering holes 102, and the garbage stays on the filter ring 1. At this time, by manipulating the gland 3 to move reciprocally, the shearing structure formed by the cutter 4 and the groove wall of the groove body 101 or the water filtering holes 102 can cut these garbage into small sizes, which is convenient for flushing into the sewer, thereby preventing these garbage from clogging the sewer. The above technical solution is the basic technical solution of this application. To further optimize the use effect, other embodiments are also included.

[0051] In some embodiments, a housing 5 is further included. The housing 5 mainly serves a protective function, making the basic structure of the present invention more like a whole. In the basic structure, the filter ring 1 is installed at the water outlet, and the gland 3 arranged above it is connected to the bracket 2 inside it through a movable connection structure. The cutter 4 directly between them is directly exposed, which is relatively dangerous and also inconvenient for use. For example, during the process of rinsing the mop, the cloth strips and thread-like structures on the mop head are easily stuck by the cutter 4 or the groove body 101, or even wrongly cut. Therefore, in this embodiment, the housing 5 is additionally provided. The shape of the housing 5 is a slightly flattened cylinder with upper and lower openings and finally in a tubular shape. Its size is adapted to the sizes of the filter ring 1 and the gland 3. The lower end is exactly aligned with the edge of the filter ring 1 and can be detachably connected by screwing, plugging, etc., or directly fixedly connected by bonding, welding, etc. The upper end of the housing 5 can be used to abut against the lower end of the gland 3. Therefore, the height of the housing 5 can be used to preset the movement range of the gland 3. To ensure that the sewage smoothly flows to the filter ring 1, a plurality of water inlets 501 are opened at the bottom of the side wall of the housing 5. The water inlets 501 are distributed at equal intervals along the circumference of the housing 5. The sewage and garbage pass through the water inlets 501 and flow to the filter ring 1. By providing the housing 5, the internal structure of the device can be isolated from the outside world, effectively protecting the internal structure of the device. At the same time, it prevents the outside world from affecting the shearing work of the cutter 4.

[0052] In some embodiments, in order to further ensure the mating effect between the gland 3 and the housing 5, insertion plates 301 are fixedly arranged at equal intervals on the edge of the lower end of the gland 3. The insertion plates 301 are perpendicular to the lower surface of the gland 3. And slots 502 are formed at positions corresponding to the insertion plates 301 on the upper surface of the side wall of the housing 5. The insertion plates 301 and the slots 502 are in a sliding plug-in relationship. With the presence of the insertion plates 301 and the slots 502, the insertion plates 301 and the slots 502 can be used for positioning and limiting, ensuring that the gland 3 does not deflect circumferentially during the up and down movement, thus affecting the subsequent shearing work. The number of the insertion plates 301 and the slots 502 is not particularly limited, but generally not less than two groups. When the number of the insertion plates 301 and the slots 502 is two groups, they are symmetrically distributed; when the number of the insertion plates 301 and the slots 502 is more than two groups, it only needs to satisfy the law of equal interval distribution. In this embodiment, the number of the insertion plates 301 and the slots 502 is three groups, and they are equally spaced from each other. In addition, the length of the insertion plate 301 is slightly greater than the preset value of the moving distance of the gland 3, because at least it is necessary to ensure that its lowermost end in the initial state has been inserted into the slot 502, and the depth of the slot 502 can be greater than the length of the insertion plate 301, as long as it is ensured that there is no interference with the water inlet 501 below.

[0053] In some embodiments, it further includes guide vanes 503. A plurality of guide vanes 503 are provided and are respectively fixedly installed on the inner side of the side wall of the housing 5, specifically on both side edges in the horizontal direction of the water inlet 501. The first end of the guide vane 503 and the edge of the water inlet 501 are fixedly connected by means such as bonding and welding. The other end faces the axis of the housing 5, and each guide vane 503 is obliquely arranged, specifically referring to being obliquely arranged with respect to the radial direction of the inner ring of the housing 5, and all the guide vanes 503 are inclined in the same direction and at the same inclination angle. Based on this, an inclined flow channel is formed at each water inlet 501 on the housing 5. When sewage enters the device from all directions through the housing 5, after the rectifying effect of these flow channels, it helps to form a vortex. The vortex-shaped water flow can help spread out and intercept garbage such as hair, shredded paper, and plastic sheets on the filter ring 1. The main function is to increase the overlapping area between the garbage and the tank body 101, facilitating cutting. Taking hair as an example, the clustered hair may only overlap at the notch of one tank body 101 or stay at a ridge-shaped protrusion. At this time, when pressing down the pressure cover 3, only the shearing structure formed by one cutter 4 acts on the hair, and at most, the clustered hair is cut into two ends. With the help of the water flow in the vortex, the clustered hair can be driven to spread out. At this time, the hair may be at the notches of multiple tank bodies 101 at the same time. When pressing down the pressure cover 3, the shearing structures formed by multiple cutters 4 will act on the hair simultaneously, and the hair can be cut into multiple segments, with a shorter length and being more convenient to flush into the drain. In addition, the specific shape of the guide vane 503 is not particularly limited. It can be a straight plate shape or have a certain arc. The width of the guide vane 503 can also gradually decrease from the outside to the inside along the radial direction of the housing 5, and the thickness of the guide vane 503 can gradually decrease.

[0054] In some embodiments, a structure is additionally provided that can automatically reset the pressure cover 3. Specifically, a plurality of vertical guide posts 302 are fixed near the center at the lower end of the pressure cover 3. A plurality of positioning collars 201 are provided on the upper end of the bracket 2 corresponding to the plurality of guide posts 302, and a spring 6 is correspondingly provided to connect them. One end of the spring 6 is clamped in the positioning collar 201, and the other end is fixedly sleeved on the guide post 302. When pressing down the pressure cover 3, the spring 6 is also compressed at the same time. When releasing the pressure cover 3, under the action of the elastic potential energy of the spring 6, the pressure cover 3 is pushed upward to achieve the reset effect, further simplifying the operation. It only needs to repeatedly apply and cancel the acting force on the pressure cover 3. The number of the guide posts 302, the positioning collars 201, and the spring 6 is not particularly limited. In this embodiment, there are 4 groups. In addition, the number of the guide posts 302 and the positioning collars 201 can be made of a hard material such as metal or a material with a certain elasticity.

[0055] In some embodiments, a water baffle 7 is further provided, which is mainly used to prevent the multiple springs 6 on the bracket 2 from being corroded by sewage for a long time. The shape of the water baffle 7 is similar to that of the housing 5, both being slightly flattened cylinders with openings at the upper and lower ends, and the whole is cylindrical. Its height is the same as that of the housing 5, and its diameter is smaller than that of the housing 5 and is adapted to the diameter of the bracket 2. It is sleeved on the outside of the multiple springs 6, and its lower end can be detachably connected to the edge of the bracket 2 by means such as screwing and plugging, or can be fixedly connected by means such as welding and bonding. The presence of the water baffle can, to a certain extent, prevent the sewage entering the device from continuing to flow towards the center of the device. Therefore, the bracket 2 and the spring 6 part can be relatively kept dry, especially the spring 6 part.

[0056] To further improve the waterproof effect, a sealing ring groove 340 is fixedly installed at the lower end of the gland 3. The notch of the sealing ring groove 340 faces downward and is aligned with the upper end of the water baffle 7, and at the same time, it maintains a sliding plug-in relationship with the upper end of the water baffle 7. The material of the sealing ring groove 340 is selected from rubber-like materials, which closely fits the side wall of the water baffle 7 to maintain sealing.

[0057] In addition, when the cutting knives 4 adopt the first and third arrangement methods, multiple groups of limiting plates 701 corresponding to and slidably connected to the multiple cutting knives 4 can be fixed on the outer side wall of the water baffle 7. Specifically, each group of limiting plates 701 is composed of two parallel plates, and the distance between the two limiting plates 701 is adapted to the thickness of the cutting knife 4. The two cutting surfaces of the cutting knife 4 are respectively slidably connected to the two limiting plates 701. The presence of the limiting plates 701 can play a limiting role in the cutting knife 4 when it reciprocates with the gland 3 to prevent deviation.

[0058] Specifically, in order to facilitate the installation of the cutting knife 4, the lower end of the gland 3 has multiple installation grooves 303. The installation grooves 303 can be directly opened on the lower surface of the gland 3, or multiple groups of pads can be fixedly welded on the lower surface of the gland 3. Each group of pads has two, and an installation groove 303 is formed between the two pads, as Figure 8 shown, and screw holes are provided on both sides of the installation groove 303. If the installation groove 303 is directly opened on the lower surface of the gland 3, screw holes are continuously opened on the lower surface of the gland 3. If the installation groove 303 is formed by pads, screw holes are opened on the pads.

[0059] Correspondingly, each cutting knife 4 includes an installation part and a blade part 403. The installation part includes an insertion piece 401 and two wing plates 402 located on both sides of the insertion piece 401 and perpendicularly connected thereto. Screw holes are provided on the wing plates 402. The upper end of the insertion piece 401 is used to be inserted into the installation groove 303. The depth of the installation groove 303 can be slightly greater than the length of the insertion piece 401, leaving a gap to prevent errors. After the insertion piece 401 is inserted into the installation groove 303, the plate surface of the wing plate 402 will fit against the lower surface of the gland 3 or the lower surface of the spacer block, and the screw holes on the wing plate 402 are aligned with the screw holes on both sides of the installation groove 303 to complete the bolt connection. Installing the cutting knife 4 in this way is mainly to facilitate subsequent replacement and maintenance work.

[0060] In some embodiments, the ring surface of the filter ring 1 is a slope that slopes downward from the circumferential side towards the axis. On the one hand, such a design facilitates guiding the water flow. On the other hand, the blade part 403 of the cutting knife 4 is also arranged obliquely, and the inclination angle is opposite to the inclination angle of the ring surface of the filter ring 1. Such a design can make the working state of the cutting knife 4 and the water filtering holes 102 or the groove body 101 more similar to that of scissors when forming a shearing structure, improving the actual shearing effect.

[0061] In addition to being used alone, the anti-blocking device for the mop sink provided by the present invention can also be used in cooperation with a rinsing basket 8. The rinsing basket 8 is integrally trapezoidal with an open top, and the bottom is connected to the top of the gland 3. The side wall of the rinsing basket 8 is in a fence shape for water flow, and the inner bottom surface has an upward arc-shaped protrusion. The rinsing basket 8 can further simplify the operation. When the user rinses the mop up and down in the rinsing basket 8 and applies force by contacting the inner bottom of the rinsing basket 8, the action of pressing the gland 3 can be completed and the effect of shearing garbage such as hair and shredded paper can be achieved, as Figure 9 and Figure 10 shown. This is a schematic diagram of the present invention installed in the mop sink, where 100 is the bottom of the mop sink and 200 is the drain pipe.

[0062] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention.
