Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to a detachable and cleanable toilet tank filter device. Background Technology

[0002] Toilets are an indispensable sanitary fixture in modern buildings, mainly consisting of the fixture itself and the water tank. The water tank, as the toilet's flushing system, typically contains an inlet valve (responsible for filling and controlling the water level), a drain valve (responsible for flushing and discharging water), and related lever mechanisms. Its working principle is as follows: when the user operates the flush handle or button, the drain valve opens, using the water stored in the tank to create a siphon effect, flushing away waste and discharging it into the sewage pipe. Therefore, the normal and stable functioning of the water tank directly affects the toilet's flushing effect and user experience.

[0003] Currently, most ordinary toilet tanks on the market are not designed with water filtration functions. Although tap water is purified by water treatment plants, it may carry rust, sediment, limescale particles, and other tiny suspended solids during its transportation through municipal pipe networks, community secondary water supply systems, and old household pipes. If these impurities directly enter the tank, they will cause multiple problems: First, hard particles will wear down the precision sealing gaskets of the inlet and outlet valves, causing them to not close tightly, resulting in continuous "running water" or hidden leaks, wasting water resources and increasing water bills; second, impurities easily accumulate at the bottom of the tank or adhere to components, forming limescale and stains, becoming a breeding ground for bacteria, which is not only unhygienic but also increases the cleaning burden, and cleaning the inside of the tank after impurities enter is relatively troublesome.

[0004] To address this, we propose a detachable and cleanable toilet tank filter. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable and cleanable toilet tank filter device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable and cleanable toilet tank filter device, comprising a housing and a filter assembly. The housing is cylindrical with an open bottom. The bottom surface of the housing is provided with external threads, and a bottom cover is rotatably connected to the bottom surface of the housing via the threads. A convex ring is fixed in the middle of the upper surface of the bottom cover. The filter assembly comprises a cylindrical body with openings at both the top and bottom, with the bottom end of the cylindrical body sleeved on the outside of the convex ring. The top end of the cylindrical body is fitted against the inner top wall of the housing. Several hollow grooves are provided on the side wall of the cylindrical body, and filter cloth is fixed inside the hollow grooves. A water inlet connector is fixed in the tangential direction of the side wall of the housing, a water outlet connector is fixed in the middle of the top wall of the housing, and an installation assembly is fixed at the top of the outer side wall of the housing.

[0007] Furthermore, the water inlet connector is connected to a braided tube via a thread, and the other end of the braided tube is connected to a tap water pipe, while the water outlet connector is connected to the water inlet of the toilet tank.

[0008] Furthermore, a second sealing ring is snapped onto the inner bottom wall side of the bottom cover, and the bottom of the housing is in contact with the second sealing ring.

[0009] Furthermore, annular grooves are provided at both the bottom and top of the cylinder, and a first sealing ring is engaged inside the annular groove. The first sealing ring at the bottom of the cylinder is fitted with the inner bottom wall of the bottom cover, and the first sealing ring at the top of the cylinder is fitted with the inner top wall of the shell.

[0010] Furthermore, the mounting assembly includes a C-shaped plate fixed to the outer wall of the housing, and the bottom wall of the C-shaped plate is provided with an arc-shaped groove. The top wall of the C-shaped plate is through which a screw is rotatably connected. The bottom end of the screw is rotatably connected to a pressure plate through a bearing. The top end of the screw is fixedly connected to a knob. Rubber pads are fixed to the lower surface of the pressure plate and the inner wall of the arc-shaped groove.

[0011] Furthermore, the inner wall of the C-shaped plate is provided with a sliding groove, and one end of the pressure plate is located inside the sliding groove and is slidably connected to the sliding groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model includes a housing, a bottom cover, a filter assembly, an inlet connector, an outlet connector, and an installation assembly. Water enters the housing through the inlet connector on the tangent of the side wall of the housing. The water flow rotates inside the housing, passes through the filter assembly, and is discharged from the outlet connector, finally entering the toilet tank. The filter assembly can filter out impurities such as mud, rust, and scale particles. Furthermore, because the water flow rotates inside the housing, impurities are prevented from adsorbing onto the filter cloth surface of the filter assembly, reducing the probability of clogging.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a detachable and cleanable toilet tank filter device is disclosed, comprising a housing 1 and a filter assembly 3. The housing 1 is cylindrical and has an open bottom. The bottom surface of the housing 1 is provided with external threads, and a bottom cover 2 is rotatably connected to the bottom surface of the housing 1 via the threads. A protruding ring 4 is fixed in the middle of the upper surface of the bottom cover 2. The filter assembly 3 includes a cylindrical body 31 with openings at both the top and bottom. The bottom end of the cylindrical body 31 is sleeved on the outside of the protruding ring 4, and the top end of the cylindrical body 31 is fitted with the inner top wall of the housing 1. Several hollow grooves 32 are opened on the side wall of the cylindrical body 31, and filter cloth 33 is fixed inside the hollow grooves 32. A water inlet connector 6 is fixed in the tangential direction of the side wall of the housing 1, a water outlet connector 7 is fixed in the middle of the top wall of the housing 1, and an installation assembly 9 is fixed in the top of the outer side wall of the housing 1.

[0024] In this embodiment, the filter cloth 33 is flush with the surface of the cylinder 31, which facilitates the cleaning of impurities on the surface of the filter cloth 33 after the filter assembly 3 is disassembled.

[0025] The device is installed between the tap water pipe and the inlet of the toilet tank. The existing technology uses a braided hose for connection.

[0026] In this embodiment, the inlet connector 6 is threadedly connected to a braided tube 8, and the other end of the braided tube 8 is connected to a tap water pipe. The braided tube 8 on the toilet tank inlet is threadedly connected to the outlet connector 7. The connection method here is exactly the same as the existing braided tube 8 installation method.

[0027] The bottom wall of the bottom cover 2 is fitted with a second sealing ring 5, and the bottom of the housing 1 is in contact with the second sealing ring 5.

[0028] When the bottom cover 2 is screwed onto the bottom surface of the housing 1, the second sealing ring 5 can ensure the sealing between the housing 1 and the bottom cover 2.

[0029] Both the bottom and top ends of the cylinder 31 are provided with annular grooves, and a first sealing ring 34 is engaged inside the annular groove. The first sealing ring 34 at the bottom of the cylinder 31 fits against the inner bottom wall of the bottom cover 2, and the first sealing ring 34 at the top of the cylinder 31 fits against the inner top wall of the shell 1.

[0030] During the initial assembly of the filter assembly 3, the bottom end of the cylinder 31 is first fitted onto the surface of the convex ring 4. Then, the cylinder 31 is inserted into the interior of the housing 1 from the bottom. Subsequently, the bottom cover 2 is screwed onto the bottom surface of the housing 1. The cylinder 31 is then pressed and fixed by the inner top wall of the housing 1 and the bottom cover 2. At this time, the first sealing ring 34 can ensure the sealing between the cylinder 31 and the bottom cover 2, and the inner top wall of the housing 1. Water from the tap pipe enters the interior of the housing 1 through the inlet connector 6 and can only pass through the filter cloth 33 on the side wall of the cylinder 31 before being discharged from the outlet connector 7.

[0031] Mounting assembly 9 includes a C-shaped plate 91 fixed to the outer wall of housing 1, and the bottom wall of the C-shaped plate 91 is provided with an arc groove 92. The top wall of the C-shaped plate 91 is through which a screw 93 is rotatably connected by a thread. The bottom end of the screw 93 is rotatably connected to a pressure plate 94 through a bearing. The top end of the screw 93 is fixedly connected to a knob 95. Rubber pads are fixed on the lower surface of the pressure plate 94 and the inner wall of the arc groove 92.

[0032] In addition to connecting the device to the water pipe and water tank, it is also necessary to fix the device. When fixing, first, the C-shaped plate 91 is clamped onto the surface of the water pipe, so that the water pipe is clamped inside the arc groove 92. Then, the knob 95 is turned to drive the screw 93 and the pressure plate 94 to descend. The pressure plate 94 is used to squeeze the water pipe to fix the installation component 9 to the water pipe. The rubber pad can protect the surface of the water pipe and increase the friction, thereby improving the stability of the fixation. Here, the arc groove 92 is in surface contact with the water pipe, which can ensure the stability of the installation. The screw 93 is a self-locking screw 93.

[0033] A groove 96 is provided on the inner side wall of the C-shaped plate 91. One end of the pressure plate 94 is located inside the groove 96 and is slidably connected to the groove 96. When the screw 93 drives the pressure plate 94 to move, the pressure plate 94 can only press against the groove 96 to move, preventing the pressure plate 94 from rotating.

[0034] Working principle: First, the device is fixed in position by connecting the installation component 9 to the water supply pipe. Then, the braided tube 8 on the inlet connector 6 is connected to the water supply pipe connector. Finally, the braided tube 8 on the toilet tank is connected to the outlet connector 7.

[0035] During normal use, after the valve inside the toilet tank is opened, water enters the interior of the housing 1 along the tangential direction of the housing 1, and then passes through the filter cloth 33 and enters the interior of the tank from the water outlet 7. The filter cloth 33 filters out impurities in the water, and because the water flow rotates inside the housing 1, the friction between the water flow and the surface of the filter cloth 33 makes it difficult for impurities to adhere to the surface of the filter cloth 33, thereby avoiding blockage. Finally, the impurities fall into the bottom cover 2 under the action of gravity.

[0036] During cleaning, unscrew the bottom cover 2 from the bottom of the housing 1 and pull out the filter assembly 3 to clean or replace it entirely.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
