Referring to fig. 1-11, an embodiment of the present invention provides a filter device, which includes an installation cylinder 1, an installation cover 2, and a filter element assembly 3; the mounting cylinder 1 is hollow inside, and the top of the mounting cylinder 1 is provided with a first open mouth; the mounting cover 2 is connected to the first opening, and the mounting cover 2 is provided with a water inlet channel 21 and a water outlet channel 22 which are communicated with the inside of the mounting cylinder 1; the filter element assembly 3 is arranged in the installation cylinder 1, the filter element assembly 3 comprises a filter element cylinder 31 and a filter screen cylinder 32 sleeved on the filter element cylinder 31, the filter element cylinder 31 is hollow inside, two ends of the filter element cylinder 31 are sealed structures, a filter material is arranged in the filter element cylinder 31, the filter material is a commonly used filter material, such as sponge or a porous ceramic rod, and the like, a first hollow part 311 is arranged on the side wall of the filter element cylinder 31, a water outlet nozzle 312 communicated with the inside of the filter element cylinder 31 is formed in a protruding mode at the top of the outer wall of the filter element cylinder 31, and the water outlet nozzle 312 is arranged in the water outlet channel 22 in a penetrating mode; the protruding a plurality of protruding muscle 313 that are formed with of inner wall top of filter core section of thick bamboo 31, the both ends of protruding muscle 313 are connected to the bottom opening edge of faucet 312 and the inside wall of filter core section of thick bamboo 31 respectively, and the height dimension of protruding muscle 313 diminishes gradually in the direction of the bottom opening edge of faucet 312 from the inside wall of filter core section of thick bamboo 31, and the position department that is close to protruding muscle 313 in the filter core section of thick bamboo 31 installs first filter screen piece 4.
It can be understood that the tap water firstly enters the installation cylinder 1 from the water inlet channel 21, then enters the filter element cylinder 31 through the first hollow part 311 after being primarily filtered by the filter element cylinder 32, then is secondarily filtered by the filter material in the filter element cylinder 31, and finally flows into the water outlet channel 22 from the water outlet nozzle 312 after being filtered by the first filter element 4, so that the tap water is filtered and purified. The filter screen cylinder 32 and the first filter screen sheet 4 are both of the conventional common filter screen structure, and are made of stainless steel, for example, and have the function of filtering large-particle impurities such as silt, rust, ova, red worms and the like in water.
A plurality of ribs 313 may be circumferentially disposed along the bottom opening edge of the spout 312. The ribs 313 may be formed by a plurality of intermittent bumps.
Based on above-mentioned technical scheme, a plurality of protruding muscle 313 with the relative interval of inner wall top of first filter screen piece 4 and filter screen section of thick bamboo 32 in order to form hollow out construction, simultaneously protruding muscle 313's height dimension diminishes gradually in the direction of the bottom opening edge of faucet 312 from the inside wall of filter element section of thick bamboo 31, make this hollow out construction be hourglass hopper-shaped, filterable water passes through first filter screen piece 4 in proper order, hollow out construction and faucet 312 flow in outlet channel 22, when rivers were through hollow out construction, because hollow out construction is hourglass hopper-shaped, lead to the cross sectional area of rivers littleer and smaller, thereby increased the water flow velocity in order to improve outlet channel 22's the discharge, in order to satisfy the user demand of water heater (for example gas heater), also promote user's shower experience simultaneously and feel.
Specifically, because the hollow out construction between the inner wall top of first filter screen piece 4 and filter screen cylinder 32 is hourglass hopper-shaped, hollow out construction's cross sectional area diminishes gradually from first filter screen piece 4 towards faucet 312's direction, according to the velocity of flow formula: when the same flow passes through the hollow structure, the cross-sectional area is reduced, and the flow velocity is increased, so that the flow velocity of the water outlet nozzle 312 is increased, and the water yield of the water outlet channel 22 is increased.
In some embodiments, in order to improve the installation stability of the first screen sheet 4 in the filter element cylinder 31, an installation step 314 is formed on the inner side wall of the filter element cylinder 31 near the rib 313, and the first screen sheet 4 is welded on the installation step 314. For example, the first screen sheet 4 is welded to the mounting step 314 by ultrasonic welding, so that the connection is stable and is difficult to loosen, and the use stability is improved.
In some embodiments, in order to improve the filtering efficiency, the bottom of the filter element cylinder 31 is opened with a second open port, the second open port is connected with the bottom cover 5 in a sealing manner, and the bottom cover 5 is opened with a second hollow part 51. The water in the installation cylinder 1 can directly enter the filter element cylinder 31 through the second hollow part 51 to be filtered by the filter material, so that the filtering efficiency is further improved.
In some embodiments, the filtration device of the present invention further comprises a second screen sheet 6, the second screen sheet 6 being mounted on the bottom cover 5 and covering the second hollowed-out portion 51. For example, the second filter screen sheet 6 is welded to the outer side of the bottom cover 5 by ultrasonic welding technology, so that the connection is stable and is difficult to loosen, and the use stability is improved.
Further, in order to clean the dirt on the first filter screen piece 4, the second filter screen piece 6 or the filter screen cylinder 32 conveniently, the bottom of the mounting cylinder 1 is provided with a sewage discharge hole 12. When dirt on the first filter screen piece 4 or the second filter screen piece 6 or the filter screen cylinder 32 needs to be cleaned, tap water flows in from the water outlet channel 22, the water inlet channel 31 is closed at the moment, and water washes the first filter screen piece 4, the second filter screen piece 6 and the filter screen cylinder 32 under the action of gravity, so that the cleaning purpose is achieved, the trouble of detaching and cleaning the first filter screen piece 4 or the second filter screen piece 6 or the filter screen cylinder 32 is avoided, and the use convenience is improved. In addition, the drainage hole 12 may be sealed off with a sealing member, such as a threaded fastener, when the filter device is in normal use.
In some embodiments, the bottom of the inner wall of the mounting cylinder 1 is provided with a limiting protrusion 11 abutting against the bottom of the filter element cylinder 31. The number of the limiting protrusions 11 can be multiple, and the limiting protrusions 11 are arranged along the circumferential direction of the installation cylinder 1 at intervals. After the filter element assembly 3 is installed in the installation cylinder 1, the limiting bulge 11 is abutted to the bottom of the filter element cylinder 31, and the purpose of installation and positioning is achieved.
In some embodiments, a first sealing ring 7 is provided between the filter element cylinder 31 and the filter screen cylinder 32. For example, the number of the first sealing rings 7 is two, and the two ends of the filter element cylinder 31 are sleeved with the two first sealing rings 7, so that the sleeving stability between the filter element cylinder 31 and the filter screen cylinder 32 is improved, the water sealing effect is better, and water leakage is prevented.
In some embodiments, the spout 312 is fitted with a second sealing ring 8. The second sealing ring 8 is used for filling a gap between the water outlet nozzle 312 and the water outlet channel 22, and plays a role in waterproof sealing.
