Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, in particular to a box-type reverse osmosis water purifier. Background Art

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to the requirements for water use. Currently, most water purifiers on the market are multi-stage filter cartridges, which usually include multiple filter cartridges connected in series, such as: PP cotton filter cartridges, activated carbon filter cartridges, RO membrane filter cartridges and post-activated carbon column filter cartridges. Among them, the PP cotton filter cartridges filter suspended particles, mud and other large particle impurities, protecting subsequent filter cartridges from clogging. The porous structure of activated carbon absorbs chlorine, odor, organic compounds and some heavy metals in the water, improving the taste and smell of the water. The RO membrane (pore size 0.0001 microns) only allows water molecules and extremely small ions to pass through, intercepting more than 99% of bacteria, viruses, heavy metals (such as mercury and arsenic) and soluble inorganic salts.

[0003] Patent document CN108031290B discloses a water purifier, comprising: an integrated waterway plate, wherein a waterway is integrated inside the integrated waterway plate, and the installation area of the integrated waterway plate comprises a front installation area and a back installation area located oppositely on both sides of the integrated waterway plate; a water production module, wherein the water production module is arranged in the front installation area of the integrated waterway plate, and the water production module comprises at least one filter element, which is connected to the waterway of the integrated waterway plate; compared with the prior art in which the water production module and the electronic control module are staggered, this application greatly reduces the number of pipeline connection points, thereby improving the sealing of the pipeline in the water purifier and reducing the risk of water leakage in the water purifier.

[0004] However, in addition to the fact that there are many pipe connection points in the water purifier, which leads to the sealing problem of the pipe connections in the water purification equipment being not tight, during the pressurized filtration process in the filter bottle, water seepage will occur between the filter bottle and the cap due to the high pressure. In addition, when the air pressure in the filter bottle is too high, the cap is difficult to unscrew and the filter element is difficult to replace. The traditional method is to release the pressure by opening the water purification faucet and disassembling the pipe to release the remaining pressure, but water is easily retained in the pipe, causing water to drip at will, and the disassembly and assembly process is not only troublesome, but also easy for bacteria to enter the pipe and contaminate the purified water. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a box-type reverse osmosis water purifier, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a box-type reverse osmosis water purifier, comprising a body and a filter bottle fixedly mounted on the body, the filter bottle being threadedly connected to a sealing cap, and further comprising: A pressure relief plug, which is threadedly connected to the middle of the sealing cap and is used to release the residual air pressure inside the filter bottle; The inner sealing assembly includes a mounting plate movably mounted on the outer surface of the pressure relief plug, and a first sealing skirt fixedly mounted on the upper surface of the mounting plate. The cover is provided with a driving mechanism. When the pressure relief plug is turned downward, the driving mechanism passively presses the first sealing skirt to seal the interface between the filter bottle and the cover.

[0009] Preferably, the cross section of the mounting plate is concave, and the pressing piece is an arc-shaped right-angle piece adapted to one end thereof.

[0010] Preferably, it also includes a docking assembly, which is located below the mounting plate and includes an inner docking module and an outer docking module. The inner docking module includes a positioning member and a second sealing skirt opened on the top of the positioning member. An extension member is provided at the upper end of the second sealing skirt, and a first card slot is provided at the bottom of the mounting plate.

[0011] Preferably, the external docking module includes a second slot provided in the middle of the positioning member, and a rubber ring is provided in the second slot.

[0015] Preferably, the outer surface of the sealing cover is provided with a tooth groove, and the clamping piece is located at the gap between the sealing cover and the outer interface of the filter bottle.

[0016] The present invention provides a box-type reverse osmosis water purifier, which has the following beneficial effects: by arranging a pressure relief plug on the top of the cover, it is avoided that the pressure relief caused by disassembling the pipeline causes bacteria to enter the pipeline and cause water pollution; in addition, one end of the driven rod can be passively pressed down, so that the end of the driven rod fixed with the clamping piece is tilted upward, and the first sealing skirt is compressed, thereby sealing the internal connection between the filter bottle and the cover, thereby improving the sealing performance of the filter bottle of the water purifier.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1: Please refer to Figures 1 to 6 The present invention provides a technical solution: a box-type reverse osmosis water purifier, comprising a body 1 and a filter bottle 11 fixedly mounted on the body 1, a sealing cap 12 being threadedly connected to the filter bottle 11, and further comprising: The pressure relief plug 2 is threadedly connected to the middle of the sealing cover 12 and is used to release the residual air pressure inside the filter bottle 11; The inner sealing assembly includes a mounting plate 3 movably mounted on the outer surface of the pressure relief plug 2, and a first sealing skirt 31 fixedly mounted on the upper surface of the mounting plate 3. A driving mechanism is provided on the cover 12. When the pressure relief plug 2 is turned downward, the driving mechanism passively presses the first sealing skirt 31 to seal the interface between the filter bottle 11 and the cover 12.

[0021] A pressure relief hole is provided on the sealing cover 12 , and the pressure relief plug 2 is threadedly connected to the pressure relief hole. The upper end diameter of the pressure relief plug 2 is larger than the lower end diameter.

[0022] The driving mechanism includes a mounting member 32 fixedly mounted on the top of the inner cavity of the cover 12 and a driven rod 33 movably mounted on the mounting member 32. A pressing member 34 is fixedly mounted on one end of the driven rod 33, and a driving block 35 is fixedly mounted on the outer surface of the pressure relief plug 2.

[0023] The cross section of the mounting plate 3 is concave, and the pressing member 34 is an arc-shaped right-angle member adapted to one end thereof.

[0024] When replacing the filter element, the traditional method is to first release the water pressure by opening the water purification tap, and then disconnect the pipe connected to the filter bottle to release the remaining pressure. However, water is likely to remain in the pipe, causing water to drip randomly. The disassembly and assembly process is not only troublesome, but also easy for bacteria to enter the pipe. Specifically, after the water is released from the faucet and the pressure is released, the pressure relief plug 2 can be turned upward to separate the end with the larger diameter of the pressure relief plug 2 from the pressure relief hole, as shown in the attached figure. Figure 5 As shown in a, the excess air pressure in the filter bottle 11 can be released through the pressure relief hole, so there is no need to disassemble the pipeline or the cover 12 to release the air pressure, thereby improving the efficiency of filter element replacement; Furthermore, when the filter element is replaced, it is necessary to turn the pressure relief plug 2 downward to block the pressure relief hole at the portion with a larger diameter at the upper end of the pressure relief plug 2, thereby avoiding the problem of air pressure leakage during the use of the water purifier. A sealing ring can also be provided at a of the pressure relief plug 2 to improve the sealing performance. When the pressure relief plug 2 moves downward, it drives the driving block 35 to move downward. When the driving block 35 moves downward, it presses down one end of the driven rod 33, so that the end of the driven rod 33 fixed with the pressing piece 34 is tilted upward, thereby pressing the first sealing skirt 31, thereby sealing the internal connection between the filter bottle 11 and the cover 12, and avoiding excessive air pressure in the filter bottle 11, which causes water to leak from the internal connection between the filter bottle 11 and the cover 12; Compared with the existing technology, by setting a pressure relief plug 2 on the top of the cover 12, it is possible to avoid disassembling the pipeline to release pressure, which may cause bacteria to enter the pipeline and cause water pollution. In addition, the internal connection between the filter bottle 11 and the cover 12 can be passively sealed to improve the sealing performance of the filter bottle 11.

[0025] Example 2: Please refer to Figures 3 to 7, also includes a docking assembly, which is located below the mounting plate 3 and includes an inner docking module and an outer docking module. The inner docking module includes a positioning member 4 and a second sealing skirt 42 opened on the top of the positioning member 4. An extension member 43 is provided at the upper end of the second sealing skirt 42, and a first card slot 45 is opened at the bottom of the mounting plate 3.

[0026] The external docking module includes a second slot 46 formed in the middle of the positioning member 4 , and a rubber ring is disposed in the second slot 46 .

[0027] Specifically, when replacing the filter element, for the PP cotton filter element, the filter element is directly placed into the filter bottle, and then the cover is tightened, but the interface on the top of the cover inner cavity needs to be inserted into the top inner cavity of the PP cotton filter element to prevent the clean water from overflowing while positioning. In the present invention, when installing the PP cotton filter element, it is first placed in the filter bottle 11 so that the positioning member 4 is inserted into the top inner cavity of the PP cotton filter element, and then the PP cotton filter element is limited by the first card slot 45 that is adapted to the size of the PP cotton filter element to assist the installation of the PP cotton filter element and avoid its tilting, which leads to the problem of uneven filtration. Then, based on Example 1, when the pressure relief plug 2 is turned downward, one end of the driven rod 33 is pressed down by the driving block 35 and is connected with the mounting plate 3 The extension piece 43 is fixedly mounted on the upper surface of the positioning member 4, and the mounting plate 3 is moved downward until it contacts the upper surface of the positioning member 4. The driving column 44 is also fixedly mounted on the upper surface of the extension piece 43. When the mounting plate 3 descends to contact the upper surface of the positioning member 4, it will first contact the screw hole 41 and drive the screw hole 41 to move downward, so that the extension piece 43 moves downward. The cross-section of the extension piece 43 is a trapezoidal shape with a wide upper part and a narrow lower part. When the extension piece 43 moves downward and enters the middle of the second sealing skirt 42, it squeezes both sides of the second sealing skirt 42, so that the outer skirt is in close contact with the inner wall of the PP cotton filter element. On the one hand, it can fix the PP cotton filter element, and on the other hand, it can improve the sealing performance of the PP cotton filter element to prevent the internal clean water and the external concentrated water from mixing. Furthermore, for the PO membrane filter element, when installing, it is first necessary to install the stopper adapted thereto on the end of the PO membrane filter element without the rubber ring. After the installation is completed, it is necessary to install the end of the PO membrane filter element with the rubber ring downward into the filter bottle 11 so that the end with the stopper is facing upward, and then the knob cover 12 is turned to make the stopper enter the second slot 46 to complete the fixation of the PO membrane filter element. Similarly, under the action of the extension piece 43, the inner skirt will clamp the stopper on the PO membrane filter element, further improving the stability of the PO membrane filter element. The fixing method between the second sealing skirt 42 and the extension piece 43 can be adopted according to the actual situation. Adhesion or melting or the like can be adopted. In this way, the extension piece 43 can be fixed while being expanded under the deformation of the extension piece 43 to achieve the purpose of sealing. More specifically, a screw hole 41 is provided on the top of the upper surface of the positioning member 4, which is adapted to the bottom of the pressure relief plug 2, so that the user can easily disassemble and replace the positioning member 4. The pressure relief plug 2 passes through the cover 12. Except for point a, there is a distance between the pressure relief plug 2 and the cover 12. Correspondingly, there is also a distance between the mounting plate 3 and the inner cavity wall of the filter bottle 11, which facilitates gas flow and releases air pressure.

[0028] Example 3: Please refer to Figure 3 、 Figure 5 and Figure 8 , and also includes a fastening assembly, which includes a driving space 5 opened inside the cover 12, and a wedge 52 in the driving space 5, one end of the wedge 52 is fixedly installed with a connecting frame 53, and the other end of the connecting frame 53 is fixedly installed with a clamping member 54.

[0029] One end of the wedge-shaped member 52 is fixedly connected to the elastic column 51 , and the other end of the elastic column 51 is fixedly connected to the cover 12 .

[0030] A driving cover 55 is fixedly mounted on the outer surface of the pressure relief plug 2 , and the inclined surface of the wedge-shaped piece 52 faces the outside of the sealing cover 12 .

[0031] The outer surface of the sealing cover 12 is provided with tooth grooves, and the clamping member 54 is located at the gap between the sealing cover 12 and the outer interface of the filter bottle 11.

[0032] Specifically, on the basis of Example 1, when the pressure relief plug 2 is turned downward, the driving cover 55 will be driven to move downward in the driving space 5, so that the driving cover 55 will squeeze the inclined surface of the wedge 52, thereby causing the wedge 52 to move. At this time, the elastic column 51 is stretched and deformed. When the wedge 52 moves toward the pressure relief plug 2, it will drive the connecting frame 53 to move, so that the clamping member 54 follows and moves until it contacts the gap between the filter bottle 11 and the outer interface of the cover 12. The cross-sectional shape of the clamping member 54 is L-shaped, which is adapted to the outer interface of the filter bottle 11 and the cover 12. By clamping the filter bottle 11 and the cover 12, it can avoid the high internal pressure of the filter bottle 11 and the air pressure squeezing the inner peripheral side of the cover 12, causing the cover 12 to expand and cause the cover 12 to rupture. As a preferred option, a convex ring can also be fixed on the outer peripheral side of the filter bottle 11, as shown in the attached manual. Figure 4 As shown in b, when the clamping member 54 is clamped, the outwardly protruding portion of its bottom is above the convex ring. When the air pressure in the filter bottle 11 presses the sealing cover 12 upward, the convex ring interferes with the clamping member 54 to position the clamping member 54. Since the clamping member 54 is arranged on the sealing cover 12, the sealing cover 12 is positioned and prevented from being separated from the filter bottle 11, thereby reducing the risk of bottle explosion. On the other hand, when unscrewing the cover 12, the knob is usually turned with a corresponding wrench, but the wrench and the water purifier are separate entities. During use, people often lose the wrench, which makes it difficult to unscrew the cover 12. In the present invention, after the pressure is released, the drive cover 55 no longer limits the wedge 52. At this time, the elastic force generated during the elastic deformation of the elastic column 51 will drive the wedge 52 to reset, thereby causing the connecting frame 53 to follow the reset. At this time, there is a distance between the connecting frame 53 and the cover 12, and the number of connecting frames 53 is greater than one. By holding the two connecting frames 53 and using them as handles, the cover 12 can be unscrewed, thereby improving the practicality of the present invention.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
