Description

Technical Field

[0001] This invention relates to the field of water purifier technology, specifically a box-type reverse osmosis water purifier. Background Technology

[0002] A water purifier, also called a water purification machine or water quality purifier, is a water treatment device that performs deep filtration and purification of water according to the requirements of water use. Most water purifiers on the market are multi-stage filter purifiers, which usually include multiple filter cartridges connected in series, such as: PP cotton filter cartridge, activated carbon filter cartridge, RO membrane filter cartridge, and post-activated carbon column filter cartridge. Among them, the PP cotton filter cartridge filters suspended particles, sediment and other large particulate impurities, protecting the subsequent filter cartridges from clogging. The porous structure of activated carbon adsorbs chlorine, odors, 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, and intercepts more than 99% of bacteria, viruses, heavy metals (such as mercury and arsenic) and dissolved inorganic salts.

[0003] Patent document CN108031290B discloses a water purifier, comprising: an integrated water circuit board, wherein the integrated water circuit board has an integrated water circuit, and the installation area of ​​the integrated water circuit board includes a front installation area and a back installation area located opposite each other on both sides of the integrated water circuit board; a water production module, wherein the water production module is disposed in the front installation area of ​​the integrated water circuit board, and the water production module includes at least one filter element, the filter element being connected to the water circuit of the integrated water circuit board; compared with the prior art, which alternates the water production module and the electrical control module, this application greatly reduces the number of pipe connection points, thereby improving the sealing performance of the pipes in the water purifier and reducing the risk of water leakage.

[0004] However, besides the sealing problem caused by numerous pipe connection points in water purifiers leading to poor sealing of the pipe connections, water purifiers also experience leakage between the filter bottle and the cap due to the high pressure during the pressurized filtration process. In addition, when the air pressure inside the filter bottle is too high, the cap is difficult to unscrew, making filter replacement difficult. The traditional method is to open the water faucet to release water and disassemble the pipes to release the remaining pressure. However, water is easily left in the pipes, causing water to drip randomly. Moreover, the disassembly and assembly process is not only troublesome, but it can also easily allow bacteria to enter the pipes and contaminate the purified water. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a box-type reverse osmosis water purifier, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a box-type reverse osmosis water purifier, comprising a body and a filter bottle fixedly mounted on the body, wherein the filter bottle is threadedly connected to a cap, and further comprising:

[0007] A pressure relief plug, threadedly connected to the middle of the cap, is used to release residual gas pressure inside the filter bottle;

[0008] 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 cap is provided with a driving mechanism. When the pressure relief plug is turned downwards, the driving mechanism passively presses the first sealing skirt to seal the interface between the filter bottle and the cap.

[0009] Preferably, the cover has a pressure relief hole, and the pressure relief plug is threaded into the pressure relief hole, wherein the upper diameter of the pressure relief plug is larger than the lower diameter.

[0010] Preferably, the driving mechanism includes a mounting component fixedly installed on the top of the inner cavity of the cover, and a driven rod movably installed on the mounting component. One end of the driven rod is fixedly installed with a clamping component, and a driving block is fixedly installed on the outer surface of the pressure relief plug.

[0011] Preferably, the cross-section of the mounting plate is concave, and the clamping member is an arc-shaped right-angle member that is adapted to one end of the plate.

[0012] Preferably, it also includes a docking component located below the mounting plate. The docking component includes an inner docking module and an outer docking module. The inner docking module includes a positioning element and a second sealing skirt formed on the top of the positioning element. An extension element is provided at the upper end of the second sealing skirt. A first slot is formed at the bottom of the mounting plate.

[0013] Preferably, the external docking module includes a second slot formed in the middle of the positioning member, and a rubber ring is provided in the second slot.

[0014] Preferably, it also includes a fastening assembly, which includes a drive space opened inside the cover and a wedge-shaped member located in the drive space. One end of the wedge-shaped member is fixedly mounted with a connecting frame, and the other end of the connecting frame is fixedly mounted with a clamping member.

[0015] Preferably, one end of the wedge-shaped member is fixedly connected to an elastic column, and the other end of the elastic column is fixedly connected to the cover.

[0016] Preferably, a drive cover is fixedly installed on the outer surface of the pressure relief plug, and the inclined surface of the wedge-shaped member faces the outside of the cover.

[0017] Preferably, the outer surface of the cap is provided with a toothed groove, and the clamping member is located at the gap between the cap and the outer interface of the filter bottle.

[0018] This invention provides a box-type reverse osmosis water purifier with the following advantages: by setting a pressure relief plug on the top of the cap, bacteria are prevented from entering the pipes and contaminating the water due to pressure relief caused by disassembling the pipes. In addition, one end of the driven rod can be passively pressed down, causing the end of the driven rod with the clamping member to tilt upwards and press the first sealing skirt, thereby sealing the inner connection between the filter bottle and the cap and improving the sealing performance of the water purifier filter bottle.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1: Please refer to Figures 1 to 6The present invention provides a technical solution: a box-type reverse osmosis water purifier, comprising a body 1 and a filter bottle 11 fixedly installed on the body 1, wherein a cap 12 is threadedly connected to the filter bottle 11, and further comprising:

[0030] Pressure relief plug 2 is threaded into the middle of the cap 12 and is used to release residual air pressure inside the filter bottle 11.

[0031] 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. The cover 12 is provided with a driving mechanism. When the pressure relief plug 2 is turned down, the driving mechanism passively presses the first sealing skirt 31 to seal the interface between the filter bottle 11 and the cover 12.

[0032] The cover 12 has a pressure relief hole, and the pressure relief plug 2 is threaded into the pressure relief hole. The upper diameter of the pressure relief plug 2 is larger than the lower diameter.

[0033] The drive mechanism includes a mounting member 32 fixedly installed on the top of the inner cavity of the cover 12, and a driven rod 33 movably installed on the mounting member 32. A clamping member 34 is fixedly installed at one end of the driven rod 33, and a drive block 35 is fixedly installed on the outer surface of the pressure relief plug 2.

[0034] The mounting plate 3 has a concave cross-section, and the clamping member 34 is an arc-shaped right-angle member that fits one end of it.

[0035] When replacing the filter cartridge, the traditional method is to first open the water faucet to release water and then disconnect the pipe connected to the filter bottle to release the remaining pressure. However, water is easily left in the pipe, causing water to drip randomly. In addition, the disassembly and assembly process is not only troublesome, but also makes it easy for bacteria to enter the pipe.

[0036] Specifically, after releasing pressure by draining water from the water purifier faucet, the pressure relief plug 2 can be turned upwards to disengage the larger diameter end of the plug from the pressure relief hole, as shown in the attached diagram. Figure 5 As shown at point a, excess air pressure inside filter bottle 11 can be released through the pressure relief hole, thus eliminating the need to disassemble the pipeline or cover 12 to release air pressure and improving filter replacement efficiency.

[0037] Furthermore, after the filter element is replaced, the pressure relief plug 2 needs to be turned downwards to seal the pressure relief hole at the larger diameter part of the upper end of the pressure relief plug 2, so as to avoid the problem of air pressure leakage during the use of the water purifier. A sealing ring can also be set at point a of the pressure relief plug 2 to improve the sealing performance. When the pressure relief plug 2 moves downwards, it will drive the drive block 35 to move downwards as well. When the drive block 35 moves downwards, it will press down on one end of the driven rod 33, so that the end of the driven rod 33 with the clamping part 34 fixed on it will be lifted upwards, thereby pressing the first sealing skirt 31, thus sealing the inner connection between the filter bottle 11 and the cap 12, preventing the air pressure in the filter bottle 11 from being too high, which would cause water to leak from the inner connection between the filter bottle 11 and the cap 12.

[0038] Compared to existing technologies, by setting a pressure relief plug 2 on the top of the cap 12, it is possible to avoid bacteria entering the pipeline due to disassembly and pressure relief, which would contaminate the water. In addition, it can passively seal the inner connection between the filter bottle 11 and the cap 12, thereby improving the sealing performance of the filter bottle 11.

[0039] Example 2: Please refer to Figures 3 to 7 It also includes a docking component located below the mounting plate 3. The docking component includes an inner docking module and an outer docking module. The inner docking module includes a positioning element 4 and a second sealing skirt 42 opened on the top of the positioning element 4. An extension element 43 is provided at the upper end of the second sealing skirt 42. A first slot 45 is opened at the bottom of the mounting plate 3.

[0040] The external docking module includes a second slot 46 located in the middle of the positioning member 4, and a rubber ring is provided in the second slot 46.

[0041] 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 cap is tightened. However, the interface at the top of the cap's inner cavity needs to be inserted into the top inner cavity of the PP cotton filter element to position it and prevent water from overflowing. In this invention, when installing the PP cotton filter element, it is first placed into the filter bottle 11, so that the positioning piece 4 is inserted into the top inner cavity of the PP cotton filter element. Then, the PP cotton filter element is limited by the first slot 45 that matches the size of the PP cotton filter element, which helps to install the PP cotton filter element and prevents it from tilting, which would cause uneven filtration. Then, based on Example 1, when the pressure relief plug 2 is turned downwards, one end of the driven rod 33 is pressed down by the drive block 35 and connects with the mounting plate 3. The mounting plate 3 moves downward until it contacts the upper surface of the positioning member 4. The upper surface of the extension member 43 is also fixedly mounted with a drive column 44. 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, causing the extension member 43 to move downward. The cross section of the extension member 43 is a trapezoid with a wider top and a narrower bottom. When the extension member 43 moves downward into the middle of the second sealing skirt 42, it will squeeze the two 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 and prevent the internal clean water and external concentrated water from mixing.

[0042] Furthermore, for PO membrane filter elements, during installation, the matching stop head should first be installed on the end of the PO membrane filter element without the rubber ring. After installation, the end of the PO membrane filter element with the rubber ring should be installed downwards into the filter bottle 11, so that the end with the stop head is facing upwards. Then, turn the knob to seal the cap 12 so that the stop head enters the second slot 46, thus completing the fixation of the PO membrane filter element. Similarly, under the action of the extension member 43, the inner skirt will clamp the stop head 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 member 43 can be adhesive or fusion, etc., depending on the actual situation. In this way, the extension member 43 can be fixed while also expanding under the deformation of the extension member 43 to achieve the purpose of sealing.

[0043] More specifically, the top of the upper surface of the positioning component 4 is provided with a screw hole 41 that matches the bottom of the pressure relief plug 2, which makes it easy for the user to disassemble and replace the positioning component 4. The pressure relief plug 2 penetrates the cover 12. Except for point a, there is a gap between the pressure relief plug 2 and the cover 12. Correspondingly, there is also a gap between the mounting plate 3 and the inner wall of the filter bottle 11, which facilitates gas flow and releases gas pressure.

[0044] Example 3: Please refer to Figure 3 , Figure 5 and Figure 8It also includes a fastening assembly, which includes a drive space 5 opened inside the cover 12 and a wedge 52 located in the drive space 5. One end of the wedge 52 is fixedly mounted with a connecting frame 53, and the other end of the connecting frame 53 is fixedly mounted with a clamping member 54.

[0045] One end of the wedge-shaped piece 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.

[0046] A drive cover 55 is fixedly installed on the outer surface of the pressure relief plug 2, and the inclined surface of the wedge 52 faces the outside of the cover 12.

[0047] The outer surface of the cap 12 is provided with toothed grooves, and the clamping member 54 is located at the gap between the outer interface of the cap 12 and the filter bottle 11.

[0048] Specifically, based on Embodiment 1, when the pressure relief plug 2 is turned downwards, it causes the drive cover 55 to move downwards in the drive space 5, thus pressing the inclined surface of the wedge-shaped member 52. This causes the wedge-shaped member 52 to move, and at this time, the elastic column 51 undergoes tensile deformation. As the wedge-shaped member 52 moves toward the pressure relief plug 2, it drives the connecting frame 53 to move, causing the clamping member 54 to move along with it until it contacts the gap at the outer interface of the filter bottle 11 and the cap 12. The clamping member 54 has an L-shaped cross-section that fits the outer interface of the filter bottle 11 and the cap 12. By clamping the filter bottle 11 and the cap 12, it can prevent the high internal pressure of the filter bottle 11 from squeezing the inner circumference of the cap 12, which would cause the cap 12 to expand and break. Preferably, a convex ring can also be fixedly installed on the outer circumference of the filter bottle 11, as shown in the attached instruction manual. Figure 4 As shown at point b, when the clamping member 54 is clamped, its outward protruding part at the bottom is above the convex ring. When the air pressure inside the filter bottle 11 presses the cap 12 upward, the clamping member 54 can be positioned by the interference of the convex ring on the clamping member 54. Since the clamping member 54 is set on the cap 12, the cap 12 is positioned to prevent the cap 12 from detaching from the filter bottle 11, thereby reducing the risk of bottle explosion.

[0049] On the other hand, when unscrewing the cap 12, a wrench is usually used. However, the wrench and the water purifier are separate items, and people often lose the wrench during use, making it difficult to unscrew the cap 12. In this invention, after depressurization, 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 bracket 53 to reset as well. At this time, there is a gap between the connecting bracket 53 and the cap 12, and the number of connecting brackets 53 is greater than one. By holding two connecting brackets 53 and using them as handles, the cap 12 can be unscrewed, improving the practicality of this invention.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
