Description

Technical Field

[0001] The present invention relates to the technical field of water purification devices, and in particular to a filter element and a water purifier. Background Art

[0002] Currently, the filter cartridges used in water purifiers are mostly plug-in filter cartridges. After the filter cartridge is assembled into the casing of the water purifier, it can be carried together with the entire machine. However, before the filter cartridge is assembled, in order to ensure the filtering effect, the filter cartridge has a large diameter. For a normal adult's hand, it takes one or even two hands to hold a filter cartridge. Although there are transportation tools for long-distance delivery, short-distance delivery generally requires manual hand-held transportation, which causes great inconvenience in carrying the filter cartridge and low efficiency.

[0003] At present, water purifiers are generally composed of a shell, a filter element and a water system. In order to reduce the size of the equipment, the filter element is not rotated but directly inserted into the waterway plate. The filter element water nozzle is wrapped with an O-ring. In order to ensure the sealing performance, a lot of force is required when inserting into the integrated waterway plate, and a lot of force is also required when pulling out from the integrated waterway plate. There is no good force structure on the filter bottle body, and currently manual force is mainly used to push and pull out the filter element. At the same time, the filter element is fixed with screws and other means, which increases the complexity and difficulty of operation. Summary of the invention

[0004] In order to solve the technical problem that the existing direct-insertion filter element is inconvenient to carry and transport, the present invention proposes a filter element that can solve the above problem.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions to achieve the above problems:

[0006] A filter core comprises a filter bottle and an inner core arranged in the filter bottle, wherein a handle is hingedly connected to one end of the filter bottle.

[0007] Furthermore, the filter bottle includes a filter bottle head and a bottle body connected to the filter bottle head, a water nozzle is formed on the filter bottle head, and the handle is a ring structure with an open end. The handle is hinged to the filter bottle head through two hinge structures, and the two hinge structures are respectively located on both sides of the water nozzle.

[0008] Furthermore, the two hinged structures are symmetrically arranged on both sides of the water nozzle.

[0009] Furthermore, the hinge structure includes a hinge axis formed on the inner side of the handle and a groove opened on the side wall of the bottle body, the hinge axis is inserted into the groove, and the two ends of the handle extend from the hinge axis along the length direction of the handle to form a connecting arm, and a first claw is formed on the free end of the connecting arm, and the opening direction of the first claw is located in the tangent direction of the arc formed by the rotation of the connecting arm around the hinge axis.

[0010] Furthermore, a reinforcing rib is formed on at least one side of the first claw along its length direction.

[0011] Furthermore, the handle and the connecting arm are connected by an arc transition, and the included angle between the reverse extension lines of the handle and the connecting arm is an acute angle.

[0012] Furthermore, a limiting rib is formed on one side of the groove on the bottle body, the height of the limiting rib is greater than the gap between the handle and the filter bottle, and the limiting rib is used to support the handle to maintain a certain angle.

[0013] Furthermore, a positioning rib is formed on the bottle body at the other side of the groove, and the height of the positioning rib is greater than the gap between the handle and the filter bottle.

[0014] Furthermore, the filter bottle head and the bottle body are an integrally formed structure, an assembly opening is provided at the bottom of the bottle body, and a lower end cover is sealed and fixed at the assembly opening.

[0015] The present invention also proposes a water purifier, including a waterway plate, on which a waterway connecting valve is formed, and also includes a filter element as described in any of the above items, wherein the water nozzle of the filter element is plugged and fixed to the waterway connecting valve.

[0016] Furthermore, a protruding structure is formed on at least one side of the water channel link valve on the water channel plate, and a second claw is formed on the protruding structure. The opening direction of the second claw is opposite to the opening direction of the first claw. When the handle rotates around the axis, the first claw engages or disengages with the second claw.

[0017] Furthermore, there are two protruding structures, and the two protruding structures are respectively located below both sides of the connecting valve.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are: the filter element of the present invention is convenient to carry and transport by hingedly connecting a handle at the end of the filter bottle.

[0019] Other features and advantages of the present invention will become more apparent after reading the detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1

[0031] The filter cartridges currently used in water purifiers are mostly direct-insert quick-connect filter cartridges. The direct-insert filter cartridges have the advantage of easy assembly. However, before the filter cartridges are assembled on the water purifier, they need to be manually carried by hand, which causes great inconvenience in carrying the filter cartridges and has the disadvantage of low efficiency. Based on the above reasons, the present invention proposes a filter cartridge, such as Figure 1As shown, it includes a filter bottle 11 and an inner core (not shown in the figure due to angle reasons) arranged in the filter bottle 11. A handle 12 is hinged at one end of the filter bottle 11. The handle 12 is rotatably connected to the filter bottle 11 through a rotating shaft, wherein the rotating shaft can be fixed on the handle or on the filter bottle 11, as long as the handle 12 can move around the rotating shaft. The filter element of this embodiment is hinged with a handle 12 at the end of the filter bottle 11, and the handle 12 can rotate around the hinge shaft. When the handle is around the top of the filter element, it can be operated and transferred by means of a hand-held handle, which is convenient for handling and carrying. When it is not necessary to transfer, the handle can be around the side of the filter element without affecting the assembly and use of the filter element.

[0032] The direct-insert quick-connect filter element is connected to the waterway plate of the water purifier during assembly. Its connection method is to directly plug it into the waterway plate, which often poses a greater risk of water leakage. In order to improve the sealing between the filter element and the waterway plate, an O-ring or the like is generally provided at the connection port to ensure that the two are tightly connected, while increasing the friction between the two to prevent water leakage and prevent the filter element from falling off the waterway plate. However, this will bring another problem. When replacing the filter element and unplugging the filter element from the waterway plate, a large disengagement force needs to be applied to unplug the filter element. For a traditional filter element, its exterior only includes a filter bottle, a filter bottle head and other structures arranged along the length direction. There is no power-assisting structure or auxiliary structure to assist the user in unplugging the filter element from the waterway plate. The operation is very inconvenient. In this embodiment, the filter bottle 11 includes a filter The bottle head 111 and the bottle body 112 connected to the filter bottle head 111, the filter bottle head 111 is formed with a water spout 113 for connecting to the waterway board, the handle 12 is a ring structure with an open end, the handle 12 is hinged to the filter bottle head 111 through two hinge structures 13, and the two hinge structures 13 are respectively located on both sides of the water spout, that is, the direction of the hinge axis of the hinge structure 13 is not in the same direction as the length direction of the water spout 113. Therefore, the handle can be turned to the side opposite to the water spout 113. When the filter element needs to be pulled out from the waterway board, the bottle body 112 is held with one hand and the handle is held with the other hand and pulled back to apply a disengaging force opposite to the connection direction of the water spout and the waterway board. Therefore, the handle can play a role in assisting the removal of the filter element, solving the problem that it is currently difficult to pull the filter element out of the waterway board.

[0033] Preferably, the hinged structure 13 and the faucet are located on the same horizontal plane. This ensures that when the handle is pulled back, the direction of the applied force is parallel to the length direction of the faucet or on the same straight line. Therefore, the effective power can be increased, and the force applied is minimized while the filter element can be pulled out.

[0034] In order to ensure that both sides of the handle are evenly stressed when the filter element is removed, the two hinge structures 13 are preferably symmetrically arranged on both sides of the water nozzle 113 to minimize damage to the single-sided hinge structure.

[0035] The filter element and the waterway plate are usually assembled in the water purifier before leaving the factory. The filter element and the waterway plate are prone to fall off during transportation, or the filter element and the waterway plate may fall off due to the impact and shaking of the water flow during operation. The falling of the filter element will cause the filter element to be contaminated and bring negative impact on product quality. In order to fix the filter element in the water purifier and prevent the filter element 12 from falling off in the water purifier, Figure 2-Figure 4 As shown, the hinge structure 13 includes a hinge axis 131 formed on the inner side of the handle 12 and a groove 132 opened on the side wall of the bottle body. The hinge axis 131 is inserted into the groove 132. The two ends of the handle 12 extend from the hinge axis 131 along the length direction of the handle 12 to form a connecting arm 14. A first claw 15 is formed on the free end of the connecting arm 14. The opening direction of the first claw 15 is located in the tangent direction of the arc formed by the rotation of the connecting arm 14 around the hinge axis 131. The waterway plate should have a clamping structure that cooperates with the first clamping claw 15. After the filter element 12 is inserted into the waterway plate, the handle 12 is rotated around the hinge shaft 131 to screw the first clamping claw 15 into the clamping structure that cooperates with it on the waterway plate, thereby achieving a fixed connection with the waterway plate, and then fixing the filter element to the waterway plate. This can prevent the water nozzle of the filter element 12 from falling off from the waterway plate during transportation or use. The solution of this structure is simple to implement. By arranging a handle on the filter element, it can achieve multiple uses and can simultaneously solve multiple technical problems existing in the current filter element.

[0036] The opening of the first clamping claw 15 can be downward or upward, as long as the clamping structure on the waterway plate meets the requirements of matching, that is, when the opening of the first clamping claw 15 is downward, the clamping structure on the waterway plate is upward, and when the opening of the first clamping claw 15 is upward, the clamping structure on the waterway plate is downward, and the first clamping claw 15 is engaged with the clamping structure on the waterway plate by rotating the handle. In this embodiment, the first clamping claw 15 is opened downward as an example.

[0037] Among them, the positions of the hinge axis and the groove of the hinge structure 13 are not limited to the above examples. The hinge axis can also be formed on the side wall of the bottle body, and the groove can be opened on the inner side of the handle, which can also play the role of hinged connection between the handle 12 and the bottle body. Alternatively, grooves can be opened on both the handle and the bottle body, and the two ends of the hinge axis can be respectively inserted into the grooves of the handle and the bottle body to realize the hinged connection between the two. All schemes that can realize the hinged connection between the handle and the bottle body belong to the protection scope of the present invention.

[0038] In order to improve the supporting and fixing strength of the first claw 15, as Figure 4As shown, it is preferred that the first claw 15 is formed with a reinforcing rib 151 along at least one side of its length direction. In this embodiment, reinforcing ribs 151 are formed on both sides of the first claw 15, so as to further strengthen the strength of the first claw 15. The number of reinforcing ribs 151 is not limited to the example in this embodiment, and can be arranged according to the actual space. The position of the reinforcing rib 151 is also not limited to the example in this embodiment, and can also be set on the non-engaging surface of the first claw 15 or other positions, which can increase the strength of the first claw 15. The protruding rib-like structures formed on the surface of the first claw 15 belong to the protection scope of the present invention.

[0039] like Figure 4 , Figure 5 As shown, in order to improve the center of the handle 12 and facilitate the operation of rotating the handle to clamp the first claw 15 on the waterway plate or to separate the first claw 15 from the waterway plate, the angle between the handle 12 and the reverse extension line of the connecting arm 14 is The handle 12 is an acute angle, and by making the center of gravity of the handle 12 relatively higher than the center of gravity of the connecting arm 14, the handle 12 is more in line with the principle of human mechanics when rotating, and the handle can be rotated conveniently. Moreover, after the first claw 15 is clamped with the waterway plate, the handle 12 still remains in an upward tilted state, which can save the space of the filter bottle under the handle 12, that is, reduce the shielding of the filter bottle by the handle 12. In order to prevent the sharp corners at the connection between the handle and the connecting arm from scratching the user, it is preferred that the handle 12 and the connecting arm 14 are connected by an arc transition.

[0040] After the first claw 15 is engaged with the waterway plate, since the handle 12 remains tilted upward, in order to prevent the handle 12 from moving downward due to its own gravity or being accidentally hit by an external force, causing the first claw 15 to be disengaged from the engaging structure on the waterway plate, such as Figure 1 , Figure 2 As shown, a limiting rib 16 is formed on one side of the groove on the bottle body 112, and the height of the limiting rib 16 is greater than the gap between the handle 12 and the filter bottle 11. When the handle is rotated upward around the axis so that the first claw 15 is engaged with the waterway plate, the limiting rib 16 is located below the handle 12 to support the handle 12. The limiting rib 16 is used to support the handle at a certain angle.

[0041] Similarly, if Figure 1 , Figure 2 As shown, in order to prevent the handle 12 from over-rotating, a positioning rib 17 is formed on the bottle body 112 on the other side of the groove, and the height of the positioning rib 17 is greater than the gap between the handle 12 and the filter bottle 11.

[0042] Since the handle 12 needs to be hinged with the filter bottle head 111, it is preferred that the filter bottle head 111 and the bottle body 112 are integrally formed, which will save the process of assembling the filter bottle head 111 and the screen body 112. The bottom of the bottle body 112 is provided with an assembly port, and the inner core is inserted into the filter bottle through the assembly port and fixed. Figure 1 As shown, a lower end cap 114 is sealed and fixed at the assembly opening, which is used to seal the inner core in the cavity of the filter bottle and also can play a role in supporting the inner core.

[0043] The lower end cap 114 and the bottle body 112 are preferably fixed by rotary melting, which has high fixing efficiency and good sealing performance. At the same time, since the lower end cap 114 is located below the bottle body 112, at the end away from the water outlet of the inner core, the influence of rotary melting on the sealing performance between the inner core and the filter bottle can be avoided.

[0044] Embodiment 2

[0045] This embodiment provides a water purifier, such as Figure 6-Figure 8 It can be seen that the waterway plate 20 is formed with a waterway connecting valve 21, and the filter element described in the first embodiment is also included. Figure 1-5 As recorded, the water nozzle 113 of the filter element is plugged and fixed to the water channel connecting valve 21 .

[0046] like Figure 7 , Figure 8 As shown, a protruding structure 22 is formed on at least one side of the waterway link valve 21 on the waterway plate 20, and a second claw 23 is formed on the protruding structure 22. The opening direction of the second claw 23 is opposite to the opening direction of the first claw 15, that is, the opening of the first claw 15 in the first embodiment faces downward, and the opening of the second claw 23 in this embodiment faces upward. When the handle 12 rotates around the axis, the first claw 15 and the second claw 23 are engaged or disengaged.

[0047] In order to improve the fixing strength between the handle and the waterway plate, there are two protruding structures 22 , and the two protruding structures 22 are respectively located below the two sides of the waterway connecting valve 21 .

[0048] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
