Description

Technical Field

[0001] This invention relates to the field of water purifier technology, specifically to a locking mechanism and a water purifier. Background Technology

[0002] A water purifier, also called a water purifier machine or water quality purifier, is a water treatment device that performs deep filtration and purification of water according to the requirements for water use.

[0003] Currently, water purifiers are frequently used in daily production and life. They are generally connected in series in the water supply pipeline through connecting pipes to purify water quality. After a period of use, the water purification filter of these water purifiers will generally need to be replaced when its purification capacity deteriorates. If the filter replacement is inconvenient, it will affect the user experience and thus affect their purchase intention.

[0004] Therefore, the purification effect of the filter element is reduced after long-term use, making people feel uneasy during use and unable to meet their needs, thus causing inconvenience to their work. Furthermore, some water purifiers on the market even require professional after-sales personnel to come to the door to replace the filter element, which is not conducive to the widespread promotion of the product.

[0005] In view of this, it is indeed necessary to provide a technical solution to the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a locking mechanism and a water purifier to solve the problem of inconvenient replacement of the water purifier filter element.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0017] A second objective of this invention is to provide a water purifier, comprising a water purifier body, a filter element, and a locking mechanism as described above. The water purifier body includes a first body and a second body, which are fitted together. The first body has a first receiving groove and a second receiving groove. The filter element is disposed in the first receiving groove and includes a fixing block. The locking mechanism is disposed on the second receiving groove and cooperates with the fixing block.

[0024] As an improvement to the water purifier, a water storage cavity is formed between the filter material and the inner wall of the filter cartridge, and the water inlet pipe is connected to the water storage cavity.

[0025] As an improvement to the water purifier, both the first transmission head and the second transmission head are provided with protrusions, and both the first transmission head and the second transmission head are perpendicular to the protrusions.

[0026] As an improvement to the water purifier, both the inlet pipe and the outlet pipe have openings that engage with the protrusion.

Detailed Implementation

[0045] To make the technical solution and advantages of the present invention clearer, the present invention and its beneficial effects will be described in further detail below with reference to specific embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0046] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0048] like Figures 1 to 15 As shown, a locking mechanism includes a base 1, a movable rod 2, a U-shaped rod 3, and a spring 4. One end face of the base 1 has a locking portion 1001 for locking the filter element 10. The movable rod 2 moves linearly on the base 1 and has a mating portion 201 that engages with the locking portion 1001. One end of the U-shaped rod 3 is connected to the base 1, and the other end engages with the movable rod 2. The U-shaped rod 3 is used to position the movable rod 2 when the locking mechanism is in a locked or unlocked state. The spring 4 connects the movable rod 2 and the base 1. The movable rod 2 is slidably connected to the base 1, the mating portion 201 is conical, and a second cover plate 5 is slidably connected to the upper part of the movable rod 2, through which the movable rod 2 passes. This invention locks and unlocks the filter element 10 through a locking mechanism, thereby enabling quick installation and disassembly of the filter element 10. This makes the installation and disassembly of the filter element 10 convenient and quick, effectively solving the problem of inconvenient installation and disassembly of the water purifier filter element 10. It also effectively prevents the filter element 10 from loosening and causing water leakage during use, and provides a strong guarantee for the miniaturization design of water purifiers.

[0049] Spring 4 is a conventional compression spring. During the unlocking process, spring 4 can provide upward force to the movable rod 2.

[0050] More preferably, the side wall of the movable rod 2 is provided with a square groove 7 and a locking groove 6, the locking groove 6 is located on the bottom surface of the square groove 7, and the locking groove 6 is engaged with the U-shaped rod 3.

[0051] More preferably, the locking groove 6 is a closed-loop groove composed of multiple platforms of varying depths and two inclined surfaces.

[0052] Specifically, such as Figure 9As shown, the locking groove 6 divides the bottom of the square groove 7 into three parts. The bottom of the locking groove 6 is designed with six platforms: ①, ②, ③, ④, ⑤, and ⑥. The depth comparison between the bottom plane of the square groove 7 and each platform is: ①>②<③<④<⑤>⑥<①. From these depth relationships, it can be seen that the movement from ① to ② is from a lower to a higher position. Therefore, in order to make it easier and smoother for the U-shaped rod 3 to move from ① to ②, an inclined plane is set between the two platforms ① and ② to connect the two platforms. Similarly, an inclined plane is also set between the two platforms ⑤ and ⑥ to connect them. To change the locking mechanism from the unlocked to the locked state, simply press down on the movable rod 2. The U-shaped rod 3 will move along the trajectory ①→②→③→④. After pressing it to the bottom and releasing, the U-shaped rod 3 will automatically hook onto the lower recess of platform ④, thus locking the mechanism, and spring 4 will be compressed a certain distance. To change the locking mechanism from the locked to the unlocked state, simply press down on the movable rod 2 again to the bottom and release. The movable rod 2 will spring upward under the rebound force of spring 4, and the U-shaped rod 3 will move along the trajectory ④→⑤→⑥→①, finally hooking onto the lower recess of platform ① to unlock the mechanism. Therefore, users only need to lightly press the movable rod 2 to lock or unlock filter 10, making this one-button operation very convenient and quick.

[0053] More preferably, long guide ribs 203 are provided on both opposite sidewalls of the movable rod 2, and short guide ribs 204 are provided on both opposite sidewalls. The radial heights of the two short guide ribs 204 are different. The long guide ribs 203 are located on the left and right sides of the lower outer wall of the movable rod 2, and the short guide ribs 204 are located on the front and rear sides of the lower outer wall of the movable rod 2. The radial heights of the short guide ribs 204 in the front and rear directions are different, which can effectively prevent workers from assembling the movable rod 2 in the wrong direction. Therefore, the movable rod 2 and the base 1 can only cooperate in one direction. After the guide ribs cooperate with the inner wall of the base 1, they can guide the movement of the movable rod 2.

[0054] More preferably, it also includes a retaining ring 8, which is disposed on the base 1 and sleeved on the outside of the U-shaped rod 3. The retaining ring 8 is a cylindrical spring with 2 to 3 coils, produced using wire and processing methods similar to spring 4, and has a certain degree of elasticity. It is used to bind the U-shaped rod 3 to the base 1; because both the retaining ring 8 and the U-shaped rod 3 have a certain degree of elasticity, the bound U-shaped rod 3 has good elasticity, which is very conducive to the sliding of the locking mechanism U-shaped rod 3 within the locking groove 6 of the movable rod 2 of varying depths.

[0055] A water purifier includes a main body, a filter element 10, and a locking mechanism as described above. The main body includes a first body 91 and a second body 92, which are fitted together. The first body 91 has a first receiving groove and a second receiving groove. The filter element 10 is disposed in the first receiving groove and includes a fixing block 101. The locking mechanism is disposed on the second receiving groove and cooperates with the fixing block 101. The locking mechanism is used to limit the filter element 10 by means of the fixing block 101. Specifically, there are three first receiving grooves, and the second receiving groove is located at the axial position of the first body 91. The three first receiving grooves are arranged around the second receiving groove in the circumference, and the spacing between the first receiving grooves is uniform. The locking mechanism blocks the fixing block 101, preventing it from moving upward. Therefore, the filter element 10 cannot move upward, thus achieving the purpose of locking the filter element 10. When it is necessary to unlock the filter element 10, the locking mechanism is controlled to stop blocking the fixing block 101.

[0056] By cooperating with the locking mechanism and the fixing block 101, the filter element 10 can be locked and unlocked with one click, enabling quick replacement of the filter element 10. This makes the filter element 10 easy and quick to install and remove, effectively solving the problem of inconvenient installation and removal of the water purifier filter element 10 and providing a guarantee for the miniaturization design of water purifiers.

[0057] More preferably, the filter element 10 further includes a first cover plate 102, a filter cartridge 103, a filter material 104, a first transmission head 105, and a second transmission head 106. The first cover plate 102 is provided with an outlet pipe and an inlet pipe, which are arranged parallel to each other along the radial direction of the first cover plate 102. The filter cartridge 103 is connected to the first cover plate 102, and a first cavity is formed between the filter cartridge 103 and the first cover plate 102. The filter material 104 is disposed in the first cavity and is connected to the outlet pipe. The first transmission head 105 is connected to the outlet pipe, and a fixing block 101 is connected to the first transmission head 105. The second transmission head 106 is connected to the inlet pipe. Specifically, the fixing block 101 is connected to the middle of the outer wall of the water outlet end of the first transmission head 105. The first cover plate 102 is connected to the filter cartridge 103 by thread or ultrasonic welding. The filter material 104 is a rod-shaped filter material 104. The upper part of the first cover plate 102 is cylindrical. The water outlet pipe and the water inlet pipe are both connected to the cylindrical part of the first cover plate 102. The water outlet pipe and the water inlet pipe are distributed vertically and horizontally. The first cover plate 102 is rotatably provided with a handle, which can be used to pick up the filter element 10. The first transmission head 105 and the second transmission head 106 are both connected at both ends. Both ends of the first transmission head 105 and the second transmission head 106 are provided with sealing ring grooves. After the sealing ring is installed in the sealing ring groove, the first transmission head 105 can be sealed to the inner wall of the water outlet pipe. The second transmission head 106 is sealed to the water inlet pipe. The first transmission head 105 is connected to the water outlet end of the first main body 91, and the second transmission head 106 is connected to the water inlet end of the first main body 91. When water needs to be filtered, water is injected into the water purifier through the second transmission head 106. The water flows through the filter cylinder 103 and the filter media 104 in sequence for filtration. After filtration, the water flows out from the first transmission head 105, thus completing the water purification.

[0058] More preferably, a water storage cavity 107 is formed between the filter media 104 and the inner wall of the filter cartridge 103, and the water inlet pipe is connected to the water storage cavity 107. Specifically, when the water purifier is working, water enters the water storage cavity 107 from the second transmission head 106, and then passes through the filter cartridge 103 and the filter media 104.

[0059] More preferably, both the first transmission head 105 and the second transmission head 106 are provided with protrusions 108, and both the first transmission head 105 and the second transmission head 106 are perpendicular to the protrusions 108. Specifically, the protrusions 108 are axially disposed on the top outer wall of the first transmission head 105 and the second transmission head 106, and the protrusions 108 are elongated.

[0060] More preferably, both the inlet and outlet pipes have openings that engage with the protrusions 108. Specifically, the protrusion 108 on the first transmission head 105 engages with the opening on the outlet pipe, and the protrusion 108 on the second transmission head 106 engages with the opening on the inlet pipe. Both the first transmission head 105 and the second transmission head 106 are vertically downward. By engaging the protrusions 108 with the openings, the first transmission head 105 will not rotate around the axis of the outlet pipe, and the second transmission head 106 will not rotate around the axis of the inlet pipe; they are fixed vertically downward, ensuring the reliability of the installation of the first transmission head 105 and the second transmission head 106, and also facilitating the installation and connection of the filter element 10.

[0061] More specifically, the second cover plate 5 is inverted T-shaped, and a flange face 51 is provided at the lower part of the second cover plate 5. Several semi-circular holes 52 are provided on the flange face 51, and square grooves 53 are provided on the inner walls of the semi-circular holes 52. When assembling the filter element 10, the fixing block 101 on the first transmission head 105 is inserted into the square groove 53. Several fixing holes are also provided on the flange face 51. The fixing holes are connected by screws, which can fix the second cover plate 5 to the top surface of the first body 91. After fixing, a cylindrical internal cavity is formed between the second cover plate 5 and the first body 91. The diameter of this internal cavity is larger than the maximum diameter of the mating part 201 of the movable rod 2, to ensure that the movable rod 2 can slide flexibly up and down in this internal cavity. A boss 54 is provided in the middle of the flange face 51. A central hole is provided in the middle of the top of the boss 54. The upper end of the movable rod 2 passes through the central hole. The lower end of the flange face 51 extends downward to form a reinforcing rib 55. The reinforcing rib 55 can form a sandwich between the flange face 51 and the top surface of the first body 91. The sandwich space is divided into several parts. The number and position of the sandwich space correspond to the number and position of the semi-circular holes 52. Each sandwich space can guide the movement of the corresponding snap-fit ​​part 1001, so that the snap-fit ​​part 1001 can only extend and retract radially under the push of the movable rod 2 mating part 201, and cannot move up and down. A button 202 is provided at the upper end of the movable rod 2. The button 202 is used to seal the space at the top of the movable rod 2.

[0062] The U-shaped rod 3 is made of conventional hard metal wire. During the up and down movement of the movable rod 2, the U-shaped rod 3 cooperates with the locking groove 6 to play a limiting role. The base 1 is T-shaped, and three locking parts 1001 are radially symmetrically arranged on the top of the base 1. Each base 1 position connected to each locking part 1001 is provided with a base 1 screw hole. The base 1 can be fixed to the first body 91 by screws.

[0063] The middle part of the base 1 is sleeve-shaped. The inner wall of the sleeve is provided with matching guide grooves 1002 at the corresponding positions of the long guide rib 203 and the short guide rib 204. A semi-circular mounting groove 1003 is also provided on the inner wall of the sleeve. A positioning post 1004 perpendicular to the bottom surface is also provided at the bottom center of the mounting groove 1003. After the locking mechanism is assembled, the mounting groove 1003 and the movable rod 2 are combined to form a cylindrical mounting groove 1003. The spring 4 is installed in the mounting groove 1003 and sleeved on the positioning post 1004. A cylindrical boss 1005 with a diameter smaller than the outer diameter of the sleeve extends downward from the center of the lower plane of the sleeve. A U-shaped rod 3 groove for installing the U-shaped rod 3 is provided on the side wall of the cylindrical boss 1005. The U-shaped rod 3 groove is connected to the internal space of the sleeve.

[0064] When the filter element 10 needs to be locked, press down on the movable rod 2. The movable rod 2 moves down to compress the spring 4, and the mating part 201 also moves down, thereby slowly pushing the locking part 1001 radially outward a certain distance. When the movable rod 2 is pressed to the bottom, the locking part 1001 is pushed outward to the maximum distance. All the locking parts 1001 on the base 1 are latched above the fixing block 101 of the first transmission head 105, so that the filter element 10 cannot be released upward to achieve the purpose of locking the filter element 10. When unlocking is required, when the movable rod 2 moves upward under the rebound force of the spring 4, the thrust of the mating part 201 on the locking part 1001 will gradually decrease until it disappears completely; the locking part 1001 will slowly retract radially inward under its own rebound force, thereby separating from the fixed block 101, thus achieving the purpose of unlocking the filter element 10. In addition, in order to allow the movable rod 2 to be automatically positioned in the locked state when it is pressed to the lowest point, or to be automatically positioned in the unlocked state when the movable rod 2 is bounced to the highest point by the spring 4, the U-shaped rod 3 is inserted into different grooves on the movable rod 2 in the two states respectively, so as to achieve the purpose of automatic positioning.

[0065] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
