Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a water dispenser that facilitates filter replacement. Background Technology

[0002] In pursuit of better water quality, many water dispensers are equipped with filtration functions and have relatively simple filter cartridge removal and replacement structures. However, for some water dispenser products with relatively fixed installations, such as overhead showers, their installation positions are generally high, making it inconvenient for users to remove and replace the filter cartridges. As a result, many overhead showers do not have filtration functions. Therefore, this utility model provides a structure that facilitates filter cartridge replacement. At the same time, this structure also has a function to prevent accidental activation, which can avoid the situation where parts fall and are damaged due to accidental unlocking. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a water outlet structure that facilitates filter replacement.

[0004] A water outlet device for easy filter replacement includes a water outlet body, a water outlet cover, and a quick-release assembly.

[0005] The main body of the water outlet is provided with an installation cavity that connects to the water inlet channel, and the installation cavity is provided with an opening for inserting the filter element.

[0006] The quick-release assembly is installed at the opening of the installation cavity and includes a locking member, an unlocking member, and an auxiliary protrusion. The locking member is installed near the periphery of the opening to restrict and maintain the state of the water outlet cover blocking the opening. The unlocking member is rotatably installed inside the water outlet body and is linked to the locking member. The unlocking member has a toggle switch extending to the outer periphery of the water outlet body. The auxiliary protrusion is located on the outer periphery of the water outlet body and is opposite to the toggle switch. In use, by squeezing the toggle switch and the auxiliary protrusion, the toggle switch is driven to move towards the auxiliary protrusion, which drives the unlocking member to rotate. The unlocking member rotates and drives the locking member to switch to the unlocked state, and the water outlet cover and the opening are released from their relatively fixed state, so that the user can replace the filter element in the installation cavity. Afterwards, the user only needs to seal the installation cavity again with the water outlet cover, and the locking member will lock the water outlet cover again.

[0007] This invention, by setting a quick-release component, enables the outlet cover to be quickly unlocked, thereby facilitating the removal of the outlet cover. This is beneficial for the replacement and installation of filter cartridges in water dispensers that are installed high or difficult to disassemble. In addition, the quick-release component adopts an unlocking structure that involves pinching the toggle switch and the auxiliary protrusion, which can prevent accidental activation.

[0008] Preferably, the periphery of the water outlet cover is provided with a limiting groove, and the locking member forms a locking tongue facing the axis of the mounting cavity. The locking member is engaged with the limiting groove through the locking tongue to restrict the state of the water outlet cover blocking the opening.

[0009] Preferably, the limiting groove is an annular groove, which can cooperate with the locking member at various angles, improving the convenience of assembly.

[0010] Preferably, the end of the water outlet cover facing the installation cavity is provided with a connector, and the limiting groove is provided on the periphery of the connector. When the water outlet cover blocks the opening, the connector is inserted into the opening, and the periphery of the opening is provided with a guide port. The locking tongue enters the installation cavity through the guide port and is locked into the limiting groove.

[0011] Preferably, the locking member is movably installed along the radial direction of the mounting cavity, and a first spring is provided between the locking member and the water outlet body. The first spring pushes the locking member toward the center of the mounting cavity. The unlocking member drives the locking member away and further compresses the first spring. At this time, the first spring provides the locking member with the power to reset.

[0012] Preferably, the locking member has a push rod perpendicular to the direction of movement, and the unlocking member has an unlocking part between the push rod and the mounting cavity. During the unlocking process, the unlocking part moves and pushes the push rod away from the mounting cavity, thereby driving the locking member to switch to the unlocked state. The unlocking structure is simple and easy to form.

[0013] Preferably, to reduce the structural complexity of the unlocking component, the unlocking part is a groove for accommodating the push rod, and one side wall of the groove is the unlocking surface. The unlocking surface is an inclined surface or an arc surface, and during the unlocking process, it gradually enters between the push rod and the mounting cavity, and pushes the push rod to move.

[0014] Preferably, there are three locking members, evenly distributed on the outer periphery of the mounting cavity. The unlocking member is annular and sleeved on the outer periphery of the mounting cavity. There are also three unlocking parts, with each of the three locking members distributed on the unlocking part. A second spring is provided between the unlocking part and the water outlet body. The second spring pushes the toggle switch away from the auxiliary protrusion, keeping the unlocking part in a state where the push rod is released, thereby preventing the unlocking part from keeping the locking member in an unlocked state.

[0015] Preferably, to enable quick disassembly of the water outlet cover, a push-out assembly is provided between the water outlet body and the water outlet cover. The push-out assembly includes a push-out member and a third spring. One end of the push-out member is telescopically installed in a guide hole of the water outlet body, and the other end passes through the guide hole and is provided with a buckle. The other end of the push-out member is provided with a push-out head. The third spring is compressed between the push-out member and the water outlet body and pushes the push-out head to hold the water outlet cover in place. When the locking member is in the unlocked state, the push-out assembly will automatically push the water outlet cover out.

[0016] Preferably, to enhance the functionality of the water outlet, a water outlet state switching function is also provided. The water outlet cover has a connected water passage, an installation cavity, and at least two water outlet channels. A rotary switching valve core is provided in the installation cavity. The water outlet panel of the water outlet cover has a toggle switch, which is rotatably installed in the water outlet cover and drives the rotary switching valve core to switch any water outlet channel and water passage to be connected. The water outlet channels form different water outlets at the water outlet end of the water outlet panel.

[0017] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0018] This utility model, by setting a quick-release component, enables the cap to be quickly unlocked, thereby facilitating the removal of the cap. This is beneficial for the replacement and installation of filter cartridges in water outlets that are installed high or difficult to disassemble. In addition, the quick-release component adopts an unlocking structure that involves pinching the toggle switch and the auxiliary protrusion, which can prevent accidental activation and also allows for one-handed operation. This allows one hand to unlock while the other hand holds the filter to prevent it from falling out suddenly.

[0019] It adopts a push rod and a groove-shaped unlocking part, which has the advantages of simple structure, easy molding, easy assembly and easy unlocking;

[0020] The unlocking component is installed by rotating it around the outer periphery of the mounting cavity, and the installation structure is simple, firm and reliable.

[0021] An ejection assembly is also provided between the water outlet body and the water outlet cover, which can enable quick disassembly of the water outlet cover. Attached Figure Description

[0036] The water outlet body 1 is provided with an installation cavity 12 that connects to the water inlet channel 11, and the installation cavity 12 is provided with an opening 121 for the filter element 4 to be installed.

[0037] The quick-release assembly 3 is installed at the opening 121 of the mounting cavity 12 and includes a locking member 31, an unlocking member 32, and an auxiliary protrusion 33. The locking member 31 is installed near the periphery of the opening 121 to restrict and maintain the state of the water outlet cover 2 blocking the opening 121. The unlocking member 32 is rotatably installed inside the water outlet body 1 and is linked to the locking member 31. The unlocking member 32 is provided with a toggle switch 321 extending to the outer periphery of the water outlet body 1. The auxiliary protrusion 33 is located on the outer periphery of the water outlet body 1 and is connected to the toggle switch 32. In use, by squeezing the toggle switch 321 and the auxiliary protrusion 33, the toggle switch 321 is driven to move toward the auxiliary protrusion 33, which in turn drives the unlocking member 32 to rotate. The unlocking member 32 rotates and drives the locking member 31 to switch to the unlocked state, thus releasing the relative fixed state between the water outlet cover 2 and the opening 121. This allows the user to replace the filter element 4 in the mounting cavity 12. Afterward, the user only needs to seal the mounting cavity 12 with the water outlet cover 2 again, and the locking member 31 will lock the water outlet cover 2 again.

[0038] In one embodiment, the locking structure of the locking member 31 includes a limiting groove 211 on the periphery of the water outlet cover 2, and a locking tongue 311 formed on the part of the locking member 31 facing the axis of the mounting cavity 12. The locking member 31 engages with the limiting groove 211 through the locking tongue 311 to restrict the state of the water outlet cover 2 from blocking the opening 121. Preferably, the limiting groove 211 is an annular groove, which allows it to engage with the locking member 31 at various angles, improving the ease of assembly.

[0039] Furthermore, in another embodiment, the end of the water outlet cover 2 facing the mounting cavity 12 is provided with a connector 21, and the limiting groove 211 is provided on the periphery of the connector 21. When the water outlet cover 2 blocks the opening 121, the connector 21 is inserted into the opening 121, and the periphery of the opening 121 is provided with a guide port 1211. The locking tongue 311 enters the mounting cavity 12 through the guide port 1211 and is locked into the limiting groove 211.

[0040] Based on the above embodiments, regarding the specific structure of the locking member 31, in one embodiment, the locking member 31 is radially movably installed along the mounting cavity 12, and a first spring 34 is provided between the locking member 31 and the water outlet body 1. The first spring 34 pushes the locking member 31 toward the center of the mounting cavity 12. The unlocking member 32 drives the locking member 31 away and further compresses the first spring 34. At this time, the first spring 34 provides the power for the locking member 31 to reset. In addition, the locking member 31 is provided with a push rod 312 perpendicular to the direction of movement. The unlocking member 32 has an unlocking part 322 between the push rod 312 and the mounting cavity 12. During the unlocking process, the unlocking part 322 moves and pushes the push rod 312 away from the mounting cavity 12, and drives the locking member 31 to switch to the unlocked state. The unlocking structure is simple and easy to form.

[0041] Furthermore, in another embodiment, to reduce the structural complexity of the unlocking member 32, the unlocking part 322 is a groove for accommodating the push rod 312, and one side wall of the groove is the unlocking surface 3221. The unlocking surface 3221 is an inclined surface or an arc surface, and during the unlocking process, it gradually enters between the push rod 312 and the mounting cavity 12, and pushes the push rod 312 to move.

[0042] Based on the above embodiment, there are three locking members 31, which are evenly distributed on the outer periphery of the mounting cavity 12.
