Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a pull-up filter bottle fixing device and its water purifier. Background Technology

[0002] Water purifiers, also known as water purification machines or water quality purifiers, are water treatment devices that deeply filter and purify water according to usage requirements. As people's demands for drinking water hygiene increase, water purifiers are becoming increasingly widely used in various settings (such as homes, businesses, and some entertainment venues). Currently, most water purifier filter bottles are installed using a rotating snap-fit ​​or threaded connection method. This requires multiple rotations of the filter bottle during installation and removal, making the process laborious and cumbersome, and thus has room for improvement. Utility Model Content

[0003] This invention aims to overcome the shortcomings of the prior art by providing a pull-up filter bottle fixing device. Its structure is simple and reasonable. Rotating the handle allows the sealing connector to move along the connecting pipe, enabling it to engage or disengage with the inlet and outlet, facilitating control of the water flow between the water circuit board and the filter bottle. Simultaneously, controlling the engagement or disengagement of the sealing connector with the filter bottle's inlet and outlet via the handle also locks or unlocks the filter bottle, facilitating its installation and removal. Furthermore, since the inlet and outlet are arranged perpendicularly to the filter bottle, the filter bottle is inserted into the cavity and supported by the frame, while the sealing connector is essentially unsupported, ensuring the stability and reliability of the device's operation.

[0004] To achieve the above objectives, this utility model provides a pull-up filter bottle fixing device, including a frame, a water channel plate, a filter bottle, a handle, and a sealing connector; The frame includes a mounting end face and an inlet cavity that extends perpendicularly to the mounting end face and has an inlet structure on the mounting end face. The filter bottle is inserted into the cavity of the frame, and the head of the filter bottle located outside the cavity is provided with several inlet and outlet ports that are arranged perpendicular to the extension axis of the filter bottle. The water circuit board is fixedly installed on the mounting end face of the frame, and the water circuit board is provided with several connecting pipes that correspond one-to-one with the inlet and outlet of the filter bottle. The handle is a U-shaped structure and its two vertical arms are rotatably mounted on both sides of the water channel plate. The sealing connector is disposed between the water circuit plate and the filter bottle and is linked to the handle. The sealing connector has several connecting channels for connecting the corresponding inlet / outlet and the connecting pipe. The sealing connector is movably fitted onto the connecting pipe of the water circuit plate through the connecting channels. When the handle is rotated, it can move the sealing connector along the connecting pipe to achieve the engagement or disengagement of the connecting channel with the inlet / outlet.

[0005] The design further includes: guide grooves arranged opposite each other on the inner walls of the two vertical arms; and a sealing connector located between the two vertical arms of the handle with sliding shafts on both sides that cooperate with the guide grooves.

[0006] The handle is further configured such that at least one vertical arm of the handle is provided with a first protrusion and a second protrusion for abutting against the mounting end face to lock the handle in an unlocked state and a locked state, respectively. The locked state corresponds to the sealing connector engaging with the inlet and outlet, and the unlocked state corresponds to the sealing connector separating from the inlet and outlet.

[0007] The handle is further configured such that it is arranged parallel to the mounting face when locked, and perpendicular to the mounting face when unlocked.

[0008] The configuration is further defined as follows: a cavity is provided on each side of the water channel plate corresponding to the frame, and the two cavities are arranged opposite to each other; and a pipe is provided on both sides of the water channel plate.

[0009] This utility model also provides a water purifier, including a pull-out filter bottle fixing device.

[0010] Compared with the prior art, this utility model has a simple and reasonable structure. By rotating the handle, the sealing connector can be moved along the pipe to engage or disengage with the inlet and outlet, making it convenient to control the flow of water between the water circuit board and the filter bottle. At the same time, controlling the engagement or disengagement of the sealing connector with the inlet and outlet of the filter bottle through the handle can also lock or unlock the filter bottle, thus facilitating the disassembly or assembly of the filter bottle. Furthermore, since the inlet and outlet are arranged perpendicularly to the filter bottle, the filter bottle is inserted into the cavity and is supported by the frame, while the sealing connector is not under pressure, thus ensuring the stability and reliability of the device.

Detailed Implementation

[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0015] This utility model provides a lifting filter bottle 30 fixing device, as follows: Figure 1 and Figure 2 As shown, it includes a frame 10, a water channel plate 20, a filter bottle 30, a handle 40, and a sealing connector 50.

[0016] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the frame 10 includes a mounting end face 11 and an inlet cavity 12 extending perpendicularly to the mounting end face 11. A filter bottle 30 is inserted into the cavity 12 of the frame 10. The filter bottle 30 has several inlet / outlet ports 31 on its head side, located outside the cavity 12, with the outlet direction perpendicular to the extension axis of the filter bottle 30. A water channel plate 20 is fixedly mounted on the mounting end face 11 of the frame 10 and located on the side of the filter bottle 30 with the inlet / outlet ports 31. The corresponding side of the water channel plate 20 has several connecting pipes 21 that correspond one-to-one with the several inlets of the filter bottle 30. The handle 40 has a U-shaped structure, including two vertical arms 41 located on both sides and rotatably engaging with the horizontal sides of the water channel plate 20. Specifically, the horizontal sides of the water channel plate 20 have rotating shafts, and the inner walls of the two vertical arms 41 of the handle 40 are provided with… There is rotation in conjunction with the rotating shaft, thus realizing the rotational connection between the handle 40 and the water circuit plate 20; the sealing connector 50 is movably disposed between the water pipe 21 of the water circuit plate 20 and the inlet / outlet 31 of the filter bottle 30 and is linked to the handle 40. The sealing connector 50 is constructed with several connecting channels 51 for connecting the corresponding inlet / outlet 31 and the water pipe 21. The sealing connector 50 is movably sealed on the water pipe 21 of the water circuit plate 20 through the connecting channels 51. The guiding constraint of the connecting channels 51 and the water pipe 21 can ensure the reliability of the movement of the sealing connector 50; during the rotation of the handle 40, it can link the sealing connector 50 to extend outward along the water pipe 21 so that the connecting channel 51 of the sealing connector 50 is sealed and engaged with the inlet / outlet 31 to realize the connection of the water circuit between the water circuit plate 20 and the filter bottle 30. At this time, it is in the locked state. Figure 2 The filter bottle 30 is stably locked in the insertion cavity 12 of the frame 10; at the same time, the handle 40 can also retract the sealing connector 50 along the pipe 21 during rotation, so that the connecting channel 51 of the sealing connector 50 is separated from the inlet and outlet 31, thereby disconnecting the water passage between the water circuit plate 20 and the filter bottle 30. At this time, it is in the unlocked state. Figure 1 The filter bottle 30 can be easily inserted into or removed from the insertion cavity 12; thus, by rotating the handle 40, the device can be easily switched between the unlocked and locked states, thereby facilitating the disassembly and assembly of the filter bottle 30.

[0017] In this embodiment, as Figure 4 As shown, guide grooves 411 are provided on the inner walls of the two vertical arms 41 of the handle 40. The guide grooves 411 on both sides are arranged opposite to each other. The sealing connector 50 is located between the two vertical arms 41 of the handle 40 and has sliding shafts 52 on both sides that cooperate with the guide grooves 411. In this way, when the handle 40 rotates, it can guide the sliding shafts 52 on the sealing connector 50 to slide through the guide grooves 411 to achieve the effect of linkage of the sealing connector 50.

[0018] In this embodiment, as Figure 4 As shown, at least one vertical arm 41 of the handle 40 is provided with a first protrusion 412 and a second protrusion 413 for abutting against the mounting end face 11 to lock the handle 40 in the unlocked state and the locked state, respectively. Preferably, both vertical arms 41 of the handle 40 are provided with the first protrusion 412 and the second protrusion 413, which can further ensure the stability of the handle 40 in the state. Preferably, the handle 40 is arranged parallel to the mounting end face 11 in the locked state and perpendicular to the mounting end face 11 in the unlocked state. In this way, in the unlocked state, the handle 40 can act as a bracket to facilitate the insertion and removal of the filter bottle 30.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the frame 10 has a cavity 12 on each of the vertical sides corresponding to the water circuit plate 20, and the two cavities 12 are arranged opposite to each other. The two cavities 12 are respectively for inserting the front and rear composite filter bottles 30 and the reverse osmosis filter bottles 30, and the inlet and outlet ports 31 of the two filter bottles 30 are arranged facing each other. Both sides of the water circuit plate 20 are provided with connecting pipes 21 that match the inlet and outlet ports 31 of the filter bottles 30. In some other embodiments, the frame 10 can also be constructed with one or more cavities 12, depending on the number of filter bottles 30 that need to be inserted. At the same time, during use, the filter bottles 30 can be removed from the side or from the top, which can be flexibly selected according to the overall layout.

[0020] This utility model also provides a water purifier with the aforementioned pull-out filter bottle 30 fixing device, which makes it easy to replace the filter bottle 30.

[0021] Compared with the prior art, this utility model has a simple and reasonable structure. By rotating the handle, the sealing connector can be moved along the pipe to engage or disengage with the inlet and outlet, making it convenient to control the flow of water between the water circuit board and the filter bottle. At the same time, controlling the engagement or disengagement of the sealing connector with the inlet and outlet of the filter bottle through the handle can also lock or unlock the filter bottle, thus facilitating the disassembly or assembly of the filter bottle. Furthermore, since the inlet and outlet are arranged perpendicularly to the filter bottle, the filter bottle is inserted into the cavity and is supported by the frame, while the sealing connector is not under pressure, thus ensuring the stability and reliability of the device.

[0022] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
