For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Based on the problem mentioned in the background technology that the bottle body of the existing pre-filter is large and heavy after adding water, there is a risk of the filter bottle falling when replacing the filter element, resulting in a poor user experience, the utility model provides a filtering device.

[0037] Specifically, Figures 1 to 6 As shown, the installation structure of the utility model includes a filter bottle 1, a valve head 2, and a locking member 3 and a locking member arranged between the filter bottle 1 and the valve head 2. The locking member 3 is arranged to lock the filter bottle 1 on the valve head 2 when it is in a locked state, and the locking member 3 is also arranged to allow the filter bottle 1 to be detached from the valve head 2 when it is in an unlocked working state.

[0041] Preferably, if Figures 1 to 6 As shown, the locking component of the utility model includes a first locking structure 41 arranged on the filter bottle 1 and a second locking structure 42 arranged on the valve head 2. When installed, the first locking structure 41 abuts against the second locking structure 42 to prevent the filter bottle 1 from falling off the valve head 2.

[0042] Through such a configuration, compared with configuring the locking component to include a first clamping structure arranged on the filter bottle 1 and a second clamping structure arranged on the valve head 2, configuring the locking component to include a first locking structure 41 arranged on the filter bottle 1 and a second locking structure 42 arranged on the valve head 2 can make the matching structure between the filter bottle 1 and the valve head 2 simpler, reduce the processing difficulty of the filter bottle 1 and the valve head 2, and enhance the user experience.

[0043] Specifically, Figure 5 and Figure 6 As shown, the first locking structure 41 includes a connected first connecting portion 411 and a first abutting portion 412, and the first connecting portion 411 is arranged on the filter bottle 1. The second locking structure 42 includes a connected second connecting portion 421 and a second abutting portion 422, and the second connecting portion 421 is arranged on the valve head 2. When the locking member 3 is in an unlocked state, the first abutting portion 412 can abut against the second abutting portion 422 to prevent the filter bottle 1 from falling off the valve head 2.

[0044] It should be noted that, in actual applications, those skilled in the art may arrange the first abutment portion 412 to be perpendicular to the first connection portion 411, or may arrange the first abutment portion 412 to be at an acute angle to the first connection portion 411, and so on. Such adjustments and changes to the specific settings of the first connection portion 411 and the first abutment portion 412 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0045] Preferably, if Figure 5 and Figure 6As shown, the first abutting portion 412 is vertically arranged with respect to the first connecting portion 411 .

[0046] It should be noted that, in actual applications, those skilled in the art may configure the first abutment portion 412 and the first connecting portion 411 to be integrally formed, or, may configure the first abutment portion 412 and the first connecting portion 411 to be fixedly connected by fasteners, or, may configure the first abutment portion 412 and the first connecting portion 411 to be connected by welding or ultrasonic welding, etc. Such adjustments and changes to the specific connection method of the first abutment portion 412 and the first connecting portion 411 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0047] Preferably, the first abutting portion 412 and the first connecting portion 411 are integrally formed.

[0048] It should also be noted that, in actual applications, those skilled in the art may arrange the second abutment portion 422 to be perpendicular to the second connection portion 421, or may arrange the second abutment portion 422 to be at an acute angle to the second connection portion 421, and so on. Such adjustments and changes to the specific settings of the second connection portion 421 and the second abutment portion 422 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0049] Preferably, if Figure 5 and Figure 6 As shown, the second abutting portion 422 is vertically arranged with respect to the second connecting portion 421 .

[0050] It should be noted that, in actual applications, those skilled in the art may configure the second abutment portion 422 and the second connecting portion 421 to be integrally formed, or, may configure the second abutment portion 422 and the second connecting portion 421 to be fixedly connected by fasteners, or, may configure the second abutment portion 422 and the second connecting portion 421 to be connected by welding or ultrasonic welding, etc. Such adjustments and changes to the specific connection method of the second abutment portion 422 and the second connecting portion 421 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0051] Preferably, the second abutting portion 422 and the second connecting portion 421 are integrally formed.

[0052] It should be noted that the present invention does not impose any limitation on the specific matching mode between the first abutment portion 412 and the second abutment portion 422 , as long as the first abutment portion 412 can abut against the second abutment portion 422 to prevent the filter bottle 1 from moving toward the valve head 2 .

[0053] In a specific embodiment, the first abutting portion 412 and / or the second abutting portion 422 are elastic so that the first abutting portion 412 passes over the second abutting portion 422 and moves above the second abutting portion 422 , thereby facilitating the first abutting portion 412 to abut against the second abutting portion 422 .

[0054] In another specific embodiment, the filter bottle 1 can be rotated relative to the valve head 2 along a first direction so that the first abutting portion 412 is aligned with the second abutting portion 422 .

[0055] Preferably, if Figure 6 As shown, the filter bottle 1 rotates along the first direction relative to the valve head 2 so that the first abutment portion 412 is aligned with the second abutment portion 422. A limiting structure 423 is also provided on the filter bottle 1 and / or the valve head 2. The limiting structure 423 is configured to limit the filter bottle 1 from continuing to rotate along the first direction relative to the valve head 2 when the first abutment portion 412 is aligned with the second abutment portion 422.

[0056] Through such an arrangement, compared with the form in which the first abutting portion 412 and / or the second abutting portion 422 are arranged to be elastic so that the first abutting portion 412 abuts against the second abutting portion 422, the first abutting portion 412 is arranged to be aligned with and abut against the second abutting portion 422 when the filter bottle 1 rotates relative to the valve head 2. This can improve the abutment stability between the first abutting portion 412 and the second abutting portion 422, so that the filter bottle 1 can be more stably suspended under the valve head 2 when the filter bottle 1 is replaced, and the filter bottle 1 can be more effectively prevented from falling, thereby further improving the user experience.

[0057] It should be noted that, in actual applications, technical personnel in this field may set the first direction to be clockwise, or may also set the first direction to be counterclockwise, and so on. Such adjustment and change of the specific rotation direction of the first direction does not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0058] Exemplarily, the first direction is clockwise.

[0059] It should be noted that, in actual applications, those skilled in the art may only set the limiting structure 423 on the filter bottle 1, or may set the limiting structure 423 on the valve head 2, or may set the limiting structure 423 on both the filter bottle 1 and the valve head 2, and so on. Such adjustments and changes to the specific setting position of the limiting structure 423 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0060] Preferably, if Figure 6 As shown, the limiting structure 423 is arranged on the valve head 2 .

[0061] It should be noted that, in actual applications, those skilled in the art may set the limiting structure 423 to a limiting plate, or may set the limiting structure 423 to a limiting rib, or may set the limiting structure 423 to any other possible form, etc. Such adjustments and changes to the specific structural form of the limiting structure 423 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0062] Preferably, if Figure 6 As shown, the limiting structure 423 is a limiting plate provided on the second connecting portion 421 , and when the first abutting portion 412 is aligned with the second abutting portion 422 , the first connecting portion 411 abuts against the limiting plate.

[0063] Through such an arrangement, when the first abutment portion 412 is aligned with the second abutment portion 422, the first connecting portion 411 and / or the first abutment portion 412 can be abutted against the limit plate, thereby limiting the rotation of the first connecting portion 411 and / or the first abutment portion 412 relative to the valve head 2, thereby preventing the first abutment portion 412 and the second abutment portion 422 from separating from each other, thereby ensuring that the first abutment portion 412 can stably abut against the second abutment portion 422 when replacing the filter bottle 1, further improving the user experience.

[0064] It should be noted that, in actual applications, those skilled in the art may set the number of the first locking structures 41 to one, and accordingly, the number of the second locking structures 42 is also one, or the number of the first locking structures 41 may be set to two, and accordingly, the number of the second locking structures 42 is also two and is arranged one-to-one with the first locking structures 41, or the number of the first locking structures 41 may be set to multiple, and accordingly, the number of the second locking structures 42 is also multiple and is arranged one-to-one with the first locking structures 41, and so on. Such adjustments and changes to the specific setting quantities of the first locking structures 41 and the second locking structures 42 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0065] Preferably, if Figure 5 and Figure 6 As shown, there are two first locking structures 41 and the two first locking structures 41 are spaced apart along the circumference of the filter bottle 1 , and there are also two second locking structures 42 and they are arranged in one-to-one correspondence with the first locking structures 41 .

[0066] By providing two first locking structures 41 and second locking structures 42, when the filter bottle 1 is replaced, when the locking member 3 is in the unlocked state, the filter bottle 1 can be more stably suspended under the valve head 2, thereby reducing the risk of the filter bottle 1 tilting or falling due to uneven force, thereby further improving the user experience.

[0067] It should be noted that, in actual applications, those skilled in the art may arrange the locking member 3 between the valve head 2 and the filter bottle 1, or, may arrange the filtration device to also include a cover body 21, with the locking member 3 arranged between the cover body 21 and the filter bottle 1, and so on. Such adjustments and changes to the specific arrangement of the locking member 3 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0068] Preferably, if Figure 1 and Figure 2 As shown, a cover body 21 is provided on the valve head 2, and the locking member 3 includes a first locking structure 31 provided on the filter bottle 1 and a second locking structure 32 provided on the cover body 21. When installed, the first locking structure 31 and the second locking structure 32 cooperate to lock the filter bottle 1 on the valve head 2.

[0069] Through such a configuration, compared with the form of configuring the locking member between the valve head 2 and the filter bottle 1, configuring the locking member 3 between the cover body 21 and the filter bottle 1 can improve the installation stability between the filter bottle 1 and the valve head 2, better prevent the filter bottle 1 from falling off the valve head 2, and further enhance the user experience.

[0070] It should be noted that, in practical applications, the present invention does not impose any limitation on the specific arrangement of the locking member 3 , as long as the filter bottle 1 can be locked on the valve head 2 .

[0072] In another specific embodiment, Figure 1 and Figure 2 As shown, the first locking structure 31 is a locking pin, and the second locking structure 32 is a locking groove. When the cover body 21 rotates relative to the valve head 2, the locking pin can slide along the locking groove so that the locking pin is locked in the locking groove.

[0073] Although both of the above two embodiments can fix the filter bottle 1 on the valve head 2, compared with the first locking structure 31 and the second locking structure 32 being in the form of a locking bolt and a locking hole, setting the first locking structure 31 as a locking pin and setting the second locking structure 32 as a locking groove can improve the installation efficiency between the filter bottle 1 and the valve head 2, and further enhance the user experience.

[0074] Preferably, if Figure 1 and Figure 2 As shown, the first locking structure 31 is a locking pin, and the second locking structure 32 is a locking groove. When the cover body 21 rotates relative to the valve head 2, the locking pin can slide along the locking groove so that the locking pin is fixed in the locking groove.

[0075] Specifically, the locking groove is an arc-shaped groove.

[0076] It should be noted that, in actual applications, those skilled in the art may set the number of the first locking structures 31 to one, and accordingly, the number of the second locking structures 32 is also one, or the number of the first locking structures 31 may be set to two, and accordingly, the number of the second locking structures 32 is also two, and so on. Such adjustments and changes to the specific setting quantity of the locking structure do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0077] Preferably, if Figure 1 , Figure 2 , Figures 3 to 6 As shown, there are two first locking structures 31 and the two first locking structures 31 are spaced apart along the circumference of the filter bottle 1 , and there are also two second locking structures 32 and they are arranged one-to-one correspondingly to the first locking structures 31 .

[0078] By setting the number of the first locking structure 31 and the second locking structure 32 to two, the filter bottle 1 can be more stably installed on the valve head 2, avoiding the problem of water leakage caused by loose installation of the filter bottle 1, and further improving the user experience.

[0079] Preferably, if Figure 1 and Figure 2 As shown, a gripping portion 22 is provided on the cover body 21 , so that the user can rotate the cover body 21 relative to the valve head 2 by means of the gripping portion 22 .

[0080] By providing the gripping portion 22, it is possible to facilitate the user to rotate the cover body 21 relative to the valve head 2 with the help of the gripping portion 22, thereby further improving the installation efficiency between the filter bottle 1 and the valve head 2 and further enhancing the user experience.

[0081] It should be noted that, in actual applications, those skilled in the art may set the holding portion 22 as a handle, or may set the holding portion 22 as a handle, or may set the holding portion 22 to any other possible form, as long as it is convenient for the user to use the holding portion 22 to rotate the cover body 21 relative to the valve head 2, etc. Such adjustments and changes to the specific setting type of the holding portion 22 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0082] Preferably, the grip portion 22 is a push-down handle.

[0083] When installing the filter bottle 1 on the valve head 2, first stagger the first locking structure 41 and the second locking structure 42, and make the first abutment portion 412 higher than the second abutment portion 422, then rotate the filter bottle 1 relative to the valve head 2 so that the first abutment portion 412 is aligned with the second abutment portion 422, press the holding portion 22 downward to rotate the cover body 21 relative to the valve head 2, so that the locking pin slides along the locking groove and is locked in the locking groove, at this time the locking member is in a locked state, and the installation of the filter bottle 1 on the valve head 2 is achieved; when the filter bottle 1 needs to be removed from the valve head 2, hold the holding portion 22 to rotate the cover plate 21 in the opposite direction relative to the valve head 2, so that the locking pin is disengaged from the locking groove, at this time the locking member is in an unlocked state, and the first abutment portion 412 can abut against the second abutment portion 422 to prevent the filter bottle 1 from falling off the valve head 2, thereby avoiding splashing caused by the filter bottle 1 falling.

[0084] In addition, the utility model also provides a water purification device, which includes any one of the filtering devices introduced above.
