Description

Technical Field

[0001] The utility model relates to the technical field of medical filtering devices, in particular to an oral pure water antibacterial filter. Background Art

[0002] The existing Chinese utility model patent with announcement number CN218392430U discloses a filtering device for producing oral antibacterial liquid. The rotating plate is rotated so that the rotating plate and the notch of the through groove are in the same direction. At this time, the rotating plate has no resistance pressure, and each rotating plate is pressed into the inside of the placement groove. At the same time, the annular plate 2 is slightly rotated so that the annular plate 2 presses against the rotating plate and no longer bounces up. Then the rotation is continued to move the connecting rod from the rod groove to the ball groove. At this time, the ball has no resistance pressure restriction, and the annular plate 2 can be removed. At this time, the filter element is removed and replaced, which facilitates the disassembly and cleaning of the filter element and improves people's work efficiency.

[0003] The aforementioned patent still has the following drawbacks: during installation, the ball grooves at the bottom of the second annular plate must be aligned one-to-one with the balls, and then the second annular plate must be rotated and the two rotating plates must be adjusted to coincide with the through-grooves. During disassembly, the two rotating plates must also be adjusted first, while the ball grooves at the bottom of the second annular plate are simultaneously rotated to align with the balls. The disassembly and assembly process requires aligning multiple ball grooves with the balls one-to-one, and the two rotating plates must be adjusted in a distributed manner. This makes the entire disassembly and assembly process complex, and the ease of assembly and disassembly still needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 - Figure 7, this embodiment provides an oral pure water antibacterial filter, including a filter box 1, a box cover 2 installed on the filter box 1, an annular plate 3 is fixed in the filter box 1, an annular plate 2 4 is provided at the top of the annular plate 3, and a filter element 5 is installed at the bottom of the annular plate 2 4, the annular plate 3 includes an annular support plate 31 and an annular docking plate 32 fixed to the top of the annular support plate 31; and the annular plate 2 4 includes an annular support plate 2 41 and an annular docking plate 2 42 fixed to the bottom of the annular support plate 2 41; a plurality of slide grooves 61 are provided on the inner wall of the annular docking plate 2 42, and a card column 62 is slidably connected in each slide groove 61; a plurality of card grooves 63 are provided on the outer wall of the annular docking plate 32, and the card column 62 corresponds to the card groove 63 one by one; an adjusting member 7 for controlling the card column 62 to be synchronously engaged in the card groove 63 is provided on the annular plate 2 4.

[0028] Specifically, the adjusting member 7 includes a mother rope 71, a child rope 72, a compression spring 73, an arc-shaped connecting column 74, and an operating rod 75; an annular rope groove 81 is provided on the top of the annular docking plate 42, and an arc-shaped adjusting groove 82 is provided on the top of the annular support plate 41, and the arc-shaped adjusting groove 82 is connected to the annular rope groove 81; and the mother rope 71 is arranged in the annular rope groove 81; one end of the compression spring 73 is fixedly connected to the clamping column 62, and the other end is fixedly connected to the slide groove 61; one end of the child rope 72 is fixedly connected to the clamping column 62, and the other end is fixedly connected to the mother rope 71; the arc-shaped connecting column 74 is slidably arranged in the annular rope groove 81, and is fixed to the arc-shaped connecting column 74 at the bottom end of the operating rod 75, and the end of the operating rod 75 that is arc-shaped away from the connecting column extends out of the arc-shaped adjusting groove 82.

[0029] The following is a further description of specific usage scenarios. After the filter element 5 is installed, the clamping column 62 is clamped into the clamping groove 63 under the elastic force of the compression spring 73. The annular plate 2 4 is fixed to the annular plate 1 3, and the filter element 5 is fixed to the bottom of the annular plate 2 4. When the filter element 5 needs to be replaced, the box cover 2 is first opened, and then the operating rod 75 is pushed to move the operating rod 75 along the arc-shaped adjustment groove 82. When the operating rod 75 moves, it pulls the main rope 71, which in turn drives all the child ropes 72 to move synchronously, further pulling all the compression springs 73, causing them to be further compressed, and all the clamping columns 62 will also slide synchronously into the chute 61. When the clamping column 62 is fully inserted into the chute 61, the clamping column 62 separates from the clamping groove 63, thereby releasing the lock between the annular plate 2 4 and the annular plate 1 3. The operator can then remove the annular plate 2 4 and the filter element 5 together, making the disassembly between the annular plate 2 4 and the annular plate 1 3 more convenient and quick.

[0030] Further, refer to Figure 4 and Figure 5 The slot edge of the slot 63 is a transition chamfer 631. An end of the clamping column 62 away from the compression spring 73 is provided with a guide slope 621 that is inclined upward.

[0031] After the annular plate 2 4 is removed from the annular plate 1 3 , the operating lever 75 is loosened. Then, under the action of the compression spring 73 , all the clamping columns 62 will pop out from the sliding grooves 61 . When the filter element 5 is further fixed to the bottom of the annular plate 2 4, the annular plate 2 4 is coaxially placed on the annular plate 1 3. At this time, the guide inclined surface 621 of the clamping post 62 will first abut against the annular docking plate 1 32 of the annular plate 1 3, and the staff will press the annular plate 2 4 again. At this time, the component force of the force of the annular docking plate 1 32 on the guiding inclined surface 621 of the clamping post 62 will cause the clamping post 62 to slowly retract into the sliding groove 61. When the clamping post 62 is completely retracted into the sliding groove 61, the annular plate 2 4 is further pressed until the annular plate 2 4 is completely abutted against the annular plate 1 3, and then the annular plate 2 4 is rotated. When the clamping post 62 is rotated to the position of the clamping groove 63, the clamping post 62 will immediately be clamped in the clamping groove 63 under the action of the compression spring 73, and a "click" sound will be emitted. In this way, the fixing between the annular plate 2 4 and the annular plate 1 3 is completed under the cooperation of the clamping post 62 and the clamping groove 63. In this way, the installation of the filter element 5 is completed, and the entire installation process is also relatively simple and convenient.

[0032] On the whole, by setting the adjusting member 7, a plurality of slots 63 are opened on the outer wall of the annular docking plate 1 32, and a plurality of slide grooves 61 are opened on the inner wall of the annular docking plate 2 42, and a clamping column 62 is slidably set in each slide groove 61. The adjusting member 7 is used to synchronously adjust the movement of all the clamping columns 62, so that the fixation between the annular plate 1 3 and the annular plate 2 4 can be quickly released. During installation, it is only necessary to coaxially place the annular plate 2 4 on the annular plate 1 3, then press the annular plate 2 4, and rotate the annular plate 2 4 so that all the clamping columns 62 can be synchronously clamped in the slots 63, without the need for one-to-one alignment, thereby improving the overall convenience of disassembly and assembly of the filter element 5.

[0033] Reference Figure 2 As a specific implementation of the embodiment of the present application, a limiting groove 9 is opened at the end of the arc-shaped adjustment groove 82.

[0034] In combination with the specific usage scenario, when removing the filter element 5, after pushing the operating rod 75 along the arc-shaped adjustment groove 82 to the position of the limit groove 9, the operating rod 75 can be clamped into the limit groove 9, and the position of the operating rod 75 can be fixed using the limit groove 9, so that the annular plate 2 4 can be easily removed, further improving the convenience of disassembly of the annular plate 2 4 and the filter element 5.

[0035] Reference Figure 2 - Figure 7 As a specific implementation of the embodiment of the present application, a plurality of balls 100 are installed on the top of the annular support plate 31, and an annular groove 101 is opened at the bottom of the annular docking plate 42, and the balls 100 abut against the annular groove 101.

[0036] Furthermore, a plurality of second balls 111 are mounted on the top of the first annular docking plate 32 , and a second annular groove 112 is provided at the bottom of the second annular support plate 41 , in which the second balls 111 abut.

[0037] In combination with specific usage scenarios, the cooperation between ball 100 and annular groove 101 as well as ball 2 111 and annular groove 2 112 will not only not hinder the rotation of annular plate 2 4, but also improve the support strength of annular plate 1 3 to annular plate 2 4 and filter element 5, thereby ensuring the stability of disassembly and assembly of filter element 5 and the support stability of annular plate 2 and filter element.

[0038] Reference Figure 1 and Figure 2 As a specific embodiment of the present application, the second annular docking plate 42 includes a mounting plate 421 and a base plate 422 fixed to the bottom of the mounting plate 421. The slide groove 61 is formed on the inner wall of the mounting plate 421, and the first annular groove 101 is formed on the bottom of the base plate 422. Furthermore, the mounting plate 421 and the second annular support plate 41, as well as the base plate 422 and the mounting plate 421, are fixedly connected using countersunk screws 12.

[0039] In combination with the specific usage scenario, the annular docking plate 2 42 is designed to be a mounting plate 421 and a base plate 422, and countersunk screws 12 are used to connect the mounting plate 421 to the annular support plate 2 41 and the base plate 422 to the mounting plate 421. This facilitates the overall disassembly and assembly of the annular plate 2 4 and the adjusting part 7, and thus facilitates the early assembly and later maintenance of the annular plate 2 4 and the adjusting part 7.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
