Description

Technical Field

[0001] This utility model relates to a filter element cover positioning structure installed on a water circuit board. Background Technology

[0002] Currently, the filter element is inserted into the water circuit board through the filter element cover. Since the plug of the water circuit board and the insertion rod of the filter element cover need to be sealed to ensure no water leakage, the insertion rod requires a lot of force to detach from the plug, making disassembly inconvenient. When the filter element is working, it will generate water hammer and produce a lot of vibration. The filter element cover needs to be firmly fixed to ensure that the filter element works normally. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a filter element cover positioning structure installed on the water circuit board. It allows the fastened insert rod to be loosened and the entire filter element to be pushed out more easily. The filter element cover is firmly fixed to ensure that the filter element works normally.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: it is a filter element cover positioning structure installed on a water circuit board, characterized by comprising: Water circuit board; a water circuit board plug is provided on the water circuit board; Pressure cap; the pressure cap is rotatably mounted on the water channel plate, and the pressure cap is provided with a push position, a press position and a barb locking position; and The filter element cover has an insert rod, a first protrusion, a second protrusion, and a pressure-bearing surface. The insert rod is inserted into the water circuit board plug. When the cover is rotated downwards, the barb latches onto the second protrusion, and the pressing position presses against the pressure-bearing surface, thereby positioning the filter element cover. When the cover is rotated upwards, the barb latches no longer latches onto the second protrusion, the pressing position does not press against the pressure-bearing surface, and the pushing position abuts against the first protrusion, thereby pushing the filter element cover to move.

[0005] In this embodiment, the pressure-bearing surface is L-shaped. When the pressure cap rotates downward, the lower pressure position presses against the horizontal surface of the pressure-bearing surface, and the inner sidewall of the pressure cap matches the longitudinal surface of the pressure-bearing surface.

[0006] In this embodiment, a hollowed-out position is provided on the pressure cap. When the pressure cap is rotated downwards, the upper part of the filter element cover is located in the hollowed-out position.

[0007] In this embodiment, a pressure-bearing inclined surface is provided on the filter element cover and between the first protrusion and the second protrusion, and a downward pressing inclined surface is provided on the pressure cap. When the pressure cap is rotated downward, the downward pressing inclined surface abuts against the pressure-bearing inclined surface.

[0008] In this embodiment, the water circuit board is provided with a mounting position with a shaft hole, and the pressure cover is provided with a rotating shaft. The rotating shaft is rotatably installed in the shaft hole of the mounting position, so that the pressure cover is rotatably installed on the water circuit board.

[0009] The advantages of this utility model compared with the prior art are: it allows the tightened insert rod to loosen and more easily push out the entire filter element, and the filter element cover is firmly fixed to ensure that the filter element works normally. Attached Figure Description

Detailed Implementation

[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0012] like Figures 1 to 4 The diagram shows a filter cartridge cover positioning structure installed on a water circuit board, comprising: Water circuit board 1; a water circuit board plug 11 is provided on the water circuit board 1; Pressure cap 3; the pressure cap 3 is rotatably mounted on the water channel plate 1, and the pressure cap 3 is provided with a push position 32, a press position 34 and a barb locking position 33; and The filter element cover 2 is provided with a rod 22, a first protrusion 23, a second protrusion 24 and a pressure-bearing surface 21. The rod 22 is inserted into the water circuit board plug 11. When the cover 3 is rotated downward, the barb 33 is engaged with the second protrusion 24 and the pressing position 34 presses against the pressure-bearing surface 21, thereby positioning the filter element cover 2. When the cover 3 is rotated upward, the barb 33 is not engaged with the second protrusion 24 and the pressing position 34 is not pressed against the pressure-bearing surface 21. The pushing position 32 abuts against the first protrusion 23, thereby pushing the filter element cover 2 to move.

[0013] When in use, the insert rod 22 is inserted into the water circuit board plug 11. When the filter element is rotated downwards by the pressure cap 3, the barb lock 33 is fastened to the second protrusion 24 to prevent the filter element cover 2 from moving outwards, thereby preventing the insert rod 22 from dislodging from the water circuit board plug 11. The pressing position 34 presses against the pressure bearing surface 21 to press the filter element cover 2 and position the filter element. When the filter element is rotated upwards by the pressure cap 3, the pressing position 34 does not press against the pressure bearing surface 21, and the pushing position 32 abuts against the first protrusion 23 to move the filter element cover 2 outwards. The insert rod 22 also moves outwards, thereby loosening the insert rod 22 and facilitating the removal of the filter element.

[0014] In this embodiment, the pressure-bearing surface 21 is L-shaped. When the pressure cap 3 is rotated downward, the lower pressure position 34 presses against the horizontal surface of the pressure-bearing surface 21, and the inner sidewall of the pressure cap 3 cooperates with the longitudinal surface of the pressure-bearing surface 21.

[0015] In this embodiment, a hollowed-out position 36 is provided on the pressure cap 3. When the pressure cap 3 is rotated downward, the upper part of the filter element cover 2 is located in the hollowed-out position 36, and the upper part of the filter element cover 2 abuts against the inner wall of the hollowed-out position 36.

[0016] In this embodiment, a pressure-bearing inclined surface 25 is provided on the filter element cover 2 and between the first protrusion 23 and the second protrusion 24, and a downward pressing inclined surface 35 is provided on the pressure cover 3. When the pressure cover 3 is rotated downward, the downward pressing inclined surface 35 abuts against the pressure-bearing inclined surface 25.

[0017] In this embodiment, the water circuit plate 1 is provided with a mounting position 12 with a shaft hole, and the pressure cover 3 is provided with a rotating shaft 31. The rotating shaft 31 is rotatably installed in the shaft hole of the mounting position 12, so that the pressure cover 3 is rotatably installed on the water circuit plate 1.

[0018] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations of these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
