It should be noted that "axial direction" hereinafter refers to the mounting direction of the pump body 100 and the fixing base 200, and "radial direction" refers to the direction perpendicular to the axial direction.

The embodiment discloses an air conditioner drainage pump, referring to fig. 1, fig. 2 and fig. 3, including a pump body 100 and a fixing seat 200, wherein:

the top of the pump body 100 is provided with a plurality of radial bosses 110 protruding in the radial direction;

the fixed seat 200 is arranged at the top of the pump body 100; the bottom of the fixed seat 200 is provided with a plurality of buckles 210 protruding along the axial direction, and the buckles 210 are used for being buckled with the radial bosses 110; the surface of the buckle 210 is provided with a reinforcing cushion block 213 extending along the axial direction, and the length of the reinforcing cushion block 213 in the axial direction is greater than that of the buckle 210; the reinforcing pad 213 can slide back and forth in the axial direction with respect to the buckle 210; the bottom of the fixed seat 200 is further provided with a plurality of axial bosses 220 protruding in the axial direction, and the axial bosses 220 are all embedded between the adjacent radial bosses 110; the axial boss 220 is used for limiting the circumferential rotation of the fixing seat 200;

both sides of the radial boss 110 are provided with stoppers 120, and the stoppers 120 are used for limiting the circumferential rotation of the clip 210.

The clip 210 may be made of any one of high toughness plastic selected from PET plastic, ABS plastic, TPU plastic, TPE plastic and TPEE plastic.

When the fixing base 200 is installed to the pump body 100 from top to bottom, the buckle 210 is hindered by the radial boss 110 to deform the buckle 210 outward along the radial direction, and after the fixing base 200 continues to move downward until the buckle 210 completely crosses the radial boss 110, the buckle 210 is buckled at the bottom of the radial boss 110 under the action of the deformation restoration, so that the fixing base 200 and the pump body 100 are installed.

The buckle 210 is buckled on the rear two sides of the radial boss 110 and is attached to the stop block 120, when the fixing seat 200 is stressed in the circumferential direction, because the two sides of the buckle 210 are stopped by the stop block 120, the fixing seat 200 cannot rotate under the action of external force, and the phenomenon that the drainage pump is affected by vibration after being installed and fixed to cause deviation between mechanisms is effectively avoided.

When the fixing base 200 and the pump body 100 are frequently assembled and disassembled, the snap 210 may be permanently deformed, so that the contact area between the snap 210 and the stoppers 120 on both sides is reduced, and the snap 210 is separated from the stoppers 120 when receiving a circumferential external force. Therefore, a plurality of axial bosses 220 are arranged at the bottom of the fixed seat 200, the inner diameter of the axial bosses 220 is larger than or equal to the outer diameter of the pump body 100, and the outer diameter of the axial bosses 220 is smaller than or equal to the radial height of the stop block 120. Because the axial boss 220 does not need to deform when the fixing base 200 is mounted on the pump body 100, the contact area between the axial boss 220 and the stop block 120 does not change under the frequent assembling and disassembling condition of the fixing base 200 and the pump body 100, and the blocking effect between the axial boss 220 and the stop block 120 is ensured, so that the circumferential relative movement between the fixing base 200 and the pump body 100 is ensured, and the fixing strength between the fixing base 200 and the pump body 100 is further improved.

It should be noted that, the axial boss 220 is arc-shaped, the plurality of axial bosses 220 are arranged at intervals along the circumferential direction of the fixing base 200, the inner diameter of the axial boss 220 refers to the diameter of the inner wall surface (the diameter of the inner arc surface) of the axial boss 220, and the outer diameter of the axial boss 220 refers to the diameter of the outer wall surface (the diameter of the outer arc surface) of the axial boss 220.

In addition, the thickness of axial boss 220 is greater than buckle 210, compare in buckle 210, axial boss 220 possesses higher structural strength, when the junction between pump body 100 and fixing base 200 receives the shearing force, buckle 210's structure is not enough to bear too big effort, buckle 210 breaks away from easily along circumference and leads to air conditioner drain pump structure to damage, or lead to pump body 100 to break away from fixing base 200, consequently set up the higher axial boss 220 of intensity in order to bear the shearing force, avoid air conditioner drain pump structure to damage, effectively ensure the fixed effect of fixing base 200 and pump body 100 simultaneously.

In practical applications, the buckle 210 needs to deform outward in the radial direction during the process of buckling on the radial boss 110, and when the pump body 100 and the fixing base 200 are assembled and disassembled for many times, the buckle 210 may be permanently deformed, so that the buckle 210 is bent, and the connection strength between the buckle 210 and the radial boss 110 is reduced.

In this embodiment, the reinforcing mat 213 has a certain rigidity and may be made of metal, hard plastic, or the like.

The reinforcing pad 213 is used to cover the blocking clip 210, so as to deform the blocking clip 210 in the radial direction, and also reinforce the structural strength of the blocking clip 210, share the force in the circumferential direction and the shearing force, and prevent the clip 210 from being broken. When the pump body 100 and the fixing seat 200 are installed, a user pulls the reinforcing cushion block 213 upwards to enable the reinforcing cushion block 213 to be far away from the buckle 210 (the reinforcing cushion block 213 does not cover the surface of the buckle 210), and at the moment, the buckle 210 can deform along the radial direction, so that the fixing seat 200 can be smoothly buckled and fixed on the pump body 100; after the pump body 100 and the fixing base 200 are assembled, the reinforcing cushion block 213 is shifted downwards, so that the reinforcing cushion block 213 covers the surface of the buckle 210, because the reinforcing cushion block 213 has certain rigidity, the buckle 210 is blocked by the reinforcing cushion block 213 (the reinforcing cushion block 213 presses the buckle 210 to enable the buckle 210 to be always buckled and connected on the radial boss 110), so that the buckle 210 can be firmly buckled on the radial boss 110, the permanent deformation of the buckle 210 is effectively prevented from generating, so that the connection strength between the buckle 210 and the radial boss 110 is reduced, meanwhile, the reinforcing cushion block 213 covers the surface of the buckle 210, when the buckle 210 receives the circumferential direction acting force and the shearing acting force, part of the acting force can be distributed on the reinforcing cushion block 213, so that the buckle 210 is protected, and the buckle 210 is effectively prevented from being broken.

In some preferred embodiments, the reinforcing pad block 213 is further provided with a toggle member, the toggle member is fixedly connected with the reinforcing pad block 213, and a hand of a user applies an acting force on the toggle member, so that the user can move the reinforcing pad block 213 through the toggle member; meanwhile, the buckle 210 is fixed with two blocking pieces in the axial direction, the blocking pieces are used for limiting the radial movement of the reinforcing cushion block 213 to prevent the reinforcing cushion block 213 from separating from the buckle 210, and the stirring piece is located between the two blocking pieces and slides back and forth along the axial direction along with the reinforcing cushion block 213 between the two blocking pieces (the upper blocking piece is also used for limiting the highest point of the movement of the reinforcing cushion block 213, and the lower blocking piece is also used for limiting the lowest point of the movement of the reinforcing cushion block 213 and simultaneously supporting the stirring piece to prevent the reinforcing cushion block 213 from falling along the axial direction).

In some possible embodiments, a sliding groove extending in the axial direction may be provided on the catch 210, and the reinforcement pad 213 is mounted on the sliding groove to slide back and forth in the axial direction on the surface of the catch 210.

In some preferred embodiments, referring to fig. 2, 3 and 5, the bottom of the buckle 210 is provided with a first inclined surface 211; the upper part of the radial boss 110 is provided with a second inclined plane 111; the buckle 210 is buckled at the bottom of the radial boss 110 after sliding through the second inclined surface 111 by the first inclined surface 211. The buckle 210 is deformed outwards along the radial direction under the mutual guiding action of the first inclined plane 211 and the second inclined plane 111, and the first inclined plane 211 slides away from the second inclined plane 111 and then is buckled at the bottom of the radial boss 110 under the acting force generated by the deformation recovery.

In practical applications, when the fixing base 200 is installed, the snap 210 must be aligned with the radial boss 110 to be accurately snapped on the bottom of the radial boss 110. Therefore, in some possible embodiments, the snap 210 may not be aligned exactly with the radial boss 110, so that the snap 210 is not successfully snapped on the bottom of the radial boss 110.

In certain preferred embodiments, referring to fig. 3 and 5, the top of the stopper 120 is provided with a curved surface 121; the bottom of the stopper 120 is provided with a third slope 122. The arc 121 and the third inclined surface 122 are used for guiding when the snap 210 is not aligned with the radial boss 110. When the clip 210 moves from top to bottom, the clip 210 can smoothly deform outward in the radial direction under the guiding action of the arc surface 121 even if the clip 210 is not completely aligned with the radial boss 110; the buckle 210 further moves downwards and then passes through the third inclined plane 122, the outer diameter of the upper part of the third inclined plane 122 is larger than the outer diameter of the lower part, the third inclined plane 122 is inclined towards the central axis integrally, the buckle 210 slides downwards along the third inclined plane 122 under the action force generated by deformation recovery, but the buckle 210 is not buckled at the bottom of the radial boss 110 at the moment, so when the buckle 210 slides downwards along the third inclined plane 122, a user rotates the buckle 210 along the direction close to the radial boss 110 by twisting with a small amplitude, and finally the buckle 210 is separated from the third inclined plane 122 and buckled at the bottom of the radial boss 110, thereby completing the whole installation process. The arrangement of the arc surface 121 and the third inclined surface 122 allows a user to smoothly complete the installation between the fixed seat 200 and the pump body 100 even when the fastener 210 is not aligned with the radial boss 110, thereby greatly reducing the installation difficulty.

In certain preferred embodiments, referring to fig. 2 and 3, the outer surface of the clip 210 is further provided with a rib 212. As described in the above embodiment, when the fixing base 200 is assembled with and disassembled from the pump body 100, the clip 210 is deformed, the clip 210 can be effectively prevented from being repeatedly deformed to cause fracture by the arrangement of the reinforcing ribs 212, the resilience of the deformed clip 210 can be improved to a certain extent, the risk of permanent deformation of the clip 210 is effectively reduced, and the service life of the clip 210 is greatly prolonged.

In certain preferred embodiments, referring to fig. 1, the number of snaps 210 is less than or equal to the number of radial bosses 110, and each snap 210 is snap-connected to one radial boss 110. The user can adjust the circumferential position between fixing base 200 and the pump body 100 according to the installation, and rethread buckle 210 is fixed, further improves the suitability of air conditioner drain pump under different installation scenes.
