[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0026] Example 1

[0027] Reference Figures 1 to 8 This embodiment proposes a water pump that is easy to install and disassemble water inlet accessories, including a pump body 1 and a sand barrier 3. The pump body 1 mainly includes components such as a pump casing 15, a motor 16, and an impeller 17.

[0028] A water inlet 101 is provided at the front end of the pump body 1, and a water outlet 102 is also provided on the pump body 1. The sand screen 3 is detachably installed at the front end of the pump body 1, and is characterized in that the rear portion of the sand screen 3 has a limiting surface 201 abutting against the pump body 1, a first locking block 11 is provided at the front portion of the pump body 1, and a second locking block 202 abutting against the front side surface of the first locking block 11 is provided on the sand screen 3. When the sand screen 3 rotates relative to the pump body 1 until the first locking block 11 and the second locking block 202 are offset, the sand screen 3 can be removed forward relative to the pump body 1.

[0029] A resistance device capable of limiting the rotation of the sand separator 3 relative to the pump body 1 is provided between the first locking block 11 and the second locking block 202 .

[0030] As a preferred solution of the resistance device, the resistance device includes a groove 203 provided on the second locking block 202 , and a protrusion 111 provided on the first locking block 11 and inserted into the groove 203 .

[0031] In the above scheme, the sand filter 3 can be installed and removed by screwing, which is very convenient. Specifically, when the second locking block 202 is rotated to the front of the first locking block 11, the sand filter 3 can be fixed. When the second locking block 202 is rotated to a position offset from the first locking block 11, the two are separated, and the sand filter 3 can be removed at this time, which is convenient and quick. Compared with the plug-in installation method, the above scheme has a tighter connection, and no screws are needed, so there is no problem of screw rust, which is conducive to improving the service life.

[0032] In addition, the above-mentioned resistance device can also adopt other structural forms, for example, the positions of the above-mentioned groove 203 and the protrusion 111 are swapped. Another example is to use a magnetic device, through the suction device, the first locking block 11 and the second locking block 202 are adsorbed together to limit the rotation and separation of the two. Of course, the cost of the solution using a magnetic device will be higher than the cost of the combination of the groove 203 and the protrusion 111.

[0033] Furthermore, the pump body 1 is provided with a limit plate 12 that can abut against the second locking block 202 when the second locking block 202 rotates to the front of the first locking block 11. When the sand filter 3 is installed, when the second locking block 202 is screwed into place, the limit plate 12 will abut against the side of the second locking block 202, so that the convex portion 111 on the first locking block 11 is accurately inserted into the groove 203 of the second locking block 202.

[0034] Reference Figure 2 and Figure 8 The water pump further comprises a base 5 detachably mounted on the bottom of the pump body 1, a card slot 51 arranged along the front-back direction is provided on the base 5, a vertical plate 131 is provided on the bottom surface of the pump body 1, a horizontal plate 132 is provided at the lower end of the vertical plate 131, the vertical plate 131 and the horizontal plate 132 together form a push-card member, one end of the card slot 51 has an opening for the push-card member to be inserted therein, after the push-card member is inserted into the card slot 51, the horizontal plate 132 abuts against the lower surface of the base 5 to limit the base 5 from moving downward relative to the pump body 1. With such a structure, the base 5 and the pump body 1 can be assembled together by pushing and inserting, which is convenient and quick.

[0035] Furthermore, a plurality of foot pads 6 are detachably mounted on the base 5. The foot pad 6 is an elastic body, and includes a sole portion 61, a neck portion 62, and a head portion 63 arranged in sequence from bottom to top. The diameter of the sole portion 61 is larger than the diameter of the head portion 63, and the diameter of the head portion 63 is larger than the diameter of the neck portion 62. The base 5 is provided with a first through hole 52 and a second through hole 53, and a connecting groove 54 is provided between the first through hole 52 and the second through hole 53 to connect the two. The first through hole 52 can be clamped in the neck portion 62 of the foot pad 6 and can limit the sole portion 61 and the head portion 63 from passing through. The second through hole 53 can be passed through the head portion 63 and can limit the sole portion 61 from passing through. The connecting groove 54 can be interference-fitted with the neck portion 62 to limit the neck portion 62 from moving from the first through hole 52 to the second through hole 53. The method of installing the foot pad 6 is to first pass the head 63 of the foot pad 6 through the second through hole 53, and then apply sufficient thrust to make the neck 62 of the foot pad 6 pass through the above-mentioned connecting groove 54 and snap into the first through hole 52, so that the installation of the foot pad 6 is completed, which is convenient and quick. The process of removing the foot pad 6 is the opposite of the above process. No screws are required, which eliminates the problem of screw rust.

[0036] Example 2

[0037] Figures 9 and 10 Embodiment 2 of the utility model is disclosed. This embodiment has a similar structure to embodiment 1, and the only difference is that a bottom suction sleeve 4 is used to replace the above-mentioned sand isolation piece 3. The bottom suction sleeve 4 also has a second locking block 202 and a limiting surface 201. The loading and unloading method of the bottom suction sleeve 4 is exactly the same as the loading and unloading method of the above-mentioned sand isolation piece 3.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
