[0059] Specifically, in Figure 2 In the embodiment, a water outlet is provided on the left side of the water outlet body 101 extending laterally, and a connecting component is provided at the lower end of the supporting body extending vertically. In other embodiments, the main unit 1 may be of other shapes. The shape of the main unit 1 is introduced here only for the convenience of explaining the position of the water outlet. One end of the inner water pipe 2 is detachably fixed to the connecting component, so as to be detachably connected to the outer water pipe 4 of the water pump. That is to say, through the connecting component, the inner water pipe 2 and the outer water pipe 4 of the water pump are detachable and connected. When the water pump is working normally, the inner water pipe 2 is connected to the outer water pipe 4 to realize the pumping function. When the water pump is cleaned, the inner water pipe 2 and the outer water pipe 4 are removed from the connecting component for cleaning. In addition, the other end of the inner water pipe 2 is connected to the water outlet, and it can be detachably fixed to the water outlet.

[0060] In addition, the inner water pipe 2 can be a hard pipe or a soft rubber pipe. For the convenience of fixing, the middle part of the inner water pipe 2 can be fixed to the main unit 1 by means of snap connection, magnetic attraction, sliding groove, lock, latch, thread fastening, elastic clip or gluing. For example, the inner accommodating cavity 103 of the main unit 1 is further provided with a clamping portion 108 for fixing the inner water pipe 2, and the clamping portion 108 can detachably clamp the inner water pipe 2.

[0061] In the above embodiment, the inner water pipe 2 and the outer water pipe 4 are separated by a connecting component, one end of the inner water pipe 2 is detachably connected to the water outlet, and the other end is detachably connected to the connecting component, thereby realizing the detachability of the inner water pipe 2, and when the water pump is working normally, the inner water pipe 2 is connected to the outer water pipe 4 through the connecting component to realize the water pumping function.

[0062] For convenience, the inner water pipe 2 in the present application can be directly detachably fixed in the main unit 1, or the inner water pipe 2 can be first detachably fixed to a cover member, and the cover member can be detachably fixed to the main unit 1, so that the inner water pipe 2 can be detachably fixed through the cover member.

[0063] In one embodiment, when the inner water pipe 2 is directly and detachably fixed to the main unit 1, a water pipe fixing component 304 is provided at one end of the main unit 1 near the water outlet of the water pump, and one end of the inner water pipe 2 is detachably fixed to the main unit 1 through the water pipe fixing component 304, so that the water outlet end of the inner water pipe 2 at least partially protrudes outward from the main unit 1. The water pipe fixing component 304 can be a component for realizing snap connection, magnetic attraction, slide groove, lock, latch, threaded fastening, elastic clip or adhesive. Correspondingly, an installation cavity is provided on the connecting component, and the inner water pipe 2 is detachably inserted into the installation cavity, and is detachably connected to the outer water pipe 4 through the outer water pipe 4 connector inserted into the installation cavity. Specifically, the installation cavity can be in the direction of the outer water pipe 4, and a small installation cavity is also sleeved in the installation cavity, and the inner water pipe 2 is detachably inserted into the small installation cavity, and the outer water pipe 4 is inserted into the installation cavity, and is sleeved or inserted into the small installation cavity to realize the communication between the inner water pipe 2 and the outer water pipe 4.

[0064] In addition, the middle part of the inner water pipe 2 can be fixed to the main unit 1 by means of snap connection, magnetic attraction, sliding groove, lock, latch, threaded fastening, elastic clip or gluing.

[0065] Preferably, when the inner water pipe 2 can be directly and detachably fixed in the main unit 1, a receiving cavity 103 is provided on the main unit 1, and the inner water pipe 2 is arranged in the receiving cavity 103; a body opening 104 connected to the receiving cavity 103 is provided on the main unit 1; a cover body assembly 3 for opening or closing the body opening 104 is provided on the main unit 1; when the body opening 104 is opened, the inner water pipe 2 is at least partially exposed to the body opening 104, so that the user can disassemble the inner water pipe 2.

[0066] In this way, the water pump has a body opening 104 on the surface of the main body 1, and the body opening 104 is opened or closed by the cover body assembly 3. The user can open the body opening 104 by removing the cover body assembly 3, and then remove the inner water pipe in the accommodating cavity for cleaning or maintenance. On the one hand, it can effectively ensure the user's drinking water health, and on the other hand, it can extend the service life of the water pump.

[0067] In an embodiment in which the inner water pipe 2 is first detachably fixed to a cover member, and the cover member is detachably fixed to the main unit 1, so that the inner water pipe 2 is detachable through the cover member, hereinafter referred to as an embodiment in which the inner water pipe 2 is indirectly detachable, the water pump may include the cover assembly 3 and the corresponding structure described above, which will not be repeated here.

[0068] Further, the inner water pipe 2 is detachably or non-detachably fixed to the cover assembly 3. When the cover assembly 3 closes the body opening 104, the inner water pipe 2 is fixed to the main unit 1 and connected to the outer water pipe 4 of the water pump through the connecting component. When the cover assembly 3 opens the body opening 104, the inner water pipe 2 is removed from the connecting component on the main unit 1. The inner water pipe 2 can be a hard pipe or a soft rubber pipe. For easy fixation, the middle part of the inner water pipe 2 can also be fixed to the cover assembly 3 by means of snap connection, magnetic attraction, slide groove, lock buckle, latch, threaded fastening, elastic clip or gluing.

[0069] Specifically, combined Figure 8 As shown, the inner water pipe 2 is detachably or non-detachably fixed to the cover assembly 3, so that the inner water pipe 2 can be replaced or cleaned by replacing the cover assembly 3 or replacing the inner water pipe 2 on the cover assembly 3.

One end of the inner water pipe 2 is detachably fixed to the cover through the fixing component 304 , and the other end is detachably inserted into the positioning boss 305 .

[0071] Specifically, the fixing component 304 can be two pairs of protrusions symmetrically arranged, and the distance between each pair of protrusions corresponds to the width of the embedded component on the inner water pipe 2, so that by inserting the embedded component of the inner water pipe 2 between each pair of protrusions, one end of the inner water pipe 2 can be fixed to one end of the cover assembly 3, that is, the end corresponding to the water outlet of the host 1, and the inner water pipe 2 partially extends out of the cover assembly 3, thereby ensuring the normal outflow of water. The other end of the inner water pipe 2 can be detachably inserted into the positioning boss 305, so that the inner water pipe 2 can be inserted into the connecting component through the positioning boss 305, thereby realizing the detachability of the inner water pipe 2.

[0072] In one embodiment, multiple parts of the inner water pipe 2 are integrally formed and fixed together on the cover assembly 3. In other embodiments, the inner water pipe 2 can also be divided into multiple parts, namely, a water outlet part, a middle part and a water inlet part, wherein the water outlet part can be directly detachably fixed to the cover assembly 3 through a fixing member 304, the middle part can be inserted into the water outlet part, the water inlet part can also be detachably connected to the middle part, and the water inlet part can be detachably fixed to the positioning boss 305. In addition, it should be noted that in the embodiment where the inner water pipe 2 is directly fixed to the host 1, the inner water pipe 2 can also be integrally formed or divided into multiple parts, which will not be repeated here.

[0073] In one embodiment, the cover assembly 3 includes a cover plate 301 , and the cover plate 301 is fixed to the host 1 by means of a buckle, a clamp buckle or a lock buckle to cover the body opening 104 .

[0074] in Figure 7 The cover is fixed to the host 1 by means of a clamp-shaped buckle, and the lock buckle is opened by pushing up the button through an inclined wedge. Figure 8 The cover is fixed to the host 1 by means of plastic buckles.

[0075] Furthermore, the cover assembly 3 includes a cover plate 301 and a locking component 302 ; the cover plate 301 opens or closes the body opening 104 ; the locking component 302 is disposed on the inner side of one end of the cover plate 301 , and the cover plate 301 is locked and connected to the host 1 via the locking component 302 .

[0076] Furthermore, the locking component 302 is elastically reset and movably arranged on the inner side of one end of the cover plate 301, and a locking tongue 3024 is integrally formed on one side or both sides of the bottom end of the locking component 302; a locking groove 105 corresponding to the locking tongue 3024 is provided at the bottom end of the host 1; when the locking tongue 3024 is inserted into the locking groove 105, the cover body assembly 3 is locked and connected to the host 1; when the locking tongue 3024 is disengaged from the locking groove 105, the cover body assembly 3 can be disassembled and separated from the host 1.

[0077] Furthermore, the locking component 302 is slidably disposed on the inner side of the bottom end of the cover plate 301 , and an elastic member 303 is disposed between the locking component 302 and the cover plate 301 , and the elastic member 303 acts on the locking component 302 to elastically slide on the cover plate 301 . Specifically, the elastic member 303 is a spiral columnar spring; the cover plate 301 is provided with a first limiting role part 3013, a first anti-slip part 3014 and a guide groove 3015; the locking component 302 is provided with a second limiting role part 3021, a second anti-slip part 3022 and a guide extension 3025; the elastic member 303 elastically acts between the first limiting role part 3013 and the second limiting role part 3021, so that the elastic member 303 acts on the locking component 302 to elastically slide on the cover plate 301; when the locking component 302 elastically resets and slides to the set position relative to the cover plate 301, the first anti-slip part 3014 and the second anti-slip part 3022 abut against each other to prevent the locking component 302 from sliding excessively relative to the cover plate 301 and falling out; the guide extension 3025 slides in the guide groove 3015, thereby effectively guiding the locking component 302 to slide linearly on the cover plate 301.

[0078] Furthermore, a mounting cavity 106 for mounting and connecting an opening of a water storage container (the water storage container may be barreled water, bottled water, etc.) is provided at the bottom of the main unit 1. The mounting cavity 106 is closed at the top, open at the bottom, and provided with an avoidance notch 107 on the side. At least when the cover assembly 3 is connected to the main unit 1, the unlocking action portion 3023 at the middle of the bottom end of the locking component 302 is exposed at the avoidance notch 107, so that the user can slide the locking component 302 in the unlocking direction through the unlocking action portion 3023, so that the main unit 1 and the cover assembly 3 can be detached.

[0079] Furthermore, a buckle 3011 is provided on the inner side of the other end of the cover plate 301, and at least when the cover body assembly 3 is connected to the host 1, the buckle 3011 is buckled with the outer shell of the host 1; one end of the cover body assembly 3 is buckled with the host 1 through the buckle 3011, and the other end is locked with the host 1 through the locking component 302, so that the cover body assembly 3 as a whole can be firmly and reliably assembled on the host 1, and the cover body assembly 3 can be detached from the host 1 as a whole. Alternatively, a hinge structure is provided between the other end of the cover plate 301 and the host 1, and the cover plate 301 is hinged to the host 1 through the hinge structure; that is, one end of the cover body assembly 3 is hinged to the host 1 through the hinge structure, and the other end is locked with the host 1 through the locking component 302, so that the cover body assembly 3 as a whole can be firmly and reliably assembled on the host 1, and the cover body assembly 3 opens the body opening 104 in a swinging manner.

[0080] Furthermore, a boss 1041 is provided on the edge of the body opening 104; a convex edge 3012 is provided on the edge of the cover assembly 3. At least when the cover assembly 3 is connected to the host 1, the boss 1041 cooperates with the convex edge 3012 to make the cooperation between the body opening 104 and the cover assembly 3 better.
