Specifically, the pressure tank 20 is used as a water storage device of the water purifier 1, so that the purified water purified by the water purifier 1 can be stored in the pressure tank 20, thereby being convenient for users to use. The components such as the filter element and the water pump of the water purifier 1 are installed in the shell 10, meanwhile, a containing cavity 100 with an opening 101 is formed on the shell 10, wherein the opening 101 can be positioned at the top end of the shell 10 or on the side wall of the shell 10, and the pressure tank 20 is contained in the containing cavity 100 in a drawable mode. It will be appreciated that when the opening 101 is located at the top end of the housing 10, the pressure tank 20 is loaded into the accommodating chamber 100 in the up-down direction or is withdrawn from the accommodating chamber 100; when the opening 101 is located at the side wall of the case 10, the pressure tank 20 is horizontally loaded into the accommodating chamber 100 or is withdrawn from the accommodating chamber 100; of course, in some other embodiments, the pressure tank 20 is disposed obliquely in the housing 10, and a certain angle may be formed between the drawing direction of the pressure tank 20 and the horizontal plane.

In order to facilitate the pulling of the pressure tank 20, the pressure tank 20 is mounted on the handle 30, and the handle 30 is movably connected with the pressure tank 20, for example, the handle 30 may rotate or slide relative to the pressure tank 20, which is not limited herein. It should be noted that, when the pressure tank 20 is pulled or the pressure tank 20 is placed in the accommodating cavity 100, the handle 30 needs to move relative to the pressure tank 20, so as to facilitate the handheld operation of the user.

According to the technical scheme, the handle 30 is movably arranged on the pressure tank 20, and the handle 30 is detachably connected with the cavity wall of the accommodating cavity 100, so that when the pressure tank 20 is placed in the accommodating cavity 100, the handle 30 moves relative to the pressure tank 20 to be connected with the cavity wall of the accommodating cavity 100, the handle 30 can be prevented from being misoperation, and further the pressure tank 20 is prevented from being mistakenly touched and pulled, so that the pressure tank 20 and related waterways are prevented from being damaged, and the working reliability of the water purifier 1 is ensured; in addition, since the handle 30 is connected to the wall of the accommodating chamber 100, the pressure tank 20 is limited to the accommodating chamber 100, and the assembling structure between the pressure tank 20 and the housing 10 is more stable.

In this embodiment, the opening 101 of the receiving chamber 100 is preferably located at the top end of the housing 10. The accommodating chamber 100 also preferably extends in the up-down direction, and the pressure tank 20 may be loaded into the accommodating chamber 100 from the opening 101 in the up-down direction or may be withdrawn from the accommodating chamber 100 from the opening 101. In the process of installing the pressure tank 20, the pressure tank 20 can slide into the accommodating cavity 100 by means of self gravity, so that the pressure tank 20 is more labor-saving and convenient to assemble.

Further, the handle 30 is preferably rotatably connected to the pressure tank 20, wherein the handle 30 includes a holding section 310 and a connecting section 320 extending from two ends of the holding section 310, one end of the connecting section 320 away from the holding section 310 is provided with a rotating shaft, and two opposite sides of the pressure tank 20 are respectively provided with mounting holes for the rotating shaft to be rotatably inserted. The handle 30 is generally U-shaped, and the rotating shaft is disposed on one side of the two connecting sections 320 facing each other, so that the handle 30 rotates relative to the pressure tank 20, thereby facilitating the handheld operation of the user.

The top end of the pressure tank 20 is provided with a containing groove 201 corresponding to the handle 30, the groove wall of the containing groove 201 is provided with a mounting hole, and the handle 30 can rotate relative to the pressure tank 20 to be movably contained in the containing groove 201. By providing the receiving groove 201, when the user puts down the pressure tank 20, the handle 30 can be rotated into the receiving groove 201.

In order to facilitate the user to pull out the handle 30 from the accommodating groove 201, the top end of the pressure tank 20 is provided with a handle groove 202 at least corresponding to a part of the holding section 310, and the handle groove 202 is communicated with the accommodating groove 201. Thus, the user can insert fingers or tools into the handle groove 202, so as to conveniently take the hand-held section 310 out of the accommodating groove 201, and facilitate the holding operation of the hand on the handle 30.

Various connection manners between the handle 30 and the cavity wall of the accommodating cavity 100 are provided, for example, the handle 30 and the cavity wall of the accommodating cavity 100 may be connected by a screw locking manner or a snap connection, and the following description will specifically explain a connection structure between the handle 30 and the cavity wall of the accommodating cavity 100 in a preferred embodiment of the present invention:

for the handle 30, a limiting portion 321 is convexly disposed on a side of the connecting section 320 facing away from the pressure tank 20, a sliding groove 102 slidably matched with the limiting portion 321 is disposed on a cavity wall of the accommodating cavity 100, the sliding groove 102 includes a clamping section 105 and an introducing section 106, one end of the introducing section 106 is communicated with the opening 101, and the other end is communicated with one end of the clamping section 105;

when the pressure tank 20 is loaded into the accommodating cavity 100 from the opening 101, the limiting part 321 slides in the introducing section 106; when the handle 30 rotates relative to the pressure tank 20, the limiting portion 321 rotates from the guiding section 106 to the clamping section 105.

It will be appreciated that when the user lifts the pressure tank 20, the handle 30 rotates to a vertical state relative to the pressure tank 20, when the pressure tank 20 is installed in the accommodating cavity 100, the limiting portion 321 slides down along the guiding section 106, after the pressure tank 20 is installed in place, the handle 30 is rotated at this time, so that the handle 30 rotates to a horizontal state relative to the pressure tank 20 (when the handle 30 is accommodated in the accommodating groove), the limiting portion 321 rotates along with the handle 30, and then the limiting portion 321 rotates from the guiding section 106 to the clamping section 105. In this way, the limiting portion 321 is clamped and fixed in the clamping section 105, so that the lifting handle 30 can be prevented from being touched by mistake and rotated and lifted again, and the pressure tank 20 can be firmly limited in the accommodating cavity.

It should be emphasized that, the limiting portion 321 is located at one end of the connecting section 320 away from the holding section 310, when the user operates the holding section 310 to rotate the handle 30, a lever effect is formed, and the fulcrum of the lever is the contact position between the limiting portion 321 and the chute 102, so that when the user operates the holding section 310, the moment of the acting force is larger, and then the limiting portion 321 can rotate from the guiding section 106 into the clamping section 105 with smaller force.

Further, in this embodiment, the groove wall of the introducing section 106, which is close to the opening 101, is convexly provided with a limiting buckle 103 toward the direction of the pressure tank 20, the cavity wall of the accommodating cavity is provided with an elastic arm 104, and the limiting buckle 103 is located at the free end of the elastic arm 104;

a limiting groove 322 is formed in one side, opposite to the connecting section 320, of the limiting portion 321, and when the pressure tank 20 is installed into the accommodating cavity 100 from the opening 101, the limiting buckle 103 is in sliding buckling connection with the limiting groove 322; when the handle 30 rotates relative to the pressure tank 20, the limiting groove 322 can rotate relative to the limiting buckle 103, so that the limiting groove 322 is separated from the limiting buckle 103.

It can be appreciated that, by providing the limit groove 322 and the limit buckle 103, when the pressure tank 20 is installed in the accommodating cavity 100, the pressure tank 20 is subject to the action of self gravity, the limit buckle 103 can be easily clamped into the limit groove 322, and during the downward movement of the pressure tank 20, the limit groove 322 moves downward relative to the limit buckle 103; when the pressure tank 20 is installed in place, the handle 30 rotates relative to the pressure tank 20, at this time, the limiting groove 322 rotates with the limiting part 321, so that the limiting groove 322 is separated from the limiting buckle 103, and the limiting part 321 is located below the limiting buckle 103, at this time, the limiting buckle 103 can limit the rotation of the limiting part 321, so that the limiting part 321 is firmly limited in the clamping section 105, and the pressure tank 20 is further limited in the accommodating cavity 100.

When it is desired to withdraw the pressure tank 20 from the receiving chamber 100, the user operates the hand-held portion 310 of the handle 30, and the user can rotate the handle 30 with respect to the pressure tank 20 in a labor-saving manner due to the leverage effect. In the process of rotating the handle 30, the limiting portion 321 and the limiting groove 322 rotate along with the handle 30, at this time, the limiting groove 322 rotates upwards, so that the limiting groove 322 is matched with the limiting buckle 103 again, the limiting portion 321 can rotate from the clamping section 105 to the guiding section 106 again, the limiting portion 321 is convenient to separate from the sliding groove 102, separation of the handle 30 and the cavity wall of the accommodating cavity 100 is achieved, and the pressure tank 20 is convenient to draw out of the accommodating cavity 100.

In order to facilitate the up-and-down movement of the limiting groove 322 relative to the limiting buckle 103, the limiting groove 322 extends along the length direction of the connecting section 320, and at this time, the limiting groove 322 can ensure the sliding fit between the limiting buckle 103 and the limiting groove 322 during movement, so that a certain guiding effect is realized, and the limiting part 321 can better move up and down in the guiding section 106.

It can be understood that when the pressure tank 20 slides in place in the accommodating cavity 100, the limiting portion 321 is located at the bottom end of the introducing section 106, and the limiting buckle 103 is relatively located at one end of the limiting groove 322 close to the holding section 310, when the groove width of the limiting groove 322 is smaller, when the limiting groove 322 rotates along with the limiting portion 321, the limiting buckle 103 can be conveniently separated from the limiting groove 322, so as to release the limiting buckle 103 and the limiting clamping groove. Similarly, when the pressure tank 20 needs to be pulled, the limit buckle 103 can be conveniently buckled into the limit groove 322, which is not described in detail herein. Therefore, in the present embodiment, the groove width of the limiting groove 322 is reduced in a direction from the free end of the connecting section 320 toward the hand-holding section 310.

Similarly, in order to facilitate the release of the limit buckle 103 from the limit groove 322, or the buckling of the limit buckle 103 into the limit groove 322, the groove depth of the limit groove 322 is tapered in a direction from the free end of the connecting section 320 toward the hand-held section 310. At this time, the shallower the groove depth of the limit groove 322, the easier the limit buckle 103 is to be disengaged from the limit groove 322, or the easier the limit buckle 103 is to be buckled into the limit groove 322.

In order to facilitate the limiting portion 321 to achieve a better supporting point effect, in this embodiment, the limiting portion 321 extends along the length direction of the connecting section 320, and the width of the limiting portion 321 is reduced in the direction from the free end of the connecting section 320 toward the hand-held section 310. Thus, the limiting part 321 has a structure with one large end and one lower end, and the larger end of the limiting part 321 is in contact with the groove wall surface of the clamping section 105, so that the contact area can be increased, and the rotation of the limiting part 321 can be realized more easily through the lever effect.

Further, in order to facilitate the rotation of the limiting portion 321, the end of the limiting portion 321 is smoothly transited, so as to reduce the friction between the limiting portion 321 and the wall of the chute 102 during the rotation. Preferably, for the chute 102, the groove wall at the connection part of the guiding section 106 and the clamping section 105 is smooth, and the groove wall at the end part of the clamping section 105 can also be smooth, so that the friction force between the limiting part 321 and the groove wall of the chute 102 is further reduced.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
