Abstract
Description
Technical Field
[0001] This application relates to the field of sanitary ware technology, and in particular to a lifting mechanism for use in toilets. Background Technology
[0002] As people's living standards improve, the functions of smart toilets are becoming increasingly powerful. A smart toilet typically includes a toilet body, a base, control components, and a lid. The base is fixed to the toilet body, and the control components and lid are located on the base. Smart toilets have blind spots covered by the base. Because the base cannot move relative to the toilet body, users cannot clean these blind spots, which over time become unsanitary and result in a poor user experience. Utility Model Content
[0003] In view of the above problems, this application provides a lifting mechanism for toilets that overcomes or at least partially solves the above problems.
[0004] According to one aspect of this application, a lifting mechanism for a toilet is provided for connecting a toilet body and a base. The mechanism includes a housing, a lifting member, a limiting member, a movable member, and a first elastic member. The housing is disposed on the toilet body. The lifting member is movably disposed on the housing, and the base is disposed on the lifting member. The limiting member is disposed on the lifting member. The movable member is movably disposed on the housing and can move relative to the housing between a first position and a second position to lock and unlock the limiting member. The first elastic member is disposed on the movable member and is used to return the movable member from the second position to the first position. When the movable member is in the first position, it can be locked with the limiting member to restrict the movement of the lifting member. When the movable member moves from the first position to the second position, it is unlocked from the limiting member, and the lifting member can move relative to the housing. When the force driving the movable member is released, the movable member returns from the second position to the first position under the force of the first elastic member.
[0005] In some embodiments, the limiting member has a first opening, and the movable member has a locking part. When the movable member is in a first position, the locking part can be inserted into the first opening to lock the movable member with the limiting member. When the movable member moves from the first position to a second position, the locking part disengages from the first opening, thereby releasing the locking between the movable member and the limiting member.
[0006] In some embodiments, there are two first openings and two movable members, with the two first openings and the two movable members arranged opposite each other, and the locking portions of the two first openings and the two movable members corresponding one-to-one. A first elastic member is located between the two movable members, and the two movable members can return from the second position to the first position under the force of the first elastic member.
[0007] In some embodiments, the housing has a second opening, and the portion of the movable member with a locking portion is slidably disposed in the second opening.
[0008] In some embodiments, the device further includes a pusher and a connector. The pusher is slidably disposed on the housing, one end of the connector is rotatably disposed on the pusher, and the other end of the connector is rotatably disposed on the movable member. During the pressing of the pusher, the pusher drives the movable member via the connector, causing the movable member to move from a first position to a second position. When the pusher is not pressed, the movable member returns from the second position to the first position under the force of a first elastic member, and simultaneously drives the pusher back to its pre-pressed position via the connector.
[0009] In some embodiments, the housing is provided with a first slide rail, and the pusher includes a first sliding portion and a first limiting portion connected together. The first sliding portion is slidably disposed on the first slide rail, and one end of the connecting member is rotatably disposed on the first limiting portion. The housing includes a first wall connected to the first slide rail, and the first wall is provided with a third opening. A portion of the first sliding portion is located in the third opening, and the first limiting portion and the first slide rail are respectively located on both sides of the first wall. The first limiting portion protrudes from the first sliding portion. When the pusher returns to its position before being pressed, the first limiting portion abuts against the first wall.
[0010] In some embodiments, the housing is provided with a stop portion, which abuts against the movable member when the movable member moves from the first position to the second position.
[0011] In some embodiments, the housing is provided with a second slide rail, and the lifting member includes a connected second sliding portion and a first connecting portion. The second sliding portion is slidably disposed on the second slide rail and can slide relative to the second slide rail between a third position and a fourth position. A limiting member is disposed on the first connecting portion. When the movable member is in the first position and the second sliding portion is in the third position, the movable member and the limiting member are locked. When the movable member and the limiting member are unlocked, the second sliding portion can slide from the third position to the fourth position.
[0012] In some embodiments, the limiting member includes a second connecting portion and a second limiting portion connected together. The second connecting portion is disposed on the first connecting portion. The housing includes a second wall connected to a second slide rail. The second wall has a fourth opening. A portion of the second connecting portion and / or a portion of the first connecting portion is located in the fourth opening. The second limiting portion and the second sliding portion are respectively located on both sides of the second wall. The second limiting portion protrudes from the second connecting portion. When the second sliding portion slides from a third position to a fourth position, the second limiting portion abuts against the second wall.
[0013] In some embodiments, a second elastic member is further provided between the second sliding portion and the second wall, and the second sliding portion can slide from the third position to the fourth position under the force of the second elastic member.
[0014] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a lifting mechanism for a toilet, used to connect the toilet body and the base. It includes a housing, a lifting member, a limiting member, a movable member, and a first elastic member. The housing is disposed on the toilet body. The lifting member is movably disposed on the housing, and the base is disposed on the lifting member, allowing the base to move relative to the toilet body. The limiting member is disposed on the lifting member. The movable member is movably disposed on the housing and can move relative to the housing between a first position and a second position to lock and unlock the limiting member. The first elastic member is disposed on the movable member, used to return the movable member from the second position to the first position. When the movable member is in the first position, it can lock with the limiting member to restrict the movement of the lifting member, thereby restricting the movement of the base relative to the toilet body, keeping the base and toilet body fixed. When the movable part moves from the first position to the second position, it releases the locking member from the limiting member, allowing the lifting member to move relative to the housing. This allows the base to move relative to the toilet body, exposing the blind spot area covered by the base, which the user can then clean, thus improving the user experience. When the force driving the movable part is released, it returns from the second position to the first position under the force of the first elastic member. After cleaning, the user can return the base to its original position. When the limiting member returns to its original position with the base, it locks with the movable part, fixing the toilet body and the base in place. The lifting mechanism of this application allows the base to move relative to the toilet body to expose the blind spot area covered by the base when cleaning is needed, and keeps the base and toilet body fixed when cleaning is not required.

[0018] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.
[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0020] A smart toilet typically includes a toilet body, a base, control components, and a top cover. The base is fixed to the toilet body, and the control components and top cover are located on the base. Smart toilets have blind spots covered by the base. Since the base cannot move relative to the toilet body, users cannot clean these blind spots, which over time become unsanitary and result in a poor user experience.
[0021] The lifting mechanism of this application can move the base relative to the toilet body to expose the blind corner area covered by the base when the toilet needs to be cleaned, and keep the base and the toilet body fixed when the toilet does not need to be cleaned.
[0022] Please see Figure 1-2 This application proposes a toilet 100, including a toilet body 101, a base 102, a lifting mechanism 10, a control component (not shown) and a top cover 103. The lifting mechanism 10 connects the toilet body 101 and the base 102, and the control component and the top cover 103 are disposed on the base 102.
[0023] To facilitate the reader's understanding of the concept of this utility model, the specific structure of the lifting mechanism 10 applied to the toilet 100 is described below: Please refer to the following: Figure 3-6The lifting mechanism 10 connects the toilet body 101 and the base 102, and includes a housing 1, a lifting member 2, a limiting member 3, a movable member 4, and a first elastic member 5. The housing 1 is disposed on the toilet body 101. The lifting member 2 is movably disposed on the housing 1, and the base 102 is disposed on the lifting member 2, so that the base 102 can move relative to the toilet body 101. The limiting member 3 is disposed on the lifting member 2. The movable member 4 is movably disposed on the housing 1 and can move relative to the housing 1 between a first position and a second position to lock and unlock the limiting member 3. The first elastic member 5 is disposed on the movable member 4 and is used to return the movable member 4 from the second position to the first position. When the movable member 4 is in the first position, the movable member 4 can be locked with the limiting member 3 to restrict the movement of the lifting member 2, thereby restricting the movement of the base 102 relative to the toilet body 101, and the base 102 and the toilet body 101 remain fixed. When the movable part 4 moves from the first position to the second position, the movable part 4 is unlocked from the limiting part 3, and the lifting part 2 can move relative to the housing 1, so that the base 102 can move relative to the toilet body 101, thereby exposing the dead corner area of the toilet 100 covered by the base 102. The user can clean this dead corner area, thereby improving the user experience. When the force driving the movable part 4 is released, the movable part 4 returns from the second position to the first position under the action of the first elastic part 5. After the user finishes cleaning, the base 102 can be returned to its original position. When the limiting part 3 returns to its original position along with the base 102, it can lock with the movable part 4, so that the toilet body 101 and the base 102 are fixed. The lifting mechanism 10 of this application can move the base 102 relative to the toilet body 101 to expose the dead corner area covered by the base 102 when the toilet 100 needs to be cleaned, and keep the base 102 and the toilet body 101 fixed when the toilet 100 does not need to be cleaned.
