Abstract
Description
Technical Field
[0001] This application relates to the field of liquid containers, and more particularly to a liquid container. Background Technology
[0002] Currently, liquid containers on the market do not have the function of sliding or rolling along the table. Users can only move the liquid container by lifting it, which makes it difficult for users to move large-capacity liquid containers filled with liquid, and is inconvenient to use. Utility Model Content
[0003] This application provides a liquid container that solves the problem of inconvenient movement of liquid containers in the prior art.
[0004] This application provides a liquid container, comprising: a container body; and a rolling device installed on the outer bottom wall of the container body. The rolling device includes an outer cover and a rolling element. The outer cover and the outer bottom wall of the container body form a receiving space. The rolling element is installed within the receiving space. The outer cover has a communicating hole, and a portion of the rolling element extends out to the outside through the communicating hole. When the liquid container is placed on a supporting surface, the rolling element contacts the supporting surface, so that the liquid container can form a rolling contact with the supporting surface through the rolling element.
[0005] In the above solution, when the liquid container is placed on a supporting surface (such as a table or the ground), if the user moves the liquid container along the supporting surface, the rolling element can roll relative to the outer cover, creating rolling contact between the liquid container and the supporting surface. Therefore, by setting a rolling device on the outer bottom wall of the container, the frictional resistance between the liquid container and the supporting surface can be reduced, making it easier for the user to move the liquid container. Especially for large-capacity liquid containers filled with water, the rolling device makes it easier for users to move the liquid container without lifting it; they only need to pull or push the liquid container along the supporting surface, improving the user experience. Moreover, since the rolling element is located on the outside of the container, if the rolling element is damaged, only the outer cover needs to be removed to replace it with a new one, facilitating maintenance and inspection.
[0006] In one possible design, the outer bottom wall of the container body is provided with a mounting groove, the rolling device is fixedly installed in the mounting groove, and the outer bottom wall of the outer cover is flush with the outer bottom wall of the container body.
[0007] In the above scheme, when the liquid container is placed on the support surface, both the outer cover and the outer bottom wall of the container body can contact the support surface, thereby increasing the contact area between the container body and the support surface, which is beneficial to improving the stability of the liquid container when placed on the support surface.
[0008] In one possible design, the rolling device further includes an inner cover connected to the outer cover, the inner cover and the outer cover forming a limiting space, and the rolling element is installed within the limiting space.
[0009] In the above scheme, the inner cover and the outer cover can limit the rolling element along the axial direction of the container body, which helps to improve the installation stability of the rolling element, ensures that the part of the rolling element extending to the outside can always make contact with the support surface, ensures that the rolling device can work normally, and thus improves the reliability of the rolling device.
[0010] In one possible design, the inner cover has a limiting groove on one side surface facing the limiting space, and at least a portion of the rolling element is located within the limiting groove.
[0011] In the above scheme, the limiting groove can play a limiting role in the circumferential direction of the rolling element, preventing the rolling element from shifting relative to the connecting hole, thereby further improving the installation stability of the rolling element.
[0012] In one possible design, the rolling element is a ball, the inner wall of the limiting groove is a first arc surface, and the ball forms a rolling contact with the first arc surface.
[0013] In the above scheme, as the liquid container moves relative to the supporting surface, the ball can form rolling contact with the first arc surface to reduce the frictional resistance between the ball and the limiting groove, making the rolling process of the ball smoother. Moreover, the arc surface structure helps to improve the limiting effect of the limiting groove on the ball, thereby further improving the installation stability of the ball.
[0014] In one possible design, the rolling element is a ball, the inner wall of the connecting hole is a second arc surface, and the ball forms a rolling contact with the second arc surface.
[0015] In the above scheme, as the liquid container moves relative to the supporting surface, the ball can form rolling contact with the second arc surface to reduce the frictional resistance between the ball and the connecting hole, making the rolling process of the ball smoother. In addition, the second arc surface can also support and limit the ball, which helps to improve the installation reliability and rolling stability of the ball.
[0016] In one possible design, one of the sidewalls of the inner cover and the outer cover is provided with a groove, and the other is provided with a protrusion, and the groove and the protrusion are engaged and fixed.
[0017] In the above solution, the slot and the protrusion are engaged and fixed so that the inner cover and the outer cover can form limiting fits in the axial and radial directions of the container body, thereby improving the connection reliability between the inner cover and the outer cover. Moreover, the structure of the slot and the protrusion fitting together is relatively simple, easy to manufacture and easy to install.
[0018] In one possible design, at least a portion of the inner cover is located inside the outer cover, and at least one of the outer sidewall of the inner cover and the inner sidewall of the outer cover is provided with a guide ramp.
[0019] In the above scheme, the guide slope facilitates quick positioning of the inner and outer covers during assembly, and also facilitates the guide fit between the side walls of the inner and outer covers during the installation process, which helps to improve the assembly efficiency of the inner and outer covers.
[0020] In one possible design, the inner cover and / or the outer cover are bonded and fixed to the outer bottom wall of the container body.
[0021] Of the above solutions, the adhesive bonding method is easier to operate and helps to improve the reliability of the connection between the rolling device and the container body.
[0022] In one possible design, the outer cover has a ring structure, and a plurality of the rolling elements are spaced apart in the circumferential direction of the outer cover.
[0023] In the above solution, on the one hand, the simultaneous action of multiple rolling elements can further reduce the frictional resistance between the liquid container and the supporting surface, improving the rolling fit between the liquid container and the supporting surface. On the other hand, the rolling elements at the bottom of the container can support the container body. When multiple rolling elements are distributed at intervals on the annular outer cover, the supporting force on the container body can be more uniform, improving the stability of the liquid container when placed on the supporting surface.

[0045] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation
[0046] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0047] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0048] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0049] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0050] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.
[0051] This application provides a liquid container for holding liquids. Specifically, the liquid container can be an electric kettle with a heating function or a kettle with only a heat preservation function; this embodiment does not impose any limitations on this. Figure 1 As shown, the liquid container includes a container body 1 and a rolling device 2. The rolling device 2 is installed on the outer bottom wall of the container body 1, and the rolling device 2 includes at least an outer cover 21 and a rolling element 22. Figure 2 As shown, the outer cover 21 is used to form a receiving space 23 with the outer bottom wall of the container body 1. The rolling element 22 is installed in the receiving space 23. The outer cover 21 is provided with a connecting hole 211, which is connected to the receiving space 23 and the outside. Part of the rolling element 22 can extend to the outside along the connecting hole 211.
[0052] When the liquid container is placed on a supporting surface (such as a table or the ground), the portion of the rolling element 22 extending to the outside can contact the supporting surface. If the user moves the liquid container along the supporting surface, the rolling element 22 can roll relative to the outer cover 21, creating a rolling contact between the liquid container and the supporting surface. Therefore, by providing the rolling device 2 on the outer bottom wall of the container body 1, the frictional resistance between the liquid container and the supporting surface can be reduced, making it easier for the user to move the liquid container. Especially for large-capacity liquid containers filled with water, the rolling device 2 allows users to move the liquid container with less effort, eliminating the need to lift it; they only need to pull or push it along the supporting surface, improving the efficiency of liquid container movement and thus enhancing the user experience. Furthermore, in this embodiment, the rolling element 22 is located on the outside of the container body 1. If the rolling element 22 is damaged, only the outer cover 21 needs to be removed to replace it with a new one, facilitating maintenance and inspection.
[0053] In one specific implementation, such as Figure 1As shown, the outer cover 21 has a ring-shaped structure, with multiple rolling elements 22 spaced apart around its circumference. On one hand, the simultaneous action of multiple rolling elements 22 further reduces the frictional resistance between the liquid container and the supporting surface, improving the rolling fit between them. On the other hand, the rolling elements 22 at the bottom of the container body 1 provide support. When multiple rolling elements 22 are spaced apart on the ring-shaped outer cover 21, the supporting force on the container body 1 becomes more uniform, improving the stability of the liquid container when placed on the supporting surface.
[0054] In one specific embodiment, the outer bottom wall of the container body 1 can be a planar structure, and the rolling device 2 is installed on the outer bottom wall of the container body 1 by adhesive bonding. In this case, the outer cover 21 protrudes relative to the outer bottom wall of the container body 1. When the liquid container is placed on the supporting surface, the outer cover 21 contacts the supporting surface to support the container body.
[0055] Or, combine Figure 2 and Figure 3 As shown, in another embodiment, the outer bottom wall of the container body 1 is provided with a mounting groove 11, the rolling device 2 is fixedly installed in the mounting groove 11, and the outer bottom wall of the outer cover 21 is flush with the outer bottom wall of the container body 1. Compared with the aforementioned embodiment where the outer cover 21 protrudes relative to the outer bottom wall of the container body 1, when the liquid container is placed on the support surface, both the outer cover 21 and the outer bottom wall of the container body 1 can contact the support surface, thereby increasing the contact area between the container body 1 and the support surface, which is beneficial to improving the stability of the liquid container when placed on the support surface. In this embodiment, the shape and size of the mounting groove 11 are adapted to the outer cover; when the outer cover 21 is an annular structure, the mounting groove 11 is also an annular structure.
[0056] The following describes the specific structure of the rolling device 2, taking the example of a container body 1 having an installation groove 11 on its outer bottom wall and a rolling device 2 fixedly installed in the installation groove 11.
[0057] In one specific implementation, such as Figure 2 As shown, the rolling device 2 also includes an inner cover 24 connected to the outer cover 21. The inner cover 24 is located within the receiving space 23, and the inner cover 24 and the outer cover 21 form a limiting space 25, in which the rolling element 22 is installed. At this time, the inner cover 24 and the outer cover 21 can limit the rolling element 22 along the axial direction Z of the container body 1, which helps to improve the installation stability of the rolling element 22, ensures that the part of the rolling element 22 extending to the outside can always form contact with the supporting surface, ensures that the rolling device 2 can work normally, and thus improves the reliability of the rolling device 2.
[0058] Furthermore, such as Figure 2As shown, a limiting groove 241 is provided on the side surface of the inner cover 24 facing the limiting space 25. At least a portion of the rolling element 22 is located in the limiting groove 241. The limiting groove 241 can limit the rolling element 22 in the circumferential direction, preventing the rolling element 22 from shifting relative to the connecting hole 211, thereby further improving the installation stability of the rolling element 22.
[0059] In this embodiment, the rolling element 22 can specifically be a ball bearing or a swivel caster. When the rolling element 22 is a ball bearing, such as... Figure 4 As shown, the inner wall of the limiting groove 241 is a first arc surface 241a that matches the ball bearing. During the movement of the liquid container relative to the support surface, the ball bearing can form rolling contact with the first arc surface 241a, reducing the frictional resistance between the ball bearing and the limiting groove 241, thus making the rolling process of the ball bearing smoother. Furthermore, the arc surface structure helps to improve the limiting effect of the limiting groove 241 on the ball bearing, thereby further improving the installation stability of the ball bearing.
[0060] It should be noted that the radius of curvature of the first arc surface 241a should be greater than or equal to the radius of curvature of the ball to ensure that the limiting groove 241 does not affect the rolling process of the ball.
[0061] Similarly, such as Figure 4 As shown, the inner wall of the connecting hole 211 can be configured as a second arc surface 211a that matches the ball bearing. During the movement of the liquid container relative to the support surface, the ball bearing can form a rolling contact with the second arc surface 211a to reduce the frictional resistance between the ball bearing and the connecting hole 211, making the rolling process of the ball bearing smoother. In addition, the second arc surface 211a can also support and limit the ball bearing, which helps to improve the installation reliability and stability of the ball bearing during the rolling process.
[0062] It should be noted that the radius of curvature of the second arc surface 211a should be greater than or equal to the radius of curvature of the ball to ensure that the connecting hole 211 does not affect the rolling process of the ball.
[0063] In this embodiment, the ball bearing can be made of plastic, glass, or stainless steel, or other materials, and there are no restrictions on this.
[0064] In one specific implementation, such as Figure 4 As shown, the inner cover 24 is fastened to the top of the outer cover 21. One side wall of the inner cover 24 and the other side wall of the outer cover 21 are provided with a groove 242, and the other side wall is provided with a protrusion 212. The groove 242 and the protrusion 212 engage and fix the inner cover 24 and the outer cover 21, allowing them to form limiting fits in the axial direction Z and radial direction X of the container body 1, respectively, thereby improving the reliability of the connection between the inner cover 24 and the outer cover 21. Furthermore, the structure of the groove 242 and the protrusion 212 is relatively simple, easy to manufacture, and easy to install.
[0065] like Figure 4 As shown, specifically, the side wall of the inner cover 24 can extend into the interior of the outer cover 21 to form a fixed connection with the outer cover 21. That is, a slot 242 can be provided on the outer side wall of the inner cover 24, and a protrusion 212 can be provided on the inner side wall of the outer cover 21. The side wall of the inner cover 24 can be inserted into the outer cover 21 along the axial direction Z of the container body 1, thereby achieving the snap-fit fixation between the slot 242 and the protrusion 212. Alternatively, a protrusion 212 can be provided on the outer side wall of the inner cover 24, and a slot 242 can be provided on the inner side wall of the outer cover 21. The installation method is the same as the aforementioned structure.
[0066] Furthermore, guide slopes 243 can be provided on at least one of the outer side wall of the inner cover 24 and the inner side wall of the outer cover 21. This facilitates quick positioning of the inner cover 24 and the outer cover 21 during assembly and also facilitates the formation of a guiding fit between the side walls of the inner cover 24 and the outer cover 21 during installation, thereby improving the assembly efficiency of the inner cover 24 and the outer cover 21. To facilitate the snap-fit engagement between the slot 242 and the protrusion 212, the inner cover 24 and the outer cover 21 are preferably made of elastically deformable plastic, specifically ABS plastic.
[0067] In another embodiment, the side wall of the outer cover 21 may extend into the interior of the inner cover 24 and form a fixed connection with the inner cover 24. That is, a slot 242 may be provided on one of the inner side wall of the inner cover 24 and the outer side wall of the outer cover 21, and a protrusion 212 may be provided on the other. The specific installation and mating method is the same as the aforementioned embodiment, and will not be described again here.
[0068] In one specific embodiment, the installation process of the rolling device 2 is as follows: first, the rolling element 22 is placed into the limiting groove 241 of the inner cover 24 (or, the rolling element 22 is placed into the communicating hole 211 of the outer cover 21), then the outer cover 21 and the inner cover 24 are snapped together to form a complete rolling device 2, and finally the rolling device 2 is bonded and fixed to the mounting groove 11, which helps to improve the connection reliability between the rolling device 2 and the container body 1. Specifically, adhesive can be applied only to the outer wall of the inner cover 24, adhesive can be applied only to the outer wall of the outer cover 21, or adhesive can be applied to both the outer walls of the inner cover 24 and the outer walls of the outer cover 21. This embodiment does not limit this.
[0069] In this embodiment, the inner cover 24 may be omitted. Instead, a limiting part with the same structure as the inner cover 24 may be provided on the top wall of the mounting groove 11. The outer cover 21 is fixedly connected to the limiting part. The limiting part can cooperate with the outer cover 21 along the axial direction Z of the container body 1 to limit the rolling element 22.
[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
