Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a water supply device. Background Technology
[0002] A water dispenser is a device installed at the opening of a bottled water container to draw water from it, and it is very convenient for daily use. However, existing water dispensers have significant limitations on the size of the water container opening and cannot be adapted to various different sizes of water container openings, thus limiting their use. Utility Model Content
[0003] This application provides a water inlet device that can be adapted to various sizes of water bucket openings, has fewer limitations in use, and improves the user experience.
[0004] This application provides a water supply device, which includes at least two grippers, a base, and a drive turntable.
[0005] The base is provided with a first through hole, which extends radially along the base, and the gripper is slidably connected to the first through hole;
[0006] The drive turntable is provided with a guide hole, which extends radially inclined relative to the base;
[0007] At least a portion of the gripper is accommodated within the guide hole. During the rotation of the drive turntable relative to the base, the inner wall of the guide hole is used to drive the gripper to slide along the first through hole to adjust the radial position of the gripper on the base.
[0008] In this solution, users can control the grippers simply by rotating the drive turntable, thus adapting to containers with different opening sizes. The structure is simple, the operation is easy, and the user experience is improved.
[0009] Optionally, the base is provided with a rotating shaft. A second through hole is provided at the center of the drive turntable, and the rotating shaft passes through the second through hole so that the drive turntable can rotate around the rotating shaft.
[0010] In this design, the rotating shaft on the base engages with the second through hole on the drive turntable, allowing the drive turntable to rotate around the rotating shaft. The rotating shaft acts as a limit for the drive turntable, preventing it from shifting or tilting, thus improving the stability of the drive turntable during rotation. This ensures that the drive turntable can stably drive the gripper to slide along the first through hole through the guide hole, thereby improving the sliding stability of the gripper.
[0011] Optionally, the outer sidewall of the rotating shaft is provided with a protrusion, and the sidewall of the second through hole abuts against the protrusion along the radial direction of the rotating shaft.
[0012] During the rotation of the drive turntable around the rotating shaft, the sidewall of the second through hole can slide along the protrusion.
[0013] In this design, on the one hand, the protrusion improves the motion stability of the drive turntable when it rotates along the axis, thereby enhancing the connection reliability between the gripper and the container. On the other hand, the protrusion is of moderate size and will not affect the rotation of the drive turntable along the axis.
[0014] Optionally, the gripper includes a clamping part and a limiting part, and the clamping part is fixedly connected to the limiting part.
[0015] The clamping part passes through the first through hole and the guide hole, and is slidably connected to the first through hole and the guide hole respectively. The limiting part overlaps on the side surface of the drive turntable away from the base, and the limiting part can cooperate with the drive turntable to restrict the axial movement of the gripper along the water supply device.
[0016] In this design, the separable clamping and limiting parts facilitate the installation of the grippers through the first through hole and the guide hole.
[0017] Optionally, the clamping part includes a main body part, which is slidably connected to the first through hole.
[0018] The main body is provided with a limiting plane. During the sliding of the main body along the first through hole, the inner wall of the first through hole and the limiting plane are limited and engaged along the width direction of the first through hole.
[0019] In this design, the inner wall of the first through hole and the limiting plane are matched in a limiting manner along the width direction of the first through hole, which improves the motion stability of the gripper when it slides along the first through hole.
[0020] Optionally, the clamping part further includes a guide part fixedly connected to the main body, and the guide part is slidably connected to the guide hole.
[0021] The guide part is provided with a guide arc surface. During the rotation of the drive turntable relative to the base, the inner wall of the guide hole slides in cooperation with the guide arc surface, so that the guide part drives the main body to slide along the first through hole.
[0022] In this design, the guide section has a guide arc surface that slides with the inner wall of the guide hole, which improves the motion stability of the gripper when it slides along the guide hole.
[0023] Optionally, the base is further provided with limiting ribs. At least two of the grippers are distributed circumferentially along the limiting ribs, and a receiving space is formed between the end of the gripping portion away from the limiting portion and the limiting rib.
[0024] In this design, the limiting rib extends into the opening of the adapter container, serving as a guide and positioning element for the container's opening. Simultaneously, when the water supply device tilts, the inner wall of the container's opening will abut against the limiting rib, restricting the water supply device from continuously tilting. This improves the installation stability of the water supply device and enhances the reliability of the fit between the water supply device and the container.
[0025] Optionally, a guide slope is provided at the end of the clamping portion away from the limiting portion. Along the radial direction of the base, the guide slope is located on the side surface of the clamping portion facing the limiting rib.
[0026] In this design, a guide slope is provided on the side of the clamping part facing the limiting rib, which improves the clamping stability and positioning accuracy of the gripper, facilitates the gripper to clamp the mouth of the container, and also improves the connection reliability between the water supply device and the adapter container.
[0027] Optionally, the outer wall of the drive turntable is provided with anti-slip protrusions.
[0028] In this design, the anti-slip protrusions evenly distributed along the outer wall of the drive turntable provide ample points for the user to apply force as the drive turntable rotates along the axis. When the user rotates the drive turntable, the anti-slip protrusions increase the friction between the drive turntable and the user's fingers, making it less likely for the user's fingers to slip when applying force, thus facilitating operation and improving the user experience.
[0029] Optionally, the water supply device further includes a cover, which is fixedly connected to the base by fasteners.
[0030] The drive turntable is located between the cover and the base, and the drive turntable is provided with a clearance through hole, through which the fastener passes.
[0031] In this design, the cover and base are fixedly connected by fasteners, improving the stability of the connection between them. The drive turntable is equipped with clearance holes to avoid the fasteners, preventing them from affecting the rotational movement of the drive turntable relative to the base, thereby improving the motion stability of the drive turntable.

[0064] 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.
[0065] 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.
[0066] 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.
[0067] 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, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0068] This application provides a water supply device, such as... Figure 1 and Figure 2 As shown, the water supply device includes at least two grippers 1, a base 2, and a drive turntable 3. Figures 3 to 6 As shown, the base 2 is provided with a first through hole 21, which extends radially along the base 2, and the gripper 1 is slidably connected to the first through hole 21. The drive turntable 3 is provided with a guide hole 31, which extends radially inclined relative to the base 2.
[0069] Specifically, in this embodiment, the number of grippers 1 can be 3. In other embodiments, the specific number of grippers 1 can also be 2, 4, 6, etc. This application does not limit the specific number of grippers 1. The number of first through holes 21 and the number of guide holes 31 are equal to the number of grippers 1, that is, grippers 1 are respectively provided in a one-to-one correspondence with the first through holes 21 and guide holes 31.
[0070] At least a portion of the gripper 1 is accommodated in the corresponding guide hole 31. During the rotation of the drive turntable 3 relative to the base 2, the inner wall of the guide hole 31 is used to drive the gripper 1 to slide along the first through hole 21 to adjust the position of the gripper 1 in the radial direction of the base 2.
[0071] Each gripper 1 can slide along the first through hole 21 under the driving action of its corresponding guide hole 31, allowing all grippers 1 to move closer or further apart. When the grippers 1 approach each other to their minimum distance, the grippers 1 are in a position as follows: Figure 3 or Figure 5 The first position shown; when the grippers 1 are far apart from each other to their maximum distance, the grippers 1 are in the position shown. Figure 4 or Figure 6 The second position is shown. By controlling the rotation angle of the drive turntable 3, the positions of all grippers 1 can be adjusted synchronously so that the grippers 1 can be in any position between the first position and the second position. That is, the water supply device in this embodiment can adapt to containers with opening sizes within the range of the first position to the second position. For example, the container can be a water bucket.
[0072] In this embodiment, the user can control the gripper 1 simply by rotating the drive turntable 3, thereby adapting to containers with different opening sizes. The structure is simple, the operation is easy, and the user experience is improved.
[0073] In some embodiments, such as Figure 9 As shown, the inner wall of the guide hole 31 has a first surface 311 and a second surface 312. The second surface 312 is used to drive the gripper 1 from... Figure 3 The first position shown is rotated to Figure 4 The second position shown in the diagram drives the turntable 3 to rotate along the first direction X during this process; the first surface 311 is used to drive the claw from... Figure 4 The second position shown is rotated to Figure 3 The first position is shown, during which the drive turntable 3 rotates along the second direction Y.
[0074] It should be noted that the second direction Y is the opposite direction of the first direction X. In this embodiment, the first direction X is specifically the counterclockwise direction, and the second direction Y is specifically the clockwise direction.
[0075] Preferably, the water supply device in this example can be adapted to containers with an opening diameter in the range of 30mm-58mm, which includes the diameter sizes of commonly used containers adapted to water supply devices on the market.
[0076] In some embodiments, such as Figure 3 and Figure 4 As shown, the base 2 is provided with a rotating shaft 22. A second through hole 32 is provided at the center of the drive turntable 3, and the rotating shaft 22 passes through the second through hole 32 so that the drive turntable 3 can rotate around the rotating shaft 22.
[0077] In this embodiment, the rotating shaft 22 on the base 2 cooperates with the second through hole 32 on the drive turntable 3, so that the drive turntable 3 can rotate around the rotating shaft 22. The rotating shaft 22 can limit the drive turntable 3, preventing the drive turntable 3 from deviating or tilting, thus improving the stability of the drive turntable 3 during rotation. This ensures that the drive turntable 3 can stably drive the gripper 1 to slide along the first through hole 21 through the guide hole 31, thereby improving the sliding stability of the gripper 1.
[0078] In some embodiments, such as Figure 3 and Figure 4 Combination Figure 8 As shown, the outer wall of the rotating shaft 22 is provided with a protrusion 221, and the side wall of the second through hole 32 abuts against the protrusion 221 in the radial direction of the rotating shaft 22; during the process of driving the turntable 3 to rotate around the rotating shaft 22, the side wall of the second through hole 32 can slide along the protrusion 221.
[0079] Specifically, the contact between the protrusion 221 and the second through hole 32 generates a certain amount of resistance during the rotation of the drive turntable 3 along the shaft 22, and this resistance value is relatively small. On the one hand, without applying external force to drive the drive turntable 3, the drive turntable 3 can stably maintain a certain position without reversing under the action of resistance. That is, when the gripper 1 is adjusted to the designated position, the gripper 1 can stably cooperate with the container, reducing the risk of shaking. On the other hand, when the drive turntable 3 needs to rotate, only sufficient external force needs to be applied to overcome the resistance to realize the rotation of the drive turntable 3, thereby realizing the adjustment of the gripper 1.
[0080] In this embodiment, the specific structure of the protrusion 221 can be circular protrusions evenly spaced along the rotation axis 22. In other embodiments, the protrusion 221 can also be corrugated protrusions or other structures. This application does not limit the specific structure of the protrusion 221. The number of protrusions 221 is at least two, specifically two, three, four, five or more, and this embodiment does not limit the specific number of protrusions 221. At least two protrusions 221 are evenly spaced along the circumference of the rotation axis 22 to ensure that the drive turntable 3 can rotate at a uniform speed under the action of external force, thereby improving the stability of the drive turntable 3 during rotation.
[0081] In this embodiment, by providing a protrusion 221 on the rotating shaft 22, on the one hand, the motion stability of the drive turntable 3 when rotating along the rotating shaft 22 is improved, thereby improving the connection reliability when the gripper 1 engages with the container. On the other hand, the protrusion 221 is of moderate size and will not affect the rotation of the drive turntable 3 along the rotating shaft 22.
[0082] In some embodiments, such as Figures 3 to 6 Combination Figure 7As shown, the gripper 1 includes a gripping part 11 and a limiting part 12, and the gripping part 11 and the limiting part 12 are fixedly connected.
[0083] Specifically, in this embodiment, the clamping part 11 and the limiting part 12 can be two separable parts. The specific cooperation method between the clamping part 11 and the limiting part 12 can be a snap-fit, and after the clamping part 11 and the limiting part 12 are snapped together, they will provide a certain rigid constraint to each other, preventing the two parts from moving relative to each other. In other embodiments, the cooperation method between the clamping part 11 and the limiting part 12 can also be a snap-fit connection, a bolt connection, or other structures. This application does not limit the cooperation method between the clamping part 11 and the limiting part 12.
[0084] The clamping part 11 passes through the first through hole 21 and the guide hole 31, and is slidably connected to the first through hole 21 and the guide hole 31 respectively. The limiting part 12 overlaps on the side surface of the drive turntable 3 away from the base 2, and the limiting part 12 can cooperate with the drive turntable 3 to limit the axial movement of the gripper 1 along the water supply device.
[0085] Specifically, the clamping part 11 is used to clamp the container opening adapted to the water supply device of this embodiment, and the limiting part 12 is used to limit the surface of the drive turntable 3 to restrict the gripper 1 from moving downward along the axial direction of the water supply device, thereby preventing the gripper 1 from coming out of the guide hole 31 and the first through hole 21, improving the movement stability of the gripper 1 when sliding along the first through hole 21 and the guide hole 31, and improving the installation reliability between the gripper 1 and the base 2, and between the gripper 1 and the drive turntable 3.
[0086] In this embodiment, the separable clamping part 11 and limiting part 12 facilitate the installation of the gripper 1 through the first through hole 21 and the guide hole 31.
[0087] In some embodiments, such as Figure 5 and Figure 7 As shown, the clamping part 11 includes a main body 111, which is slidably connected to the first through hole 21. The main body 111 is provided with a limiting plane 111a. During the sliding of the main body 111 along the first through hole 21, the inner wall of the first through hole 21 and the limiting plane 111a are matched in a limiting engagement along the width direction of the first through hole 21 to restrict the gripper 1 from rotating relative to the first through hole 21.
[0088] Specifically, in this embodiment, the number of limiting planes 111a can be two. In other embodiments, one side of the main body 111 can be a limiting plane 111a, and the other side can be an arc surface or other irregular surface. This application does not limit the number of limiting planes 111a or the specific structure of the main body 111.
[0089] Preferably, there are two limiting planes 111a, and the two limiting planes 111a respectively limit and cooperate with the two side walls of the first through hole 21 along the width direction of the first through hole 21.
[0090] In this embodiment, the inner wall of the first through hole 21 is matched with the limiting plane 111a along the width direction of the first through hole 21, which improves the motion stability of the gripper 1 when sliding along the first through hole 21.
[0091] In some embodiments, such as Figure 7 As shown, the clamping part 11 also includes a guide part 112 fixedly connected to the main body part 111, and the guide part 112 is slidably connected to the guide hole 31. The guide part 112 is provided with a guide arc surface. During the process of driving the turntable 3 to rotate relative to the base 2, the inner wall of the guide hole 31 slides with the guide arc surface, so that the guide part 112 drives the main body part 111 to slide along the first through hole 21.
[0092] Specifically, in this embodiment, the guide portion 112 can be a cylinder with a guide arc surface. In other embodiments, the guide portion 112 can also be a cube or irregular shape with two guide arc surfaces that slide in contact with the inner wall of the guide hole 31. This application does not specifically limit the specific structure of the guide portion 112.
[0093] In this embodiment, the guide portion 112 has a guide arc surface that slides with the inner wall of the guide hole 31, which improves the motion stability of the gripper 1 when it slides along the guide hole 31.
[0094] In the above embodiments, such as Figure 5 and Figure 6 As shown, the base 2 is also provided with a limiting rib 23. At least two grippers 1 are distributed circumferentially along the limiting rib 23, and a receiving space is formed between the end of the gripping part 11 away from the limiting part 12 and the limiting rib 23.
[0095] In this embodiment, the container opening is installed in the accommodating space between the clamping part 11 and the limiting rib 23.
[0096] In this embodiment, the limiting rib 23 is used to extend into the opening of the container, which can guide and position the opening of the container. At the same time, when the water supply device tilts, the inner wall of the opening of the container will abut against the limiting rib 23, and the opening of the container will restrict the water supply device from tilting continuously, which helps to improve the installation stability of the water supply device, thereby improving the reliability of the fit between the water supply device and the container.
[0097] In some embodiments, such as Figures 5 to 7As shown, a guide slope 111b is provided at the end of the clamping part 11 away from the limiting part 12. Along the radial direction of the base 2, the guide slope 111b is located on the side surface of the clamping part 11 facing the limiting rib 23. The guide slope 111b is used to abut against the outer wall of the container opening.
[0098] In this embodiment, a guide slope 111b is provided on the side of the clamping part 11 facing the limiting rib 23, which improves the clamping stability and positioning accuracy of the gripper 1, facilitates the gripper 1 to clamp the mouth of the container, and also improves the connection reliability between the water supply device and the adapter container.
[0099] In some embodiments, such as Figure 9 As shown, the outer wall of the drive turntable 3 is provided with anti-slip protrusions 33.
[0100] In this embodiment, the anti-slip protrusions 33 uniformly arranged along the outer side wall of the drive turntable 3 provide the user with sufficient force application positions during the process of driving the drive turntable 3 to rotate along the rotating shaft 22. When the user rotates the drive turntable 3, the anti-slip protrusions 33 can increase the friction between the drive turntable 3 and the user's fingers, making it less likely for the user's fingers to slip when applying force, facilitating user operation and improving the user's experience.
[0101] In some embodiments, such as Figure 1 As shown, the water supply device also includes a drive mechanism 5. The water supply device can be a manual water supply device or an electric water supply device. When the water supply device is an electric water supply device, the drive mechanism 5 may include a water pump motor and a power supply module. This application does not limit the specific structure of the drive mechanism 5.
[0102] In the above embodiments, such as Figures 2 to 4 As shown, the water supply device also includes a cover (all figures are not shown), which is fixedly connected to the base 2 by fasteners 4. The cover protects the equipment in the drive mechanism 5.
[0103] The drive turntable 3 is located between the cover and the base 2. The drive turntable 3 is provided with a clearance through hole 34, and the fastener 4 passes through the clearance through hole 34. And as... Figure 5 and Figure 6 As shown, the base 2 also includes a third through hole 24 for mounting the fastener 4.
[0104] In this embodiment, the cover and the base 2 are fixedly connected by fasteners 4, which improves the stability of the connection between the cover and the base 2. The drive turntable 3 is provided with a clearance through hole 34 to avoid the fasteners 4, so as to prevent the fasteners 4 from affecting the rotational movement of the drive turntable 3 relative to the base 2, thereby improving the movement stability of the drive turntable 3.
[0105] The specific working process of the water supply device in this embodiment is as follows:
[0106] When gripper 1 is Figure 3 and Figure 5 The first position shown is rotated to Figure 4 and Figure 6 During the second position shown, the user applies a certain external force to the anti-slip protrusion 33 on the drive turntable 3, causing the drive turntable 3 to overcome the resistance of the protrusion 221 on the rotating shaft 22 and rotate relative to the rotating shaft 22 along the first direction X. The second surface 312 in the guide hole 31 abuts against the guide part 112 of the gripper 1 and drives the gripper 1 to move along the first direction X, thereby causing the gripper 1 to slide along the first through hole 21 in a direction away from each other until the gripper 1 reaches the second position and the rotation of the drive turntable 3 stops. During this process, the accommodating space between the clamping part 11 and the limiting rib 23 gradually increases.
[0107] When gripper 1 is Figure 4 and Figure 6 The second position shown is rotated to Figure 3 and Figure 5 During the process of reaching the first position, the user applies a certain external force to the anti-slip protrusion 33 on the drive turntable 3, causing the drive turntable 3 to overcome the resistance of the protrusion 221 on the rotating shaft 22 and rotate relative to the rotating shaft 22 along the second direction Y. The first surface 311 in the guide hole 31 abuts against the guide part 112 of the gripper 1 and drives the gripper 1 to move along the second direction Y, thereby causing the gripper 1 to slide along the first through hole 21 towards each other until the gripper 1 reaches the first position and the rotation of the drive turntable 3 stops. During this process, the accommodating space between the clamping part 11 and the limiting rib 23 gradually decreases.
[0108] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
