Description

Technical Field

[0001] This utility model relates to the field of water tank technology, and in particular to a float structure and a water dispenser. Background Technology

[0002] As people's living standards improve, consumers are paying more and more attention to drinking water health. Water dispensers are becoming increasingly popular in the market. A water dispenser consists of a water tank for temporary storage of purified water and a float assembly to protect the tank from incoming water. To ensure sufficient buoyancy, existing float designs are relatively large, making them unsuitable for use with the water tanks of water dispensers. Utility Model Content

[0003] Therefore, it is necessary to provide a float structure and a water dispenser to address the problem that the large floats in the existing technology cannot be used in the water tank installation of water dispensers.

[0004] The technical solution is as follows:

[0005] On the one hand, a float structure is provided, including:

[0006] The mounting body is provided with a water inlet channel having a water inlet end and a water outlet end. The inner side wall of the water inlet channel is provided with a valve body part, and the valve body part is provided with a water inlet hole for connecting the water inlet end and the water outlet end.

[0007] The float is flat and has a water cut-off position. The float has a connecting part that is rotatably connected to the mounting body. The connecting part is located at the end of the mounting body near the water outlet.

[0008] The movable component is movably installed at the water outlet and located between the connecting part and the valve body part;

[0009] When the float rotates upward to the water cut-off position, the connecting part lifts the movable component, causing the movable component to block the water inlet; when the float rotates downward away from the water cut-off position, the movable component falls under the action of gravity, causing the water inlet, the water inlet, and the water outlet to connect in sequence.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, the connecting portion is disposed on the end face of the float near the mounting body, and the float has an elliptical cross-section along the direction perpendicular to its own axis.

[0012] In one embodiment, the two inner sidewalls of the water inlet end are provided with clearance grooves, the two clearance grooves extend to the two outer sidewalls of the mounting body respectively, and the two clearance grooves also extend to the end face of the mounting body near the water inlet end. The connecting part passes through the water inlet end and the two clearance grooves, and is rotatably connected to the outer sidewall of the mounting body on the side away from the float.

[0013] In one embodiment, the outer side wall of the mounting body away from the float is provided with a connecting seat, and the connecting seat is rotatably connected to the end of the connecting part away from the float.

[0014] In one embodiment, the movable component includes a mounting bracket that contacts the connection portion and a seal mounted on the side of the mounting bracket near the valve body portion, the seal being configured to block the water inlet when the float rotates upward to the water cut-off position.

[0015] In one embodiment, the mounting bracket has a mounting hole on the side near the valve body, and the seal is installed in the mounting hole;

[0016] And / or, the side of the mounting bracket near the connecting portion is configured as a first arc surface;

[0017] And / or, the outer side wall of the mounting bracket is provided with at least one rib, each of the ribs extending along the axial direction of the mounting bracket and spaced apart circumferentially along the axial direction of the mounting bracket, on the side facing away from the seal, and the side of each rib away from the mounting bracket is inclined toward the axial direction of the mounting bracket.

[0018] In one embodiment, the valve body has a protrusion on the side near the mounting bracket that corresponds to the seal, and the water inlet extends to the outer surface of the protrusion.

[0019] In one embodiment, the outer surface of the protrusion is configured as a second arc surface.

[0020] In one embodiment, the outer wall of the water inlet channel is provided with a limiting part, the outer wall of the water inlet end is provided with an external thread, and the float structure also includes a connector nut, which is threadedly connected to the external thread and used to cooperate with the limiting part for clamping and installation.

[0021] On the other hand, a water dispenser is provided, including a water tank and the aforementioned float structure, wherein the water tank includes a top cover, and the float structure is fixedly installed on the top cover.

[0022] In the above embodiments, the float structure and water dispenser are used by fixing the mounting body to the mounting port of the water tank, with the float positioned inside the tank, and then connecting the inlet to an external water source. When water enters the tank through the inlet channel, the liquid level rises, and the float rotates upwards with the rising liquid level. Simultaneously, the float also drives the connecting part to rotate upwards, causing the connecting part to lift the movable component. When the float rotates upwards to the water-cut-off position, the connecting part lifts the movable component, causing the movable component to block the inlet hole and disconnect the water supply. When the liquid level in the tank drops, the float rotates downwards with the falling liquid level, and simultaneously, the float also drives the connecting part to rotate downwards. At this time, the movable component falls under the influence of gravity and separates from the inlet hole. The inlet, the inlet hole, and the outlet are then connected sequentially to allow normal water intake into the tank. In addition, the float in this application is flat, which can better install it in a narrow water tank while ensuring sufficient buoyancy, thereby protecting the water tank from water ingress and improving the practicality of the float structure and the water dispenser.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] To address the issue that larger floats cannot be used in the water tanks of water dispensers, the inventors discovered through testing and analysis that existing water tank floats in water dispensers are usually cylindrical. To ensure sufficient buoyancy, cylindrical floats are often designed to be large. Water tanks in water dispensers with compact designs are often irregularly shaped and narrow, which is not conducive to the placement of cylindrical floats with larger diameters.

[0034] Based on the above problems, the inventors designed and proposed the float ball 200 component and water dispenser according to the following embodiments of this application to solve the above technical problems.

[0035] In one embodiment, a water dispenser is provided, including a water tank and a float structure 10. The water tank includes a top cover. The float structure 10 is fixedly installed on the top cover. Thus, the float structure 10 can act as a second line of defense for the water tank, disconnecting the water supply even after the water level switch protecting the water tank fails, thereby improving the reliability and practicality of the water dispenser.

[0036] It should be noted that the water dispenser in this application includes, but is not limited to, a pipeline water dispenser.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, a float structure 10 is provided, including a mounting body 100, a float 200, and a movable component 300. The mounting body 100 has a water inlet channel 110 with an inlet end 111 and an outlet end 112. The inner wall of the water inlet channel 110 has a valve body portion 120, which has an inlet hole 121 for connecting the inlet end 111 and the outlet end 112. The float 200 is flat and has a water cut-off position. The float 200 has a connecting portion 210 rotatably connected to the mounting body 100, located at the end of the mounting body 100 near the outlet end 112. The movable component 300 is movably mounted to the outlet end 112 and located between the connecting portion 210 and the valve body portion 120. When the float 200 rotates upward to the water cut-off position, the connecting part 210 lifts the movable component 300, causing the movable component 300 to block the water inlet 121; when the float 200 rotates downward away from the water cut-off position, the movable component 300 falls under the action of gravity, causing the water inlet 111, the water inlet 121 and the water outlet 112 to be connected in sequence.

[0038] In the above embodiment, the float structure 10 is used by fixing the mounting body 100 to the mounting port of the water tank, with the float 200 positioned inside the water tank, and then connecting the water inlet 111 to an external water source. When water enters the water tank through the water inlet channel 110, the liquid level in the tank rises, and the float 200 rotates upwards as the liquid level rises. Simultaneously, the float 200 also drives the connecting part 210 to rotate upwards, causing the connecting part 210 to lift the movable component 300 upwards. When the float 200 rotates upwards to the water cut-off position, the connecting part 210 lifts the movable component 300, causing the movable component 300 to block the water inlet hole 121 to disconnect the water supply. When the liquid level in the water tank drops, the float 200 rotates downwards along with the liquid level. Simultaneously, the float 200 also drives the connecting part 210 to rotate downwards. At this time, the movable component 300 falls under the influence of gravity and separates from the water inlet 121. The water inlet end 111, the water inlet 121, and the water outlet end 112 are then connected in sequence to allow normal water intake into the water tank. Furthermore, the float 200 in this application is designed to be flat, which allows for better installation and placement in narrow water tanks while ensuring sufficient buoyancy, thereby protecting the water tank from water ingress and improving the practicality of the float structure 10.

[0039] The float 200 is flat, meaning its horizontal width is significantly smaller than its vertical height. The specific shape of the float 200 and the connecting part 210 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the float 200 and the connecting part 210 can be integrally manufactured by injection molding. The connecting part 210 can be configured as a connecting handle.

[0040] It should be noted that after the float structure 10 is installed and fixed inside the water tank, the vertical floating stroke of the float 200 is limited, and the rotation angle of the connecting part 210 is also correspondingly limited. However, the gap between the connecting part 210 and the mounting body 100 is never sufficient to allow the movable component 300 to completely detach from the water outlet 112. In other words, the size of the movable component 300 is always larger than the gap between the connecting part 210 and the mounting body 100, ensuring that the movable component 300 will not completely fall out of the water outlet 112. Specifically, in this embodiment, the rotation angle range of the connecting part 210 inside the water tank is no greater than 30°.

[0041] This application uses the application of the float structure 10 in a water dispenser as an example for its description. In other embodiments, the float structure 10 can also be applied to devices that require a water tank, such as a floor cleaning machine.

[0042] like Figure 2 and Figure 4 As shown, optionally, the connecting part 210 is disposed on the end face of the float 200 near the mounting body 100, and the float 200 has an elliptical cross-section along the direction perpendicular to its own axis. In this way, with the shorter side cross-section of the ellipse installed in a narrower cross-section in the water tank, a smaller shorter side cross-section is achieved while providing the same buoyancy, making installation and use easier.

[0043] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the two inner sidewalls of the inlet end 111 are provided with relief grooves 130. The two relief grooves 130 extend to the two outer sidewalls of the mounting body 100, respectively. The two relief grooves 130 also extend to the end face of the mounting body 100 near the inlet end 111. The connecting part 210 passes through the inlet end 111 and the two relief grooves 130, and is rotatably connected to the outer sidewall of the mounting body 100 away from the float 200. Thus, the inner sidewall of the relief groove 130 can limit and guide the connecting part 210, ensuring that the connecting part 210 can rotate stably and reliably and lift the movable component 300 to the sealing position, improving the reliability of the float structure 10. Furthermore, the connecting part 210 is partially hidden within the relief groove 130, which is beneficial for the miniaturization design of the float structure 10.

[0044] Specifically, in this embodiment, the mounting body 100 is placed vertically, the float 200 is located on one side of the mounting body 100, and the connecting part 210 is located at the bottom of the mounting body 100. The bottom of the movable component 300 is in contact with the top of the connecting part 210 located between the two clearance grooves 130.

[0045] like Figure 4 and Figure 5As shown, optionally, a connecting seat 140 is provided on the outer side wall of the mounting body 100 away from the float 200, and the connecting seat 140 is rotatably connected to the end of the connecting part 210 away from the float 200. In this way, the connecting part 210 is rotatably connected to the mounting body 100 through the connecting seat 140, which improves the convenience of assembling the float structure 10.

[0046] The connecting part 210 can be directly rotatably connected to the connecting seat 140, or it can be rotatably connected to the connecting seat 140 through intermediate elements such as pins or hinges. Specifically, in this embodiment, the mounting body 100, the valve body 120, and the connecting seat 140 are integrally formed.

[0047] Specifically, in this embodiment, the connecting part 210 includes a first section, a second section, and a third section connected in sequence. The first section passes through the water inlet end 111 and two clearance grooves 130, and is connected to the connecting seat 140. The second section is inclined. The third section is parallel to the first section and located to the side and below the first section. The third section is connected to the end face of the float 200 near the mounting body 100.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment, the movable component 300 includes a mounting bracket 310 that contacts the connecting portion 210, and a seal 320 mounted on the side of the mounting bracket 310 near the valve body portion 120. The seal 320 is configured to block the water inlet 121 when the float 200 rotates upward to the water-off position. Thus, when the float 200 rotates upward to the water-off position, the connecting portion 210 lifts the mounting bracket 310, causing the seal 320 at the top of the mounting bracket 310 to block the water inlet 121 and disconnect the water supply. When the liquid level in the water tank drops, the float 200 rotates downwards along with the liquid level. At the same time, the float 200 also drives the connecting part 210 to rotate downwards. At this time, the mounting bracket 310 and the seal 320 fall down under the action of gravity. The seal 320 separates from the water inlet 121, and the water inlet 111, the water inlet 121 and the water outlet 112 are connected in sequence so that water can be normally fed into the water tank.

[0049] like Figure 3 and Figure 4 As shown, optionally, the mounting bracket 310 has a mounting hole 311 on the side near the valve body 120, and the seal 320 is installed in the mounting hole 311. In this way, the mounting hole 311 can play a positioning role, ensuring that the seal 320 can be quickly and accurately installed in the position corresponding to the water inlet 121 on the mounting bracket 310, thereby improving the convenience of assembling the float structure 10.

[0050] The seal 320 can be a silicone plug, a rubber plug, or other structure capable of sealing the installation port. In other embodiments, the seal 320 can also be directly fixed to the side of the mounting bracket 310 near the valve body by snap-fit, plug-in, adhesive, or other means.

[0051] like Figure 3 As shown, optionally, the side of the mounting bracket 310 near the connecting part 210 is configured as a first arc surface 313. In this way, during the upward rotation of the connecting part 210, the connecting part 210 always maintains contact with the first arc surface 313, ensuring that the connecting part 210 can smoothly and steadily lift the mounting bracket 310, thereby improving the reliability of the float structure 10.

[0052] Specifically, in this embodiment, the bottom wall of the mounting hole 311 is provided with a through hole 312, which extends to the first arc surface 313. Thus, the through hole 312 can reduce the weight of the mounting bracket 310, lower the threshold for the connecting part 210 to lift the mounting bracket 310, ensure that the connecting part 210 can smoothly and steadily lift the mounting bracket 310, and improve the reliability of the float structure 10.

[0053] like Figure 2 and Figure 3 As shown, optionally, the outer wall of the mounting bracket 310 is provided with at least one rib 314, each rib 314 extending along the axial direction of the mounting bracket 310 and spaced apart circumferentially along the mounting bracket 310. Along the axial direction of the mounting bracket 310 and on the side facing away from the seal 320, the side of each rib 314 away from the mounting bracket 310 is inclined towards the axial direction of the mounting bracket 310. Thus, the outer diameter of the end of the mounting bracket 310 near the valve body 120 is larger, and it can be radially limited to the inner wall of the inlet end 111, ensuring the stability of the mounting bracket 310 within the inlet end 111. Conversely, the outer diameter of the end of the mounting bracket 310 near the connecting part 210 is smaller, and there is a certain distance between it and the inner wall of the inlet end 111, preventing interference between the mounting bracket 310 and the inner wall of the inlet end 111 when it is lifted by the connecting part 210, thereby improving the reliability of the float structure 10.

[0054] like Figure 3 and Figure 5 As shown, in one embodiment, the valve body 120 has a protrusion 122 on the side near the mounting bracket 310 that corresponds to the seal 320, and the water inlet 121 extends to the outer surface of the protrusion 122. Thus, the protrusion 122 prevents interference between the mounting bracket 310 and the valve body 120, improving the reliability of the float structure 10.

[0055] like Figure 3 and Figure 5As shown, optionally, the outer surface of the protrusion 122 is configured as a second arc surface 123. In this way, the second arc surface 123 can increase the contact area between the protrusion 122 and the seal 320, thereby enhancing the sealing performance between the seal 320 and the protrusion 122 and improving the reliability of the float structure 10.

[0056] Specifically, in this embodiment, the water inlet 121 includes a first end communicating with the water inlet 111 and a second end communicating with the water outlet 112. Along the flow direction of water within the water inlet 121, the inner diameter of the first end gradually decreases, and the inner diameter of the side of the first end closest to the second end is the same as the inner diameter of the second end. The inner diameter of the second end remains unchanged. Thus, the water inlet 121 can act as a flow obstructor, smoothly guiding water from the water inlet 111 to the water outlet 112 while simultaneously preventing water from flowing from the water outlet 112 back to the water inlet 111, thereby improving the practicality of the float 200 assembly.

[0057] like Figure 1 and Figure 3 As shown, in one embodiment, the outer wall of the water inlet channel 110 is provided with a limiting portion 150. The outer wall of the water inlet end 111 is provided with an external thread 160. The float structure 10 also includes a connector nut 400, which is threadedly connected to the external thread 160 and is used to cooperate with the limiting portion 150 for clamping and installation.

[0058] In this specific embodiment, the top cover is provided with an installation port. The water inlet 111 passes through the installation port from the inside of the top cover, and after the limiting part 150 abuts against the inner wall of the top cover, the connector nut 400 is threadedly connected to the external thread 160, so that the limiting part 150 can cooperate with the connector nut 400 to clamp the top cover, so as to fix the mounting body 100 on the top cover.

[0059] The limiting part 150 can be configured as a limiting flange, a limiting block or other limiting structure.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
