Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, and in particular to drinking water devices. Background Technology

[0002] Currently, most tabletop water dispensers on the market have a vertical, upward-lifting water tank layout, with a small number having a horizontally placed water tank. With the horizontally placed water tank, water droplets may fall onto the table when the water tank is picked up. Utility Model Content

[0003] Therefore, it is necessary to provide a drinking water device to address the problem of water droplets falling onto the table when the water tank is picked up.

[0004] A drinking water device, comprising:

[0005] A water tank base, wherein the water tank base is provided with a insertion cavity and an insertion interface, the insertion cavity being located on the outer periphery of the insertion interface;

[0006] A water tank, which is plugged into the connector, wherein the connector cavity is used to accommodate at least a portion of the residual water between the water tank and the water tank base; and

[0007] A negative pressure element, connected to the insertion cavity, is configured to extract and store the residual water.

[0008] Negative pressure components help prevent residual water droplets from falling onto the desktop, improving the user experience. Furthermore, their simple structure requires no external power, saving energy.

[0009] In one embodiment, the water tank base is provided with a negative pressure channel, one end of which is connected to the insertion cavity;

[0010] The negative pressure element is connected to the other end of the negative pressure channel, and the negative pressure element is configured to extract and store the residual water.

[0011] The negative pressure component is connected to the negative pressure channel and the insertion cavity. The negative pressure component generates negative pressure when the water tank is disassembled, and after the water tank is disassembled, it forms the power to extract residual water, thereby extracting residual water and preventing residual water from dripping onto the table.

[0012] In one embodiment, the negative pressure element is an elastic element with a negative pressure cavity that is connected to the negative pressure channel and is used to store the residual water.

[0013] This elastic element has a simple structure and small size. Compared with the water tank with a water box to hold residual water in related technologies, this drinking device does not need to occupy the volume of the water tank, which helps to increase the water tank's capacity, reduce the frequency of water filling by users, and improve the user experience.

[0014] In one embodiment, the water tank seat includes a sealing ring, and the water tank and the water tank seat are sealed together by the sealing ring;

[0015] The elastic element has a first state and a second state. When the elastic element switches from the first state to the second state, the elastic element can extract and store the residual water.

[0016] When the elastic element is in the first state, the water tank and the water tank seat are partially separated, and the water tank and the water tank seat are kept in a sealed connection by the sealing ring, and the negative pressure cavity contracts;

[0017] When the elastic element is in the second state, the water tank is completely separated from the water tank seat; the negative pressure cavity is reset.

[0018] Because the water tank and its base are connected by a sealing ring, they remain sealed until the tank is completely separated. At the moment of disassembly, the tank and base are not completely separated, but the sealing ring maintains a tight connection, creating negative pressure in the negative pressure channel. This causes the elastic element to contract under atmospheric pressure. When the tank is completely separated, the insertion cavity connects to the outside atmosphere, and gas flows through the negative pressure channel towards the elastic element. The negative pressure cavity returns to its original state from its contracted state, generating suction. Residual water in the insertion cavity is drawn into the negative pressure cavity, causing the elastic element to draw in air and reset, while storing the remaining water.

[0019] In one embodiment, the negative pressure cavity is spherical, cubic, or conical, and can be used to store residual water to meet the needs of different application scenarios.

[0020] And / or, the elastic element is detachably connected to the end of the negative pressure channel away from the insertion cavity, so that when there is a lot of residual water stored in the elastic element, the user can remove the elastic element and pour out the residual water.

[0021] In one embodiment, the elastic element is sleeved on the end of the negative pressure channel away from the insertion cavity; when it is necessary to disassemble the elastic element, the user can directly remove it. During assembly, the elastic element is simply sleeved on the end of the negative pressure channel away from the insertion cavity using its elasticity. This negative pressure element has a simple structure, which helps to reduce costs.

[0022] Alternatively, the negative pressure component may be inserted into the negative pressure channel at the end furthest from the insertion cavity to facilitate the assembly and disassembly of the elastic component;

[0023] Alternatively, the negative pressure component may also include a quick-connect fitting connected to the elastic element, wherein the quick-connect fitting is inserted into the end of the negative pressure channel furthest from the insertion cavity. This quick-connect fitting improves the stability of the connection between the elastic element and the end of the negative pressure channel furthest from the insertion cavity, and enables rapid assembly and disassembly. When the user needs to pour out residual water, the quick-connect fitting structure improves the user's operating efficiency and enhances the user experience.

[0024] In one embodiment, the negative pressure channel includes:

[0025] The first sub-channel is connected at one end to the insertion cavity;

[0026] The second sub-channel has one end connected to the end of the first sub-channel away from the insertion cavity, and the other end connected to the negative pressure component.

[0027] The negative pressure channel connects the insertion cavity and the negative pressure component through the first sub-channel and the second sub-channel, which helps to increase the flexibility of the negative pressure component's placement.

[0028] In one embodiment, the water tank base includes:

[0029] case;

[0030] The second check valve assembly is disposed on the housing, the insertion cavity and the insertion interface are disposed on the side of the second check valve assembly facing the water tank, and the negative pressure channel is disposed on the second check valve assembly.

[0031] This drinking water device improves safety by placing the insertion cavity and insertion interface on the second check valve assembly that directly cooperates with the water tank, which facilitates timely recovery of residual water generated during the disassembly of the water tank.

[0032] In one embodiment, the axis of the second check valve assembly extends horizontally, and the water tank is assembled or disassembled horizontally on the water tank seat.

[0033] This drinking water device adapts the negative pressure component to the working conditions of horizontally arranged water tanks that generate a lot of residual water. This allows residual water to be directly extracted and stored during the disassembly of the water tank, eliminating the need for a water box that takes up space on the water tank. This increases the effective volume of the water tank, reduces the frequency of water filling for users, and improves the user experience.

[0034] In one embodiment, the second check valve assembly includes:

[0035] A valve seat is disposed on the housing. The valve seat includes a connecting pipe and a sleeve. The sleeve is sleeved around the outer periphery of the connecting pipe and spaced apart from the connecting pipe, so that a insertion cavity is formed between the sleeve and the connecting pipe. The end of the connecting pipe facing the water tank is the insertion interface. The negative pressure channel is disposed on the valve seat, and the negative pressure component is connected to the valve seat.

[0036] The first valve core is inserted into the valve seat.

[0037] Since the residual water during the disassembly of the water tank is mainly generated in the insertion cavity of the second check valve assembly, the drinking water device uses the gap between the connecting pipe and the sleeve of the second check valve assembly to form the insertion cavity. The negative pressure component is directly connected to the insertion cavity so that the negative pressure component can directly extract the residual water. Attached Figure Description

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.

[0050] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0055] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of the assembly structure of a drinking water device provided in one embodiment of this application is shown. Figure 2 A schematic diagram of the water tank assembly state provided in one embodiment of this application is shown.

[0056] like Figure 1 and Figure 2 As shown, this embodiment provides a drinking water device, which includes a water tank base 100 and a water tank 200. The water tank base 100 is provided with a connector 120, and the water tank 200 is inserted into the connector 120. When the water tank 200 is assembled on the water tank base 100, the water tank 200 is inserted into the connector 120. When the water tank 200 is removed from the water tank base 100, the water tank 200 is separated from the connector 120.

[0057] In addition, the water tank base 100 is provided with a plug-in cavity 110, which is located on the outer periphery of the plug-in interface 120. When the water tank 200 is plugged into the water tank base 100, a portion of the water tank 200 is located in the plug-in cavity 110.

[0058] Specifically, the water tank base 100 includes a front panel, a plug-in cavity 110 and a plug-in interface 120 disposed on the front panel.

[0059] The water dispenser also includes a negative pressure component 300, which is connected to the insertion cavity 110. The negative pressure component 300 can extract and store residual water, thereby preventing residual water from dripping onto the table and improving the user experience. At the same time, the negative pressure component 300 has a simple structure, requires no external power, and saves energy.

[0060] The water tank base 100 includes a housing 150 and a second check valve assembly 160. The second check valve assembly 160 is mounted on the housing 150, with a insertion cavity 110 and an insertion interface 120 located on the side of the second check valve assembly 160 facing the water tank 200 for easy insertion and engagement with the water tank 200. By locating the insertion cavity 110 and the insertion interface 120 on the second check valve assembly 160, which directly engages with the water tank 200, this drinking water device facilitates timely recovery of residual water generated during the disassembly of the water tank 200, thus improving safety.

[0061] The water tank base 100 also has an outlet 140 and a second check valve assembly 160 for connecting or disconnecting the water passage between the outlet 140 and the connector 120.

[0062] At work, such as Figure 2 and Figure 3 As shown, when the water tank 200 is assembled on the water tank base 100, the outlet 140 and the connector 120 are connected, thereby connecting the outlet 140 to the inside of the water tank 200, so that water in the water tank 200 can be supplied to the water tank base 100 through the connector 120. Figure 4 As shown, Figure 4 This diagram illustrates the structure of a water tank 200 separated from its base 100 according to one embodiment of this application. When the water tank 200 is separated from the base 100, the second check valve assembly 160 cuts off the water flow between the outlet 140 and the connector 120.

[0063] like Figures 5 to 7 As shown, in one embodiment, the water tank base 100 is provided with a negative pressure channel 130, one end of which is connected to the insertion cavity 110; a negative pressure component 300 is connected to the other end of the negative pressure channel 130, and the negative pressure component 300 is used to extract and store residual water. The negative pressure component 300, through its connection with the negative pressure channel 130 and the insertion cavity 110, automatically generates negative pressure the moment the water tank 200 is disassembled, and provides the force to extract residual water after disassembly, thus preventing residual water from dripping onto the table. Specifically, the negative pressure channel 130 is located on the second check valve assembly 160.

[0064] Because the residual water is mainly concentrated below the insertion cavity 110 due to gravity, the negative pressure component 300 is set below the insertion cavity 110 to improve the effect of the negative pressure component 300 in extracting the residual water.

[0065] Optionally, the negative pressure component 300 is an elastic component with a negative pressure cavity 310 connected to the negative pressure channel 130. The negative pressure cavity 310 is used to store residual water. This elastic component has a simple structure and small size. Compared to the water tank with a water box to hold residual water in related technologies, this drinking device does not require the volume of the water tank 200, which helps to increase the water capacity of the water tank 200, reduce the frequency of water filling by users, and improve the user experience.

[0066] The water tank base 100 also includes a sealing ring 170. When the water tank 200 is inserted into the insertion cavity 110, more specifically, the first check valve assembly 220 of the water tank 200 is inserted into the second check valve assembly 160, and the sealing ring 170 seals the second check valve assembly 160, thereby preventing water leakage and improving the user experience.

[0067] Furthermore, the elastic element has a first state and a second state. When the elastic element switches from the first state to the second state, it can extract and store residual water. Specifically, the reason for the elastic element forming the first state is that the water tank 200 and the water tank seat 100 are not completely separated, but the water tank 200 and the water tank seat 100 are still sealed together by the sealing ring 170. Since the water tank 200 and the water tank seat 100 are separated, a negative pressure is generated in the negative pressure channel 130, causing the negative pressure cavity 310 to contract. The reason for the elastic element forming the second state is that the water tank 200 and the water tank seat 100 are completely separated, the insertion cavity 110 is connected to the outside atmosphere, and the gas flows towards the elastic element through the negative pressure channel 130. The negative pressure cavity 310 returns from the contracted state to the original state, that is, from the first state to the second state. This change trend causes the negative pressure cavity 310 to generate suction, and the residual water in the insertion cavity 110 is extracted into the negative pressure cavity 310. The elastic element draws in air and resets, and stores the residual water.

[0068] More specifically, the original state of the negative pressure chamber 310 is the free state of the negative pressure chamber 310, in which the negative pressure chamber 310 neither expands nor contracts, or the negative pressure chamber 310 expands slightly under the action of residual water or air.

[0069] Optionally, the negative pressure chamber 310 can be spherical, cubic, or conical, as long as it can store residual water to meet the needs of different application scenarios. Preferably, the negative pressure chamber 310 is spherical, as the spherical structure is easy to mold and has an aesthetic appeal.

[0070] In one embodiment, the elastic element is detachably connected to the end of the negative pressure channel 130 away from the insertion cavity 110, so that when there is a lot of residual water stored in the elastic element, the user can remove the elastic element and pour out the residual water.

[0071] In one embodiment, the elastic element is sleeved on the end of the negative pressure channel 130 away from the insertion cavity 110. When it is necessary to disassemble the elastic element, the user can directly remove it. During assembly, the elastic element is simply sleeved on the end of the negative pressure channel 130 away from the insertion cavity 110 using its elasticity. This negative pressure element 300 has a simple structure, which helps to reduce costs.

[0072] In one embodiment, the negative pressure member 300 is inserted into the negative pressure channel 130 at the end away from the insertion cavity 110 to facilitate the assembly and disassembly of the elastic member.

[0073] In one embodiment, the negative pressure component 300 further includes a quick-connect connector connected to the negative pressure component 300, which is inserted into the end of the negative pressure channel 130 away from the insertion cavity 110. This quick-connect connector helps improve the stability of the connection between the elastic component and the end of the negative pressure channel 130 away from the insertion cavity 110, and enables quick assembly and disassembly. When the user needs to pour out residual water, the quick-connect connector structure helps improve the user's operating efficiency and enhances the user experience.

[0074] like Figure 6 As shown, the negative pressure channel 130 includes a first sub-channel 131 and a second sub-channel 132. One end of the first sub-channel 131 is connected to the insertion cavity 110; one end of the second sub-channel 132 is connected to the end of the first sub-channel 131 away from the insertion cavity 110, and the other end is connected to the negative pressure component 300. This negative pressure channel 130 connects the insertion cavity 110 and the negative pressure component 300 through the first sub-channel 131 and the second sub-channel 132, which helps to increase the flexibility of the negative pressure component 300's placement.

[0075] Specifically, the first sub-channel 131 is arranged horizontally, and the second sub-channel 132 is perpendicular to the first sub-channel 131, so that the residual water can flow more easily into the negative pressure cavity 310 by utilizing the gravity of the residual water.

[0076] Furthermore, the axis of the second check valve assembly 160 extends horizontally, and the water tank 200 is assembled or disassembled horizontally on the water tank base 100. This drinking device adapts the negative pressure component 300 to the working condition of a horizontally positioned water tank 200 where a relatively large amount of residual water is generated. This allows for direct extraction and storage of residual water during the disassembly of the water tank 200, eliminating the need for a bulky water box on the water tank 200. This increases the effective volume of the water tank 200, reduces the frequency of water refills, and improves the user experience.

[0077] The second check valve assembly 160 includes a valve seat 161 and a first valve core 162. The valve seat 161 is disposed on the housing 150. The valve seat 161 includes a connecting pipe 1611 and a sleeve 1612. The sleeve 1612 is sleeved on the outer periphery of the connecting pipe 1611 and spaced apart from the connecting pipe 1611, so that a insertion cavity 110 is formed between the sleeve 1612 and the connecting pipe 1611. The end of the connecting pipe 1611 facing the water tank 200 is a insertion interface 120. A negative pressure channel 130 is disposed on the valve seat 161, and a negative pressure component 300 is connected to the valve seat 161. The first valve core 162 is inserted into the valve seat 161. Since the residual water during the disassembly of the water tank 200 is mainly generated in the insertion cavity 110 of the second check valve assembly 160, the drinking water device uses the gap between the connecting pipe 1611 and the sleeve 1612 of the second check valve assembly 160 to form the insertion cavity 110. The negative pressure component 300 is directly connected to the insertion cavity 110 so that the negative pressure component 300 can directly extract the residual water.

[0078] Specifically, one end of the first sub-channel 131 of the negative pressure channel 130 is connected to the insertion cavity 110, which is arranged horizontally. The first sub-channel 131 can extend horizontally or be slightly inclined downwards. One end of the second sub-channel 132 is connected to the other end of the first sub-channel 131, and the other end of the second sub-channel 132 is connected to the outside of the valve seat 161. The negative pressure component 300 is connected to the second sub-channel 132. For example, the first sub-channel 131 is arranged horizontally, and the second sub-channel 132 is perpendicular to and connected to the first sub-channel 131.

[0079] like Figure 4 and Figure 5 As shown, the water tank 200 includes a tank body 210 and a first check valve assembly 220. The first check valve assembly 220 extends axially in the horizontal direction and is disposed in the tank body 210. When the water tank 200 is assembled on the water tank seat 100, the first check valve assembly 220 abuts against the second check valve assembly 160, realizing communication between the inside of the tank body 210 and the outlet 140.

[0080] Furthermore, the first check valve assembly 220 includes a connector 221, which is a portion of the valve seat of the first check valve assembly 220. Simultaneously, the second valve core 223 of the first check valve assembly 220 passes through the connector 221. The interior of the connector 221 and the second valve core 223 together define a receiving cavity 222. When the water tank 200 is assembled on the water tank seat 100, the connector 221 is inserted into the insertion cavity 110 and seals with the sealing ring 170, while the connecting pipe 1611 is inserted into the receiving cavity 222.

[0081] like Figures 5 to 7As shown, because the insertion tube 221 and the sleeve 160 are sealed together by the sealing ring 170, the receiving cavity 222 and the insertion cavity 110 are in a sealed state. Figure 6 As shown, Figure 6 This diagram illustrates the airflow direction during the contraction process of the negative pressure component 300 provided in one embodiment of this application. At the moment the water tank 200 is disassembled, the water tank 100 and the water tank seat 200 are not completely separated, but the water tank 100 and the water tank seat 200 remain sealed together by the sealing ring 170. At this time, since the accommodating cavity 222 and the insertion cavity 110 remain sealed under the seal of the sealing ring 170, but the insertion tube 221 is pulled out of the insertion cavity 110, negative pressure is generated in the insertion cavity 110 and the accommodating cavity 222. This negative pressure acts on the elastic component through the negative pressure channel 130, causing the elastic component to be in a first state, and the negative pressure cavity 310 on the elastic component contracts. For example... Figure 7 As shown, Figure 7 This diagram illustrates the airflow direction during the process of the negative pressure component 300 restoring to its original state according to an embodiment of this application. When the water tank 200 is completely separated from the water tank base 100, the accommodating cavity 222 is connected to the external atmosphere, and the gas flows towards the elastic component through the negative pressure channel 130, restoring the negative pressure cavity 310 from its contracted state to its original state. Since the elastic component is under negative pressure when it contracts, this negative pressure generates suction when external gas enters through the negative pressure channel 130, drawing residual water from the accommodating cavity 222 and the insertion cavity 110 into the negative pressure cavity 310, causing the elastic component to be in its second state, and the negative pressure cavity 310 on the elastic component to return to its original state.

[0082] like Figure 6 and Figure 7 As shown, when the water tank 200 is disassembled, residual water remains in the receiving cavity 222 and the insertion cavity 110. Since the receiving cavity 222 is located on the water tank 200, the residual water in the receiving cavity 222 can easily drip onto the table after the water tank 200 is removed from the water tank seat 100. To avoid this situation, the inner wall of the insertion tube 221 is at least partially fitted with the outer wall of the connecting tube 150 with a gap, so that some of the residual water in the receiving cavity 222 can flow into the insertion cavity 110 through the gap and be drawn into the elastic element under the negative pressure of the elastic element.

[0083] like Figure 7 As shown, along the axial direction of the insertion pipe 221, the inner wall of the end of the insertion pipe 221 away from the housing 210 is provided with a gradually increasing diameter inclined surface 2211, thereby further increasing the distance from the inner wall of the insertion pipe 221 away from the housing 210 to the connecting pipe 150. This helps to increase the gap, which can both guide the flow, making it easier for residual water in the accommodating cavity 222 to flow into the insertion cavity 110, and guide the insertion of the connecting pipe 150 into the insertion pipe 221 during the assembly of the water tank 200, thus preventing jamming.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
