[0015] As a preferred solution of the drinking water device provided by the present utility model, the water inlet assembly includes:
[0016] A first water inlet pipeline, whose inlet is communicated with the water source;
[0017] A second water inlet pipeline, whose outlet is communicated with the inlet of the heating device;
[0018] A Venturi valve, which is arranged between the first water inlet pipeline and the second water inlet pipeline and is connected to both of them, and the contraction section, the throat section and the diffusion section are all formed on the Venturi valve.
[0019] As a preferred solution of the drinking water device provided by the present utility model, the heating device includes:
[0020] A water storage tank body for containing water;
[0021] A heating structure, which is arranged on the water storage tank body and is used for heating the water in the water storage tank body.
[0022] As a preferred solution of the drinking water device provided by the present utility model, the hot water tank further includes a liquid level detection member, which is arranged in the water storage tank body for detecting the liquid level of the water in the water storage tank body, and the liquid level detection member is in communication connection with the heating structure.
[0023] As a preferred solution of the drinking water device provided by the present utility model, a water inlet valve is arranged between the water inlet assembly and the water source; the drinking water device further includes a drainage assembly, the drainage assembly is in communication connection with the water inlet valve and can empty the water in the hot water tank.

[0025] The beneficial effects of the present utility model are:
[0026] The drinking water device provided by the present utility model connects the outlet of the heating device to the water outlet nozzle, allowing users to obtain hot water at the water outlet nozzle. By setting up an exhaust pipeline, when the water inlet assembly stops supplying water, the exhaust pipeline can form a communicating vessel with the heating device, and the water in the water outlet pipeline can flow back to the exhaust pipeline through the water inlet assembly, maintaining the same air pressure in the exhaust pipeline and the water inlet assembly, thereby preventing the residual water in the water outlet pipeline from dripping from the water outlet nozzle. This design can omit the setting of the water outlet valve and reduce the processing cost to a certain extent. By forming a gradually connected contraction section, throat section, and diffusion section in at least part of the water inlet assembly, when water is supplied from the water source to the heating device, the water flow velocity increases and the pressure decreases when passing through the contraction section, and the pressure of the water flow reaches the minimum at the throat section, so that the water in the water source can only flow into the heating device and cannot flow into the exhaust pipeline, thus realizing the control of the water flow direction. In addition, the drinking water device omits the setting of a water storage tank, which can avoid the situation of bacterial growth caused by the water in the water storage tank not being updated for a long time, thereby ensuring the water use safety of users.
[0027] When the drinking water device is in use, it usually includes the following scenarios: 1) When it is used for the first time, the water source supplies water to the heating device through the water inlet assembly. When the water flow passes through the contraction section, the flow velocity increases and the pressure decreases, and the pressure of the water flow reaches the minimum at the throat section, so that the water in the water source can only flow into the heating device and cannot flow into the exhaust pipeline, thus preventing the heating device from starting to dry burn and affecting the service life of the heating device; 2) When the water inlet assembly stops supplying water, the exhaust pipeline can form a communicating vessel with the heating device, and the water in the water outlet pipeline can flow back to the exhaust pipeline through the water inlet assembly, maintaining the same air pressure in the exhaust pipeline and the water inlet assembly, thereby preventing the residual water in the water outlet pipeline from dripping from the water outlet nozzle; 3) When the water inlet assembly starts to supply water to the heating device again, when the water flow passes through the contraction section, the flow velocity increases and the pressure decreases, and the pressure of the water flow reaches the minimum at the throat section. At this time, the water in the exhaust pipeline can flow to the heating device together with the water in the water inlet assembly, thereby realizing the emptying of the exhaust pipeline to prepare for receiving the water in the water outlet pipeline again when the water inlet assembly stops supplying water. In addition, although a small amount of bacteria will be generated due to the water in the exhaust pipeline being connected to the outside, after the water inlet assembly is restarted, the water in the exhaust pipeline will flow back to the heating device for heating again, which can play a bactericidal effect and further ensure the water use safety of users.

[0041] Figure 1 The structural schematic diagram of the drinking water device provided in this embodiment is shown. As Figure 1 shown, this embodiment provides a drinking water device, which includes a heating device 100, a water outlet assembly 200, a water inlet assembly 300, and an exhaust pipe 410. The heating device 100 is configured to heat the water passing through it; the water outlet assembly 200 includes a water outlet nozzle 210 and a water outlet pipe 220. The water outlet pipe 220 communicates with the outlet of the heating device 100 and the water outlet nozzle 210, and the water outlet nozzle 210 is always in communication with the outside; the water inlet assembly 300 communicates the water source and the inlet of the heating device 100. The water inlet assembly 300 includes a contraction section 321, a throat section 322, and a diffuser section 323 that are connected in sequence along the water inlet direction. The inner diameter of the contraction section 321 decreases in sequence along the water inlet direction, and the inner diameter of the diffuser section 323 increases in sequence along the water flow direction; one end of the exhaust pipe 410 is connected to the throat section 322, and the other end of the exhaust pipe 410 is in communication with the outside. The exhaust pipe 410 can form a communicating vessel with the heating device 100 when the water inlet assembly 300 stops admitting water.
[0042] The drinking water device provided in this embodiment connects the outlet of the heating device 100 to the water outlet 210, enabling users to obtain hot water at the water outlet 210. By setting up the exhaust pipe 410, when the water inlet assembly 300 stops supplying water, the exhaust pipe 410 can form a communicating vessel with the heating device 100, and the water in the water outlet pipe 220 can flow back to the exhaust pipe 410 through the water inlet assembly 300, maintaining the same air pressure in the exhaust pipe 410 and the water inlet assembly 300, thereby preventing the water remaining in the water outlet pipe 220 from dripping from the water outlet 210. This design can omit the setting of the water outlet valve and reduce the processing cost to a certain extent. By forming a gradually connected contraction section 321, throat section 322, and diffusion section 323 in at least part of the water inlet assembly 300, when the water source supplies water to the heating device 100, when the water flows through the contraction section 321, the flow rate becomes faster and the pressure becomes smaller. The pressure of the water in the throat section 322 reaches the minimum, causing the water in the water source to only flow towards the heating device 100 and not towards the exhaust pipe 410, thus achieving the control of the water flow direction. In addition, this drinking water device omits the setting of the water storage tank, which can avoid the situation of bacteria breeding caused by the long-term non-renewal of the water in the water storage tank, thereby ensuring the water safety of users.
[0043] It should be noted that in this embodiment, the water source refers to the direct drinking water in the building's pipeline or the water purification host, and the water supplied to the heating device 100 is purified water after filtration. The drinking water device provided in this embodiment can be a pipeline machine, a water dispenser, or other drinking water devices with a heating function.
[0044] When the drinking water device is in use, it usually includes the following scenarios: 1) When it is used for the first time, the water source supplies water to the heating device 100 through the water inlet assembly 300. When the water flows through the contraction section 321, the flow rate becomes faster and the pressure becomes smaller. The pressure of the water at the throat section 322 reaches the minimum, so that the water in the water source can only flow to the heating device 100 and cannot flow into the exhaust pipe 410, thus preventing the heating device 100 from starting to dry burn and affecting the service life of the heating device 100; 2) When the water inlet assembly 300 stops supplying water, the exhaust pipe 410 can form a communicating vessel with the heating device 100, and the water in the water outlet pipe 220 can flow back to the exhaust pipe 410 through the water inlet assembly 300, keeping the same air pressure in the exhaust pipe 410 and the water inlet assembly 300, so as to prevent the water remaining in the water outlet pipe 220 from dripping from the water outlet nozzle 210; 3) When the water inlet assembly 300 starts to supply water to the heating device 100 again, when the water flows through the contraction section 321, the flow rate becomes faster and the pressure becomes smaller. The pressure of the water at the throat section 322 reaches the minimum. At this time, the water in the exhaust pipe 410 can flow to the heating device 100 together with the water in the water inlet assembly 300, so as to empty the exhaust pipe 410 in preparation for receiving the water in the water outlet pipe 220 again when the water inlet assembly 300 stops supplying water. In addition, although the water in the exhaust pipe 410 will be in communication with the outside and cause a small amount of bacteria to be generated, after the water inlet assembly 300 is restarted, the water in the exhaust pipe 410 will flow back to the heating device 100 for heating again, which can play a bactericidal effect and further ensure the water use safety of users.
[0045] In this embodiment, one end of the exhaust pipe 410 far from the water inlet assembly 300 is communicated with the water outlet nozzle 210 to realize the communication between the exhaust pipe 410 and the outside through the water outlet nozzle 210. The structure is simple and convenient for assembly.
[0046] As Figure 1 shown, the heating device 100 is a hot water tank, and the highest point of the exhaust pipe 410 is higher than the hot water tank. By setting the heating device 100 as a hot water tank, the water storage capacity of the heating device 100 can be increased, so that the water in the water outlet pipe 220 can all flow back to the hot water tank when the water inlet assembly 300 stops supplying water; setting the highest point of the exhaust pipe 410 higher than the hot water tank can prevent the water in the exhaust pipe 410 from flowing out of the water outlet nozzle 210 when the water level in the hot water tank is too high.
[0047] Specifically, the hot water tank includes a water storage tank body 110 and a heating structure. The water storage tank body 110 is used for holding water; the heating structure is arranged on the water storage tank body 110 and is used for heating the water in the water storage tank body 110. The heating structure of the hot water tank in this embodiment is not described in detail, and any heating structure in the prior art that can realize heating the water in the water storage tank body 110 is within the protection scope of this embodiment.
[0048] In the related art, when the drinking water device is powered on for the first time, since there is no water in the water storage tank body 110, it is very easy to cause dry burning of the water storage tank body 110, affecting the service life of the drinking water device. To solve this problem, in this embodiment, the hot water tank further includes a liquid level detection member 120, which is arranged in the water storage tank body 110 for detecting the liquid level of the water in the water storage tank body 110, and the liquid level detection member 120 is communicatively connected to the heating structure. When the liquid level detection member 120 detects that the water in the water storage tank body 110 reaches the preset liquid level, the control module of the drinking water device controls the heating structure to heat the water in the water storage tank body 110 to avoid the situation of dry burning of the water storage tank body 110, thereby being able to extend the service life of the drinking water device. This embodiment does not limit the specific structure of the liquid level detection member 120, which can be a liquid level sensor, a float liquid level detection device or other detection devices that can detect the liquid level of the water in the water storage tank body 110 in the prior art.
[0049] It should be noted that in other embodiments, the heating device 100 can also be an instant heating device, which can also achieve the above effects. The instant heating device is a relatively mature technology in the prior art, and the specific structure of the instant heating device will not be described in detail in this embodiment.
[0050] Continue as Figure 1 As shown, a buffer box body 420 is arranged on the exhaust pipe 410. Specifically, the exhaust pipe 410 includes a first pipe 411 and a second pipe 412, the buffer box body 420 is arranged between the first pipe 411 and the second pipe 412, both ends of the first pipe 411 are respectively communicated with the throat section 322 and the inlet of the buffer box body 420, and both ends of the second pipe 412 are respectively communicated with the outlet of the buffer box body 420 and the water outlet 210. When the water inlet assembly 300 stops water inlet, the residual water in the water outlet pipe 220 can flow back into the hot water tank. Since a communicating vessel is formed between the exhaust pipe 410 and the hot water tank, the water in the hot water tank can flow into the buffer box body 420 through the first pipe 411, and the excess gas in the buffer box body 420 can be discharged from the second pipe 412 to avoid the situation that the residual water in the water outlet pipe 220 is too much and drips from the water outlet 210. By arranging the buffer box body 420, the water holding volume of the exhaust pipe 410 can be increased to ensure that all the residual water in the water outlet pipe 220 flows back into the hot water tank.
[0051] Optionally, the height of the inner cavity top surface of the buffer box body 420 is higher than the highest liquid level of the hot water tank to avoid the situation that when the water level in the hot water tank is relatively high, the water in the buffer box body 420 overflows into the second pipe 412, and then the water in the second pipe 412 drips from the water outlet 210.
[0052] Optionally, the height of the inner cavity bottom surface of the buffer box body 420 is lower than the highest liquid level of the hot water tank, so as to prevent the water in the hot water tank from failing to flow into the buffer box body 420, thereby ensuring that the residual water in the water outlet pipeline 220 cannot all flow back into the hot water tank.
[0053] The water inlet assembly 300 includes a first water inlet pipeline 310, a Venturi valve 320 and a second water inlet pipeline 330. The inlet of the first water inlet pipeline 310 is communicated with a water source; the outlet of the second water inlet pipeline 330 is communicated with the inlet of the hot water tank; the Venturi valve 320 is arranged between the first water inlet pipeline 310 and the second water inlet pipeline 330 and is connected to both of them. The contraction section 321, the throat section 322 and the diffusion section 323 are all formed on the Venturi valve 320. Among them, the Venturi valve 320 is a relatively mature technology in the prior art, and the specific structure and working principle of the Venturi valve 320 will not be elaborated in this embodiment. The drinking water device in this embodiment directly uses the Venturi valve 320, which can omit the process of processing the pipeline, improve the processing efficiency and reduce the processing cost.
[0054] Optionally, a water inlet valve 500 is further arranged on the first water inlet pipeline 310 to control the on-off between the first water inlet pipeline 310 and the water source. In this embodiment, the water inlet valve 500 is an electromagnetic valve, which is convenient to use.
[0055] It can be understood that, in order to facilitate the user to access hot water, a part of hot water is usually stored in the hot water tank. When the liquid level of the water in the hot water tank reaches the preset minimum liquid level, the water inlet valve 500 is opened to supply water to the hot water tank. Therefore, after long-term use, there is always a part of stale water in the hot water tank. To solve this problem, the drinking water device further includes a drainage assembly 600. The drainage assembly 600 is communicatively connected to the water inlet valve 500 and can empty the water in the hot water tank to update the water in the hot water tank, avoiding the situation of long-term existence of stale water in the hot water tank, thereby ensuring the water use safety of the user.
[0056] Specifically, a drainage port 111 is arranged at the bottom of the hot water tank. The drainage assembly 600 includes a drainage pipeline and a drainage valve arranged on the drainage pipeline. The drainage pipeline is communicated with the drainage port 111. The drainage valve is communicatively connected to the control module of the drinking water device, and the control module can start the drainage valve according to a preset program to empty the water in the hot water tank after the drinking water device has been used for a preset time and when the water inlet valve 500 is closed. In this embodiment, the drainage valve is an electromagnetic valve.
[0057] Optionally, the inner bottom wall of the hot water tank gradually slopes downward along the direction close to the drainage port 111 to guide the water in the hot water tank and ensure that all the water in it is emptied when the drainage valve is opened.
[0058] Note that the above is only the preferred embodiment of the present utility model and the applied technical principles. Those skilled in the art will understand that the present utility model is not limited to the specific embodiments described herein, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present utility model. Therefore, although the present utility model has been described in detail through the above embodiments, the present utility model is not limited to the above embodiments. Without departing from the concept of the present utility model, more other equivalent embodiments can be included, and the scope of the present utility model is determined by the scope of the appended claims.
