Description
Technical Field
[0001] This utility model relates to the field of drinking water equipment technology, and in particular to an anti-jet buffer device. Background Technology
[0002] Drinking water equipment is a water treatment device that performs deep filtration and purification of water. It typically features hot water output and includes an inlet, solenoid valve, booster pump, filter assembly, DC pump, heating assembly (heating element), and hot water outlet. The booster pump pressurizes room-temperature water from the inlet into the reverse osmosis membrane filter of the filter assembly to obtain pure water. This pure water is then regulated by the DC pump and heated in the heating assembly. The heated water is then output from the hot water outlet. However, due to the power limitations of the heating assembly (heating element), the DC pump needs to operate at a very low flow rate (generally no more than 400mL) to heat room-temperature water to hot water (above 90℃). This can easily cause flow interruptions and jetting, negatively impacting the user experience and indicating room for improvement. Utility Model Content
[0003] The present invention aims to overcome the defects in the prior art by providing an anti-jet buffer device, which is installed between the heating component and the hot water outlet. It effectively avoids the problems of jetting and flow interruption through the buffering effect of the buffer chamber, and controls the water flow rate by adjusting the flow area of the outlet through the flow regulating component.
[0004] To achieve the above objectives, this utility model provides an anti-jet buffer device, which is installed on the hot water line of a drinking water device and located between the heating component and the hot water outlet. It includes a housing, a buffer chamber and a flow regulating component installed inside the housing. The buffer chamber is a relatively closed cavity structure and is provided with an inlet connected to the heating component and an outlet connected to the hot water outlet. The buffer chamber is configured such that the hot water flowing in through the inlet accumulates and overflows from the outlet. The flow regulating component is used to regulate the outflow rate of the liquid outlet, and includes a drive component with a telescopic rod and a blocking module connected to the telescopic rod. The blocking module is used at least to regulate the flow area of the liquid outlet in a blocking manner.
[0005] Further configuration: the driving component is located below the buffer chamber, the bottom wall of the buffer chamber is provided with a drain outlet, and the sealing module includes a first sealing block connected to the telescopic rod and used to cooperate in sealing the drain outlet, a second sealing block used to adjust and control the flow area of the liquid outlet, and a connecting rod connecting the first sealing block and the second sealing block. A drainage channel for drainage is constructed between the outer shell and the buffer cavity.
[0006] A further provision is made: the inner wall of the buffer cavity is provided with a slide rail that cooperates with the second sealing block to constrain its directional sliding.
[0007] A further configuration is provided: the driving component is an electric push rod.
[0008] The buffer cavity is further configured such that its exterior is covered with thermal insulation material.
[0009] The further configuration is as follows: the liquid inlet is located on the top wall of the buffer chamber, and the liquid outlet is located on the upper part of the side wall of the buffer chamber.
[0010] Compared with the prior art, this utility model has a simple and reasonable structure. It uses a buffer chamber to allow the liquid to be discharged in an accumulation and overflow manner, which has a buffering effect and can effectively avoid the problems of jetting and flow interruption. At the same time, the telescopic rod of the drive component drives the sealing module to move to switch between the flow regulation state and the residual water discharge state. In the flow regulation state, the drive component drives the second sealing block to move up and down to adjust the flow area of the liquid outlet to control the water flow. In the residual water discharge state, the drain is opened to discharge the residual water in the buffer chamber to ensure water safety. Attached Figure Description

Detailed Implementation
[0013] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0014] This utility model relates to a drinking water device, such as... Figure 1 As shown, the device includes an inlet 1, a solenoid valve 2, a booster pump 3, a filter assembly 4, a DC pump 5, a heating assembly 6, a hot water outlet 7, and an anti-jet buffer device 8 installed between the heating assembly 6 and the hot water outlet 7. The filter assembly 4 includes a reverse osmosis membrane filter element. When the drinking water device is producing hot water, the solenoid valve 2, the booster pump 3, the DC pump 5, and the heating assembly 6 are opened. The pressure from the booster pump 3 forces room temperature water from the inlet 1 into the reverse osmosis membrane filter element of the filter assembly 4. The concentrated water produced by the reverse osmosis membrane filtration is discharged through the concentrated water outlet of the reverse osmosis membrane filter element. The pure water produced is pumped by the DC pump 5 and flows sequentially through the heating assembly 6 and the anti-jet buffer device 8 before being output from the hot water outlet 7. The anti-jet buffer device 8 prevents jetting and flow interruption problems through buffering.
[0015] In this embodiment, the anti-jet buffer device 8 is as follows: Figure 2 and Figure 3 As shown, it includes an insulating shell 81, a buffer cavity 82 and a flow regulating component 83 disposed within the shell 81; wherein, the buffer cavity 82 is a relatively closed cavity structure and is provided with an inlet 821 connected to the heating component 6 and an outlet 822 connected to the hot water outlet 7. The inlet 821 is disposed on the top wall of the buffer cavity 82 and the outlet 822 is disposed on the upper part of the side wall of the buffer cavity 82. The buffer cavity 82 is configured such that the hot water flowing in through the inlet 821 flows out from the outlet 822 in an accumulated overflow manner. The anti-jet buffer device 8 can avoid the occurrence of jetting and flow interruption problems through the buffer cavity 82.
[0016] In this embodiment, as Figure 2 and Figure 3 As shown, the flow regulating component 83 is arranged at the outlet 821 of the buffer chamber 82 to regulate the outflow rate of the outlet 821. It includes a drive component 831 with a telescopic rod 8311 and a blocking module 832 connected to the telescopic rod 8311. The blocking module 832 is used at least to regulate the flow area of the outlet 821 by blocking, thereby controlling the telescopic rod 8311 to move the blocking module 832 and thus regulating the outflow rate of the outlet 821. Specifically, the drive component 831 is located in the buffer chamber 82. Below, the bottom wall of the buffer chamber 82 is provided with a drain outlet 823. The sealing module 832 includes a first sealing block 8321 connected to the telescopic rod 8311 and used to seal the drain outlet 823, a second sealing block 8322 used to adjust and control the flow area of the outlet 821, and a connecting rod 8323 connecting the first sealing block 8321 and the second sealing block 8322. Thus, the driving component 831 drives the telescopic rod 8311 to move the sealing module 832 up and down, which can control the anti-jet buffer device 8 in the flow regulation state. Figure 2) and residual water discharge status ( Figure 3 Switch between )
[0017] like Figure 2 As shown, when the device 8 is in the flow regulation state, the first sealing block 8321 always moves within the drain outlet 823 to ensure that the drain outlet 823 is always in a closed state. In this state, the driving component 831 can adjust the flow area of the liquid outlet 821 by driving the second sealing block 8322 to move up and down, thereby achieving the purpose of controlling the water flow rate.
[0018] like Figure 3 As shown, when the device 8 is in the residual water discharge state, the first sealing block 8321 is pulled down to below the drain outlet 823 by the driving component 831, and the second sealing block 8322 is located below the liquid outlet 822. At this time, the drain outlet 823 of the buffer chamber 82 is in the open state, and the residual water in the buffer chamber 82 can be discharged through the drain outlet 823. Preferably, a drainage channel 811 for discharging residual water to the outside of the housing 81 is constructed between the housing 81 and the buffer chamber 82, so as to ensure water safety.
[0019] In the above scheme, the inner wall of the buffer cavity 82 is provided with a slide rail 833 for cooperating with the second sealing block 8322 to constrain its directional sliding, thereby ensuring the reliability and stability of the movement of the sealing module 832.
[0020] In this embodiment, the buffer cavity 82 is wrapped with a heat-insulating material 84, which can reduce heat loss.
[0021] In this embodiment, the drive component 831 is a fully waterproof electric push rod. In other solutions, a cylinder or a hydraulic cylinder can also be used.
[0022] Compared with the prior art, this utility model has a simple and reasonable structure. It uses a buffer chamber to allow the liquid to be discharged in an accumulation and overflow manner, which has a buffering effect and can effectively avoid the problems of jetting and flow interruption. At the same time, the telescopic rod of the drive component drives the sealing module to move to switch between the flow regulation state and the residual water discharge state. In the flow regulation state, the drive component drives the second sealing block to move up and down to adjust the flow area of the liquid outlet to control the water flow. In the residual water discharge state, the drain is opened to discharge the residual water in the buffer chamber to ensure water safety.
[0023] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
