[0002] In current life, the use of instant water heaters has become popular. Compared with traditional electric water heaters, instant water heaters have the advantages of fast hot water output and more convenient use, and are deeply loved by consumers.

[0003] That is, a heating tube is provided in the water heater, which heats the water and then sends it out through the water nozzle. Since the hot water is mixed with gas, after the hot water is sent into the water nozzle, it is affected by the air pressure in the water nozzle, resulting in a flow interruption when the water flows out of the water nozzle. In addition, the size of the water nozzle will affect the water type. If the water output is small (when hot water is output), it is easy to have problems of erratic and scattered water flow. However, when a larger water output is required, the size of the water nozzle is fixed, which leads to a longer water output speed. If the size of the water outlet of the water nozzle is increased, it is easy for the water to flow out unsmoothly and drift randomly. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a water nozzle structure for instant water heaters to prevent hot water from splashing in view of the current status of the prior art.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 5 As shown, a faucet structure for an instant water heater includes: a shell 1 and a faucet body 2.

[0026] Specifically, a cavity 100 is formed in the shell 1, and a water inlet 101 is provided on one side wall of the shell 1, and an outlet 102 is provided at the bottom of the shell 1, and the water inlet 101 is communicated with the outlet 102 through the cavity 100, and the faucet body 2 is arranged in the cavity 100 and formed with a vent hole 206, and the vent hole 206 is used to discharge the gas in the cavity 100, and the faucet body 2 is provided with a first water outlet pipe 200, and the first water outlet pipe 200 is vertically arranged along the height direction of the shell 1. The first water outlet pipe 200 passes through the outlet 102, and the first water outlet pipe 200 is connected to the water inlet 101 through the cavity 100. In this embodiment, three second water outlet pipes 201 are evenly arranged on the faucet body 2, but it is not limited to three, and it can also be four, five, etc., and it is preset according to the size and structure of the faucet body 2. The second water outlet pipe 201 is parallel to the first water outlet pipe 200 and is arranged along the height direction of the shell 1 and is in the cavity 100. The second water outlet pipe 201 The outlet 102 is connected to the second water outlet pipe 201, and a drainage groove 202 is provided on the end of the second water outlet pipe 201 away from the outlet 102. The drainage grooves 202 of the three second water outlet pipes 201 are all on the same horizontal plane. When normal temperature water enters the cavity 100 from the water inlet 101, the pressure in the cavity 100 is also small, and the water will be discharged smoothly from the first water outlet pipe 200. When hot water with a small flow rate enters the cavity 100 from the water inlet 101, the cavity 100 is filled with hot air because the hot water is mixed with hot air. The pressure in the cavity 100 is relatively high, and the gas is discharged from the vent hole 206. The hot water with a smaller flow rate will be discharged smoothly from the first water outlet pipe 200. When the hot water with a larger flow rate enters the cavity 100 from the water inlet 101, the hot water overflows the first water outlet pipe 200 to the second water outlet pipe 201. The hot water flows into the second water outlet pipe 201 through the drainage groove 202, which increases the water output of the water nozzle and gathers the hot water flowing out of the outlet 102 to ensure that the hot water does not float or spill.

[0027] It is worth mentioning that when the hot water output is small, the gas in the hot water entering from the water inlet 101 can also be discharged along the second water outlet pipe 201 to ensure that the hot water flows smoothly out of the first water outlet pipe 200.

[0028] Specifically, Figure 3 and Figure 4 As shown, a guide sleeve 203 is provided on the faucet body 2, and the guide sleeve 203 is sleeved on the first water outlet pipe 200 and located in the outlet 102, an annular guide hole 204 is formed between the guide sleeve 203 and the first water outlet pipe 200, the second water outlet pipe 201 is connected to the annular guide hole 204, an exhaust groove 205 is formed between the guide sleeve 203 and the outlet 102, and the exhaust groove 205 is connected to the vent 206.

[0029] The guide sleeve 203 is sleeved on the first water outlet pipe 200 and located in the outlet 102, and the guide sleeve 203 is located between the outlet 102 and the first water outlet pipe 200, dividing the gap between the outlet 102 and the first water outlet pipe 200, so that an annular guide hole 204 is formed between the guide sleeve 203 and the first water outlet pipe 200. The function of the annular guide hole 204 is to converge and drain the water flowing out of the cavity 100 from the three second water outlet pipes 201. The guide sleeve 203 and the outlet 102 form an exhaust groove 205. The exhaust groove 205 is used to discharge the gas in the cavity 100, reduce the pressure in the cavity, and ensure that the hot water does not float or spill when it is discharged.

[0030] Furthermore, if Figure 4 and Figure 5 As shown, a plurality of arc grooves 209 are formed on the faucet body 2, the faucet body 2 abuts against the cavity wall of the cavity 100, and air holes 206 are formed between the arc grooves 209 and the cavity wall of the cavity 100, the opening of the drainage groove 202 faces between two adjacent air holes 206, and the air holes 206 are connected to the exhaust groove 205.

[0031] The faucet body 2 is pressed against the wall of the cavity 100. Since the periphery of the faucet body 2 is in the shape of petals due to the design of several arc-shaped grooves 209, part of the surface wall of the faucet body 2 is pressed against the wall of the cavity 100, and the arc-shaped grooves 209 and the wall of the cavity 100 form air vents 206. When hot water enters the cavity 100 through the water inlet 101, the gas entrained by the hot water can be discharged through these air vents 206, so that the air pressure in the cavity 100 is close to or equal to the external air pressure.

[0032] Furthermore, if Figures 3 to 5 As shown, a first annular clamping portion 207 is provided on the faucet body 2, a second annular clamping portion 208 is provided on the guide sleeve 203, the second annular clamping portion 208 is clamped with the first annular portion, and a first limiting portion 109 is provided on the outlet 102, a second limiting portion 110 is provided on the guide sleeve 203, and the second limiting portion 110 abuts against the first limiting portion 109.

[0033] The guide sleeve 203 is located between the outlet 102 and the first water outlet pipe 200, and the second annular clamping portion 208 at the upper end of the guide sleeve 203 is clamped together with the first annular clamping portion 207 on the faucet body 2, thereby dividing the gap between the outlet 102 and the first water outlet pipe 200. However, in order to prevent the guide sleeve 203 from detaching from the faucet body 2 due to the impact of water when the water in the second water outlet pipe 201 flows toward the annular guide hole 204, a first limiting portion 109 is provided on the outlet 102, and a second limiting portion 110 is provided at the lower end of the guide sleeve 203. The second limiting portion 110 is clamped together with the first limiting portion 109, so that the guide sleeve 203 will not be detached from the faucet body 2 due to force.

[0034] Specifically, Figure 2 and Figure 4 As shown, a dividing plate 103 is provided in the water inlet 101 , and the dividing plate 103 is used to disperse the gas in the water sent into the cavity 100 .

[0035] When hot water flows into the cavity 100 from the water inlet 101, it will be mixed with gas, which will cause the hot water to float and splash when the first water outlet pipe 200 discharges water alone or the first water outlet pipe 200 and the second water outlet pipe 201 discharge water at the same time. A cross-shaped dividing plate 103 is provided in the water inlet 101, which can effectively disperse the gas entrained in the hot water sent into the cavity 100 in advance to ensure the stability of the water flow when discharging water.

[0036] It should be noted that the partition plate 103 in this embodiment is not limited to a cross shape, and may also be other fence-shaped, diamond-shaped, and other shapes.

[0037] Specifically, Figure 3 As shown, the housing 1 has an upper cover 104 and a lower shell 105 , the faucet body 2 is located in the lower shell 105 , and a baffle 108 is provided on the upper cover 104 . The baffle 108 is disposed in the cavity 100 and located at the water inlet 101 .

[0038] The separate design of the upper cover 104 and the lower shell 105 can facilitate the disassembly and assembly of the guide sleeve 203 and the faucet body 2. The upper cover 104 and the lower shell 105 are connected together by bolts and snaps to form a cavity 100, and a baffle 108 is provided on the upper cover 104. The baffle 108 is arranged in the cavity 100 and is located near the water inlet 101. When external hot water enters the cavity 100 through the water inlet 101, the impact of the hot water is relatively large. The baffle 108 can prevent the hot water from splashing, and the baffle 108 can help disperse the gas entrained in the hot water to ensure the stability of the water flow when the water is discharged.

[0039] Furthermore, if Figure 1 and Figure 3 As shown, a connecting portion 106 is provided on the outer wall of the lower shell 105, and the connecting portion 106 can be conveniently connected to a preset device by bolts.

[0040] A pair of connecting parts 106 are provided on the outer wall of the lower shell 105, and the pair of connecting parts 106 are symmetrically arranged along the first water outlet pipe 200. Users can conveniently connect with the preset equipment through bolts through the connecting parts 106, so that the faucet structure is suitable for different styles of instant water heaters.

[0041] Furthermore, if Figures 1 to 4As shown, an exhaust pipe 107 is provided on the upper cover 104, and the exhaust pipe 107 is connected to the cavity 100. The exhaust pipe 107 can be connected to an external water tank to discharge the gas generated when heating water in the water tank.

[0042] In this embodiment, an exhaust pipe 107 is provided on the upper cover 104, and the exhaust pipe 107 can be connected to the water tank of the external instant water heater, so that when the instant water heater heats the water, the gas generated during the boiling process of the water can first flow into the exhaust pipe 107 through the pipeline and be discharged from the exhaust groove 205, so as to ensure that when the subsequent hot water enters the cavity 100 through the water inlet 101, the air pressure in the cavity remains within a preset range, and is conducive to the stability of the water flow during the subsequent water discharge.
