[0001] The utility model relates to the field of cooking utensils, and particularly relates to a liquid heating device. BACKGROUND

[0002] In the liquid heating device of the related art, a power switch is usually arranged on the handle, a steam switch is arranged inside the handle, and a steam passage is arranged between the handle and the container body. During the heating process, as the temperature of the liquid in the container body rises, the steam generated by the liquid flows to the steam passage for exhaust and pressure relief, and flows through the steam switch, which is de-energized under the influence of the steam temperature, to control the liquid heating device to stop heating. However, since the steam enters the inside of the handle, condensate water is easily generated at the gap between the handle and the power switch, which affects the user experience. SUMMARY

[0003] Therefore, the utility model aims to provide a liquid heating device, which can reduce the probability of condensate water appearing on the outer surface of the handle assembly.

[0005] The liquid heating device provided by the aspect of the utility model can discharge part of the steam generated in the container body along the main steam passage and make another part of the steam enter the inside of the steam box through the steam inlet during the heating process, so that the steam switch can perform corresponding actions under the influence of the steam temperature and be discharged through the steam outlet and the auxiliary steam passage. Since the steam switch is hidden in the steam box, the steam cannot leak to the space surrounded by the handle main body and the handle cover, the probability of condensate water appearing on the outer surface of the handle assembly can be reduced, the probability of condensate water accumulating in the space surrounded by the handle main body and the handle cover can be reduced, the temperature of the outer surface of the handle assembly can be prevented from being too high, and the risk of user scalding can be reduced. In addition, the steam box is arranged to block the live parts, so that the probability of user electric shock can be reduced.

[0006] Further, in some embodiments, the handle assembly further comprises: a steam switch wire, one end of the steam switch wire extending into the steam box and electrically connected with the steam switch, the other end of the steam switch wire extending downward through the auxiliary steam channel and used for connecting with the power supply.

[0007] In these embodiments, the steam switch wire is arranged in the auxiliary steam channel, and the steam temperature in the auxiliary steam channel is relatively low, which is verified to be below 75℃ and will not exceed the temperature generated by the power-on of the steam switch wire, especially, the steam temperature is lower and lower along the auxiliary steam channel, the steam can take away the heat generated by the wire during the flow, so that the wire can be cooled and the product use safety can be improved.

[0008] Further, in some embodiments, the steam box is further provided with a condensed water outlet, the condensed water outlet being communicated with the main steam channel to discharge the condensed water in the steam box into the main steam channel.

[0009] In these embodiments, the condensed water outlet is arranged on the steam box to facilitate the discharge of the condensed water in the steam box, avoid the accumulation of water in the steam box, and improve the product use safety. In addition, the condensed water outlet is communicated with the main steam channel, so that the condensed water is discharged through the main steam channel instead of the auxiliary steam channel where the steam switch wire is located, so that the water and electricity are separated, and the safety is improved.

[0010] Further, in some embodiments, the steam box has a steam guide channel and a wire guide channel which are independent of each other, the steam inlet, the steam outlet and the condensed water outlet are all communicated with the steam guide channel, the steam switch can be in contact with the steam in the steam guide channel, and one end of the steam switch wire extends into the wire guide channel and is electrically connected with the steam switch.

[0011] In these embodiments, the steam box has the steam guide channel and the wire guide channel which are independent of each other and do not affect each other, so that the steam in the steam guide channel can be prevented from entering the wire guide channel in large quantities to cause safety hazards.

[0012] Further, in some embodiments, the steam inlet, the steam outlet and the condensed water outlet are all arranged on the box wall of the side wall of the steam box facing the container body. The steam inlet is communicated with the main steam channel, the steam outlet is communicated with the auxiliary steam channel, and the condensed water outlet is communicated with the main steam channel.

[0013] Further, in some embodiments, the steam inlet is higher than the steam outlet. Since the steam temperature is high, the steam will naturally rise, so that the steam outlet is lower than the steam inlet, the speed of the steam flowing through the steam box is slowed down, so that the steam switch can be in full contact with the steam to realize the power-off function.

[0014] Further, in some embodiments, the condensed water outlet is lower than the steam inlet and is arranged at the bottom of the steam guide channel. Accumulation of condensed water in the steam box can be avoided.

[0015] Further, in some embodiments, a shielding cover is arranged on the outer wall of the steam box, the shielding cover covers the condensed water outlet on the outer side of the steam box, and an opening is arranged on the side of the shielding cover facing the bottom of the container body, the opening being in communication with the main steam channel.

[0016] In these embodiments, by designing a shielding cover to shield the condensed water outlet, the condensed water outlet can be prevented from directly facing the main steam channel, so that the hot steam in the main steam channel can not enter the steam box in large quantities through the condensed water outlet. The shielding cover can block the hot steam. Moreover, the shielding cover does not affect the discharge of the condensed water, and the condensed water in the steam box can flow into the main steam channel through the condensed water outlet and the opening on the shielding cover.

[0017] Further, in some embodiments, the steam guide channel is arranged above the wire guide channel, a through hole is arranged on the wall of the steam box facing the bottom of the container body, and the steam switch wire extends into the auxiliary steam channel through the through hole.

[0018] In these embodiments, the steam guide channel is arranged above the wire guide channel, and the two are relatively independent and do not affect each other. The through hole is arranged on the wall of the steam box facing the bottom of the container body, so that the steam switch wire can pass through the through hole from bottom to top to be electrically connected with the steam switch, and the steam switch wire can smoothly extend downward into the auxiliary steam channel. The wiring is reasonable, the length of the steam switch wire can be shortened, the material can be reduced, and the cost can be saved.

[0019] Further, in some embodiments, the steam guide channel is formed between the upper part of the side of the steam switch facing the side wall of the container body and the wall of the steam box, the lower part of the side of the steam switch facing the side wall of the container body is in close contact with the wall of the steam box, and the wire guide channel is formed between the side of the steam switch facing the bottom of the container body and the wall of the steam box.

[0020] In these embodiments, the steam switch directly surrounds the steam guide channel and the wire guide channel with the wall of the steam box. On the one hand, it is beneficial for the steam switch to fully contact the steam in the steam guide channel and to be powered off in time. On the other hand, it is beneficial for the steam switch wire to extend into the wire guide channel without being blocked and to be directly electrically connected with the steam switch. Moreover, no additional structure or component is needed to separate the steam guide channel and the wire guide channel, so that the internal structure of the steam box can be simplified and the cost can be saved.

[0021] Further, in some embodiments, a first blocking rib is arranged on the inner wall of the steam box below the condensed water outlet, the first blocking rib extends in the direction of the steam switch, and is used for receiving and guiding the condensed water to flow to the condensed water outlet. The design of the first blocking rib facilitates the outflow of the condensed water from the steam box.

[0022] Further, in some embodiments, the first section of the main steam passage and the first section of the auxiliary steam passage are formed between the steam box and the side wall of the container body, the first section of the main steam passage and the first section of the auxiliary steam passage are arranged side by side in the horizontal direction, the steam inlet is communicated with the first section of the main steam passage, and the steam outlet is communicated with the first section of the auxiliary steam passage; the second section of the main steam passage and the second section of the auxiliary steam passage are formed between the portion of the handle body lower than the steam box and the side wall of the container body, the lower end of the first section of the main steam passage is communicated with the upper end of the second section of the main steam passage, and the lower end of the first section of the auxiliary steam passage is communicated with the upper end of the second section of the auxiliary steam passage; wherein the main steam passage includes the first section of the main steam passage and the second section of the main steam passage, and the auxiliary steam passage includes the first section of the auxiliary steam passage and the second section of the auxiliary steam passage.

[0023] In these embodiments, the main steam passage includes the first section of the main steam passage between the steam box and the side wall of the container body and the second section of the main steam passage between the handle body and the side wall of the container body, and the auxiliary steam passage includes the first section of the auxiliary steam passage between the steam box and the side wall of the container body and the second section of the auxiliary steam passage between the handle body and the side wall of the container body, since the steam box directly forms part of the steam passage with the side wall of the container body, it is convenient for the steam in the main steam passage to enter the steam box, and it is also convenient for the steam in the steam box to enter the auxiliary steam passage.

[0024] Further, in some embodiments, the steam box is arranged obliquely away from the container body, and the top of the steam box is away from the container body relative to the bottom of the steam box. Since the steam box directly forms the first section of the main steam passage and the first section of the auxiliary steam passage between the steam box and the side wall of the container body, the steam box is arranged obliquely, which can increase the top space of the first section of the main steam passage and the first section of the auxiliary steam passage, form a passage that is large at the top and small at the bottom, and be conducive to the passage of steam.

It is convenient to guide the steam into the main steam passage and the auxiliary steam passage, and the steam box occupies a small space, which is convenient to arrange in the handle body without interfering with the elbow at the upper part of the handle body.

[0026] Further, in some embodiments, the width of at least one of the first section of the main steam passage and the second section of the main steam passage gradually increases from top to bottom. It is conducive to the rapid passage of steam through the main steam passage, thereby reducing the temperature outside the handle assembly.

[0027] Further, in some embodiments, the number of auxiliary steam passages is two, which are distributed on both sides of the width direction of the main steam passage. The number of steam switch wires is two, which respectively extend downward through one auxiliary steam passage. It is convenient for the steam switch to be connected into a loop with the heating element of the liquid heating device and the power supply.

[0028] Further, in some embodiments, the steam box is provided with a second blocking rib extending downward at the side bottom of the steam box away from the side wall of the container body, which is fitted with the side wall of the handle body to block the steam from entering the gap between the steam box and the handle body. The design of the second blocking rib can block the steam from directly transferring heat to the handle body, reducing the risk of scalding for the user.

[0029] Further, in some embodiments, the inside of the container body includes a containing cavity capable of containing liquid and a mounting cavity located below the containing cavity, the upper part of the cavity side wall of the containing cavity is provided with an exhaust port, which is in communication with the main steam channel; the cavity side wall of the mounting cavity is provided with a first through hole and a second through hole, the first through hole is in communication with the main steam channel, and the second through hole is in communication with the auxiliary steam channel, the steam switch lead wire extends into the mounting cavity through the second through hole and is electrically connected with the temperature controller in the mounting cavity.

[0068] The following will be described in conjunction with Figures 1 to 16The embodiment of the utility model provides a liquid heating device. Wherein, the handle assembly 2 and the side wall of the container body 1 form the main steam channel 3 and the auxiliary steam channel 4. The steam channel marked on the container body 1 is part of the main steam channel 3 and the auxiliary steam channel 4, and the steam channel marked on the handle body 210 and the steam box 220 is also part of the main steam channel 3 and the auxiliary steam channel 4. Therefore, the same mark is marked on the corresponding part of the steam channel of the container body 1, the handle body 210 and the steam box 220 for easy understanding.

[0069] As shown in Figures 1 to 5 , Figures 11 to 15 The utility model discloses a liquid heating device, which comprises a container body 1 and a handle assembly 2 arranged on the side wall of the container body 1. The handle assembly 2 and the side wall of the container body 1 form a main steam channel 3 and an auxiliary steam channel 4. The main steam channel 3 and the auxiliary steam channel 4 are arranged side by side in the horizontal direction and both extend to the bottom of the container body 1. The main steam channel 3 can communicate with the inner cavity of the container body 1. The handle assembly 2 comprises a handle body 210 connected with the side wall of the container body 1, a steam box 220 arranged on the upper side of the handle body 210 facing the container body 1, a steam inlet 2211 and a steam outlet 2212 arranged on the steam box 220, the steam inlet 2211 communicating with the main steam channel 3 so that the steam in the main steam channel 3 can enter the steam box 220 through the steam inlet 2211, the steam outlet 2212 communicating with the auxiliary steam channel 4 so that the steam in the steam box 220 can be discharged into the auxiliary steam channel 4 through the steam outlet 2212, and a steam switch 230 arranged in the steam box 220, which is used to cut off the power supply under the influence of the temperature of the steam in the steam box 220.

[0070] The liquid heating device provided by the embodiment of the utility model can discharge part of the steam generated in the container body 1 along the main steam channel 3 and the other part of the steam into the steam box 220 through the steam inlet 2211 during the heating process. The steam switch 230 can perform corresponding actions under the influence of the temperature of the steam, and the steam can be discharged through the steam outlet 2212 and the auxiliary steam channel 4. Since the steam switch 230 is hidden in the steam box 220, the steam will not leak into the space surrounded by the handle body 210 and the handle cover 250, which can reduce the probability of condensate water appearing on the outer surface of the handle assembly 2, reduce the probability of condensate water accumulating in the space surrounded by the handle body 210 and the handle cover 250, prevent the temperature of the outer surface of the handle assembly 2 from being too high, and reduce the risk of user scalding. In addition, the steam box 220 is arranged to block the live parts, which can also reduce the probability of user electric shock.

[0071] In addition, since the steam enters the steam box 220 through the main steam passage 3 and then enters the auxiliary steam passage 4, the steam temperature in the auxiliary steam passage 4 decreases rapidly, and after the steam switch 230 cuts off the power supply, cold air will also enter the steam box 220 from the auxiliary steam passage 4 in the reverse direction. Compared with only having the main steam passage 3, the internal temperature of the steam box 220 can be reduced more quickly, which is beneficial to quickly reset the steam switch 230 to the natural state. Of course, in the natural state, the steam switch 230 is still cut off. In this way, the user can press the power switch 260 again within a short time, and the power switch 260 drives the micro switch to act and power on.

[0072] Further, as shown in Figure 1 、 Figure 6 、 Figure 8 and Figure 16 , the handle assembly 2 further includes a handle cover 250 and a power switch 260. The handle cover 250 is arranged on the handle body 210, and the power switch 260 is movably arranged on the handle cover 250 and connected with the steam switch 230. When the power switch 260 moves to the open position, the power switch 260 can drive the steam switch 230 to open the power supply. When the steam switch 230 is cut off under the influence of steam, the steam switch 230 can simultaneously drive the power switch 260 to reset, so that the user can press the power switch 260 again.

[0073] Further, in some embodiments, as shown in Figure 1 、 Figure 4 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 12 , the handle assembly 2 further includes a steam switch wire 240. One end of the steam switch wire 240 extends into the steam box 220 and is electrically connected with the steam switch 230, and the other end of the steam switch wire 240 extends downward through the auxiliary steam passage 4 and is connected with the power supply.

[0074] In these embodiments, the steam switch wire 240 is arranged in the auxiliary steam passage 4. Since the steam temperature in the auxiliary steam passage 4 is relatively low, it has been verified that it will not exceed the temperature generated by the power-on of the steam switch wire 240, which is always below 75°C. In particular, the temperature of the steam decreases as it goes down along the auxiliary steam passage 4. The steam can carry away the heat generated by the wire during the flow process, so that the wire can be cooled, and the safety of the product in use can be improved.

[0075] In a specific application, the steam in the steam box 220 flows downward in the auxiliary steam passage 4 between the steam box 220 and the side wall of the container body 1 after flowing out through the steam outlet 2212. After flowing through the long and narrow auxiliary steam passage 4, the temperature of the steam is greatly reduced, and then the steam enters the auxiliary steam passage 4 in which the steam switch wire 240 is located, which is beneficial to heat dissipation of the steam switch wire 240.

[0076] In addition, compared with the steam switch wire 240 arranged in the space between the handle main body 210 and the handle cover 250 in the related art, the wire is conveniently arranged, and there is no need to additionally add a wire fixing structure in the space, which is beneficial to simplify the handle structure and save costs.

[0077] Further, in some embodiments, as shown in Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 14 and Figure 15 , the steam box 220 is further provided with a condensed water outlet 2213, which is in communication with the main steam passage 3 to discharge the condensed water in the steam box 220 into the main steam passage 3.

[0078] In these embodiments, the condensed water outlet 2213 is arranged on the steam box 220 to conveniently discharge the condensed water in the steam box 220, avoid water accumulation in the steam box 220, and improve the safety of product use. In addition, the condensed water outlet 2213 is in communication with the main steam passage 3, so that the condensed water is discharged through the main steam passage 3 instead of the auxiliary steam passage 4 in which the steam switch wire 240 is located, which realizes water and electricity diversion and improves safety.

[0079] Further, in some embodiments, as shown in Figures 7 to 9 、 Figure 11 and Figure 12 , the steam box 220 has a steam passage 223 and a wire passage 224 which are independent of each other, the steam inlet 2211, the steam outlet 2212 and the condensed water outlet 2213 are in communication with the steam passage 223, the steam switch 230 can be in contact with the steam in the steam passage 223, and one end of the steam switch wire 240 extends into the wire passage 224 and is electrically connected with the steam switch 230.

[0080] In these embodiments, the steam box 220 has the steam passage 223 and the wire passage 224 which are independent of each other and do not affect each other, so that the steam in the steam passage 223 can be prevented from entering the wire passage 224 in large quantities to cause a safety hazard.

[0081] It should be noted that the steam passage 223 and the wire passage 224 are independent of each other, and the two can be completely separated and not connected to each other, for example, the two are blocked by a sealing member or a blocking member, or the two can be connected through the assembly gap of several components, as long as a large amount of steam cannot enter the steam passage 223, and the two do not affect each other.

[0082] Further, as shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 , the steam inlet 2211, the steam outlet 2212 and the condensed water outlet 2213 are all arranged on the box wall of the steam box 220 facing the side wall of the container body 1. The steam inlet 2211 is in communication with the main steam passage 3, the steam outlet 2212 is in communication with the auxiliary steam passage 4, and the condensed water outlet 2213 is in communication with the main steam passage 3.

[0083] As an example, as shown in Figure 4 and Figure 5 , the steam box 220 includes a steam box front cover 221 and a steam box rear cover 222, the steam box front cover 221 is closer to the container body 1 than the steam box rear cover 222, and the steam box front cover 221 and the steam box rear cover 222 enclose the internal space of the steam box 220. The steam box 220 is spliced into two parts, which facilitates the installation of the steam switch 230 inside. The steam inlet 2211, the steam outlet 2212 and the condensed water outlet 2213 are all arranged on the steam box front cover 221.

[0084] Further, as shown in Figure 3 、 Figure 5 and Figure 7 , the steam inlet 2211 is higher than the steam outlet 2212. Because the steam temperature is high, it will naturally rise, so that the steam outlet 2212 is lower than the steam inlet 2211, which facilitates slowing down the speed of the steam flowing through the steam box 220, so that the steam switch 230 can fully contact the steam and realize the function of power-off.

[0085] Further, as shown in Figure 3 and Figure 5 , the condensed water outlet 2213 is lower than the steam inlet 2211 and is arranged at the bottom of the steam passage 223. It can avoid the accumulation of condensed water in the steam box 220.

[0086] Further, as shown in Figure 3 、 Figures 5 to 7As shown, the outer wall of the steam box 220 is provided with a shielding cover 2214, which covers the condensate outlet 2213 on the outer side of the steam box 220, and the shielding cover 2214 is provided with an opening on the side facing the bottom of the container body 1, which communicates with the main steam channel 3. The shielding cover 2214 can block the hot steam, so that the hot steam in the main steam channel 3 does not enter the steam box 220 through the condensate outlet 2213. Moreover, the shielding cover 2214 does not affect the discharge of the condensate, and the condensate in the steam box 220 can flow into the main steam channel 3 through the condensate outlet 2213 and the opening on the shielding cover 2214.

[0087] Further, as shown in Figure 8 and Figure 9 , the steam guide channel 223 is located above the wire guide channel 224, and the steam box 220 is provided with a through hole on the wall facing the bottom of the container body 1, and the steam switch wire 240 extends into the auxiliary steam channel 4 through the through hole.

[0088] Here, the steam guide channel 223 is arranged above the wire guide channel 224, and the two are relatively independent and do not affect each other. The steam box 220 is provided with a through hole on the wall facing the bottom of the container body 1, so that the steam switch wire 240 can pass through the through hole from bottom to top and be electrically connected to the steam switch 230 in the wire guide channel 224. Moreover, the steam switch wire 240 can smoothly extend downward into the auxiliary steam channel 4, and the wiring is reasonable, which can shorten the length of the steam switch wire 240, reduce the material, and save the cost.

[0089] As an example, as shown in Figure 8 and Figure 9 , the steam guide channel 223 is formed between the upper part of the side wall of the steam switch 230 facing the container body 1 and the wall of the steam box 220, the lower part of the side wall of the steam switch 230 facing the container body 1 is in close contact with the wall of the steam box 220, and the wire guide channel 224 is formed between the side wall of the steam switch 230 facing the bottom of the container body 1 and the wall of the steam box 220.

[0090] In this example, the steam switch 230 directly surrounds the steam guide channel 223 and the wire guide channel 224 with the wall of the steam box 220, which is beneficial for the steam switch 230 to fully contact the steam in the steam guide channel 223 and turn off the power in time, and the steam switch wire 240 can be electrically connected to the steam switch 230 without being blocked after extending into the wire guide channel 224. Moreover, no additional structure or component is needed to separate the steam guide channel 223 and the wire guide channel 224, which can simplify the internal structure of the steam box 220 and save the cost.

[0091] The steam switch 230 can be recessed towards the upper side of the side wall of the container body 1, or the box wall of the steam box 220 can be partially convex, so as to form the steam guide channel 223 between the two. The steam switch 230 is attached to the lower side of the side wall of the container body 1, and the box wall of the steam box 220 can be tightly attached or have a certain assembly gap. However, even if there is an assembly gap, steam in the steam guide channel 223 will not enter the wire guide channel 224 in large quantities, and the steam guide channel 223 and the wire guide channel 224 are almost independent of each other, which can be ignored.

[0092] Further, as shown in Figure 9 , the first blocking rib 2215 can be further arranged below the condensate outlet 2213 on the inner wall of the steam box 220, and the first blocking rib 2215 extends towards the steam switch 230, and is used for receiving and guiding the condensate to flow to the condensate outlet 2213. The first blocking rib 2215 is designed to facilitate the condensate to flow out of the steam box 220.

[0093] In addition, in the case where the steam switch 230 directly surrounds the steam guide channel 223 and the wire guide channel 224 with the box wall of the steam box 220, the first blocking rib 2215 extends towards the steam switch 230, for example, is attached to the steam switch 230, and the first blocking rib 2215 can also be used to block the assembly gap between the lower part of the steam switch 230 and the steam box 220, so as to prevent the steam in the steam guide channel 223 from entering the wire guide channel 224.

[0094] As an example, the first blocking rib 2215 extends from the lower edge of the condensate outlet 2213 to the inside of the steam box 220, and can extend horizontally or be curved upwards, so as to facilitate the condensate to flow to the condensate outlet 2213.

[0095] Further, in some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 13As shown, the steam box 220 and the side wall of the container body 1 form a first section of the main steam passage 310 and a first section of the auxiliary steam passage 410, which are arranged side by side in the horizontal direction, the steam inlet 2211 communicates with the first section of the main steam passage 310, and the steam outlet 2212 communicates with the first section of the auxiliary steam passage 410; the lower part of the handle body 210 and the side wall of the container body 1 form a second section of the main steam passage 320 and a second section of the auxiliary steam passage 420, the lower end of the first section of the main steam passage 310 communicates with the upper end of the second section of the main steam passage 320, and the lower end of the first section of the auxiliary steam passage 410 communicates with the upper end of the second section of the auxiliary steam passage 420; wherein the main steam passage 3 includes the first section of the main steam passage 310 and the second section of the main steam passage 320, and the auxiliary steam passage 4 includes the first section of the auxiliary steam passage 410 and the second section of the auxiliary steam passage 420.

[0096] In these embodiments, the main steam passage 3 includes the first section of the main steam passage 310 between the steam box 220 and the side wall of the container body 1, and the second section of the main steam passage 320 between the handle body 210 and the side wall of the container body 1, and the auxiliary steam passage 4 includes the first section of the auxiliary steam passage 410 between the steam box 220 and the side wall of the container body 1, and the second section of the auxiliary steam passage 420 between the handle body 210 and the side wall of the container body 1, since the steam box 220 directly surrounds part of the steam passage with the side wall of the container body 1, it is convenient for the steam in the main steam passage 3 to enter the steam box 220, and it is also convenient for the steam in the steam box 220 to enter the auxiliary steam passage 4.

[0097] In specific applications, as shown in Figure 1 、 Figure 2 and Figure 3 , a plurality of first ribs 110 can be arranged on the side wall of the container body 1, a plurality of second ribs 2216 can be arranged on the box wall of the steam box 220, and a plurality of third ribs 211 can be arranged on the side wall of the handle body 210, the upper part of the plurality of first ribs 110 cooperates with the plurality of second ribs 2216 to separate the space between the steam box 220 and the container body 1 into the first section of the main steam passage 310 and the first section of the auxiliary steam passage 410, and the lower part of the plurality of first ribs 110 cooperates with the plurality of third ribs 211 to separate the space between the handle body 210 and the container body 1 into the second section of the main steam passage 320 and the second section of the auxiliary steam passage 420. The first ribs 110 and the second ribs 2216 can be butt-jointed together, or the side wall of the first ribs 110 can be tightly fitted with the side wall of the second ribs 2216 to avoid steam leakage. Similarly, the first ribs 110 can also be butt-jointed with the third ribs 211, or the side wall of the first ribs 110 can be tightly fitted with the side wall of the third ribs 211 to avoid steam leakage.

[0098] As an example, as shown in Figure 2 , Figure 3 and Figure 12 , the number of auxiliary steam channels 4 is two, which are distributed on both sides of the width direction of the main steam channel 3. The number of steam switch wires 240 is two, which respectively extend downward through an auxiliary steam channel 4. The steam switch 230 is connected in a loop with the heating element of the liquid heating device and the power supply. The first protruding ribs 110 have 4, and the second protruding ribs 2216 also have 4, and the 4 first protruding ribs 110 are connected in one-to-one correspondence with the 4 second protruding ribs 2216. Among them, the middle two first protruding ribs 110 and the middle two second protruding ribs 2216 enclose the first section main steam channel 310. Between one side of a first protruding rib 110 and the adjacent first protruding rib 110, and between the abutting one second protruding rib 2216 and the adjacent second protruding rib 2216, a first section auxiliary steam channel 410 is enclosed. Between the other side of a first protruding rib 110 and the adjacent first protruding rib 110, and between the abutting one second protruding rib 2216 and the adjacent second protruding rib 2216, the other first section auxiliary steam channel 410 is enclosed. The two first section auxiliary steam channels 410 are distributed on both sides of the width direction of the first section main steam channel 310 and are separated by a shared protruding rib. The number of third protruding ribs 211 is two, and the two third protruding ribs 211 cooperate with the middle two first protruding ribs 110, and the two third protruding ribs 211 and the corresponding two first protruding ribs 110 enclose the second section main steam channel 320. The two first protruding ribs 110 located on both sides abut the side wall of the handle body 210 facing the container body 1, and the corresponding part of the handle body 210 between the two first protruding ribs 110 located on both sides and the middle two first protruding ribs 110 encloses two second section auxiliary steam channels 420.

[0099] Further, as shown in Figure 1 and Figure 2 , the width of at least one of the first section main steam channel 310 and the second section main steam channel 320 gradually increases from top to bottom. It is beneficial for steam to quickly pass through the main steam channel 3, thereby reducing the temperature outside the handle assembly 2.

[0100] Further, in some embodiments, the steam box 220 is inclined to be arranged away from the container body 1, and the top of the steam box 220 is away from the container body 1 relative to the bottom of the steam box 220. Since the steam box 220 directly forms the first section main steam channel 310 and the first section auxiliary steam channel 410 with the side wall of the container body 1, the inclined arrangement of the steam box 220 can increase the top space of the first section main steam channel 310 and the first section auxiliary steam channel 410, and can form a channel that is large at the top and small at the bottom, which is beneficial for steam to pass through.

[0101] As an example, the steam box 220 has an inclination angle ranging from 3° to 30°. The steam is conveniently guided into the main steam passage 3 and the auxiliary steam passage 4, and the steam box 220 occupies a small space and is conveniently arranged in the handle body 210 without interfering with the bend at the upper portion of the handle body 210. For example, the steam box 220 has an inclination angle of 5°, 10°, 14°, or 20°. It should be noted that the inclination angle of the steam box 220 is based on the steam box 220 being vertically arranged along the plumb direction. When the steam box 220 is vertically arranged along the plumb direction, the outer surface of the box wall of the steam box 220 facing the side wall of the container body 1 is taken as a reference surface, and the angle between the outer surface of the box wall of the steam box 220 facing the side wall of the container body 1 after the inclination and the reference surface is the inclination angle of the steam box 220.

[0102] Further, in some embodiments, as shown in Figure 4 、 Figure 6 and Figure 7 , a second blocking rib 2221 extending downward is arranged at the bottom of the side of the steam box 220 away from the side wall of the container body 1, and the second blocking rib 2221 is in abutment with the side wall of the handle body 210 to block the steam from entering the gap between the steam box 220 and the handle body 210. The design of the second blocking rib 2221 can block the steam from directly transferring heat to the handle body 210, thereby reducing the risk of scalding for the user.

[0103] Further, in some embodiments, as shown in Figure 2 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 13 , the interior of the container body 1 includes a containing cavity 120 capable of containing liquid and a mounting cavity 130 located below the containing cavity 120, and the upper portion of the cavity side wall of the containing cavity 120 is provided with an exhaust port 121 in communication with the main steam passage 3; the cavity side wall of the mounting cavity 130 is provided with a first through hole 132 and a second through hole 133, the first through hole 132 is in communication with the main steam passage 3, and the second through hole 133 is in communication with the auxiliary steam passage 4, the steam switch wire 240 extends into the mounting cavity 130 through the second through hole 133 and is electrically connected with the temperature controller 131 in the mounting cavity 130.

[0104] In these embodiments, the container body 1 comprises upper and lower parts: an upper receiving cavity 120 and a lower mounting cavity 130. An exhaust port 121 is provided on the side wall of the receiving cavity 120 to connect the receiving cavity 120 and the main steam channel 3, facilitating the smooth discharge of steam from the receiving cavity 120 into the main steam channel 3. This design is simple and easy to manufacture. After entering the main steam channel 3 through the exhaust port 121, some steam flows along the main steam channel 3 and the first through hole 132 into the mounting cavity 130, and finally exits the container body 1. Other steam flows through the steam box 220, the auxiliary steam channel 4, and the second through hole 133 into the mounting cavity 130, and then exits the container body 1. The steam switch wire 240 is electrically connected to the thermostat 131 in the mounting cavity 130 through the second through hole 133, and connected to the power supply via the thermostat 131. This eliminates the need for additional holes in the container body 1 for the steam switch wire 240 to pass through, ensuring the structural strength of the container body 1, reducing manufacturing steps, and lowering costs.

[0105] In specific applications, such as Figure 2 As shown, when there are two auxiliary steam channels 4, there are also two second through holes 133, which are connected to the auxiliary steam channels 4 one by one.

[0106] In practical applications, when boiling water, the power switch controls the steam switch 230 to be energized, and the heating plate heats the liquid. When the water boils, a large amount of steam is generated. The steam is discharged from the exhaust port 121 of the container body 1 and enters the main steam channel 3. Part of the steam enters the steam box 220, and part of the steam enters the mounting cavity 130 at the bottom of the container body 1 along the main steam channel 3. At this time, the part of the steam that enters the steam box 220 is discharged from the steam outlet 2212 and enters the mounting cavity 130 at the bottom of the container body 1 through the auxiliary steam channel 4. When the temperature sensed by the steam switch 230 reaches the power-off temperature, the steam switch 230 activates and cuts off the power. Subsequently, as the amount of steam in the container 1 decreases, cold air enters the steam box 220 from the main steam channel 3 and the auxiliary steam channel 4, cooling the steam switch 230 and the inside and outside of the channels, causing the steam switch 230 to reset. At the same time, the steam entering from the side cools the steam switch wire 240. When the temperature inside the steam box 220 drops, some of the condensate formed by the steam flows out from the condensate outlet 2213 and enters the main steam channel 3 for discharge.

[0107] In this embodiment, the built-in steam box 220 separates the steam from the conductive wires, thus addressing the risk of electric shock. By designing three steam channels—one main steam channel 3 and two auxiliary steam channels 4—the operation and reset of the steam switch 230 are accelerated, while the external temperature of the steam switch wire 240 is reduced, preventing the plastic from melting due to excessive temperature.

[0108] Furthermore, in some embodiments, the liquid heating device is an electric kettle, a health pot, or a teapot, etc.

[0109] Although the embodiments of the present application have been described in detail above, various modifications and changes can be made to the embodiments of the present application by those skilled in the art without departing from the spirit and scope of the present application. It should be understood that these modifications and changes will still fall within the spirit and scope of the embodiments of the present application as defined by the claims.
