Description

TECHNICAL FIELD

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

[0002] In the related art, the power switch is arranged on the handle, the steam switch is arranged inside the handle, and the 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 passes through the steam switch. The steam switch 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 handle, condensate water generated by steam condensation is likely to appear at the position of the power switch, which affects the user experience. SUMMARY

[0003] Therefore, the utility model aims to provide a handle and a liquid heating device, which can reduce the probability of condensate water generated by steam condensation appearing at the position of the power switch.

[0004] The first aspect of the utility model provides a handle, which comprises: a handle main body; a handle cover arranged on the handle main body, the handle cover having an opening; a power switch movably arranged at the opening; a steam switch movably arranged inside the handle main body; a partition piece, the partition piece being capable of separating the space inside the handle main body into a first space where the power switch is located and a second space where the steam switch is located, the partition piece being provided with a through hole; and a transmission mechanism, a first end of the transmission mechanism being connected with the power switch, and a second end of the transmission mechanism being connected with the steam switch through the through hole; wherein, when the power switch moves to an open position, the power switch can drive the steam switch to open and energize through the transmission mechanism, and when the steam switch is reset and de-energized under the influence of steam, the steam switch can drive the power switch to reset through the transmission mechanism.

[0005] The handle provided by the present aspect of the utility model separates the power switch and the steam switch by arranging a partition piece inside the handle main body, so that the two are not in the same space, which can effectively block the steam flowing into the second space where the steam switch is located from flowing to the power switch, thereby reducing the probability of condensate water generated by steam condensation appearing at the position of the power switch. Moreover, the partition piece is provided with a through hole, and the transmission mechanism is arranged to connect the power switch and the steam switch through the through hole, which does not affect the linkage relationship between the power switch and the steam switch, and ensures that when the power switch is pressed by a user, the steam switch can be driven to open and energize, and when the steam switch is reset and de-energized, the power switch can be driven to reset.

[0006] Further, in some embodiments, the handle has a steam passage inside, the steam passage being used for discharging the steam generated in the container body of the liquid heating device, and the second space is in communication with the steam passage.

[0007] In these embodiments, the steam in the container body of the liquid heating device can be exhausted through the steam channel in the handle, which is conducive to balancing the pressure difference between the inside and outside of the container body. In addition, the second space is in communication with the steam channel, and by default, the first space is not in communication with the steam channel, which can effectively prevent the steam from flowing to the power switch, thereby preventing condensed water from appearing near the power switch or even flowing out of the handle cover.

[0008] Further, in some embodiments, the partition is located in the upper portion of the handle body, the steam channel includes a first sub-steam channel arranged on the side of the partition away from the handle cover and a second sub-steam channel arranged on the side of the handle body away from the handle cover, and the lower end of the first sub-steam channel is in communication with the upper end of the second sub-steam channel.

[0009] In these embodiments, the side of the partition away from the handle cover is directly provided with the first sub-steam channel, and the side of the handle body away from the handle cover is provided with the second sub-steam channel, so that after the steam flows out of the container body, it enters the second sub-steam channel through the first sub-steam channel, which can ensure that the steam flows through one side of the partition and is conducive to the steam flowing through the steam switch. In addition, the steam channel is arranged away from the handle cover, which is not easy to scald the user.

[0010] Further, in some embodiments, the partition is a steam box, the internal space of the steam box forms the second space, the steam switch is arranged in the steam box, and the through hole is arranged on the steam box; the steam box is further provided with a steam inlet, which is used to guide the steam to flow to the steam switch.

[0055] The embodiments of the present application will be described below with reference to the accompanying drawings. Figures 1 to 11 The handle provided by the embodiments of the present application and the liquid heating device using the handle are introduced.

[0056] As shown in Figures 1 to 5 The first aspect of the present application provides a handle, which comprises: a handle body 100; a handle cover 200 arranged on the handle body 100, the handle cover 200 being provided with an opening 210; a power switch 300 movably arranged at the opening 210; a steam switch 400 movably arranged in the handle body 100; a partition 500, the partition 500 being capable of dividing the space in the handle body 100 into a first space 110 where the power switch 300 is located and a second space 120 where the steam switch 400 is located, the partition 500 being provided with a through hole; a transmission mechanism 600, a first end of the transmission mechanism 600 being connected with the power switch 300, and a second end of the transmission mechanism 600 being connected with the steam switch 400 through the through hole; wherein when the power switch 300 moves to an open position, the power switch 300 is capable of driving the steam switch 400 to open the power supply through the transmission mechanism 600, and when the steam switch 400 resets to cut off the power supply under the influence of steam, the steam switch 400 is capable of driving the power switch 300 to reset through the transmission mechanism 600.

[0057] The handle provided in this embodiment, by providing a separator 500 within the handle body 100, separates the power switch 300 and the steam switch 400, preventing them from being in the same space. This effectively blocks steam from flowing into the second space 120 where the steam switch 400 is located from flowing into the power switch 300, reducing the probability of condensation at the power switch 300. Furthermore, the separator 500 has a through hole through which a transmission mechanism 600 connects the power switch 300 and the steam switch 400. This does not affect the linkage between the power switch 300 and the steam switch 400, ensuring that when the power switch 300 is pressed by the user, it activates the steam switch 400, and when the steam switch 400 de-energizes, it resets the power switch 300.

[0058] It should be noted that the size of the through hole is not very large, usually fitting the transmission mechanism 600. Steam does not easily pass through the through hole to flow to the power switch 300, and the separator 500 can still block the steam. Even if a small amount of steam flows into the first space 110 where the power switch 300 is located through the through hole, it will quickly condense and will not condense at the power switch 300 and flow out of the handle.

[0059] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the handle has a steam channel inside, which is used to discharge steam from the container body 700 of the liquid heating device, and the second space 120 is connected to the steam channel.

[0060] In these embodiments, steam within the container 700 of the liquid heating device can be vented through the steam passage in the handle, which helps to balance the pressure difference inside and outside the container 700. Furthermore, by connecting the second space 120 to the steam passage, steam can enter the second space 120 and flow to the steam switch 400 during steam venting, ensuring that the steam switch 400 can be switched on and off according to the steam temperature. Additionally, by default, the first space 110 is not connected to the steam passage, which prevents steam from flowing to the power switch 300, thereby preventing condensation from forming near the power switch 300 or even flowing out of the handle cover 200.

[0061] In practical applications, pressing the power switch 300 activates the steam switch 400 via the transmission mechanism 600, initiating the heating of the liquid. When the liquid in the container 700 reaches its boiling point, a large amount of steam is generated. The steam flows out of the container 700 into the steam channel and then towards the steam switch 400. When the steam temperature reaches the operating temperature of the steam switch 400, the switch resets and disconnects the circuit, stopping the heating of the liquid. The steam then dissipates through the steam channel.

[0062] In one specific embodiment, as shown in Figure 1 、 Figure 2 、 Figure 6 and Figure 10 , the partition 500 is located at the upper part of the handle body 100, the steam passage includes a first sub-steam passage 513 arranged at the side of the partition 500 away from the handle cover 200 and a second sub-steam passage 130 arranged at the side of the handle body 100 away from the handle cover 200, and the lower end of the first sub-steam passage 513 communicates with the upper end of the second sub-steam passage 130.

[0063] In these embodiments, the side of the partition 500 away from the handle cover 200 is directly provided with the first sub-steam passage 513, and the side of the handle body 100 away from the handle cover 200 is provided with the second sub-steam passage 130, so that after the steam flows out of the container body 700, it enters the second sub-steam passage 130 through the first sub-steam passage 513, which can ensure that the steam flows through one side of the partition 500 and is beneficial to the steam flowing through the steam switch 400. In addition, the steam passage is arranged away from the handle cover 200, which is not easy to scald the user.

[0064] As an example, as shown in Figure 6 and Figure 10 , the side of the partition 500 facing the container body 700 (i.e. the side of the partition 500 away from the handle cover 200) is provided with a first sub-steam groove, and the first sub-steam groove forms the first sub-steam passage 513. The side of the handle body 100 facing the container body 700 is provided with a second sub-steam groove, and the second sub-steam groove forms the second sub-steam passage 130. The first sub-steam groove and the second sub-steam groove pass through up and down, and the side facing the container body 700 has a groove opening. In the case where the handle body 100 is arranged on the outer side wall of the container body 700, the groove opening of the side of the first sub-steam groove and the second sub-steam groove facing the container body 700 can be sealed by the outer side wall of the container body 700, so as to realize the sealing of the steam passage.

[0065] Among them, two first ribs 720 can be arranged on the outer side wall of the container body 700 at a position corresponding to the first sub-steam groove, and the two first ribs 720 correspond to the two groove side walls of the first sub-steam groove one by one and abut against each other, forming a sealed first sub-steam passage 513. Two second ribs 730 are arranged on the outer side wall of the container body 700 at a position corresponding to the second sub-steam groove, and the two second ribs 730 correspond to the two groove side walls of the second sub-steam groove one by one and abut against each other, forming a sealed second sub-steam passage 130. Each second rib 730 is integrally formed with the first rib 720 above it, so as to avoid the steam leaking out through the gap between the first sub-steam passage 513 and the second sub-steam passage 130.

[0066] Of course, in another specific embodiment, the steam channel can also be set between the handle body 100 and the handle cover 200, so that the steam in the container body 700 can be discharged from the steam channel between the handle body 100 and the handle cover 200.

[0067] In this configuration, the separator 500 can be positioned approximately horizontally within the handle body 100, forming a third sub-steam channel between the downward-facing side of the separator 500 and the handle body 100, and a fourth sub-steam channel between the handle cover 200 and the handle body 100. The steam channels include the aforementioned third and fourth sub-steam channels. The separator 500 has a first space 110 on the side facing the handle cover 200, vertically separating the power switch 300 and the steam switch 400, thus preventing steam from flowing towards the power switch 300.

[0068] The position of the separator 500 can be adjusted according to the position of the steam channel, as long as the separated second space 120 is connected to the steam channel, while the first space 110 is not connected to the steam channel.

[0069] Regarding the specific structure of the separator 500, in some embodiments, the separator 500 is a separator plate. The side of the separator plate facing away from the power switch 300 has a second space 120 where the steam switch 400 is located, and the side of the separator plate facing the power switch 300 has a first space 110. The separator plate has a simple structure and is easy to process.

[0070] In practical applications, when the steam passage is located between the handle body 100 and the container body 700, the partition plate can be vertically installed inside the handle body 100, with the steam switch 400 and the power switch 300 located on either side of the partition plate in the horizontal direction. When the steam passage is located between the handle body 100 and the handle cover 200, the partition plate can be horizontally placed inside the handle body 100, with the steam switch 400 and the power switch 300 located on either side of the partition plate in the vertical direction.

[0071] Furthermore, in other embodiments, such as Figures 1 to 4 As shown, the separator 500 is a steam box, and the internal space of the steam box forms a second space 120. The steam switch 400 is installed inside the steam box, and the through hole is installed on the steam box. The steam box is also provided with a steam inlet 512 to guide the steam flow to the steam switch 400.

[0072] In these embodiments, the separator 500 serves as a steam box, with the steam switch 400 placed inside. A steam inlet 512 is provided on the steam box, facilitating steam entry while preventing steam from easily flowing out to the location of the power switch 300, thus reducing the likelihood of condensation at the power switch 300. Furthermore, the steam box provides support for the steam switch 400, allowing it to move within the box without interfering with the external structure. During assembly, the steam switch 400 can be installed into the steam box first, followed by the assembly of the steam box itself, enabling integrated assembly and facilitating installation. Confining the steam within the steam box prevents steam leakage and reduces the risk of burns to the user.

[0073] In practical applications, when the steam channel is located between the handle body 100 and the container body 700, the steam box can be vertically installed inside the handle body 100, and a steam inlet 512 is provided on the side wall of the steam box facing the container body 700. When the steam channel is located between the handle body 100 and the handle cover 200, the steam box can be horizontally placed inside the handle body 100, and a steam inlet 512 is provided on the downward-facing wall of the steam box.

[0074] Of course, the steam box can also be installed at an angle, not limited to the above-mentioned installation posture.

[0075] The specific structure and placement of the separator 500 can vary, and all of them satisfy the technical concept of this application in separating the steam switch 400 and the power switch 300. The following detailed explanation uses a steam box as an example to illustrate the separator 500.

[0076] In the case where the separator 500 is a steam box, regarding the connection structure of the power switch 300 and the steam switch 400, further in some embodiments, such as Figures 6 to 11 As shown, the power switch 300 has a first rotating shaft 310 on both sides of the handle body 100 in the width direction. The power switch 300 is rotatably connected to the handle body 100 and / or the handle cover 200 through the first rotating shaft 310. The steam switch 400 has a second rotating shaft 410 on both sides of the handle body 100 in the width direction. Through holes are distributed on both sides of the steam box in the width direction of the handle body 100. Each second rotating shaft 410 extends into the corresponding through hole so that the steam switch 400 can swing in the steam box through the second rotating shaft 410. The first end of the transmission mechanism 600 is connected to the power switch 300, and the second end of the transmission mechanism 600 is connected to the second rotating shaft 410.

[0077] In the embodiments, the power switch 300 is rotatably connected to the handle body 100 or the handle cover 200 through the first rotating shaft 310, and the steam switch 400 is also rotatably arranged in the steam box through the second rotating shaft 410, both of which are rotatable, and are convenient for linkage through the transmission mechanism 600. Moreover, the transmission mechanism 600 is connected to the second rotating shaft 410 extending into the through hole, and the through hole can not only provide connection between the transmission mechanism 600 and the steam switch 400, but also provide support and limiting for the second rotating shaft 410, so that an additional support part for supporting the second rotating shaft 410 is avoided, the structure of the steam box is simplified, and the processing cost is reduced.
