[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-4 The liquid heating device used in this embodiment has a liquid storage container 1, and the liquid storage container 1 has an internal liquid storage space 2, such as... Figure 1 As shown, the liquid storage container 1 can be designed as a cup for easy carrying.
[0030] The liquid heating device has an electric heating element 3 for heating the liquid in the storage container 1. The liquid is heated by the electric heating element 3 so that the user can obtain the required hot water, such as heating water for preparing formula during breastfeeding.
[0031] In this embodiment, the liquid heating device with a screw cap has a venting structure, which includes a cup opening 4 and a protective cap 5.
[0032] The cup opening 4 is connected to the internal liquid storage space 2 of the liquid storage container 1. A first thread 401 is formed on the cup opening 4. The first thread 401 is an external thread or an internal thread.
[0033] The protective cap 5 is used to cover the mouth of the cup 4. The protective cap 5 is formed with a second thread 501 that mates with the first thread 401. The second thread 501 is either an internal thread or an external thread. When the first thread 401 is an external thread, the second thread 501 is an internal thread; when the first thread 401 is an internal thread, the second thread 501 is an external thread.
[0034] The protective cover 5 is the aforementioned screw-on cap, which protects the cup opening 4. The engagement of the first thread 401 and the second thread 501 allows the protective cover 5 to be easily installed and removed.
[0035] When the first thread 401 and the second thread 501 are screwed together, a venting channel 6 is formed between the first thread 401 and the second thread 501 along the spiral path of the thread; when the protective cover 5 is placed on the cup mouth 4, the venting channel 6 connects the vent 402 of the cup mouth 4 with the outside of the protective cover 5.
[0036] When the liquid in the internal storage space 2 is heated to generate steam and pressurize it, the internal gas can be discharged from the venting channel 6 formed by the first thread 401 and the second thread 501 without removing the protective cover 5. The venting structure is easy and simple to prepare, and can effectively prevent hot water from splashing out quickly when venting.
[0037] When the exhaust pressure is high, it also cleans the threaded area. That is, the high-pressure gas will carry out the residue in the venting channel 6, so as to ensure the cleanliness of the threaded area.
[0038] In some embodiments, when the first thread and the second thread are screwed together: there is a venting gap forming a venting channel between the crest of the first thread and the root of the second thread; or there is a venting gap forming a venting channel between the root of the first thread and the crest of the second thread. The preparation of the venting channel is relatively simple; in terms of process modification, it is only necessary to increase the corresponding root or decrease the corresponding crest.
[0039] like Figure 2 , 3 As shown, in some embodiments, the first thread 401 is an external thread provided on the outside of the cup mouth 4, and the second thread 501 is an internal thread provided on the inside of the side seal of the protective cover 5; there is a venting gap 601 between the root 4011 of the first thread and the crest 5011 of the second thread, which constitutes a venting channel 6.
[0040] At the same thread position after the first thread 401 and the second thread 501 are screwed together, the minor diameter d on the first thread 401 corresponding to the root 4011 of the first thread is smaller than the minor diameter D on the second thread 501 corresponding to the crest 5011 of the second thread, so that there is a venting gap 601 forming a venting channel between the root 4011 of the first thread and the crest 5011 of the second thread.
[0041] In some embodiments, the first thread 401 and the second thread 501 each have a thread start point and a thread end point corresponding to the venting channel 6.
[0042] The hot air discharged from the vent 402 at the mouth of the cup can enter the vent 6 from the thread start point 4012 of the first thread or the thread start point 5012 of the second thread, and finally exit from the vent 6 from the thread end point 4013 of the first thread or the thread end point 5013 of the second thread.
[0043] In some embodiments, since the first thread 401 and the second thread 501 are screwed together to different degrees, after the first thread 401 and the second thread 501 are screwed together, the hot air discharged from the outlet 402 of the cup mouth can also enter the venting channel 6 from a point between the thread start point and the thread end point of the first thread or the second thread, and finally exit the venting channel 6 from a point between the thread start point and the thread end point of the first thread or the second thread along the thread path.
[0044] In some embodiments, the first thread 401 and the second thread 501 have the same tooth profile.
[0045] like Figure 1 As shown, in some implementations, the cup opening 4 is arranged vertically, with the vent 402 of the cup opening located at the top; the first thread 401 is an external thread, and the second thread 501 is an internal thread; the top seal of the protective cover 5 and the vent 402 of the cup opening have a buffer space 7 that communicates with the ventilation channel 6.
[0046] The hot air discharged from the cup opening 4 first enters the venting channel 6 from the starting point of the thread above the first thread 401, then travels along the thread path to the ending point of the thread below the first thread 401, thus exiting the venting channel 6, and finally exiting from the gap between the bottom of the side seal of the protective cover 5 and the bottom of the outer side of the cup opening 4.
[0047] On the one hand, when hot air forms water droplets in the ventilation channel 6, the design of discharging from top to bottom makes it easier for the water droplets to be discharged from the ventilation channel 6 (due to its own gravity and the increasing gas pressure during heating). On the other hand, it can effectively prevent backflow when cleaning the threaded position.
[0048] Furthermore, a sealing cap 8 is connected to the inner side of the cup mouth 4. The sealing cap 8 has a vent 801 that communicates with the internal liquid storage space 2 of the liquid heating device. The buffer space 7 communicates with the vent 801.
[0049] In some embodiments, the sealing cap 8 is detachably connected to the cup opening 4, such as the cup opening 4 having internal threads on the inside and the sealing cap 8 having corresponding external threads.
[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
