Description

Technical Field

[0001] This application relates to the field of water bath technology, and more specifically to a water bath that prevents dry burning. Background Technology

[0002] A water bath is a commonly used experimental auxiliary testing device, mainly used for distillation and warm soaking of chemicals or biological products, and can also be used for constant temperature heating and other temperature tests.

[0003] Patent document (CN205269708U) discloses a water bath with anti-dry-burning features, including a linkage device and a contact body. The contact body has two spaced-apart contact posts. When the heating liquid level rises, the linkage device rises longitudinally until the contact body and both contact posts are in contact, forming a conductive structure and connecting the heating circuit. Conversely, when the heating liquid level falls, the linkage device descends longitudinally until the contact body and both contact posts separate, forming a disconnect structure and cutting off the heating circuit, thus controlling the heating circuit. However, when the water level in the water bath reaches the warning line, and the heating circuit is disconnected by the longitudinal descent of the linkage device, if the experimental solution requires continuous heating for a predetermined time, and the aforementioned structure disconnects the heating circuit without any warning device for adding water, if the experimenter does not add liquid in time, the temperature of the heating liquid covering the bottom of the experimental solution bottle will gradually decrease, deviating from the original test conditions.

[0004] Therefore, there is a need for an interference-resistant water bath that can continuously disconnect the heating circuit when the water reaches the warning level, issue timely warnings to add liquid, and automatically replenish a portion of the liquid into the water bath. Summary of the Invention

[0005] The main objective of this application is to provide a water bath pot with anti-dry-burning function, comprising a pot body and a power supply. The pot body has a water storage cavity, and a heating element is disposed within the water storage cavity. The heating element is electrically connected to the power supply. The water storage cavity contains water. The pot body has a buoy cavity, a lifting channel, and an inclined channel. The buoy cavity is located below and communicates with the lifting channel. One end of the inclined channel communicates with the lowest point of the lifting channel, and the other end communicates with the outside. The buoy cavity is also communicated with the water storage cavity. The anti-dry-burning water bath pot further includes a floating component, a buzzer, and a rotating component. The floating component includes a floating element, a raising rod, and a ball. The floating element is movable within the buoy cavity according to the water level in the water storage cavity. The end of the raising rod facing away from the floating element extends into the lifting channel. The ball is placed on the raising rod. The buzzer is mounted on the pot body. The rotating component is made of insulating material and is rotatably mounted on the pot body. One side of the rotating component has an extension end that extends into the inclined channel. Several conductive plates are embedded on one side of the rotating component. Two sets of energized plates are also provided on the pot body. Both sets of energized plates are located at the end of the rotating component away from the lifting channel. Each set of energized plates includes two spaced-apart contact plates. The two contact plates on one set of energized plates are electrically connected to one end of the power supply and one end of the buzzer, respectively. The other end of the power supply is connected in series with the other end of the buzzer. When the water level in the water storage chamber reaches the warning line, the ball falls into the inclined channel and impacts the rotating component, causing the conductive plates on the rotating component to conduct with the corresponding contact plates, thus making the buzzer emit a warning sound. Compared with the prior art, this method has the advantages of not disconnecting the heating circuit when the warning water level is reached and being able to issue a timely warning to remind the user to add liquid.

[0006] Another objective of this application is to provide a water bath with anti-dry-boil function, wherein the water bath further includes a spare water tank, which is installed on the bath body and has a water outlet. A normally closed shut-off valve is provided on the water outlet. Two contacts on another set of energized plates are electrically connected to one end of the power supply and one end of the normally closed shut-off valve, respectively.

Both sets of energized plates are located at the end of the rotating component opposite to the lifting channel. Each set of energized plates includes two spaced-apart contact plates. The two contact plates on one set of energized plates are electrically connected to one end of the power supply and one end of the buzzer, respectively, and the other end of the power supply is connected in series with the other end of the buzzer.

[0014] In one or more embodiments of this application, the anti-dry-boil water bath further includes a ball seat, which is disposed at one end of the inclined channel away from the lifting channel and is fixedly connected to the pot body. The ball seat includes a cavity, and one side of the cavity has a notch.

[0015] In one or more embodiments of this application, the inclined channel has an opening on one side, the pot body has a groove and a rotating hole, the rotating hole communicates with the groove, the groove communicates with the opening, the rotating member is rotatably installed in the rotating hole, the extension end passes through the opening and extends into the inclined channel, and when the rotating member rotates a predetermined angle, the extension end disengages from the inclined channel and extends into the groove.

[0024] The terms and words used in the following specification and claims are not limited to their literal meaning, but are used solely by the inventors to enable a clear and consistent understanding of this application. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this application is provided for illustrative purposes only and not for the purpose of limiting the application as defined in the appended claims and their equivalents.

The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0028] Indicative anti-dry-boil water bath, for reference. Figures 1 to 5 According to a preferred embodiment of the present invention, a water bath pot designed to prevent dry burning is provided, such as... Figure 1As shown, it includes a pot body 10 and a power supply 20. The pot body 10 has a water storage cavity 101. A heating element 1011 is provided in the water storage cavity 101. The heating element 1011 is electrically connected to the power supply 20. Water is provided in the water storage cavity 101.

[0029] It should be noted that before the experiment, the laboratory personnel first fill the water storage chamber 101 with water to an initial high point, and then energize the heating element 1011. The heating element 1011 generates heat, raising the water temperature in the water storage chamber 101 to the experimental temperature range. Subsequently, the laboratory personnel place the test bottle containing the solution to be tested into the water storage chamber 101. It should be pointed out that at this time, the water level in the water storage chamber 101 is much higher than the height of the solution to be tested in the test bottle. It should also be noted that the warning water level is also higher than the height of the solution to be tested in the test bottle, and the warning water level submerges the heating element 1011. In addition, the water in the water storage chamber 101 gradually evaporates and the water level decreases over time. Since the heating element 1011 is a mature technology and widely used in the market, the specific structure of the heating element 1011 will not be described in detail here. The heating element 1011 includes, but is not limited to, the electric heating element disclosed in the patent document (CN221464037U).

[0030] Furthermore, to prevent the water level in the water storage chamber 101 from falling below the warning level and causing the heating element 1011 to partially dry-burn, the anti-dry-burn water bath also includes a floating component 30 and a buzzer 40, with the buzzer 40 mounted on the pot body 10.

[0031] It should be noted that the floating component 30 rises or falls with the water level in the water storage chamber 101. When the water level in the water storage chamber 101 drops to the warning position, the buzzer 40 is powered on and sounds to remind the experimenters to add water in time.

[0032] Specifically, to achieve the above technical objectives, such as Figure 1 As shown, the pot body 10 is provided with a buoy cavity 102, a lifting channel 103, and an inclined channel 104. The buoy cavity 102 is located below and communicates with the lifting channel 103. One end of the inclined channel 104 communicates with the lowest point of the lifting channel 103, and the other end of the inclined channel 104 communicates with the outside. The buoy cavity 102 is also connected to the water storage cavity 101. Additionally, as... Figure 1As shown, the floating assembly 30 includes a floating element 301, a booster rod 302, and a ball 303. The floating element 301 is vertically and retractably positioned within the buoy cavity 102 according to the water level in the water storage cavity 101. One end of the booster rod 302, away from the floating element 301, extends into the lifting channel 103. The ball 303 is placed on the booster rod 302. Additionally, as... Figure 2 and Figure 3 As shown, the anti-dry-boil water bath also includes a rotating component 50. The rotating component 50 is made of insulating material and is rotatably mounted on the pot body 10. One side of the rotating component 50 has an extension end 501 that extends into the inclined channel 104. Several conductive plates 502 are embedded on one side of the rotating component 50. Two sets of energized plate groups are also provided on the pot body 10. Both sets of energized plate groups are located at the end of the rotating component 50 away from the lifting channel 103. Each set of energized plate groups includes two spaced-apart contact plates 503. The two contact plates 503 on one set of energized plate groups are electrically connected to one end of the power supply 20 and one end of the buzzer 40, respectively, and the other end of the power supply 20 is connected in series with the other end of the buzzer 40.

[0033] It should be noted that by setting the buoy cavity 102, the floating component 301 can move upward or downward along the height direction of the buoy cavity 102. By setting the lifting channel 103, the ball 303 can move upward or downward along the height direction of the lifting channel 103. When the water level in the water storage cavity 101 is at the initial high point, the floating component 301 is located at the high position of the buoy cavity 102, and the ball 303 is pushed to a position where the lifting channel 103 is higher than the tilting channel 104. When the water level in the water storage cavity 101 drops to the warning position, the ball 303 moves downward to a position level with the tilting channel 104, and the highest point of the raising rod 302 is level with the edge of the inner hole at one end of the tilting channel 104. One end of the channel 104 extends into the lifting channel 103 and is arranged at an angle. It should be noted that the inclined channel 104 is formed by inserting a tube into the corresponding hole in the pot body 10. The ball 303 will roll down the inclined channel 104 and contact the extension end 501 during its rolling, causing the rotating member 50 to rotate at a predetermined angle. Simultaneously, the conductive plate 502 on the rotating member 50 contacts the two contact plates 503 on the corresponding energized plate group. The connection circuit between the power supply 20 and the buzzer 40 forms a closed loop, energizing the buzzer 40 and emitting a sound to alert the experimenter to add water to the water storage chamber 101. After passing through the extension end 501, the ball 303 will be discharged from the other end of the inclined channel 104. It is evident that, compared to the prior art, this application has the advantages of not disconnecting the heating circuit when the warning water level is reached and being able to promptly issue a warning to add liquid.

[0034] Furthermore, since there is a time blind spot between hearing the warning sound and manually adding water, and there may also be situations where laboratory personnel briefly leave the laboratory for any reason, to prevent the heating element 1011 from being powered off and the water level in the water storage chamber 101 from reaching the warning line and continuing to drop over time, potentially leading to dry burning, as follows... Figure 1 As shown, the anti-dry-boil water bath also includes a spare water tank 60, which is installed on the pot body 10. The spare water tank 60 has a water outlet 601, and a normally closed shut-off valve 602 is provided on the water outlet 601. Two contacts 503 on another set of energized contacts are electrically connected to one end of the power supply 20 and one end of the normally closed shut-off valve 602, respectively, and the other end of the power supply 20 is connected in series with the other end of the normally closed shut-off valve 602.

[0035] It should be noted that the normally closed shut-off valve 602 no longer closes the outlet 601 after being energized. The water in the spare water tank 60 can flow along the outlet 601 into the water storage chamber 101 and replenish the water storage chamber 101 with some water, effectively preventing the heating element 1011 from dry burning due to the water level dropping below the warning position.

[0036] It should also be noted that by setting two sets of energized plates on the rotating member 50, when the rotating member 50 rotates a predetermined angle under the impact of the ball 303, one set of energized plates causes the buzzer 40 and the power supply 20 to form a closed circuit, and the other set of energized plates causes the normally closed shut-off valve 602 and the power supply 20 to form a closed circuit. This allows the normally closed shut-off valve 602 to open and replenish water to the water storage chamber 101 after the water level in the storage chamber 101 reaches the warning position. Compared to existing technologies, this has the advantage of automatically replenishing a portion of the liquid in the water bath simultaneously, effectively avoiding the risk of the heating element 1011 burning dry if the experimenter fails to add water in time. It should be added that, referring to... Figure 4 The normally closed shut-off valve 602 and the buzzer 40 can be considered to be connected in parallel and then connected to the power supply 20. In addition, since the normally closed shut-off valve 602 is a mature technology and is widely used in the market, the specific structure of the normally closed shut-off valve 602 will not be described in detail here. The normally closed shut-off valve 602 includes, but is not limited to, the electrically controlled shut-off valve disclosed in the patent document (CN201568390U).

[0037] Furthermore, such as Figure 3 As shown, one end of the rotating member 50 extends outside the pot body 10, and a piece 504 is provided at the end of the rotating member 50 extending outside the pot body 10, one side of the piece 504 having a color.

[0038] It should be noted that in this embodiment, one side of the sheet 504 is red. Additionally, when the water level in the water storage chamber 101 is at its initial high point, the sheet 504 is vertically arranged. When the rotating member 50 rotates at a predetermined angle and energizes the buzzer 40, the sheet 504 is tilted or horizontal, with the red side facing upwards. Furthermore, when the experimenter pours water into the water storage chamber 101, and then holds the sheet 504 and rotates it in the opposite direction until it cannot rotate further, the rotating member 50 returns to its initial position, and the sidewall of the rotating member 50 (i.e., the insulating part, because the entire rotating member 50 is made of insulating material) is positioned between the two contact pieces 503, disconnecting the circuit between the buzzer 40 and the power supply 20. The normally closed shut-off valve 602 is also disconnected from the power supply 20, causing the buzzer 40 to stop emitting sound, and the normally closed shut-off valve 602 to be de-energized and block the water outlet 601 again.

[0039] Furthermore, to collect the spheres 303 that roll out of the inclined channel 104, so that after replenishing water in the water storage chamber 101, the experimenter can place the spheres 303 back into the lifting channel 103 and position them at the top of the raising rod 302, as follows: Figure 1 and Figure 5 As shown, the anti-dry-boil water bath also includes a ball seat 70, which is located at one end of the inclined channel 104 away from the lifting channel 103 and is fixedly connected to the pot body 10. The ball seat 70 includes a cavity 701, and one side of the cavity 701 has a notch 702.

[0040] It should be noted that after the ball 303 rolls out of the inclined channel 104, it falls into the cavity 701 of the ball seat 70. Furthermore, the notch 702 is provided to facilitate the removal of the ball 303 from the cavity 701.

[0041] Furthermore, in the embodiments of this application, such as Figure 2 As shown, the inclined channel 104 has an opening 1041 on one side, the pot body 10 has a groove 105 and a rotating hole 106, the rotating hole 106 communicates with the groove 105, the groove 105 communicates with the opening 1041, the rotating member 50 is rotatably installed in the rotating hole 106, the extension end 501 passes through the opening 1041 and extends into the inclined channel 104, when the rotating member 50 rotates a predetermined angle, the extension end 501 disengages from the inclined channel 104 and extends into the groove 105.

[0042] In addition, to ensure that the extension end 501 can be fixed at a certain angle after rotating at a predetermined angle, and to ensure that the conductive sheet 502 contacts the corresponding two contact sheets 503, such as Figure 2 As shown, a first magnet 5011 is embedded on one side of the extension end 501, and a second magnet 1051 is embedded in the groove 105. When the extension end 501 extends into the groove 105, the first magnet 5011 and the second magnet 1051 attract each other.

[0043] In summary, the anti-dry-burning water bath described in the embodiments of this application is explained, which provides advantages such as continuous heating circuit when the warning water level is reached, timely warning reminder to add liquid, and automatic replenishment of some liquid into the water bath.

[0044] It is worth mentioning that, in this embodiment, the anti-dry-boil water bath has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the anti-dry-boil water bath provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
