Description

Technical Field

[0001] This utility model relates to the field of thermostat technology, specifically, a novel water-electricity separation type global water temperature controller. Background Technology

[0002] A thermostat is a device used to control temperature, widely used in homes, industry, and commerce. Its basic function is to maintain a set temperature by adjusting the switching of heating or cooling systems to ensure that the ambient temperature remains within a certain range. With increasing demands for energy conservation and environmental protection, thermostat technology is constantly developing towards greater efficiency, precision, and intelligence, becoming an indispensable part of modern household and industrial equipment.

[0003] Chinese utility model patent CN219625901U discloses a water-electricity separation type full-range water temperature controller, including a shell, a water circulation component at the bottom inner side of the shell, an isolation part at the top of the water circulation component, and a temperature regulating component and a control component at the top of the isolation part. The temperature regulating component includes a temperature regulating part connected to the water circulation component, and the temperature regulating part is connected to the control component. The control component includes a detection part for detecting the temperature of the water circulation component. The control component controls the working power of the temperature regulating component and controls the temperature regulating part to heat up or cool down the water circulation component based on the temperature detected by the detection part. Its advantages are: it can adjust the circulating water volume and working power of the temperature controller in real time, thereby accurately cooling or heating the circulating water under self-circulating water flow conditions, achieving accurate full-range temperature control of the circulating water. Simultaneously, the internal structure of the full-range temperature controller separates water and electricity, preventing water leakage from affecting the electronic components of the full-range temperature controller. However, its shortcomings include: the lack of vibration damping devices causes the main water pump to vibrate significantly and produce considerable noise during operation, affecting the user experience. Furthermore, after prolonged use, the water cooling head may detach from the thermoelectric cooler. Utility Model Content

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.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Special Note: This utility model is a further improvement based on the application number CN 202320127821.6 entitled "A Water-Electricity Separation Type Water Body Global Temperature Controller" (hereinafter referred to as "Basic Document"). The following only describes the improved parts. The rest of the unmentioned parts are consistent with the layout of the Basic Document. Those skilled in the art can easily understand the working principle of this utility model based on the Basic Document, so it will not be described in detail here.

[0033] Example 1:

[0034] This embodiment provides a novel water-electricity separation type global water temperature controller, specifically as follows: Figures 1-4 , Figure 6 As shown, the device includes a housing 1 with a built-in power supply. A water circulation assembly 2 is mounted on the bottom of the housing 1. An isolation section 3 is provided on the top of the water circulation assembly 2. A temperature regulating assembly 4 and a control assembly 5 are provided on the top of the isolation section 3. The temperature regulating assembly 4 includes a temperature regulating part extending below the isolation section 3 and connected to the water circulation assembly 2. The temperature regulating part is connected to the control assembly 5. The control assembly 5 includes a detection part extending below the isolation section 3 for detecting the temperature of the water circulation assembly 2. The control assembly 5 controls the operating power of the temperature regulating assembly 4 and the temperature regulating part based on the temperature of the water circulation assembly 2 detected by the detection part. The water circulation component 2 heats up or cools down the water. The water circulation component 2 includes a water pump component 21, a water cooling head 22, a diaphragm pump 23, and a one-way valve 24. The arrangement of the diaphragm pump 23 and the one-way valve 24 is the same as in the basic document. The water pump component 21 includes a main water pump 213. The inlet of the main water pump 213 is connected to the inlet on the outer casing 1, and the outlet of the main water pump 213 is connected to the water cooling head 22. The outlet of the water cooling head 22 is connected to the outlet on the outer casing 1. The water pump component 21 also includes a shock absorber to improve the operational stability of the main water pump 213.

[0035] By incorporating a vibration damping unit, the vibration amplitude of the main water pump 213 is reduced during operation, thereby minimizing the shaking of the outer casing 1; at the same time, noise generated by vibration is reduced, improving user comfort; and the operational stability of the main water pump 213 is also improved.

[0036] Example 2:

[0037] This embodiment further expands the shock-absorbing part based on the above embodiment, specifically as follows: Figures 6-9 As shown, the shock-absorbing part includes a suspension plate, a screw 214, and a shock-absorbing pad 215. The screw 214 is provided with a pressing step surface 217. The suspension plate and the main water pump 213 are both provided with slots for locking the shock-absorbing pad 215. The screw 214 is threadedly connected to the isolation part 3, and the pressing step surface 217 is used to press the suspension plate.

[0038] During assembly, the shock-absorbing pads 215 are sequentially inserted into the slots of the suspension plate and the main water pump 213, with the insertion direction of the shock-absorbing pads 215 on the suspension plate and the main water pump 213 being perpendicular to each other to prevent the shock-absorbing pads 215 from falling off. Then, screws 214 are passed through the shock-absorbing pads 215 and the suspension plate, and threadedly connected to the isolation part 3. At this point, the pressing step surface 217 presses the suspension plate onto the isolation part 3, thus installing the main water pump 213 while simultaneously using the shock-absorbing pads 215 for vibration damping. Installing the main water pump 213 on the isolation part 3, compared to installing the main water pump 213 on the outer casing 1, further improves the vibration damping effect.

[0039] The suspension plate includes a first suspension plate unit 211 and a second suspension plate unit 212. The first suspension plate unit 211 is provided with a through hole for the screw 214 to pass through, and the second suspension plate unit 212 is provided with a slot for the shock-absorbing pad 215 to be embedded. The first suspension plate unit 211 and the second suspension plate unit 212 are fixedly connected.

[0040] The suspension disc is divided into a first suspension disc unit 211 and a second suspension disc unit 212. During processing, only the first suspension disc unit 211 and the second suspension disc unit 212 need to be processed separately. The main processing technology is milling, followed by assembly, which can greatly reduce the difficulty of the processing technology.

[0041] The shock-absorbing pad 215 has an annular groove 216 located between the main water pump 213 and the suspension plate. By setting the annular groove 216, the two ends of the shock-absorbing pad 215 have sufficient strength, while the middle part has sufficient plasticity, making it easy to absorb shock and deform, thereby further improving the shock absorption capacity.

[0042] A gap is reserved between the head of the screw 214 and the end of the shock-absorbing pad 215. By setting the reserved gap, when the main water pump 213 vibrates, the shock-absorbing pad 215 can continue to move downward, and the head of the screw 214 will not block the movement of the shock-absorbing pad 215, thus ensuring the shock absorption effect.

[0043] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0044] Example 3:

[0045] This embodiment further extends the above embodiment, specifically as follows: Figures 3-5As shown, the water-cooled mounting bracket 25 is mounted on the isolation section 3 via spring studs 28, and the water-cooling head 22 is mounted on the water-cooled mounting bracket 25. There are two water-cooling heads 22 and two water-cooled mounting brackets 25. The temperature control component 4 also includes a cooling fan 41 and a radiator 42. The radiators 42 are symmetrically arranged on both sides of the cooling fan 41, with one radiator 42 corresponding to the air inlet on the outer casing 1 and the other radiator 42 corresponding to the air outlet on the outer casing 1. The heat exchange tubes of the radiator 42 pass downward through the isolation section 3 and contact the temperature control section for heat exchange. The temperature control section includes two thermoelectric coolers 43, which are disposed between the radiator 42 and the water-cooling head 22. The thermoelectric coolers 43 are electrically connected to the control component 5.

[0046] During after-sales service, the applicant discovered that the heat sink 42 and the thermoelectric cooler 43 experienced adhesive separation and detachment after prolonged operation. Further investigation revealed that due to the unidirectional airflow of the cooling fan 41, one side of the heat sink 42 was exposed to the airflow first, while the airflow temperature on the other side had already changed by the time it reached the other side. Furthermore, the water flowing from the water-cooling head 22 first exchanged heat with one thermoelectric cooler 43, and then the water temperature changed again when exchanging heat with the other thermoelectric cooler 43. This resulted in subtle differences in the operating environment of the two thermoelectric coolers 43, leading to inconsistent thermal expansion and contraction on both sides. When their volume changed, the water-cooling mounting bracket 25 would spring back... Slight longitudinal movement of the spring stud 28, due to inconsistent thermal expansion and contraction, causes the water cooling head 22 to be subjected to tilting force, resulting in stress accumulation on the water cooling head 22, which may eventually lead to the detachment of the thermoelectric cooler 43 and the heat sink 42. Therefore, by replacing the heat exchange between the two thermoelectric coolers 43 by one water cooling head 22 in the basic document with two independent water cooling heads 22 that exchange heat between individual thermoelectric coolers 43, the problem of stress accumulation on the water cooling head 22 can be solved. Even if there are slight differences in the operating environment of the two thermoelectric coolers 43, the thermal expansion and contraction on both sides are independent, avoiding the risk of the heat sink 42 and the thermoelectric cooler 43 potentially detaching.

[0047] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0048] Example 4:

[0049] This embodiment further extends the above embodiment, specifically as follows: Figure 10As shown, a flow meter 26 is provided between the main water pump 213 and the water cooling head 22, and a temperature sensor 27 is provided between the flow meter 26 and the water cooling head 22. The flow meter 26 includes a housing and a detection element. The housing includes a main housing 261, an encapsulation housing 262, and a sealing gasket 263. The sealing gasket 263 is disposed between the main housing 261 and the encapsulation housing 262. The main housing 261 and the encapsulation housing 262 are threadedly connected.

[0050] Since this thermostat is mainly used in environments such as aquariums, the applicant discovered during after-sales service that the flow meter 26 would absorb impurities such as sand, algae, or feces, resulting in a decrease in accuracy. However, since the flow meter 26 in the basic documentation is a single piece, it cannot be repaired and can only be replaced, leading to higher maintenance costs for users. Therefore, this improvement designs the housing of the flow meter 26 to be detachable, facilitating future maintenance work and reducing maintenance costs for users.

[0051] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0052] Example 5:

[0053] This embodiment is a further extension of the above embodiment. Specifically, as shown in Figure 3, an auxiliary circuit board 6 is installed on the isolation part 3. The auxiliary circuit board 6 is electrically connected to the control component 5. The control component 5 is electrically connected to the main water pump 213, the semiconductor cooling chip 43, the cooling fan 41, and the flow meter 26.

[0054] By setting up the auxiliary circuit board 6, the isolation part 3 can be inserted into the auxiliary circuit board 6. At the same time, the auxiliary circuit board 6 can be connected to the relevant electrical equipment through wires at the point closest to it, thereby reducing the length of the wire arrangement, preventing several wires from crossing and getting mixed together, making wire management more convenient during assembly and maintenance, and reducing the difficulty of subsequent maintenance.

[0055] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0056] Example 6:

[0057] This embodiment further extends the above embodiment, specifically as follows: Figure 2 As shown, the outer casing 1 includes a base 101 and a protective shell 102. The protective shell 102 is equipped with a removable plug 103 and a fuse 104. The plug 103 allows the thermostat to seal the inlet and outlet of the outer casing 1 when not in use, preventing foreign objects from entering and causing blockages. The fuse 104 ensures that it will melt when the thermostat short-circuits; during maintenance, only the fuse 104 needs to be removed and replaced without disassembling the outer casing 1.

[0058] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
