Description

TECHNICAL FIELD

[0001] The utility model relates to liquid heating equipment technical field, concretely is a detachable liquid heating equipment. BACKGROUND

[0002] Liquid heater has a wide range of applications in daily life, which provides convenience for people to heat various liquids. The traditional liquid heater usually adopts a fixed connection mode, and the heating part and the power supply part are difficult to separate. This design has some obvious shortcomings.

[0003] Firstly, the integral liquid heater is large in size, which is inconvenient to store and carry. Whether in family use or in outdoor travel and other scenarios, it occupies a large space, which brings inconvenience to users. Secondly, the fixed connection makes cleaning difficult. Since the heating part and the power supply part cannot be separated, extra care is needed during cleaning to avoid damaging electrical components, which increases the difficulty and risk of cleaning. Thirdly, the power supply mode of the traditional liquid heater is relatively single, generally relying on fixed power sockets, lacking flexibility, and cannot be used in places without power supply.

[0004] Taking a milk warmer (milk warmer cup) as an example, the traditional milk warmer is mostly designed in one piece. For families with babies, this design will bring many troubles in actual use. For example, when going out, the one-piece milk warmer is inconvenient to carry, and may not meet the needs of warming milk for babies anytime and anywhere. Moreover, the milk warmer often needs to be cleaned during use, and if it is designed in one piece, the power supply part may be wet during cleaning, which may cause short circuit and other safety problems. In addition, the traditional milk warmer can only be used in places with fixed power supply, limiting its use scenarios.

[0005] In view of this, the prior art proposes a detachable liquid heater, however, most of the current detachable liquid heaters adopt a single contact or probe to meet the power supply demand in the electrical connection between the base and the main body. This design has many drawbacks. On the one hand, the single contact or probe connection mode is relatively insufficient in stability and reliability. During use, it is easy to have poor contact due to slight vibration, collision or wear after long-term use, thereby affecting the normal work of the liquid heating equipment. For example, during daily use, if the heating equipment is moved accidentally, it may cause the connection of the single contact or probe to be interrupted, causing the heating process to stop suddenly. On the other hand, the power supply capacity of the single contact or probe is limited. For some liquid heating equipment with high power, the single contact or probe may not be able to provide enough stable current, resulting in slow heating speed and unsatisfactory heating effect. For example, when a large amount of liquid needs to be heated quickly, the insufficient power supply of the single contact or probe may prolong the heating time, bringing inconvenience to users.

[0006] Therefore, it is necessary to provide an improved technical solution to solve the above problems. Utility model content

[0007] The utility model discloses to overcome above-mentioned situation shortage, aim at providing a kind of technical scheme to solve above-mentioned problem.

[0008] A detachable liquid heating device, comprising a liquid heating device main body and a power supply base detachably connected to the liquid heating device main body, the power supply base is provided with a power supply end corresponding to one end of the liquid heating device main body, the liquid heating device main body is provided with an electrical connection end corresponding to one end of the power supply base, the power supply end comprises a conductive point groove and a conductive ring groove, the conductive ring groove surrounds the conductive point groove and is concentric with it, the electrical connection end comprises at least two positive contacts arranged oppositely and a negative contact located on the perpendicular bisector of the line connecting the at least two positive contacts, wherein the positive contacts correspond to the conductive ring groove, and the negative contact corresponds to the conductive point groove.

[0009] As a further aspect of the utility model: when the power supply base and the liquid heating device main body are connected, the positive contacts and the conductive ring grooves are in close contact, and the negative contacts and the conductive point grooves are in close contact.

[0010] As a further aspect of the utility model: the positive contacts and the negative contacts are both of elastic structure.

[0011] As a further aspect of the utility model: the two positive contacts correspond to the conductive ring groove, and the two positive contacts are symmetrically distributed on both sides of the conductive ring groove.

[0012] As a further aspect of the utility model: the mating surfaces of the positive contacts and the conductive ring grooves, and the mating surfaces of the negative contacts and the conductive point grooves are all arc surfaces.

[0013] As a further aspect of the utility model: the power supply base is provided with a power supply module, and the conductive point groove and the conductive ring groove are electrically connected with the power supply module.

[0014] The liquid heating device main body is provided with a control unit and a heating module, and the heating module, the positive contacts and the negative contacts are electrically connected with the control unit.

[0015] As a further aspect of the utility model: the connection mode of the power supply base and the liquid heating device main body includes clamping, magnetic attraction, knob type buckle connection or threaded connection.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] 1) The liquid heating device main body and the power supply base are detachable, which can be stored separately when not in use, reducing the occupied space and facilitating carrying. Whether used at home or on a trip, it can easily meet the needs of users. For example, a baby's family can separate the baby bottle main body and the power supply base when going out, and warm milk for the baby anytime, anywhere. Moreover, the separated design allows the liquid heating device main body to be cleaned separately, without worrying about damaging the power supply part, making cleaning more convenient, safe, reducing the difficulty and risk of cleaning;

[0018] 2) Multiple positive contact points and special conductive ring grooves and conductive point groove designs are used. Compared with single contact or probe connection methods, the stability and reliability of the connection are greatly improved. Even after being subjected to slight vibration, impact or long-term use, it is not easy to have a poor contact condition, ensuring the normal work of the liquid heating device. At the same time, the design of multiple positive contact points increases the current transmission capacity, which can provide sufficient stable current for liquid heating devices with high power. For the case of needing to quickly heat a large amount of liquid, the heating time can be shortened, the heating effect can be improved, and users can have a better use experience;

[0019] 3) The shunt design of the two positive contact points and the parallel circuit formed with the negative contact point reduces the current intensity carried by a single contact point and reduces the safety risks of overheating and short circuit caused by excessive current. Even in unexpected situations, such as a contact point being hit by external force or having a poor contact, other contacts can still maintain part of the function of the device, providing a certain safety guarantee for users.

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] Please refer to Figures 1-4 In the embodiments of the utility model, a detachable liquid heating equipment includes a liquid heating equipment main body 1 and a power supply base 2 detachably connected to the liquid heating equipment main body 1. The power supply base 2 is provided with a power supply end 3 corresponding to one end of the liquid heating equipment main body 1. The liquid heating equipment main body 1 is provided with a power connection end 4 corresponding to one end of the power supply base 2. The power supply end 3 includes a conductive point groove 5 and a conductive ring groove 6. The conductive ring groove 6 surrounds the conductive point groove 5 and is concentric with the conductive point groove 5. The power connection end 4 includes at least two positive contacts 7 arranged oppositely and a negative contact 8 located on the perpendicular bisector of the line connecting the at least two positive contacts 7. The positive contact 7 corresponds to the conductive ring groove 6, and the negative contact 8 corresponds to the conductive point groove 5.

[0030] In the technical scheme of the utility model, the liquid heating equipment main body 1 and the power supply base 2 are detachably connected. This design fully considers the use requirements of users in different scenarios. For example, in a home environment, the equipment can be stably placed on a desktop for use. When going out or needing to use the equipment on the go, the liquid heating equipment main body 1 and the power supply base 2 can be easily separated, which facilitates carrying and storage and greatly improves the portability of the equipment. The separated structure also brings convenience for cleaning and maintenance of the equipment. Since the liquid heating equipment main body 1 and the power supply base 2 can be separated, the power supply base 2 can be avoided when cleaning the liquid heating equipment main body 1, which reduces the risk of damaging electrical components due to improper cleaning. At the same time, it is also convenient to individually maintain and overhaul each part of the equipment, thereby prolonging the service life of the equipment.

[0031] The power supply end 3 of the power supply base 2 is provided with a conductive point groove 5 and a concentric conductive ring groove 6, the design of the conductive ring groove 6 increases the contact area with the positive contact 7, improves the stability and efficiency of current transmission, and the conductive point groove 5 provides an accurate connection position for the negative contact 8, ensuring the integrity of the current loop; The power connection end 4 of the liquid heating device main body 1 is provided with at least two opposite positive contacts 7 and a negative contact 8 located on the perpendicular bisector of the positive contact 7, which fully considers the uniform distribution and stability of the current, and the design of multiple positive contacts 7 not only increases the current transmission capacity, but also can ensure a certain current transmission through other contacts in the case of poor contact of part of the contacts, improving the reliability of the device;

[0032] Specifically, the two positive contacts 7 act as shunt, when the current flows from the conductive ring groove 6 of the power supply base 2 into the two positive contacts 7 of the liquid heating device main body 1, the current is divided into two paths, respectively through different paths to the heating module and other loads, at the same time with the negative contact 8 to form a parallel circuit, this design makes the current have multiple paths to choose from in the transmission process, increases the stability and reliability of current transmission, when a slight fault or resistance increase occurs in a certain path, other paths can still ensure a certain current transmission, reducing the risk of device failure due to single point failure, in addition, the characteristics of the parallel circuit also make the voltage between the contacts relatively stable, reducing the damage to the device caused by voltage fluctuations;

[0033] Among them, if the device needs, it can be set to four positive contacts 7, two positive contacts 7 correspond to one conductive ring groove 6;

[0034] In summary, the liquid heating device main body 1 and the power supply base 2 can be detached, and can be stored separately when not in use, reducing the occupied space and facilitating carrying, whether for home use or travel, it can easily meet the needs of users, taking the milk warmer as an example, families with babies can separate the milk cup main body and the power supply base 2 when going out, and can warm milk for the baby anytime and anywhere, the separated design makes the liquid heating device main body 1 can be cleaned separately, without worrying about damaging the power supply part, cleaning is more convenient and safe, reducing the difficulty and risk of cleaning;

[0035] The design of multiple positive contact points 7 and special conductive ring grooves 6 and conductive point grooves 5 greatly improves the stability and reliability of the connection compared to the connection mode of a single contact or probe, and even after being subjected to slight vibration, collision or long-term use, it is not easy to appear the situation of poor contact, ensures the normal work of the liquid heating equipment, at the same time, the design of multiple positive contact points 7 increases the current transmission capacity, can provide sufficient stable current for the liquid heating equipment with large power, can shorten the heating time and improve the heating effect for the case of needing to quickly heat a large amount of liquid, and bring better use experience for the user.

[0036] The shunt design of the two positive contact points 7 and the parallel circuit formed with the negative contact point 8 reduces the current intensity borne by a single contact point and reduces the safety risks such as overheating and short circuit caused by excessive current, even in accidental situations, such as a contact point being hit by external force or appearing poor contact, other contact points can still maintain part of the function of the equipment, providing a certain safety guarantee for the user.

[0037] In the embodiment of the utility model, when the power supply base 2 and the liquid heating equipment main body 1 are connected, the positive contact point 7 and the conductive ring groove 6 are in close contact, and the negative contact point 8 and the conductive point groove 5 are in close contact.

[0038] Through the design of close contact, the positive contact point 7 and the conductive ring groove 6, the negative contact point 8 and the conductive point groove 5 can form stable and low-resistance connection, which can ensure that the current can be smoothly transmitted from the power supply base 2 to the liquid heating equipment main body 1, and provide the required power for the heating module and other loads, and ensure the normal operation of the equipment; in the detachable connection structure, the firmness of mechanical connection directly affects the stability of electrical connection, when the positive contact point 7 and the conductive ring groove 6, the negative contact point 8 and the conductive point groove 5 are in close contact, the mechanical pressure can ensure that the contact can maintain good electrical connection in various use environments (such as slight vibration, movement, etc.), avoid equipment failure caused by poor contact;

[0039] Furthermore, the design of the conductive ring groove 6 and the conductive point groove 5 cooperates with the layout of the multiple positive contact points 7, and the close contact enables the current to be uniformly distributed between the contact points and the conductive grooves, and the optimized current distribution can improve the current transmission efficiency, reduce energy loss, and also reduce the risk of local overheating.

[0040] In the embodiment of the utility model, the positive contact point 7 and the negative contact point 8 are both elastic structures.

[0041] Firstly, the elastic structure can provide a certain contact pressure. When the power base 2 is connected with the liquid heating device body 1, the elastic contact points will be in close contact with the conductive ring groove 6 and the conductive point groove 5 under the action of their own elastic force. This contact pressure can ensure that even in the case of manufacturing tolerances, slight vibrations or size changes caused by temperature changes, etc., a good electrical connection can still be maintained.

[0042] Secondly, the elastic structure has a certain self-adaptive ability. In different use environments and connection states, the elastic contact points can adjust their own position and contact state according to the actual situation to adapt to various changes. For example, when the connection part is extruded or twisted by external force, the elastic contact points can deform to relieve stress, thereby maintaining stable electrical connection.

[0043] In addition, the elastic structure can also compensate for wear to some extent. With the increase in the number of uses, there may be some degree of wear between the contact points and the conductive grooves. The elastic contact points can compensate for this wear through their own elastic deformation, thereby prolonging the service life of the device.

[0044] Specifically, the positive contact 7 and the negative contact 8 can both be pogo pins.

[0045] In the embodiment of the utility model, two positive contacts 7 correspond to the conductive ring groove 6, and the two positive contacts 7 are symmetrically distributed on both sides of the conductive ring groove 6.

[0046] Symmetrically distributing the two positive contacts 7 on both sides of the conductive ring groove 6 enables the current to be evenly distributed between the two positive contacts 7 when flowing from the conductive ring groove 6 of the power base 2 into the liquid heating device body 1. This can avoid the concentration of current at a certain point, reduce local overheating and energy loss, and ensure the stability and efficiency of the heating process. The symmetrically distributed positive contacts 7 can form a balanced stress state when in contact with the conductive ring groove 6. This balance helps to maintain the stability of the connection and reduces the occurrence of poor contact or loose connection due to uneven stress. The symmetric design enables the two positive contacts 7 to support and work together even when subjected to a certain degree of external interference or vibration when in contact with the conductive ring groove 6, thereby improving the reliability and anti-interference ability of the connection.

[0047] In the embodiment of the utility model, the mating surface of the positive contact 7 and the conductive ring groove 6, and the mating surface of the negative contact 8 and the conductive point groove 5 are both arc surfaces.

[0048] The arc surface design can increase the contact area between the contact and the conductive groove in limited space. Compared with flat contact, the arc surface can better fit the shape of the conductive groove, so that the current can flow more smoothly through the contact part, reducing the contact resistance and improving the efficiency of electric energy transmission. The connection between the positive contact 7 and the conductive ring groove 6, and the connection between the negative contact 8 and the conductive point groove 5 can adapt to different angles to some extent. When there is a slight angle deviation during the connection of the equipment, the arc surface can adjust its shape to maintain good contact and improve the reliability of the connection. During the connection and use, the contact and the conductive groove will be subjected to certain pressure and friction force. The arc surface design can disperse these forces to a larger area, reduce local stress concentration, reduce the risk of wear and tear of the contact and the conductive groove, and prolong the service life of the equipment.

[0049] In the embodiment of the utility model, the power supply base 2 is provided with a power supply module (not shown), and the conductive point groove 5 and the conductive ring groove 6 are electrically connected with the power supply module.

[0050] The liquid heating equipment main body 1 is provided with a control unit (not shown) and a heating module (not shown), and the heating module, the positive contact 7 and the negative contact 8 are electrically connected with the control unit.

[0051] In the embodiment of the utility model, the connection mode of the power supply base 2 and the liquid heating equipment main body 1 includes clamping, magnetic attraction, knob type buckle connection or threaded connection.

[0052] The clamping mode utilizes the concave-convex cooperation of the mechanical structure, realizes the connection of the power supply base 2 and the liquid heating equipment main body 1 through specific clamping grooves and buckles, and the design principle is to ensure firm connection while facilitating quick connection and separation, which is suitable for scenes requiring frequent disassembly.

[0053] The magnetic attraction connection utilizes the attraction force of the magnetic material to make the two components mutually adsorbed, and the principle is to realize stable connection by reasonably arranging the magnetic material to ensure that sufficient magnetic force can be generated within a certain distance range, and the connection mode does not need accurate alignment and is more convenient to operate.

[0054] The knob type buckle connection realizes the firmness of the connection through the rotation of the buckle structure, and the principle is to utilize the rotation of the knob to drive the movement of the buckle to form reliable connection, and the buckle can be easily unlocked through reverse rotation.

[0055] The threaded connection is realized through the cooperation of the screw structure, the design principle is to utilize the rotation movement of the thread to make the two components gradually tightly combined to provide stable connection force.

[0056] Through different mechanical structure designs, users can conveniently connect or separate the two components according to actual requirements, and meet the requirements of portability, cleaning requirements and maintenance convenience in different use scenarios.

[0057] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
