Description

一种具备防烫伤功能的加热式加湿器A heating humidifier with anti-scalding function

技术领域Technical Field

本实用新型涉及加湿器技术领域，具体涉及一种具备防烫伤功能的加热式加湿器。The utility model relates to the technical field of humidifiers, in particular to a heating humidifier with an anti-scalding function.

背景技术Background technique

热蒸发型加湿器是将水在加热体中加热产生蒸气，用电机将蒸气送出，这种热蒸发型加湿器的蒸发效率低，能耗较大。为此，中国专利202121214553.9公开了一种种加湿器及医疗设备，参见图1，其包括壳体1、底座2和加热件3，壳体1设置在底座2上。壳体1包括内壳体11和外壳体12，内壳体11将外壳体12的内部空间分隔成第一腔体结构41和第二腔体结构42。内壳体11的下端与底座2之间设有通道结构43，通道结构43适于连通第一腔体结构41和第二腔体结构42。加热件3设置在底座2上，并伸入第一腔体结构41内。使用时，第二腔体结构42内的水通过通道结构43流进第一腔体结构41。然而，由于第一腔体结构41内的水的温度较高，若加湿器使用时发生倾倒，第一腔体结构41的水会洒出烫伤用户，用户烫伤部位组织会受损，造成肿胀，同时会引发剧烈疼痛，给用户带来极大的伤害。The thermal evaporation type humidifier heats water in a heating body to generate steam, and uses a motor to send the steam out. This type of thermal evaporation type humidifier has low evaporation efficiency and high energy consumption. To this end, Chinese Patent 202121214553.9 discloses a humidifier and medical equipment, referring to Figure 1, which includes a shell 1, a base 2 and a heating element 3, and the shell 1 is arranged on the base 2. The shell 1 includes an inner shell 11 and an outer shell 12, and the inner shell 11 divides the internal space of the outer shell 12 into a first cavity structure 41 and a second cavity structure 42. A channel structure 43 is provided between the lower end of the inner shell 11 and the base 2, and the channel structure 43 is suitable for connecting the first cavity structure 41 and the second cavity structure 42. The heating element 3 is arranged on the base 2 and extends into the first cavity structure 41. When in use, the water in the second cavity structure 42 flows into the first cavity structure 41 through the channel structure 43. However, since the temperature of the water in the first cavity structure 41 is relatively high, if the humidifier tips over during use, the water in the first cavity structure 41 will spill and scald the user. The tissue of the scalded part of the user will be damaged, causing swelling, and causing severe pain, causing great harm to the user.

此外，就加热式加湿器而言，加热件、进气流道、出雾流道是该类型加湿器固有机构，且被加热的水会位于出雾流道的底部以便空气带走水汽。由此，该类型的加湿器也存在一固有缺陷，即如上所述的当加热式加湿器倾倒时，被加热的水会沿出雾流道流出，最终烫伤用户。因此，为保证用户的使用安全，设计一种能在加湿器倾倒时防止温度较高的水烫伤用户的加湿器具有重要的使用意义。In addition, as far as the heating humidifier is concerned, the heating element, the air inlet channel, and the mist outlet channel are inherent mechanisms of this type of humidifier, and the heated water will be located at the bottom of the mist outlet channel so that the air can carry away the water vapor. Therefore, this type of humidifier also has an inherent defect, that is, as mentioned above, when the heating humidifier is tipped over, the heated water will flow out along the mist outlet channel and eventually scald the user. Therefore, in order to ensure the user's safety, it is of great significance to design a humidifier that can prevent the high-temperature water from scalding the user when the humidifier is tipped over.

实施例1Example 1

一种具备防烫伤功能的加热式加湿器，参见图2-4，包括储水箱10以及盖于储水箱10上的机头组件20，储水箱10可选用具有开口的水盘。机头组件20的底部设有隔热罩30、发热件40、挡水板50、风机60、进风流道和出雾流道。隔热罩30的顶部固定于机头组件20底部，其底部为开口结构，在机头组件20盖于储水箱10上的状态下，隔热罩30将储水箱10分隔为位于隔热罩30外的第一空间11和位于隔热罩30内的第二空间12，隔热罩30的侧壁或底部设有连通第一空间11和第二空间12的进水口31，当第二空间12内的水位降低时，第一空间11内的水通过进水口31流进第二空间12，以向第二空间12中补充水。发热件40自机头组件20的底部朝下伸出并位于隔热罩30内，用于加热第二空间12内的水。挡水板50活动连接于隔热罩30的底部，当机头组件20盖于储水箱10上时，挡水板50封堵隔热罩30底部的开口，当加湿器倾倒，机头组件20分离储水箱10，挡水板50受重力作用打开隔热罩30底部的开口。加湿器使用过程中，风机60驱动外部空气依次流经进风流道、第二空间12、出雾流道最终流出加湿器，以提高外界环境的湿度。A heating humidifier with a scald prevention function, see Figures 2-4, includes a water tank 10 and a head assembly 20 covering the water tank 10, and the water tank 10 can be selected to have an open water tray. The bottom of the head assembly 20 is provided with a heat insulation cover 30, a heating element 40, a water baffle 50, a fan 60, an air inlet channel and a mist outlet channel. The top of the heat insulation cover 30 is fixed to the bottom of the head assembly 20, and its bottom is an open structure. When the head assembly 20 covers the water tank 10, the heat insulation cover 30 divides the water tank 10 into a first space 11 outside the heat insulation cover 30 and a second space 12 inside the heat insulation cover 30. The side wall or bottom of the heat insulation cover 30 is provided with a water inlet 31 connecting the first space 11 and the second space 12. When the water level in the second space 12 is reduced, the water in the first space 11 flows into the second space 12 through the water inlet 31 to replenish water in the second space 12. The heating element 40 extends downward from the bottom of the head assembly 20 and is located in the heat insulation cover 30, and is used to heat the water in the second space 12. The water baffle 50 is movably connected to the bottom of the heat insulation cover 30. When the head assembly 20 is covered on the water storage tank 10, the water baffle 50 blocks the opening at the bottom of the heat insulation cover 30. When the humidifier is tilted, the head assembly 20 is separated from the water storage tank 10, and the water baffle 50 opens the opening at the bottom of the heat insulation cover 30 under the action of gravity. During the use of the humidifier, the fan 60 drives the external air to flow through the air inlet channel, the second space 12, and the mist outlet channel in sequence and finally flows out of the humidifier to increase the humidity of the external environment.

以上的加湿器，使用时，机头组件20盖在储水箱10上，此时挡水板50堵住隔热罩30底部的开口，隔热罩30将储水箱10分隔为位于隔热罩30外的第一空间11和位于隔热罩30内的第二空间12，第一空间11和第二空间12只通过进水口31连通，发热件40对第二空间12内的水进行加热，而不用对整个储水箱10中的水进行加热，这减少了需要加热的水量，极大缩短了加热时间，提高了加热效率，同时也节省了能源。当第二空间12内的水被蒸发，水位降低时，第一空间11内的水通过进水口31流进第二空间12，以向第二空间12补充水，防止第二空间12内的水被烧干。此外，通过设置挡水板50，当加湿器倾倒，储水箱10与机头组件20分离，挡水板50受重力或弹力作用打开隔热罩30底部的开口，第一空间11和第二空间12内的水混合，从而降低了第二空间12内的水的温度，使用户不容易被烫伤，甚至不被烫伤。When the above humidifier is in use, the head assembly 20 covers the water tank 10. At this time, the water baffle 50 blocks the opening at the bottom of the heat insulation cover 30. The heat insulation cover 30 divides the water tank 10 into a first space 11 located outside the heat insulation cover 30 and a second space 12 located inside the heat insulation cover 30. The first space 11 and the second space 12 are connected only through the water inlet 31. The heating element 40 heats the water in the second space 12 instead of heating the water in the entire water tank 10. This reduces the amount of water that needs to be heated, greatly shortens the heating time, improves the heating efficiency, and also saves energy. When the water in the second space 12 is evaporated and the water level drops, the water in the first space 11 flows into the second space 12 through the water inlet 31 to replenish water to the second space 12 to prevent the water in the second space 12 from being burned dry. In addition, by providing a water baffle 50, when the humidifier is tilted, the water tank 10 is separated from the head assembly 20, and the water baffle 50 opens the opening at the bottom of the heat insulation cover 30 under the action of gravity or elastic force, and the water in the first space 11 and the second space 12 are mixed, thereby reducing the temperature of the water in the second space 12, making it less likely for the user to be scalded, or even not scalded.

应当说明的是，以上的加湿器中，隔热罩30为顶部和底部均为开口的结构，顶部开口可穿过发热件40，底部开口则设置如上述所说的挡水板50。挡水板50的截面形状也可以根据实际需要进行设置，在本实施例中，其截面形状为圆形。此外，隔热罩30的底部基本位于靠近储水箱10底部的位置，当机头组件20盖在储水箱10上，挡水板50也靠近储水箱10底部。这样，当机头组件20盖在储水箱10上，挡水板50受储水箱10底部的限位从而保持封堵隔热罩30底部的开口，当机头组件20与储水箱10分离时便能打开开口。当然，为实现对挡水板50的限位功能，也可采用其他能够达到盖功能的结构，在此不再赘述。It should be noted that in the above humidifier, the heat shield 30 is a structure with openings at the top and bottom, the top opening can pass through the heating element 40, and the bottom opening is provided with the water baffle 50 as mentioned above. The cross-sectional shape of the water baffle 50 can also be set according to actual needs. In the present embodiment, its cross-sectional shape is circular. In addition, the bottom of the heat shield 30 is basically located near the bottom of the water tank 10. When the head assembly 20 covers the water tank 10, the water baffle 50 is also close to the bottom of the water tank 10. In this way, when the head assembly 20 covers the water tank 10, the water baffle 50 is limited by the bottom of the water tank 10 to keep the opening at the bottom of the heat shield 30 blocked, and the opening can be opened when the head assembly 20 is separated from the water tank 10. Of course, in order to realize the limiting function of the water baffle 50, other structures that can achieve the cover function can also be adopted, which will not be repeated here.

作为一种改进方案，参见图4-5，挡水板50包括截面形状均呈半圆状第一挡水板51和第二挡水板52，第一挡水板51和第二挡水板52均铰接于隔热罩30的底部。当机头组件20盖在储水箱10上，第一挡水板51和第二挡水板52合在隔热罩30的底部，受水槽底部的限位其不能转动，从而稳定地封堵隔热罩30底部的开口。当加湿器倾倒，机头组件20与储水箱10分离，在第一挡水板51和第二挡水板52自身以及水的重力下(或弹力)，第一挡水板51和第二挡水板52转动打开隔热罩30底部的开口，第一空间11和第二空间12内的水混合，从而降低了第二空间12内的水的温度。以上挡水板50在机头组件20与储水箱10分离时便能打开第一挡水板51和第二挡水板52，使用稳定性强，此外，其结构简单，便于生产、制造，挡水板也便于安装，有利于提高安装效率。As an improved solution, referring to Fig. 4-5, the water baffle 50 includes a first water baffle 51 and a second water baffle 52, both of which are semicircular in cross-section, and the first water baffle 51 and the second water baffle 52 are both hinged to the bottom of the heat insulation cover 30. When the head assembly 20 is covered on the water storage tank 10, the first water baffle 51 and the second water baffle 52 are combined at the bottom of the heat insulation cover 30, and they cannot rotate due to the limitation of the bottom of the water tank, thereby stably blocking the opening at the bottom of the heat insulation cover 30. When the humidifier is overturned, the head assembly 20 is separated from the water storage tank 10, and under the gravity (or elastic force) of the first water baffle 51 and the second water baffle 52 themselves and the water, the first water baffle 51 and the second water baffle 52 rotate to open the opening at the bottom of the heat insulation cover 30, and the water in the first space 11 and the second space 12 is mixed, thereby reducing the temperature of the water in the second space 12. The above water baffle plate 50 can open the first water baffle plate 51 and the second water baffle plate 52 when the head assembly 20 is separated from the water tank 10, and has strong stability in use. In addition, its structure is simple, easy to produce and manufacture, and the water baffle plate is also easy to install, which is beneficial to improving installation efficiency.

以上的挡水板结构，作为其它的可选方案，参见图6，挡水板50为一整块圆板，其顶部设有两个第三连接部53，每个第三连接部53上均水平向外延伸有滑动块531，隔热罩30的侧壁或底部上设有与滑动块531滑动配合的滑槽32，滑槽32沿竖直方向设置。当机头组件20盖在储水箱10上，挡水板50合在隔热罩30的底部，受水槽底部的限位其不能向下移动，从而稳定地封堵隔热罩30底部的开口。当加湿器倾倒，机头组件20与储水箱10分离，在挡水板50自身以及水的重力下，挡水板50相对于隔热罩30向下移动，隔热罩30底部的开口打开，第一空间11和第二空间12内的水混合，从而降低了第二空间12内的水的温度。以上设置可滑动的挡水板50开封堵或打开隔热罩30底部的开口，使用稳定性强，此外，该滑动结构简单，便于生产、制造、安装。The above water baffle structure is another optional solution, see FIG6 , the water baffle 50 is a whole circular plate, and two third connecting parts 53 are provided on the top thereof, and a sliding block 531 is horizontally extended outward on each third connecting part 53, and a slide groove 32 that slides with the sliding block 531 is provided on the side wall or the bottom of the heat insulation cover 30, and the slide groove 32 is arranged in the vertical direction. When the head assembly 20 is covered on the water storage tank 10, the water baffle 50 is closed at the bottom of the heat insulation cover 30, and it cannot move downward due to the limit of the bottom of the water tank, thereby stably blocking the opening at the bottom of the heat insulation cover 30. When the humidifier is tilted, the head assembly 20 is separated from the water storage tank 10, and under the gravity of the water baffle 50 itself and the water, the water baffle 50 moves downward relative to the heat insulation cover 30, and the opening at the bottom of the heat insulation cover 30 opens, and the water in the first space 11 and the second space 12 are mixed, thereby reducing the temperature of the water in the second space 12. The slidable water baffle plate 50 is provided to block or open the opening at the bottom of the heat insulation cover 30, and has strong stability in use. In addition, the sliding structure is simple and easy to produce, manufacture and install.

以上的挡水板结构，作为其它的可选方案，参见图7，隔热罩30靠近底部的位置设有第二连接孔33以及可拆卸穿设在第一连接孔5321的转轴34，转轴34沿隔热罩30的径向方向水平设置，转轴34可通过螺母等方式固定。挡水板50的顶面设有第一连接耳532，第一连接耳532上设有与转轴34转动配合的第一连接孔5321。装配时，转轴34穿过第一连接孔5321、第二连接孔33从而将挡水板50转动连接在隔热罩30底部。当机头组件20盖在储水箱10上，挡水板50合在隔热罩30的底部，受水槽底部的限位其不能翻转，从而稳定地封堵隔热罩30底部的开口。当加湿器倾倒，机头组件20与储水箱10分离，在挡水板50自身以及水的重力下，挡水板50向一侧翻转，隔热罩30底部的开口打开，第一空间11和第二空间12内的水混合，从而降低了第二空间12内的水的温度。以上设置转动的挡水板50开封堵或打开隔热罩30底部的开口，使用稳定性强，此外，该滑动结构简单，便于生产、制造、安装。The above water baffle structure is another optional solution, see FIG7 , the heat shield 30 is provided with a second connection hole 33 and a removable shaft 34 inserted in the first connection hole 5321 near the bottom, the shaft 34 is horizontally arranged along the radial direction of the heat shield 30, and the shaft 34 can be fixed by nuts and the like. The top surface of the water baffle 50 is provided with a first connection ear 532, and the first connection ear 532 is provided with a first connection hole 5321 that is rotatably matched with the shaft 34. During assembly, the shaft 34 passes through the first connection hole 5321 and the second connection hole 33, so that the water baffle 50 is rotatably connected to the bottom of the heat shield 30. When the head assembly 20 is covered on the water storage tank 10, the water baffle 50 is closed at the bottom of the heat shield 30, and it cannot be turned over due to the limit of the bottom of the water tank, thereby stably blocking the opening at the bottom of the heat shield 30. When the humidifier is overturned, the head assembly 20 is separated from the water storage tank 10, and the water baffle 50 is flipped to one side under the gravity of the water baffle 50 itself and the water, and the opening at the bottom of the heat insulation cover 30 is opened, and the water in the first space 11 and the second space 12 are mixed, thereby reducing the temperature of the water in the second space 12. The rotating water baffle 50 is set to block or open the opening at the bottom of the heat insulation cover 30, and the use stability is strong. In addition, the sliding structure is simple and easy to produce, manufacture and install.

在本实施例中提供了上述的三种挡水板的机构，可以理解的是，还可以采用其他的结构，如参见图8，直接在隔热罩30的底部设有密封圈54，密封圈54与储水箱10的底面密封配合，当机头组件20盖在储水箱10上，隔热罩30底部被密封，其只能从进水口31进入第二空间12。当然，也可以采用其他的结构，只要在机头组件20与储水箱10分离时，隔热罩30底部的开口能够打开，第一空间11和第二空间12内的水能够混合即可。In this embodiment, the above three water baffle mechanisms are provided. It is understandable that other structures can also be used. For example, referring to FIG8 , a sealing ring 54 is directly provided at the bottom of the heat shield 30. The sealing ring 54 is sealed with the bottom surface of the water storage tank 10. When the head assembly 20 is covered on the water storage tank 10, the bottom of the heat shield 30 is sealed, and it can only enter the second space 12 from the water inlet 31. Of course, other structures can also be used, as long as the opening at the bottom of the heat shield 30 can be opened when the head assembly 20 is separated from the water storage tank 10, and the water in the first space 11 and the second space 12 can be mixed.

以上方案中通过设置挡水板50来使机头组件20与储水箱10分离时打开隔热罩30底部的开口，以使第一空间11和第二空间12内的水混合从而降低第二空间12内的水温，防止烫伤用户。作为其他的防烫伤方案，参见图3，出雾流道远离隔热罩30的端部为出雾端21，出雾端21呈锥型，出雾端21内设有密封球24，密封球24的材料密度小于水的密度。当加湿器倾倒，密封球24受浮力浮起并随水流动，直到堵住出雾端21，防止第二空间12内的热水瞬间大量流到外部，烫伤用户(其倾倒状态示意图参见图9)。相比于利用重力原理堵住出雾端21，利用浮力的密封球24优势在于不管机头组件20倾斜多少度，只要出雾通道内有水流动，密封球24就会被推动，从而堵住出雾端21。而如果是利用重力，则需要机头组件20的出雾端21低于储水箱10端，密封球24才会动。In the above scheme, a water baffle 50 is provided to open the opening at the bottom of the heat insulation cover 30 when the head assembly 20 is separated from the water tank 10, so that the water in the first space 11 and the second space 12 are mixed, thereby reducing the water temperature in the second space 12 and preventing the user from being scalded. As another anti-scalding scheme, referring to FIG3, the end of the mist outlet channel away from the heat insulation cover 30 is the mist outlet end 21, the mist outlet end 21 is conical, and a sealing ball 24 is provided in the mist outlet end 21, and the material density of the sealing ball 24 is less than the density of water. When the humidifier is tilted, the sealing ball 24 floats up due to buoyancy and flows with the water until the mist outlet end 21 is blocked, preventing the hot water in the second space 12 from flowing to the outside in an instant and scalding the user (see FIG9 for a schematic diagram of its tilting state). Compared with using the principle of gravity to block the mist outlet end 21, the sealing ball 24 using buoyancy has the advantage that no matter how much the head assembly 20 is tilted, as long as there is water flowing in the mist outlet channel, the sealing ball 24 will be pushed, thereby blocking the mist outlet end 21. If gravity is used, the mist outlet end 21 of the head assembly 20 needs to be lower than the end of the water storage tank 10 so that the sealing ball 24 can move.

在储水箱10中，第一空间11通过进水口31来向第二空间12补水，这样，第二空间12内的水也能通过进水口31与第一空间11内的水进行热交换。为了进一步减少第二空间12内水的热量向第一空间11内传递，作为一种改进方案，参见图4，隔热罩30包括内隔热罩38以及套设于内隔热罩38外侧的外隔热罩39，内隔热罩38和外隔热罩39的顶部均设于机头组件20的底部。内隔热罩38的侧壁设有第一进水口381，外隔热罩39的侧壁设有第二进水口391，当然，两个进水口也可设置在对应隔热罩的底部。第一进水口381和第二进水口391错开设置。当第二空间12内缺水，第一空间11内的水依次流经第二进水口391、内隔热罩38与外隔热罩39之间的间隙和第一进水口381，最终向第二空间12内补水。由于内隔热罩38与外隔热罩39之间的间隙较小，其在该位置的流动速度较慢，热传递效率，从而能够保证第二空间12内的加热效率。另外，若在以上隔热罩30的底部设有密封圈54，这样，第二空间12内的热水的热量不易传递至第一空间11内，能进一步保证第二空间12内的加热效率。In the water storage tank 10, the first space 11 replenishes water to the second space 12 through the water inlet 31, so that the water in the second space 12 can also exchange heat with the water in the first space 11 through the water inlet 31. In order to further reduce the heat transfer of the water in the second space 12 to the first space 11, as an improved solution, referring to FIG. 4, the heat insulation cover 30 includes an inner heat insulation cover 38 and an outer heat insulation cover 39 sleeved on the outer side of the inner heat insulation cover 38, and the tops of the inner heat insulation cover 38 and the outer heat insulation cover 39 are both arranged at the bottom of the head assembly 20. The side wall of the inner heat insulation cover 38 is provided with a first water inlet 381, and the side wall of the outer heat insulation cover 39 is provided with a second water inlet 391. Of course, the two water inlets can also be arranged at the bottom of the corresponding heat insulation cover. The first water inlet 381 and the second water inlet 391 are staggered. When the second space 12 lacks water, the water in the first space 11 flows through the second water inlet 391, the gap between the inner heat insulation cover 38 and the outer heat insulation cover 39, and the first water inlet 381 in sequence, and finally replenishes water into the second space 12. Since the gap between the inner heat insulation cover 38 and the outer heat insulation cover 39 is small, the flow speed at this position is slow, and the heat transfer efficiency is high, thereby ensuring the heating efficiency in the second space 12. In addition, if a sealing ring 54 is provided at the bottom of the above heat insulation cover 30, the heat of the hot water in the second space 12 is not easily transferred to the first space 11, which can further ensure the heating efficiency in the second space 12.

在本实施例中，作为一种优选方案，参见图11，机头组件20的底部设有容置腔22，容置腔22的底部为与储水箱10连通的开口，该开口为第一出风口222，容置腔22的侧壁即为机头组件20的侧壁，该处也设有开口，该开口为第一进风口221。隔热罩30上设有连通第一空间11和第二空间12的第二进风口35，该第二进风口35高于储水箱10的最高液面。第一进风口221、容置腔22、储水箱10和第二进风口35形成进风流道。在机头组件20中，隔热罩30内的空间竖直向上连通至外部，该通道为出雾通道。风机60包括电机61和风叶62，电机61设于机头组件20内，电机61的转轴34伸至容置腔22内并与风叶62连接。使用时，外部的空气依次流经第一进风口221、容置腔22、第一空间11、第二进风口35、第二空间12，然后从第二空间12上方吹出。在该结构中，外部空气不经能带走第二空间12内的水汽，还能带走第一空间11内的水汽，加湿效果好。In this embodiment, as a preferred solution, referring to FIG. 11 , a receiving chamber 22 is provided at the bottom of the head assembly 20, and the bottom of the receiving chamber 22 is an opening connected to the water tank 10, which is a first air outlet 222. The side wall of the receiving chamber 22 is the side wall of the head assembly 20, and an opening is also provided therein, which is a first air inlet 221. A second air inlet 35 connecting the first space 11 and the second space 12 is provided on the heat shield 30, and the second air inlet 35 is higher than the highest liquid level of the water tank 10. The first air inlet 221, the receiving chamber 22, the water tank 10 and the second air inlet 35 form an air inlet channel. In the head assembly 20, the space inside the heat shield 30 is vertically connected to the outside, and the channel is a mist outlet channel. The fan 60 includes a motor 61 and a fan blade 62, and the motor 61 is arranged in the head assembly 20, and the rotating shaft 34 of the motor 61 extends into the receiving chamber 22 and is connected to the fan blade 62. When in use, the external air flows through the first air inlet 221, the accommodating cavity 22, the first space 11, the second air inlet 35, the second space 12 in sequence, and then blows out from the top of the second space 12. In this structure, the external air can not only take away the water vapor in the second space 12, but also take away the water vapor in the first space 11, and the humidification effect is good.

当然，以上的进风流道也可采用其他结构，如：参见图10，容置腔22的底部不与储水箱10连通，而直接连至隔热罩30的第二进风口35，第一进风口221、容置腔22和第二进风口35形成进风流道。使用时，外部的空气依次流经第一进风口221、容置腔22、第二进风口35、第二空间12，然后从第二空间12上方吹出。在该结构中，外部空气不流经第一空间11，而直接流进第二空间12，空气流通较为顺畅，阻力小。Of course, the above air inlet flow channel may also adopt other structures, such as: referring to FIG. 10, the bottom of the accommodating chamber 22 is not connected to the water storage tank 10, but directly connected to the second air inlet 35 of the heat insulation cover 30, and the first air inlet 221, the accommodating chamber 22 and the second air inlet 35 form an air inlet flow channel. When in use, the external air flows through the first air inlet 221, the accommodating chamber 22, the second air inlet 35, and the second space 12 in sequence, and then blows out from the top of the second space 12. In this structure, the external air does not flow through the first space 11, but directly flows into the second space 12, and the air circulation is relatively smooth with less resistance.

以上的进风流道的结构中，第二进风口35设于靠近储水箱10中最高水面的上方位置。这样，当加湿器发生倾倒，第一空间11内的水也可以通过第二进风口35进入第一空间11，从而能进一步降低第二空间12内的水，从而提高防烫伤效果。In the above structure of the air inlet flow channel, the second air inlet 35 is arranged at a position above the highest water level in the water storage tank 10. In this way, when the humidifier is tilted, the water in the first space 11 can also enter the first space 11 through the second air inlet 35, so that the water in the second space 12 can be further reduced, thereby improving the anti-scalding effect.

作为一种改进方案，参见图12-13，机头组件20还设有电源以及与电源电连接的开关26，电源设于机头组件20内，开关26设于机头组件20的底部，其上设有触臂261。在机头组件20盖于储水箱10上时，储水箱10顶住开关26的触臂261，开关26被导通，即机头组件20内的电路被导通，当机头组件20分离储水箱10时，触臂261不再按压，开关26断开，机头组件20内的电路断开。通过设置以上的开关26和触臂261，开关26在机头组件20盖在储水箱10上时电路导通，分离时断开，这保证了使用过程中电路结构的安全。作为其他可选实施方式，机头组件20的底部设有第一耦合器27，储水箱10的顶面设有与第一耦合器27位置相对的第二耦合器28，耦合器为现有技术，在此不再赘述。机头组件20内设有与第一耦合器27电连接的电源线25，当然，电源线25也可以设置在储水箱10内。使用时，当机头组件20盖于储水箱10上，通过第一耦合器27和第二耦合器28将机头组件20和储水箱10的电路导通，当机头组件20分离储水箱10时，第一耦合器27和第二耦合器28分离，机头组件20和储水箱10的电路被断开。As an improved solution, referring to FIGS. 12-13 , the handpiece assembly 20 is further provided with a power source and a switch 26 electrically connected to the power source. The power source is provided in the handpiece assembly 20, and the switch 26 is provided at the bottom of the handpiece assembly 20, on which a contact arm 261 is provided. When the handpiece assembly 20 is covered on the water tank 10, the water tank 10 presses against the contact arm 261 of the switch 26, and the switch 26 is turned on, that is, the circuit in the handpiece assembly 20 is turned on. When the handpiece assembly 20 is separated from the water tank 10, the contact arm 261 is no longer pressed, the switch 26 is turned off, and the circuit in the handpiece assembly 20 is turned off. By providing the above switch 26 and contact arm 261, the switch 26 is turned on when the handpiece assembly 20 is covered on the water tank 10, and is turned off when separated, which ensures the safety of the circuit structure during use. As another optional embodiment, a first coupler 27 is provided at the bottom of the head assembly 20, and a second coupler 28 is provided on the top surface of the water tank 10, which is opposite to the first coupler 27. The coupler is a prior art and will not be described in detail here. A power cord 25 electrically connected to the first coupler 27 is provided in the head assembly 20. Of course, the power cord 25 can also be provided in the water tank 10. When in use, when the head assembly 20 is covered on the water tank 10, the circuit between the head assembly 20 and the water tank 10 is connected through the first coupler 27 and the second coupler 28. When the head assembly 20 is separated from the water tank 10, the first coupler 27 and the second coupler 28 are separated, and the circuit between the head assembly 20 and the water tank 10 is disconnected.

实施例2Example 2

实施例1中提供了一种能够防烫伤的加热式加湿器以及加湿器的部分结构。然而，以上加湿器在长期使用后会滋生细菌，影响用户的建康。为此，本实施例提供一种便于清洗的加热式加湿器。该加湿器的部分结构与实施例1中的相同，其相同的结构不再赘述。以下对不同之处做具体说明。In Example 1, a heating humidifier capable of preventing scalding and a partial structure of the humidifier are provided. However, the above humidifier will breed bacteria after long-term use, affecting the health of the user. For this reason, this embodiment provides a heating humidifier that is easy to clean. Part of the structure of the humidifier is the same as that in Example 1, and the same structure will not be repeated. The differences are described in detail below.

为方便清洗储水箱10以及机头组件20，参见图14-25，机头组件20的底部设有第一连接部23，隔热罩30的顶部设有第二连接部36，第二连接部36与第一连接部23可拆卸连接。当加湿器使用完一段时间后，储水箱10、隔热罩30以及发热件40上会滋生细菌，附着一些杂物。为此，将机头组件20与储水箱10分离，由于储水箱10内没有设置其他结构，清洗过程较为方便。另外，由于隔热罩30与机头组件20为可拆卸连接，清洗时可将隔热罩30拆卸从而分别清洗隔热罩30和发热件40，这便于用户进行清洗，避免了因隔热罩30和发热件40相互阻挡而导致隔热罩30的内壁和发热件40清洗困难的问题。In order to facilitate the cleaning of the water storage tank 10 and the head assembly 20, referring to Figures 14-25, a first connecting portion 23 is provided at the bottom of the head assembly 20, and a second connecting portion 36 is provided at the top of the heat insulation cover 30, and the second connecting portion 36 is detachably connected to the first connecting portion 23. After the humidifier has been used for a period of time, bacteria will grow on the water storage tank 10, the heat insulation cover 30 and the heating element 40, and some debris will be attached. For this reason, the head assembly 20 is separated from the water storage tank 10. Since no other structure is set in the water storage tank 10, the cleaning process is more convenient. In addition, since the heat insulation cover 30 is detachably connected to the head assembly 20, the heat insulation cover 30 can be disassembled during cleaning so as to clean the heat insulation cover 30 and the heating element 40 separately, which is convenient for users to clean and avoids the problem that the inner wall of the heat insulation cover 30 and the heating element 40 are difficult to clean due to the mutual obstruction of the heat insulation cover 30 and the heating element 40.

作为一种改进方案，参见14-17，第二连接部36呈圆环状，第二连接部36的侧壁设有三个连接段364，每个连接段364与水平面之间都存在倾斜角，第一连接部23上设有与连接段364配合的三个支撑部234。装配时，第二连接部36通过连接段364拧紧到第一连接部23的支撑部234上，两者相互抵接，从而将隔热罩30连接至机头组件20底部，当需要拆卸时将其拧松拆下即可。。以上的连接段和支撑部结构简单，连接稳定可靠，其相比于传动的螺纹连接方式，由于接触面积少，摩擦力小，使用效果更好，同时制造该结构的模具成本低。此外，以上结构在装配时，隔热罩30的转动角度小于180°，使用简单。应当说明的是，以上连接段和支撑部的数量及角度可根据需要进行设置。另外，综合考虑连接稳定性以及拆装便利性，以上的螺旋连接结构为一种综合效果较好的连接结构。As an improved solution, see 14-17, the second connecting part 36 is annular, and the side wall of the second connecting part 36 is provided with three connecting sections 364, each connecting section 364 has an inclination angle with the horizontal plane, and the first connecting part 23 is provided with three supporting parts 234 cooperating with the connecting section 364. During assembly, the second connecting part 36 is tightened to the supporting part 234 of the first connecting part 23 through the connecting section 364, and the two are in contact with each other, so that the heat shield 30 is connected to the bottom of the head assembly 20, and it can be loosened and removed when it needs to be disassembled. . The above connecting section and supporting part have a simple structure, stable and reliable connection, and compared with the threaded connection mode of transmission, due to the small contact area and small friction, the use effect is better, and the mold cost of manufacturing the structure is low. In addition, when the above structure is assembled, the rotation angle of the heat shield 30 is less than 180°, which is simple to use. It should be noted that the number and angle of the above connecting sections and supporting parts can be set as needed. In addition, considering the connection stability and the convenience of assembly and disassembly, the above spiral connection structure is a connection structure with better overall effect.

以上的第一连接部23与第二连接部36之间的连接结构，作为其它的可选方案，参见图18-19，第一连接部23呈圆环状，其侧壁设有第一连接螺纹231，第二连接部36的侧壁设有与第一连接螺纹231进行螺纹连接的第二连接螺纹361。使用时，隔热罩30通过第二连接部36的第二连接螺纹361连接于机头组件20的第一连接部23的第一连接螺纹231即可实现装配，这种连接方式可靠，且其拆装方便，便于用户拆卸隔热罩30。As another optional solution, the connection structure between the first connection part 23 and the second connection part 36 is shown in FIGS. 18-19. The first connection part 23 is annular, and its side wall is provided with a first connection thread 231, and the side wall of the second connection part 36 is provided with a second connection thread 361 threadedly connected to the first connection thread 231. When in use, the heat shield 30 can be assembled by connecting the second connection thread 361 of the second connection part 36 to the first connection thread 231 of the first connection part 23 of the head assembly 20. This connection method is reliable and easy to assemble and disassemble, so that the user can disassemble the heat shield 30.

以上的第一连接部23与第二连接部36之间的连接结构，作为其它的可选方案，参见图20-21，第一连接部23上设有卡凸232，第二连接部36上设有与卡凸232卡接配合的卡槽362。使用时，隔热罩30将第二连接部36的卡槽362与机头组件20的第一连接部23的卡凸232卡接配合即可实现装配，卡凸232与卡槽362之间的卡接结构较为稳定，连接效果好(相比于螺纹、螺旋连接，其拆装过程相对困难)。As another optional solution, the connection structure between the first connection part 23 and the second connection part 36 is shown in FIGS. 20-21 . The first connection part 23 is provided with a clamping protrusion 232, and the second connection part 36 is provided with a clamping groove 362 that is clamped with the clamping protrusion 232. When in use, the heat shield 30 can be assembled by clamping the clamping groove 362 of the second connection part 36 with the clamping protrusion 232 of the first connection part 23 of the head assembly 20. The clamping structure between the clamping protrusion 232 and the clamping groove 362 is relatively stable and has a good connection effect (compared with threaded and spiral connections, the disassembly process is relatively difficult).

以上的第一连接部23与第二连接部36之间的连接结构，作为其它的可选方案，参见图22-23，第一连接部23和第二连接部36之间设有弹性件233，第二连接部36通过弹性件233与第一连接部23过盈配合。使用时，隔热罩30将第二连接部36与机头组件20的第一连接部23之间通过弹性件233过盈连接即可实现装配。以上通过弹性件233过盈连接隔热罩30和机头组件20，其结构简单，拆装方便(相比于螺纹、螺旋连接，其使用时间达到一定程度后，弹性件233会老化，连接容易失效，连接稳定性相对较差)。As another optional solution, the connection structure between the first connection part 23 and the second connection part 36 is shown in FIGS. 22-23 . An elastic member 233 is provided between the first connection part 23 and the second connection part 36, and the second connection part 36 is interference fit with the first connection part 23 through the elastic member 233. When in use, the heat shield 30 can be assembled by interference connection between the second connection part 36 and the first connection part 23 of the head assembly 20 through the elastic member 233. The heat shield 30 and the head assembly 20 are interference connected by the elastic member 233, and the structure is simple and easy to disassemble and assemble (compared with threaded and spiral connections, after a certain period of use, the elastic member 233 will age, the connection will easily fail, and the connection stability is relatively poor).

以上的第一连接部23与第二连接部36之间的连接结构，作为其它的可选方案，参见图24-25，第二连接部36上设有第二连接耳363，第二连接耳363与第一连接部23螺丝连接。使用时，通过螺丝连接连接第二耳和机头第一连接部23即可实现装配。以上通过螺丝连接，其连接较为可靠(相比于螺纹、螺旋连接，其拆装麻烦，对于需要反复拆装的使用情况适用性较差)。As another optional solution, the connection structure between the first connection part 23 and the second connection part 36 is shown in FIGS. 24-25 . The second connection part 36 is provided with a second connection ear 363, and the second connection ear 363 is screwed to the first connection part 23. When in use, the second ear and the first connection part 23 of the machine head can be assembled by screwing. The above screw connection is more reliable (compared with threaded and spiral connections, which are troublesome to disassemble and assemble, and are less suitable for use situations that require repeated disassembly and assembly).

应当说明的是，以上除了螺纹连接的其他三种连接方式，其使用效果虽不及螺纹连接，但是，也是一种实用性强的连接方式。It should be noted that, although the other three connection methods mentioned above are not as effective as the threaded connection, they are also a highly practical connection method.

作为一种改进方案，参见图14-21，隔热罩30的顶部设有环形台阶37，环形台阶37的侧壁为上述第二连接部36，第一连接部23的底部与环形台阶37的底部抵接，这样，第一连接部23和第二连接部36之间的连接更加稳定。对于第一连接螺纹231与第二连接螺纹361进行螺纹连接的连接方式而言，由于第一连接部23的底部与环形台阶37的底部抵接，这两个抵接面会产生摩擦力，防止第一连接部23和第二连接部36之间发生松动，进一步保证两者之间的连接稳定性。As an improved solution, referring to FIGS. 14-21 , an annular step 37 is provided on the top of the heat shield 30, and the side wall of the annular step 37 is the second connection portion 36, and the bottom of the first connection portion 23 abuts against the bottom of the annular step 37, so that the connection between the first connection portion 23 and the second connection portion 36 is more stable. For the connection mode of threaded connection between the first connection thread 231 and the second connection thread 361, since the bottom of the first connection portion 23 abuts against the bottom of the annular step 37, the two abutting surfaces will generate friction, preventing the first connection portion 23 and the second connection portion 36 from loosening, and further ensuring the connection stability between the two.

作为一种改进方案，参见图4，发热件40包括一体的第一发热件41以及水平设于第一发热件41底部的第二发热件42，第一发热件41呈柱状，其自机头组件20的底部朝下伸出，第二发热件42呈环状。以上柱状的第一发热件41以及环形的第二加热件，在清洗时便于进行清洗，同时环形的第二加热件也增大了加热面积，保证了加热效率。应当说明的是，以上的发热件40可为加热棒等，其为现有技术，在此不再赘述。As an improved solution, referring to FIG. 4 , the heating element 40 includes an integrated first heating element 41 and a second heating element 42 horizontally arranged at the bottom of the first heating element 41. The first heating element 41 is columnar and extends downward from the bottom of the head assembly 20, and the second heating element 42 is annular. The above columnar first heating element 41 and the annular second heating element are easy to clean, and the annular second heating element also increases the heating area and ensures the heating efficiency. It should be noted that the above heating element 40 can be a heating rod, etc., which is a prior art and will not be described in detail here.

在本实施例中，若隔热罩30采用如实施例1中的双层的结构，那内隔热罩38和外隔热罩39上均设有第二连接部36，相应的，第一连接部23上设有内连接部(未图示)和外连接部(未图示)，内连接部与内隔热罩38的第二连接部36可拆卸连接，外连接部与外隔热罩39的第二连接部36可拆卸连接，具体的可拆卸连接方式可采用以上的任一种连接方式。内隔热罩38和外隔热罩39为分体式的结构也便于清洗。In this embodiment, if the heat shield 30 adopts a double-layer structure as in Embodiment 1, the inner heat shield 38 and the outer heat shield 39 are both provided with a second connection portion 36. Accordingly, the first connection portion 23 is provided with an inner connection portion (not shown) and an outer connection portion (not shown). The inner connection portion is detachably connected to the second connection portion 36 of the inner heat shield 38, and the outer connection portion is detachably connected to the second connection portion 36 of the outer heat shield 39. The specific detachable connection method can adopt any of the above connection methods. The inner heat shield 38 and the outer heat shield 39 are split structures, which are also convenient for cleaning.
