Description
技术领域technical field
本实用新型涉及锅盖开关技术领域，具体而言，涉及压力锅及其防开盖装置。The utility model relates to the technical field of a pot lid switch, in particular to a pressure cooker and an anti-opening device thereof.
背景技术Background technique
压力锅，又称高压锅，高压锅的原理很简单，因为水的沸点受气压影响，气压越高，沸点越高。在高山、高原上，气压不到1个大气压，不到100℃水就能沸腾，鸡蛋用普通锅具是煮不熟的。在气压大于1个大气压时，水就要在高于100℃时才会沸腾。人们常用的高压锅就是利用这个原理设计的。高压锅把水相当紧密地封闭起来，水受热蒸发产生的水蒸气不能扩散到空气中，只能保留在高压锅内，就使高压锅内部的气压高于1个大气压，也使水要在高于100℃时才沸腾，这样高压锅内部就形成高温高压的环境，饭就容易很快做熟，并且相当酥烂。但是，当锅内压力大于4KPa时，如果意外开盖，会对操作者带来很多的危险。Pressure cooker, also known as pressure cooker, the principle of pressure cooker is very simple, because the boiling point of water is affected by the air pressure, the higher the air pressure, the higher the boiling point. On high mountains and plateaus, the air pressure is less than 1 atmospheric pressure, water can boil at less than 100°C, and eggs cannot be boiled with ordinary pots. When the air pressure is greater than 1 atmospheric pressure, water will boil when it is higher than 100°C. People's commonly used pressure cookers are designed using this principle. The pressure cooker seals the water quite tightly, and the water vapor produced by the evaporation of water cannot diffuse into the air, and can only be kept in the pressure cooker, so that the pressure inside the pressure cooker is higher than 1 atmospheric pressure, and the water must be kept at a temperature higher than 100°C When it boils, the inside of the pressure cooker will form a high-temperature and high-pressure environment, and the rice will be cooked easily and quickly, and it will be quite crispy. However, when the pressure in the pot is greater than 4KPa, if the lid is accidentally opened, it will bring a lot of danger to the operator.

The first torsion spring 2 is arranged on the vertical branch of the "L", and the horizontal branch of the "L" is superimposed on the cover-opening latch 17 to generate lateral friction force.
上盖锁扣1、开盖锁扣17一一对应，上盖锁扣1的数目至少为2个，处于防开盖装置的两端，对上盖产生均衡作用力。如果上盖锁扣1较多，则选择在横截面边缘均匀分配。There is a one-to-one correspondence between the upper cover lock 1 and the opening lock 17, and the number of upper cover locks 1 is at least two, which are located at both ends of the anti-opening device and produce a balanced force on the upper cover. If there are many locks 1 on the upper cover, choose to distribute them evenly on the edge of the cross section.
其中，为了对驱动按钮9产生按动的缓冲力，传动组件还包括：两个以上缓冲弹簧7，缓冲弹簧7以传动杆12为对称轴相对设置，产生均衡作用力，每个缓冲弹簧7的首端与驱动按钮9固定连接，缓冲弹簧7受压后，其尾端穿过壳体8顶住传动板14。按压驱动按钮9，缓冲弹簧7首先受到挤压；当缓冲弹簧7挤压到一定程度后，驱动按钮9与传动杆12的首端6接触，继续推动驱动按钮9时，驱动按钮9推动传动杆12移动；产生缓冲力，避免驱动按钮9与传动杆12发生硬性作用力。Wherein, in order to generate a buffering force for pressing the drive button 9, the transmission assembly also includes: more than two buffer springs 7, the buffer springs 7 are relatively arranged with the transmission rod 12 as a symmetrical axis to generate a balanced force, and each buffer spring 7 The head end is fixedly connected with the drive button 9 , and after the buffer spring 7 is pressed, its tail end passes through the housing 8 to withstand the transmission plate 14 . Press the driving button 9, the buffer spring 7 is first squeezed; when the buffer spring 7 is squeezed to a certain extent, the driving button 9 contacts the head end 6 of the transmission rod 12, and when the driving button 9 is pushed continuously, the driving button 9 pushes the transmission rod 12 to move; to generate a buffer force to prevent the driving button 9 and the transmission rod 12 from generating a hard force.
传动杆12的首端6距离传动板14的长度为L1，缓冲弹簧7的首端距离传动板14的长度为L2，L2大于L1。The length of the head end 6 of the transmission rod 12 from the transmission plate 14 is L1, the length of the head end of the buffer spring 7 from the transmission plate 14 is L2, and L2 is greater than L1.
为了促使传动板14能够推动上盖锁扣1转动，传动板14的两端分别延伸推板3，推板3的延伸端随传动板14转动中顶住上盖锁扣1，并推动上盖锁扣1。In order to promote the transmission plate 14 to push the upper cover lock 1 to rotate, the two ends of the transmission plate 14 respectively extend the push plate 3, and the extension end of the push plate 3 withstands the upper cover lock 1 while the transmission plate 14 rotates, and pushes the upper cover. Buckle 1.
在传动杆12向壳体8内部移动时，传动弹簧13会对传动杆12施加反作用力，推动传动杆12向反方向移动，为了避免传动杆12从传动板14中脱离，传动杆12的尾端与传动板14进行锁扣连接，以防止传动杆12向所述驱动按钮方向移动时滑出传动板14。When the transmission rod 12 moves to the inside of the housing 8, the transmission spring 13 will exert a reaction force on the transmission rod 12, and push the transmission rod 12 to move in the opposite direction. In order to prevent the transmission rod 12 from breaking away from the transmission plate 14, the tail of the transmission rod 12 The end is locked and connected with the transmission plate 14, so as to prevent the transmission rod 12 from sliding out of the transmission plate 14 when it moves towards the direction of the driving button.
具体到锁扣连接，其具体的方式为如图3所示：传动杆12穿入传动板1414的通孔16中，锁扣连接的方式为：传动杆12的尾端设有凸沿15，凸沿15受所述通孔16的边缘阻挡。As for the locking connection, the specific method is as shown in Figure 3: the transmission rod 12 penetrates the through hole 16 of the transmission plate 1414, and the locking connection method is: the tail end of the transmission rod 12 is provided with a convex edge 15, The ledge 15 is blocked by the edge of said through hole 16 .
为了避免驱动按钮9无限制向壳体8内部移动，驱动按钮9向壳体8内部延伸两个以上的延伸臂4，延伸臂4随驱动按钮9向壳体8内部移动中会顶住壳体8。In order to prevent the drive button 9 from moving to the inside of the housing 8 without restriction, the drive button 9 extends more than two extension arms 4 to the inside of the housing 8, and the extension arms 4 will withstand the housing when the drive button 9 moves to the inside of the housing 8 8.
基于上述分析，传动板14受两方面的作用力：一方面的作用力为传动弹簧13的反作用力，另一方面的作用力为上盖锁扣1和开盖锁扣17之间的摩擦力F。当压力锅的内锅压力大于4KPa时，上盖锁扣1和开盖锁扣17之间的摩擦力为F，传动弹簧13的最大作用力小于F。则，内锅压力达到4KPa以上时，推动板无法被推动，上盖锁扣1无法转动，上盖锁扣1、开盖锁扣17之间摩擦力大，上盖被锁死，无法打开。如果压力较低或内外压持平，则，传动弹簧13会推动推动板转动，推动板推动上盖锁扣1转动，上盖解锁，上盖被打开。Based on the above analysis, the transmission plate 14 is subjected to two forces: on the one hand, the force is the reaction force of the transmission spring 13; F. When the inner pot pressure of the pressure cooker was greater than 4KPa, the frictional force between the upper cover lock 1 and the uncap lock 17 was F, and the maximum active force of the transmission spring 13 was less than F. Then, when the pressure of the inner pot reaches more than 4KPa, the push plate cannot be pushed, the upper cover lock 1 cannot rotate, and the friction force between the upper cover lock 1 and the opening lock 17 is large, and the upper cover is locked and cannot be opened. If the pressure is low or the internal and external pressures are equal, the transmission spring 13 will push the push plate to rotate, and the push plate will push the upper cover lock 1 to rotate, the upper cover is unlocked, and the upper cover is opened.
为了进一步避免上盖锁扣意外转动，该防开盖装置还包括：浮子、摆杆；其中，浮子处于壳体的对应腔体中，并在腔体中随锅内压力上下浮动；摆杆通过套有第三扭簧的第三轴连接于壳体的上部，摆杆以第三轴为转动中心左右摆动；摆杆在浮子对应位置开有用于容纳上浮的浮子的凹槽；摆杆的一端压住上盖锁扣。摆杆压住上盖锁扣，上盖锁扣无法以第一扭簧为中心旋转，则压力锅的盖不会意外打开；如果摆杆水平摆动，脱离对上盖锁扣的压力，上盖锁扣能够旋转，压力锅则可以打开。基于这种原理，浮子在锅内压力达到预设值值时上浮，卡入摆杆的凹槽中，相当于卡住摆杆，防止摆杆水平向左右摆动；一旦锅内压力低于预设值，浮子沉落，摆杆的水平向左右摆动不受阻力，可以自由摆动，脱离对上盖锁扣的压力。通过这种方式，能够避免压力锅锅内存在一定压力时的意外开盖。In order to further avoid the accidental rotation of the lock of the upper cover, the anti-opening device also includes: a float and a swing rod; wherein, the float is located in the corresponding cavity of the housing, and floats up and down in the cavity with the pressure inside the pot; the swing rod passes through The third shaft covered with the third torsion spring is connected to the upper part of the housing, and the swing rod swings left and right with the third shaft as the rotation center; the swing rod has a groove for accommodating the floating float at the corresponding position of the float; one end of the swing rod Press the top cover latch. The swing rod presses the lock of the upper cover, and the lock of the upper cover cannot rotate around the first torsion spring, so the lid of the pressure cooker will not be opened accidentally; The clasp turns and the pressure cooker opens. Based on this principle, the float floats up when the pressure in the pot reaches the preset value, and is stuck in the groove of the swing rod, which is equivalent to blocking the swing rod to prevent the swing rod from swinging horizontally; once the pressure in the pot is lower than the preset value value, the float sinks, the horizontal swing of the pendulum rod is free from resistance, and can swing freely, breaking away from the pressure on the lock of the upper cover. In this way, accidental opening of the lid when there is a certain pressure inside the pressure cooker can be avoided.
