本申请中的压力开关装置通过将壳体组件分为可拆卸连接的第一壳体和第二壳体，第一壳体和第二壳体围合形成相互连通的泄压腔和测压腔，则便于将泄压组件和压力开关组件分别安装于泄压腔和测压腔内，泄压组件中阀体封堵泄压口时。泄压腔与外界大气隔绝，阀体开启泄压口时，外界大气通过泄压口进入泄压腔，进而与气压接口连通，从而实现了泄压的功能。同时，由于测压腔与泄压腔相互连通，则当泄压腔内的气体压力与外界大气压力水平一致时，测压腔也恢复至与外界大气相同的压力水平，从而能够使得压力开关组件复位。另外压力开关装置仅设置一个与泄压腔和测压腔同时连通的气压接口，则避免压力开关组件与泄压组件分别与抽真空容器连通时接口较多的问题，同时也避免了二者之间通过导气管连通导致的接口多的问题，从而可以减小压力开关组件和/或泄压阀组件与真空容器之间漏气的几率。The pressure switch device in the present application divides a housing component into a first housing and a second housing which are detachably connected, and the first housing and the second housing are enclosed to form a pressure relief chamber and a pressure measuring chamber which communicate with each other. , It is convenient to install the pressure relief component and the pressure switch component in the pressure relief cavity and the pressure measuring cavity respectively, when the valve body in the pressure relief component plugs the pressure relief port. The pressure relief chamber is isolated from the outside atmosphere. When the valve body opens the pressure relief port, the outside atmosphere enters the pressure relief chamber through the pressure relief port, and then communicates with the air pressure interface, thereby achieving the function of pressure relief. At the same time, because the pressure measuring chamber and the pressure relief chamber communicate with each other, when the gas pressure in the pressure relief chamber is consistent with the external atmospheric pressure level, the pressure measuring chamber also returns to the same pressure level as the external atmosphere, thereby enabling the pressure switch assembly Reset. In addition, the pressure switch device is provided with only one air pressure interface that communicates with the pressure relief chamber and the pressure measuring chamber at the same time. This avoids the problem of a large number of interfaces when the pressure switch component and the pressure relief component are in communication with the vacuum container. There are many problems caused by the communication between the air ducts, which can reduce the probability of air leakage between the pressure switch assembly and / or the pressure relief valve assembly and the vacuum container.

本申请提出一种压力开关装置1，应用于具有抽真空功能的产品。The present application proposes a pressure switch device 1 which is applied to a product having a vacuuming function.

在本申请实施例中，请结合图1至图3所示，该压力开关装置1包括壳体组件、泄压组件30及压力开关组件400，壳体组件包括密封连接的第一壳体10和第二壳体20，第一壳体10和第二壳体20围合形成泄压腔101和测压腔102，泄压腔101的腔壁设置有与泄压腔101连通的泄压口110；泄压组件30安装于泄压腔101内，泄压组件30包括可封堵或开启泄压口110的阀体301；压力开关组件400安装于测压腔102内；其中，第一壳体10或者第二壳体20上开设有一个用以与外界容器连通的气压接口210，气压接口210连通泄压腔101和测压腔102。In the embodiment of the present application, please refer to FIG. 1 to FIG. 3. The pressure switch device 1 includes a housing component, a pressure relief component 30, and a pressure switch component 400. The housing component includes a first housing 10 and a sealed connection. The second casing 20, the first casing 10, and the second casing 20 enclose to form a pressure relief chamber 101 and a pressure measuring chamber 102. The cavity wall of the pressure relief chamber 101 is provided with a pressure relief port 110 communicating with the pressure relief chamber 101. The pressure relief assembly 30 is installed in the pressure relief chamber 101, and the pressure relief assembly 30 includes a valve body 301 that can block or open the pressure relief port 110; the pressure switch assembly 400 is installed in the pressure measurement chamber 102; wherein, the first housing 10 or the second casing 20 is provided with an air pressure interface 210 for communicating with an external container, and the air pressure interface 210 communicates with the pressure relief chamber 101 and the pressure measurement chamber 102.

壳体组件包括密封连接的第一壳体10和第二壳体20，第一壳体10和第二壳体20围合形成相互连通的泄压腔101和测压腔102，则可以理解的是，在装配之前第一壳体10与第二壳体20呈分体设置，以便于工人将泄压组件30和压力开关组件400分别安装于泄压腔101和测压腔102内；而将泄压组件30和压力开关组件400装配完之后，为了保证泄压腔101与测压腔102除气压接口210处的其余部位的密闭性，第一壳体10与第二壳体20之间密封连接。具体地，第一壳体10与第二壳体20之间可以夹设有密封圈，或者也可以通过粘接或者焊接等方式密封连接第一壳体10与第二壳体20，以使得装配完之后的第一壳体10与第二壳体20之间不易分开，保证了泄压腔101和测压腔102相对外界大气具有良好的密闭性。第一壳体10或者第二壳体20上开设有一个用以与外界容器连通的气压接口210，且该气压接口210连通泄压腔101和测压腔102，则通过导管将该气压接口210与外界容器连通时，同时能够实现外界容器与泄压腔101和测压腔102的连通效果，保证了外界容器内气压与该压力开关装置1内的泄压腔101与测压腔102的气压压力一致的效果。可以理解的是，测压腔102内的压力开关组件400在检测到气压在某个范围值之内便会接通主控板，从而将信号传递至对容器进行抽真空的真空泵22，使其停止工作。同时通过在泄压腔101的腔壁设置与泄压腔101连通的泄压口110，在泄压口110处设有可封堵或开启泄压口110的阀体301，则当用户需要对容器内的气体进行泄压时，可通过控制阀体301打开泄压口110，则使得大气压力通过泄压口110进入泄压腔101，进而通过气压接口210进入容器内，从而达到容器内的压力与大气压力一致，实现泄压的效果。同时，由于泄压腔101与测压腔102相互连通，则当泄压腔101达到与外界大气压力一致的压力水平时，测压腔102也达到了与外界大气压力一致的压力水平，从而测压腔102内的压力开关组件400便会恢复原来的状态。另外，可以理解的是，为了保证压力开关组件400能够准确地实现通断隔离效果，本申请测压腔102与压力开关组件400接触的部分为非金属材质。进一步地，为了使得泄压效率提高，气压接口210可开设于泄压腔101的腔壁上，从而使得外界大气通过泄压口110后再流至气压接口210的路径较短，从而能够快速通过气压接口210进入容器内，提高了泄压的效率。The housing assembly includes a first housing 10 and a second housing 20 that are hermetically connected, and the first housing 10 and the second housing 20 are enclosed to form a pressure relief chamber 101 and a pressure measuring chamber 102 that communicate with each other. Yes, before assembly, the first casing 10 and the second casing 20 are separated, so that workers can install the pressure relief assembly 30 and the pressure switch assembly 400 in the pressure relief chamber 101 and the pressure measuring chamber 102, respectively. After the pressure relief assembly 30 and the pressure switch assembly 400 are assembled, in order to ensure the tightness of the rest of the pressure relief chamber 101 and the pressure measuring chamber 102 except for the air pressure interface 210, the first casing 10 and the second casing 20 are sealed. connection. Specifically, a sealing ring may be sandwiched between the first casing 10 and the second casing 20, or the first casing 10 and the second casing 20 may be sealed and connected by means of bonding or welding, so as to make assembly After completion, the first casing 10 and the second casing 20 are not easily separated, thereby ensuring that the pressure relief chamber 101 and the pressure measuring chamber 102 have a good airtightness to the outside atmosphere. The first casing 10 or the second casing 20 is provided with an air pressure interface 210 for communicating with an external container, and the air pressure interface 210 communicates with the pressure relief chamber 101 and the pressure measurement chamber 102, and the air pressure interface 210 is connected through a catheter. When communicating with the external container, the communication effect between the external container and the pressure relief chamber 101 and the pressure measuring chamber 102 can be achieved at the same time, thereby ensuring the pressure in the external container and the pressure in the pressure relief chamber 101 and the pressure measuring chamber 102 in the pressure switch device 1 Consistent pressure effect. It can be understood that, when the pressure switch assembly 400 in the pressure measuring chamber 102 detects that the air pressure is within a certain range value, it will turn on the main control board, thereby transmitting the signal to the vacuum pump 22 for evacuating the container, so that stop working. At the same time, by providing a pressure relief port 110 communicating with the pressure relief chamber 101 on the cavity wall of the pressure relief chamber 101, a valve body 301 is provided at the pressure relief port 110, which can block or open the pressure relief port 110. When the gas in the container is depressurized, the pressure relief port 110 can be opened through the control valve body 301, so that the atmospheric pressure enters the pressure relief chamber 101 through the pressure relief port 110, and then enters the container through the air pressure interface 210, thereby reaching the inside of the container. The pressure is consistent with the atmospheric pressure to achieve the effect of pressure relief. At the same time, since the pressure relief chamber 101 and the pressure measuring chamber 102 communicate with each other, when the pressure relief chamber 101 reaches a pressure level consistent with the external atmospheric pressure, the pressure measuring chamber 102 also reaches a pressure level consistent with the external atmospheric pressure, thereby measuring The pressure switch assembly 400 in the pressure chamber 102 returns to its original state. In addition, it can be understood that, in order to ensure that the pressure switch assembly 400 can accurately realize the on-off isolation effect, the part of the pressure measuring chamber 102 and the pressure switch assembly 400 of the present application that is in contact with the pressure switch assembly 400 is made of non-metal material. Further, in order to improve the pressure relief efficiency, the air pressure interface 210 may be opened on the cavity wall of the pressure relief chamber 101, so that the external atmosphere passes through the pressure relief port 110 and then the path to the air pressure interface 210 is short, so that it can pass quickly. The air pressure interface 210 enters the container, which improves the efficiency of pressure relief.

另外，在本申请技术方案中，通过第一壳体10和第二壳体20围合形成的泄压腔101和测压腔102能够相互连通，且泄压腔101内安装有泄压组件30，测压腔102内安装有压力开关组件400，实现了泄压组件30与压力开关组件400整合于一体的效果。并且，通过整合于同一壳体组件内后，二者均可通过同一个气压接口210连通外界容器，而不需要分别从两个组件的外壳21上开设接通口连通于外界容器内。如此可以减少接口数量，从而减小了漏气的几率。In addition, in the technical solution of the present application, the pressure-relieving cavity 101 and the pressure-measuring cavity 102 formed by enclosing the first casing 10 and the second casing 20 can communicate with each other, and a pressure-releasing component 30 is installed in the pressure-releasing cavity 101. A pressure switch assembly 400 is installed in the pressure measuring chamber 102, and the pressure relief assembly 30 and the pressure switch assembly 400 are integrated into one. In addition, after being integrated in the same housing component, both can communicate with the external container through the same air pressure interface 210, and there is no need to open a connection port from the housing 21 of the two components to communicate with the external container. This can reduce the number of interfaces, thereby reducing the chance of air leakage.

具体地，为了使压力开关装置1具有两个相互连通的腔，即泄压腔101和测压腔102，第一壳体10和第二壳体20围合形成的空间中部可设置一隔板，该隔板的两端可同时封堵壳体组件相对的两侧壁，同时在隔板上开设有一通孔，从而实现第一壳体10与第二壳体20围合形成两个腔，且两个腔相互连通的效果。当然，隔板的一端封堵壳体组件其中的一侧内壁，另一端朝与该侧相对的另一侧延伸但并不与另一侧壁连接，从而实现泄压腔101与测压腔102的互通效果。如此设置，可以避免泄压组件30、压力开关组件400与外界容器之间通过三通管相互连通而导致至少具有三个接口的结构，从而大大减小了漏气的几率，提高了测压的准确度。Specifically, in order for the pressure switch device 1 to have two interconnected cavities, namely a pressure relief cavity 101 and a pressure measurement cavity 102, a partition may be provided in the middle of the space formed by the first casing 10 and the second casing 20 The two ends of the partition plate can simultaneously block the two opposite side walls of the casing assembly, and a through hole is opened on the partition plate, so that the first casing 10 and the second casing 20 are enclosed to form two cavities. And the effect of the two cavities communicating with each other. Of course, one end of the partition plate closes one of the inner walls of the housing assembly, and the other end extends toward the other side opposite the side but is not connected to the other side wall, so as to realize the pressure relief chamber 101 and the pressure measurement chamber 102 Interoperability effect. In this way, the structure with at least three interfaces caused by the pressure relief assembly 30, the pressure switch assembly 400 and the external container to communicate with each other through the tee can be avoided, thereby greatly reducing the probability of air leakage and improving the pressure measurement. Accuracy.

本申请中压力开关装置1的壳体组件分为可拆卸连接的第一壳体10和第二壳体20，第一壳体10和第二壳体20围合形成相互连通的泄压腔101和测压腔102，则便于将泄压组件30和压力开关组件400分别安装于泄压腔101和测压腔102内，泄压组件30中阀体301封堵泄压口110时，泄压腔101与外界大气隔绝，阀体301开启泄压口110时，外界大气通过泄压口110进入泄压腔101，进而与气压接口210连通，从而实现了泄压的功能。同时，由于测压腔102与泄压腔101相互连通，则当泄压腔101内的气体压力与外界大气压力水平一致时，测压腔102也恢复至与外界大气相同的压力水平，从而能够使得压力开关组件400复位。另外仅设置一个与泄压腔101和测压腔102同时连通的气压接口210，则避免压力开关组件400与泄压组件30分别与抽真空容器连通时接口较多的问题，同时也避免了二者之间通过导气管连通导致的接口多的问题，从而可以减小压力开关组件400和/或泄压阀组件与真空容器之间漏气的几率。In the present application, the housing component of the pressure switch device 1 is divided into a first housing 10 and a second housing 20 that are detachably connected, and the first housing 10 and the second housing 20 are enclosed to form a pressure relief cavity 101 that communicates with each other.

When valve body 301 in pressure relief assembly 30 blocks pressure relief port 110, the pressure is released. The cavity 101 is isolated from the outside atmosphere. When the valve body 301 opens the pressure relief port 110, the outside atmosphere enters the pressure relief chamber 101 through the pressure relief port 110, and then communicates with the air pressure interface 210, thereby realizing the pressure relief function. At the same time, since the pressure measuring chamber 102 and the pressure releasing chamber 101 are interconnected, when the pressure of the gas in the pressure releasing chamber 101 is consistent with the external atmospheric pressure level, the pressure measuring chamber 102 is also restored to the same pressure level as the external atmosphere, thereby enabling The pressure switch assembly 400 is reset. In addition, only one air pressure interface 210 is provided to communicate with the pressure relief chamber 101 and the pressure measurement chamber 102 at the same time, thereby avoiding the problem of a large number of interfaces when the pressure switch assembly 400 and the pressure relief module 30 communicate with the vacuum container, respectively, and also avoids two The problem that there are many interfaces caused by the communication between the air ducts can reduce the probability of air leakage between the pressure switch assembly 400 and / or the pressure relief valve assembly and the vacuum container.

两个固定连接的筒体100可以为一体的结构以保证两个筒体100连接的稳定性；也可以采用分体的结构，然后通过一些连接件或连接结构将两个筒体100固定连接在一起，例如螺钉连接或者卡扣连接等。第二壳体20采用与两个筒体100的敞口适配并与两个筒体100密封连接的封盖200，则封盖200与两个筒体100分别围合可形成上述的泄压腔101和测压腔102。具体地，可以是封盖200与两个筒体100分别围合的整个空间分别为泄压腔101和测压腔102，也可以是筒体100内安装有其他部件，封盖200与其他部件围合形成泄压腔101或者测压腔102。基于上述结构，则泄压组件30与压力开关组件400先分别安装于两个筒体100内部的泄压腔101和测压腔102，然后再将封盖200分别与两个筒体100进行密封连接。为了保证泄压腔101与测压腔102除气压接口121处的其余部位的密闭性，封盖120上具有安装密封件的安装槽，密封件安装于安装槽后，其与封盖200整体盖合筒体100并使得密封件能够夹设于封盖200与筒体100之间。安装槽对密封件具有限位效果，保证密封件与封盖120具有较好的连接效果。The two fixedly connected cylinders 100 may be an integrated structure to ensure the stability of the connection between the two cylinders 100; a separate structure may also be adopted, and then the two cylinders 100 are fixedly connected to each other through some connectors or connection structures. Together, such as screw connection or snap connection. The second housing 20 adopts a cover 200 that is adapted to the openings of the two cylinders 100 and is tightly connected to the two cylinders 100. Then, the cover 200 and the two cylinders 100 are respectively enclosed to form the aforementioned pressure relief. Cavity 101 and pressure measurement cavity 102. Specifically, the entire space enclosed by the cover 200 and the two cylinders 100 may be the pressure relief chamber 101 and the pressure measurement chamber 102, respectively, or other components may be installed in the cylinder 100, and the cover 200 and other components may be installed therein. Enclose to form a pressure relief cavity 101 or a pressure measurement cavity 102. Based on the above structure, the pressure relief assembly 30 and the pressure switch assembly 400 are respectively installed in the pressure relief chamber 101 and the pressure measuring chamber 102 inside the two cylinders 100, and then the cover 200 is sealed with the two cylinders 100 respectively. connection. In order to ensure the tightness of the pressure relief chamber 101 and the pressure measuring chamber 102 except for the air pressure interface 121, the cover 120 has a mounting groove for installing a seal. After the seal is installed in the installation groove, it is integrally covered with the cover 200. The cylinder 100 is closed and the seal can be sandwiched between the cover 200 and the cylinder 100. The mounting groove has a limiting effect on the seal, and ensures that the seal and the cover 120 have a better connection effect.

进一步地，为了便于泄压组件30与压力开关组件400能够分别安装于两个筒体100内，即便于将泄压组件30与压力开关组件400安装到位，例如泄压组件30中的阀体301需要安装于泄压口110处，本实施例中泄压口110开设于筒体100，以便于工人安装阀体301时能够以筒体100上的泄压口110为基准进行安装。同时更好地实现泄压腔101与测压腔102能够同时与气压接口210连通，则本实施例中将气压接口210开设于封盖200。并且，由于封盖200与筒体100之间需要密封连接，为了不影响封盖200与筒体100连接处的密封效果，本实施例中封盖200还具有连通泄压腔101与测压腔102的气压通道201，以供泄压腔101与测压腔102通过该气压通道201相互连通。由于封盖200通常为塑料件，在注塑成型过程中，基于封盖200具有气压通道201的方案，出于工艺可制造性考虑，封盖200侧壁的下端面与水平面可呈锐角设置，以便于封盖200的成型制造过程中，有利于抽芯形成上述的气压通道201。Further, in order to facilitate the pressure relief assembly 30 and the pressure switch assembly 400 to be installed in the two cylinders 100 respectively, even if the pressure relief assembly 30 and the pressure switch assembly 400 are installed in place, for example, the valve body 301 in the pressure relief assembly 30 It needs to be installed at the pressure relief port 110. In this embodiment, the pressure relief port 110 is opened at the cylinder 100, so that when a worker installs the valve body 301, it can be installed based on the pressure relief port 110 on the cylinder 100. At the same time, it is better to realize that the pressure relief chamber 101 and the pressure measuring chamber 102 can communicate with the air pressure interface 210 at the same time. In this embodiment, the air pressure interface 210 is opened on the cover 200. In addition, since the sealing cover 200 and the cylindrical body 100 need to be sealed, in order not to affect the sealing effect of the connection between the sealing cover 200 and the cylindrical body 100, in this embodiment, the sealing cover 200 also has a pressure relief chamber 101 and a pressure measuring chamber. The air pressure channel 201 of 102 is used for the pressure relief chamber 101 and the pressure measurement chamber 102 to communicate with each other through the air pressure channel 201. Because the cover 200 is usually a plastic part, during the injection molding process, based on the scheme that the cover 200 has a gas pressure channel 201, for the sake of process manufacturability, the lower end surface of the side wall of the cover 200 and the horizontal plane can be set at an acute angle so During the molding and manufacturing process of the cover 200, it is advantageous to pull the core to form the aforementioned air pressure channel 201.

当然，可以理解的是，本申请并不局限于将泄压口110开设于筒体100、将气压接口210开设于封盖200以及将气压通道201开设于封盖200。只要是能够保证气压接口210与泄压口110连通，泄压腔101与测压腔102连通即可。例如，基于上述连通条件，泄压口110、气压接口210与气压通道201还可同时开设于筒体100上；或者任意其中两个开设于筒体100，另外一个开设于封盖200；或者任意其中两个开设于封盖200，另外一个开设于筒体100。Of course, it can be understood that the present application is not limited to opening the pressure relief port 110 on the cylinder 100, the air pressure interface 210 on the cover 200, and the air pressure channel 201 on the cover 200. As long as it can ensure that the air pressure interface 210 communicates with the pressure relief port 110 and the pressure relief chamber 101 communicates with the pressure measurement chamber 102. For example, based on the above-mentioned communication conditions, the pressure relief port 110, the air pressure interface 210, and the air pressure channel 201 can also be opened on the cylinder 100 at the same time; or any two of them can be opened on the cylinder 100 and the other on the cover 200; or Two of them are opened in the cover 200 and the other is opened in the cylinder 100.

如图3所示，为了实现测压腔102的测压效果，安装有压力开关组件400的筒体100的底壁具有压力口120，封盖200朝向压力口120的一侧罩合有密封罩500，密封罩200夹设于封盖200与筒体100之间，且封盖200与密封罩500围合形成测压腔102；压力开关组件400包括与密封罩500的内底壁抵接的接触片410、夹持于接触片410与封盖200之间的第一弹簧430及穿设封盖200的接线插针420，接线插针420的一端朝压力口120的方向延伸并与接触片410之间设置有间距。As shown in FIG. 3, in order to achieve the pressure measurement effect of the pressure measurement chamber 102, the bottom wall of the cylinder 100 on which the pressure switch assembly 400 is installed has a pressure port 120, and a side of the cover 200 facing the pressure port 120 is covered with a sealing cover. 500, the sealing cover 200 is sandwiched between the sealing cover 200 and the cylinder 100, and the sealing cover 200 and the sealing cover 500 are enclosed to form a pressure measuring chamber 102; the pressure switch assembly 400 includes abutting with the inner bottom wall of the sealing cover 500 The contact piece 410, the first spring 430 sandwiched between the contact piece 410 and the cover 200, and the connection pin 420 penetrating the cover 200. One end of the connection pin 420 extends toward the pressure port 120 and contacts the contact piece. A space is provided between 410.

在本申请技术方案中，底壁是指筒体100的敞口相对（或者与封盖200相对）的壁。安装有压力开关组件400的筒体100的底壁具有压力口120，封盖200朝向压力口120的一侧罩合有密封罩500，密封罩500夹设于封盖200与筒体100之间，则密封罩500与封盖200围合形成了一个腔体，该腔体的内部空间即为上述的测压腔102，可以理解的是，该密封罩500可盖合该压力口120。此处的密封罩500的材质为软性材质，例如橡胶或硅胶等，一方面利用其粘性或者通过密封连接结构实现与封盖200的密封效果；另一方面当测压腔102内的负压达到设定值时，外界大气可以通过压力口120对密封罩500施加压力，从而密封罩500正对压力口120的部分可发生形变。进一步地，压力开关组件400包括与密封罩500的内底壁抵接的接触片410和穿设封盖200的接线插针420，可以理解的是，该接触片410为导电接触片410，接线插针420一端朝压力口120的方向延伸并与接触片410之间设置有间距，即接线插针420与接触片410处于断开状态，二者之间没有电性连接。接线插针420的另一端穿设封盖200用以与主控板电性连接。接线插针420穿设封盖200，则封盖200上具有供接线插针420穿设的通孔，为了避免接线插针420沿轴向滑动，接线插针420与该通孔可过盈配合或者接线插针420的外壁与通孔内壁固定连接，比如可通过粘接的方式将接线插针420与通孔的内壁固定连接。另外，插针通常为两根，以便电性连接电源的正极和负极。In the technical solution of the present application, the bottom wall refers to a wall opposite to the opening of the cylinder 100 (or opposite to the cover 200). The bottom wall of the cylinder 100 on which the pressure switch assembly 400 is installed has a pressure port 120, and a side of the cover 200 facing the pressure port 120 is sealed with a sealing cap 500, which is sandwiched between the cover 200 and the cylinder 100. Then, the seal cover 500 and the cover 200 are enclosed to form a cavity, and the inner space of the cavity is the above-mentioned pressure measurement cavity 102. It can be understood that the seal cover 500 can cover the pressure port 120. The material of the sealing cover 500 here is a soft material, such as rubber or silicone. On the one hand, its sealing effect with the cover 200 is achieved by using its viscosity or through a sealing connection structure; on the other hand, when the negative pressure in the pressure measuring chamber 102 is When the set value is reached, the outside atmosphere can apply pressure to the sealing cover 500 through the pressure port 120, so that the portion of the sealing cover 500 facing the pressure port 120 may be deformed. Further, the pressure switch assembly 400 includes a contact piece 410 in contact with the inner bottom wall of the sealing cover 500 and a connection pin 420 penetrating the cover 200. It can be understood that the contact piece 410 is a conductive contact piece 410 for wiring One end of the pin 420 extends in the direction of the pressure port 120 and a distance is provided between the pin 420 and the contact piece 410, that is, the connection pin 420 and the contact piece 410 are in an open state, and there is no electrical connection between them. The other end of the connection pin 420 is provided with a cover 200 for electrically connecting with the main control board. The connection pin 420 passes through the cover 200, and the cover 200 has a through hole for the connection pin 420 to pass through. In order to prevent the connection pin 420 from sliding in the axial direction, the connection pin 420 and the through hole can be interference fit. Or the outer wall of the wiring pin 420 is fixedly connected to the inner wall of the through hole, for example, the wiring pin 420 can be fixedly connected to the inner wall of the through hole by an adhesive method. In addition, there are usually two pins, in order to electrically connect the positive and negative poles of the power supply.

另外，通过第一弹簧430一端抵持接触片410背离密封罩500的一侧，另一端抵持封盖200的顶壁，则第一弹簧430能够对接触片410施加弹力以使得接触片410能够与密封罩500紧紧贴合，从而实现密封罩500受大气压力的抵持作用而发生形变后能够带动接触片410同步运动的效果。当测压腔102内的气压到达预设值后，外界大气压通过压力口120抵持密封罩500，密封罩500发生形变并抵持接触片410以克服第一弹簧430的弹力，驱使接触片410朝接线插针420的方向运动，进而接触片410与接线插针420相互接触，实现二者的电性连接效果，从而与主控板接通，主控板传递信号至真空泵22，使其停止对容器进行抽真空过程。In addition, with one end of the first spring 430 against the side of the contact piece 410 facing away from the sealing cover 500 and the other end against the top wall of the cover 200, the first spring 430 can apply an elastic force to the contact piece 410 so that the contact piece 410 can The sealing cover 500 is closely attached to the sealing cover 500, thereby achieving the effect that the sealing cover 500 can be driven to move synchronously after the sealing cover 500 is deformed by the atmospheric pressure. When the air pressure in the pressure measuring chamber 102 reaches a preset value, the external atmospheric pressure against the seal cover 500 passes through the pressure port 120, and the seal cover 500 deforms and resists the contact piece 410 to overcome the elastic force of the first spring 430 and drive the contact piece 410. Move in the direction of the connection pin 420, and then the contact piece 410 and the connection pin 420 contact each other to achieve the electrical connection effect of the two, thereby connecting with the main control board, and the main control board transmits a signal to the vacuum pump 22 to stop it Vacuum the container.

进一步地，接线插针420背离接触片410的一端穿设封盖200，则该端可穿出封盖200，也可位于封盖200内。为了便于接线插针420与主控板进行电性连接，本实施例中可选接线插针420背离接触片410的一端穿出封盖200的顶壁。Further, the end of the connecting pin 420 facing away from the contact piece 410 is provided with a cover 200, and the end may pass through the cover 200 or be located in the cover 200. In order to facilitate the electrical connection between the connection pin 420 and the main control board, an end of the optional connection pin 420 facing away from the contact piece 410 penetrates the top wall of the cover 200 in this embodiment.

如图3所示，基于上述压力开关包括第一弹簧430的方案，为了避免第一弹簧430在径向上具有较大运动，接触片410背离密封罩500的一侧凸设有若干沿周向间隔分布的第一限位柱412，第一弹簧430的一端抵接于接触片410的中部并被第一限位柱412的内侧壁径向限位。As shown in FIG. 3, based on the solution that the pressure switch includes the first spring 430, in order to prevent the first spring 430 from having a large movement in the radial direction, a side of the contact piece 410 facing away from the sealing cover 500 is provided with a plurality of circumferential intervals. In the distributed first limiting post 412, one end of the first spring 430 abuts the middle of the contact piece 410 and is radially limited by the inner sidewall of the first limiting post 412.

若干个第一限位柱412沿接触片410的周向间隔分布，使得这些第一限位柱412围合成的内部区域可供第一弹簧430放置，从而实现对第一弹簧430径向限位的效果，减小第一弹簧430在径向上的移动位移或弯曲程度，使得第一弹簧430对接触片410的弹力方向尽可能呈与接触片410的片面垂直的方向，实现接触片410与密封罩500底壁较好的贴合效果。当然，在其他实施例中，接触片410背离密封罩500的一侧还可凸设有第一限位环320，可以理解的是，第一限位环320与若干沿周向分布的第一限位柱412均能对其围合的内部区域内的第一弹簧430具有较好的限位效果。A plurality of first limiting posts 412 are distributed along the circumferential direction of the contact piece 410, so that the internal area surrounded by the first limiting posts 412 can be placed by the first spring 430, thereby achieving radial limit of the first spring 430. Effect, reducing the movement displacement or bending degree of the first spring 430 in the radial direction, so that the direction of the spring force of the first spring 430 on the contact piece 410 is as perpendicular to the surface of the contact piece 410 as possible, so as to achieve the contact piece 410 and seal. The bottom wall of the cover 500 has a better fit effect. Of course, in other embodiments, a first limiting ring 320 may also be protruded on the side of the contact piece 410 facing away from the sealing cover 500. It can be understood that the first limiting ring 320 and a plurality of first distributed rings Each of the limiting posts 412 can have a good limiting effect on the first spring 430 in the enclosed inner region.

进一步地，如图3所示，封盖200的顶壁凸设有第二限位柱220，第二限位柱220位于第一限位柱412与密封罩500的侧壁之间，且第二限位柱220至接触片410的距离大于或等于接线插针420至接触片410的距离。Further, as shown in FIG. 3, the top wall of the cover 200 is convexly provided with a second limiting post 220. The second limiting post 220 is located between the first limiting post 412 and the side wall of the sealing cover 500. The distance between the two limiting posts 220 and the contact piece 410 is greater than or equal to the distance between the connecting pin 420 and the contact piece 410.

通过第二限位柱220位于第一限位柱412与密封罩500的侧壁之间，使得接触片410在朝封盖200顶壁的方向运动时，能够避免在接触片410与接线插针420接触之前，接触片410上设置的第一限位柱412便提前顶持第二限位柱220，从而使得第二限位柱220对接触片410的运动造成干涉影响。The second limiting post 220 is located between the first limiting post 412 and the side wall of the sealing cover 500, so that when the contact piece 410 moves toward the top wall of the cover 200, the contact piece 410 and the connection pin can be avoided. Before the contact of 420, the first limit post 412 provided on the contact piece 410 supports the second limit post 220 in advance, so that the second limit post 220 interferes with the movement of the contact piece 410.

另外，可以理解的是，为了能够保证接触片410与接线插针420能够接触，第二限位柱220至接触片410的距离大于或等于接线插针420至接触片410的距离。进一步地，为了避免与接触片410抵接的密封罩500变形量过大而导致的意外损坏现象，第二限位柱220至接触片410的距离可等于接线插针420至接触片410的距离。如此设置，不仅可以保证接触片410能够与接线插针420良好接触，而且还能减少密封罩500具有较大的形变而导致的意外损坏现象。In addition, it can be understood that in order to ensure that the contact piece 410 and the contact pin 420 can be in contact, the distance between the second limiting post 220 and the contact piece 410 is greater than or equal to the distance between the contact pin 420 and the contact piece 410. Further, in order to avoid the accidental damage caused by the deformation of the sealing cover 500 that is in contact with the contact piece 410, the distance between the second limiting post 220 and the contact piece 410 may be equal to the distance between the contact pin 420 and the contact piece 410. . This arrangement can not only ensure that the contact piece 410 can make good contact with the connection pin 420, but also reduce accidental damage caused by the large deformation of the sealing cover 500.

In addition, the protrusions 411 and the accommodation grooves 510 are provided, so that the contact piece 410 has a predetermined position effect when the contact piece 410 is installed in the sealing cover 500, and the assembly process of the contact piece 410 and the sealing cover 500 is facilitated. Of course, in other embodiments, the bottom wall of the sealing cover 500 may also be convex to form a protrusion facing away from the pressure port 120. At the same time, the contact piece 410 has a groove adapted to the protrusion, and the protrusion snaps into the groove. The connection effect between the sealing cover 500 and the contact piece 410 is realized inside. In addition, the convexity of the bottom wall of the sealing cover 500 in the direction of the pressure port 120 is also beneficial to improving the sensitivity of the sealing cover 500 to the external atmospheric pressure, so that the contact piece 410 and the connection pin 420 can be driven to contact or separate from each other in time.

本申请技术方案中的压力开关装置1，如图1或图3所示，为了实现能够实现泄压的功能，泄压组件30中的阀体301包括穿设泄压口110并与泄压口110适配的杆本体310，杆本体310位于泄压腔101内的一端径向凸设有限位环320，限位环320与泄压腔101的底壁之间还夹设有密封圈303，密封圈303套设于杆本体310外。The pressure switch device 1 in the technical solution of the present application, as shown in FIG. 1 or FIG. 3, in order to realize the function of releasing pressure, the valve body 301 in the pressure relief assembly 30 includes a pressure relief port 110 and communicates with the pressure relief port. 110 adaptable rod body 310, a stop ring 320 protruding radially from one end of the rod body 310 inside the pressure relief chamber 101, and a seal ring 303 is also sandwiched between the limit ring 320 and the bottom wall of the pressure relief chamber 101, The sealing ring 303 is sleeved outside the rod body 310.

泄压口110设置为与外界大气连通。通过在泄压口110处设置有杆本体310，杆本体310位于泄压腔101内的一端径向凸设有限位环320，该限位环320与泄压腔101的底壁之间夹设有密封圈303，且密封圈303套设于杆本体310外，则此时密封圈303与杆本体310共同实现封堵泄压口110的效果，避免外界大气通过泄压口110进入泄压腔101，进而通过气压接口210进入容器内而影响抽真空的效果。而当泄压腔101（或者测压腔102；或者容器内）的气压达到预定值后，上述的压力开关组件400中的接触片410与接线端子接通并电性连接主控板，主控板反馈信号至真空泵22以使真空泵22停止对容器内的气体抽真空。此时用户若想实现对容器内气体进行泄压的操作，只需将杆本体310朝泄压腔101内部方向推动，此时杆本体310运动带动密封圈303运动，从而密封圈303与泄压腔101的底壁之间具有了间隙，外界空气通过泄压口110，进而通过密封圈303与泄压腔101底壁的间隙中进入泄压腔101内，继而连通测压腔102以及通过气压接口210连通容器内部，实现了泄压的效果。The pressure relief port 110 is provided to communicate with the outside atmosphere. A rod body 310 is provided at the pressure relief port 110, and a limit ring 320 is radially protruding from one end of the rod body 310 located in the pressure relief cavity 101. The limit ring 320 is sandwiched between the limit ring 320 and the bottom wall of the pressure relief cavity 101. There is a sealing ring 303, and the sealing ring 303 is sleeved outside the rod body 310. At this time, the sealing ring 303 and the rod body 310 jointly achieve the effect of blocking the pressure relief port 110, and prevent the outside atmosphere from entering the pressure relief chamber through the pressure relief port 110 101, and then enter the container through the air pressure interface 210 to affect the effect of vacuuming. When the air pressure in the pressure relief chamber 101 (or the pressure measuring chamber 102; or the container) reaches a predetermined value, the contact piece 410 in the pressure switch assembly 400 is connected to the terminal and electrically connected to the main control board. The board feedback signal to the vacuum pump 22 to stop the vacuum pump 22 from evacuating the gas in the container. At this time, if the user wants to perform the pressure relief operation on the gas in the container, he only needs to push the rod body 310 toward the inside of the pressure relief cavity 101. At this time, the movement of the rod body 310 drives the seal ring 303, so that the seal ring 303 and the pressure release There is a gap between the bottom walls of the cavity 101, and the outside air passes through the pressure relief port 110, and then enters the pressure relief cavity 101 through the gap between the seal ring 303 and the bottom wall of the pressure relief cavity 101, and then communicates with the pressure measurement cavity 102 and the pressure The interface 210 communicates with the inside of the container, and achieves a pressure relief effect.

另外，可以理解的是，在泄压过程中，实现了外界大气与泄压腔101和测压腔102气压相同的效果，则测压腔102内的密封罩500不再受大气压力的作用，进而实现恢复形变的效果，从而接触片410也随密封罩500恢复至最初状态，即接触片410与接线插针420之间断开的状态。In addition, it can be understood that during the pressure relief process, the same effect of the external atmosphere as the pressure of the pressure relief chamber 101 and the pressure measuring chamber 102 is achieved, the sealing cover 500 in the pressure measuring chamber 102 is no longer affected by the atmospheric pressure. Furthermore, the effect of restoring deformation is achieved, so that the contact piece 410 also returns to the original state with the sealing cover 500, that is, the state where the contact piece 410 and the connection pin 420 are disconnected.

This arrangement can make the top wall and the bottom wall of the mounting groove 311 have a limiting effect on the seal ring 303 and prevent the seal ring 303 from falling off the rod body 310.

当然，在其他实施例中，密封圈303与杆本体310可通过过盈配合的方式连接，以保证密封圈303与杆本体310运动的一致性。Of course, in other embodiments, the seal ring 303 and the rod body 310 may be connected by an interference fit to ensure the consistency of the movement of the seal ring 303 and the rod body 310.
