Description

Technical Field

[0001] The utility model belongs to the technical field of switches, and in particular relates to a switch execution module with current detection effect. Background Art

[0002] With the continuous development of smart home technology, users are constantly updating their home electricity control to intelligent and automated methods. In this process, the emergence of smart home electronic switches has become an indispensable and important part of the field of smart home technology. Existing smart electronic switches usually use switch execution modules to achieve control, which can be used in scenarios such as smart homes, smart offices, smart hotels, and smart factories to achieve intelligent control of electrical switches. The switch execution module can control the switch of electrical appliances through a variety of methods such as physical switches, wireless remote controls, and mobile phone apps, thereby achieving intelligent control of electrical appliances.

[0003] As people's living standards improve, various household appliances have increased, but most household appliances do not have the ability to detect current to prevent electrical fires. Users usually install air switches in the main distribution box to prevent electrical fires, but they cannot perform circuit detection on the electrical equipment used to monitor whether the user's equipment has leakage, short circuit and other problems. This leads to a high probability that other appliances will be implicated and affect their normal use once an appliance connected to the same socket or switch fails. If a short circuit occurs, if the short circuit position contacts the outer casing of an appliance, this will cause leakage of the appliance. The leakage current value of this small appliance is small, and usually does not cause the air switch to react, which will cause certain safety hazards. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a switch execution module with current detection effect, which solves the problem that the existing household appliances cannot timely detect and prevent safety hazards when electrical faults occur.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a switch execution module with current detection effect, including a shell and a control board and a plurality of relays installed in the shell, the relays are electrically connected to the load electrical appliances, a central processing chip, a current detection chip and a voltage detection chip are arranged in the control board, the central processing chip and the relays, the current detection chip and the voltage detection chip, the current detection chip is used to detect the current loop conditions of the plurality of relays, the voltage detection chip is used to detect the voltage of the relay circuit, and the central processing chip controls the on and off of the relay circuit according to the detection results of the current detection chip and the voltage detection chip.

[0007] As a preferred technical solution of the utility model, the alarm module is composed of a buzzer and an alarm light.

[0008] As a preferred technical solution of the utility model, a scene holding module is also provided in the control panel, and the scene holding module is electrically connected to the central processing chip, and the central processing chip transmits the operating data of the relay to the scene holding module for storage.

[0009] As a preferred technical solution of the utility model, a plurality of buttons are arranged on the outer surface of the housing, and the plurality of buttons are arranged in a one-to-one correspondence with the plurality of relays.

[0010] As a preferred technical solution of the utility model, a communication module and a temperature detection module are electrically connected in the control board. The temperature detection module is used to detect the temperature of the relay circuit and transmit the detection result to the central processing chip. The central processing chip exchanges data with the user's mobile phone client through the communication module.

[0011] The beneficial effects of the utility model are as follows: during the use of the electrical appliance, the electrical connection needs to be completed through the switch execution module. By arranging a current detection chip and a voltage detection chip in the control board in the switch execution module, the current detection chip and the voltage detection chip are used to detect the circuit conditions of each relay connected to the electrical appliance. When the circuit current and voltage of a certain relay are abnormal, the central processing chip can cut off the circuit of the relay, thereby reducing the damage to other electrical appliances, and solving the problem that the existing household appliances cannot timely discover and prevent safety hazards when electrical failures occur.

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] See also Figure 1-2 The present embodiment provides a switch execution module with current detection effect, including a housing 1 and a control board 2 and a plurality of relays 3 installed in the housing 1. The control board 2 is provided with a central processing chip, a current detection chip and a voltage detection chip. In the process of using an electrical appliance, it is usually necessary to electrically connect the electrical appliance to a switch or a socket. In some scenarios where intelligent control is required, the switch execution module is usually used to connect the electrical appliances such as lamps, and the connection method of these electrical appliances is to connect the electrical appliances to the relays 3 through wires. Therefore, when each relay 3 is connected to the electrical appliance and starts to be used, the current detection chip and the voltage detection chip in the control board 2 are used to detect the current and voltage of the circuit loop of each relay 3. When the current detection chip and the voltage detection chip detect an abnormality in the circuit loop of a certain relay 3, and the abnormal value exceeds the set threshold value, the detection result is transmitted to the central processing chip, and the central processing chip cuts off the circuit of the relay 3, thereby avoiding affecting the use of other relays 3 and avoiding leakage, etc., thereby reducing the occurrence of safety hazards.

[0019] The detection of the current detection chip and the voltage detection chip can be completed by using current and voltage sensors. Meanwhile, the current and voltage detection of the circuit is a common prior art and will not be elaborated in detail in this application.

[0020] When the central processing chip cuts off the circuit of the relay 3 through the detection results of the current detection chip and the voltage detection chip, the load electrical appliance or circuit connected to the relay 3 needs to be repaired in time to avoid affecting normal use. Therefore, in this embodiment, an alarm module is also provided in the control board 2. When the central processing chip cuts off the circuit of a certain relay 3, the alarm module will issue an alarm after receiving the cut-off signal to remind the user to check in time whether the circuit itself is damaged or the fault is caused by the electrical appliance, so as to perform maintenance faster and avoid affecting the user's normal experience of using the electrical appliance.

[0021] After the circuit of relay 3 is cut off, in order to remind the user to check in time to prevent greater damage, in one embodiment, the alarm module consists of a buzzer and an alarm light. This is because when the detection results of the current detection chip and the voltage detection chip are abnormal, it may be due to a short circuit in the electrical appliance, which is very likely to cause an electrical fire. If the user cannot be reminded in the first time, it is very likely to cause greater losses. Therefore, the buzzer alarm and the light indication of the alarm light are used to remind the user to check in time to avoid greater losses. When the user has completed the inspection, the buzzer and the alarm light can be manually turned off to avoid the noise affecting other users.

[0022] In the process of using smart home, it is usually necessary to have specific switching requirements for each electrical appliance, such as the switching time of the induction light, the cleaning time of the sweeping robot, etc. The use logic of these appliances is set by the user according to the actual use needs. Once an appliance fails, it needs to be reset when it is replaced with a new appliance, which will affect the user's experience. Therefore, in order to reduce the need to re-set the logical functions of the replaced appliances, in one embodiment, a scene holding module is also provided in the control board 2. When the user determines the use logic of the appliance, the set data is stored through the scene holding module. When the user makes a better use of the same appliance, the scene holding module can be reapplied to the appliance through the central processing chip, reducing the steps that need to be re-set and improving the user's experience.

[0023] In order to more conveniently complete the processing and control of each function, in one embodiment, a plurality of buttons 4 are provided on the outer surface of the housing 1, and the plurality of buttons 4 are provided in one-to-one correspondence with the plurality of relays 3. By providing a plurality of buttons 4 on the outer surface of the housing 1, these buttons 4 are provided in one-to-one correspondence with the corresponding relays 3, so as to realize the convenience of function control. Specifically, when the user presses a certain button 4, the control circuit board will receive the input signal from the corresponding button 4, calculate the task to be performed through the internal processing logic, and output the control signal through the relay 3. In this way, the user can directly control the switch, adjustment and other functions of the device through the button 4 without having to perform cumbersome operations.

[0024] However, if the user is not at home and a detection failure occurs at this time, the user cannot check the electrical appliances and circuits in the first time. Once a fire occurs due to a short circuit, since no one is watching, the user can only wait for the fire to expand and produce odor or smoke for neighbors to find out, and at this time a large loss has already been caused. Therefore, in order to better prevent, in one embodiment, a communication module and a temperature detection module are also provided in the control board 2. The temperature detection module is used to detect the temperature of the relay 3 circuit. Once the temperature detection module detects that the temperature of the relay 3 circuit rises due to a short circuit, the temperature detection module will transmit the data to the central processing chip, and the central processing chip will transmit the data to the user's mobile client through the communication module to remind the user, so that the user can promptly notify neighbors, landlords or properties to help check, thereby reducing the occurrence of safety hazards and reducing losses.

[0025] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
