Description

An infrared welcome and alarm dual-purpose welcome device

technical field

The utility model relates to the field of welcome devices, in particular to an infrared welcome device with the function of anti-theft alarm at night.

Background technique

The welcome device, also known as the induction doorbell, can announce the welcome voice as soon as the customer enters the door, so as to achieve the dual functions of reminding the clerk that someone is entering the store and welcoming guests. The existing welcome device mainly includes two structures: light induction type and infrared induction type. Among them, the light-sensing welcome device uses the light reflected by the human body, the photoresistor obtains a sufficiently large change of light, and the circuit generates a changing current to trigger the circuit. The sensitivity is related to the reflectivity of the object. Since the light-sensing type is related to light, the false alarm rate is relatively high. , and are not suitable for use in dark conditions. The infrared induction welcome device senses the radiation generated by the human body, and has a good detection effect and is widely used. But existing welcome device all does not possess the anti-theft alarm function at night when in use. This requires the user to configure an additional night alarm, which increases the cost of opening a store.

At the same time, most of the existing welcome devices sound: Ding Dong, hello, welcome, etc. All shops use similar ring tones, which lack individuality and characteristics, and the existing welcome devices do not have With the recording function, it is not possible to record personalized ringtones or ringtones that match store merchandise.

Contents of the invention

The purpose of this utility model is to provide an infrared welcome and alarm dual-purpose greeter. By setting a reasonable structure, it can realize the functions of daily welcome and night alarm. demand and reduce equipment costs.

In order to achieve the above purpose, the utility model can be realized through the following technical solutions: an infrared welcome and alarm dual-purpose welcome device, including a shell, an infrared sensor, a loudspeaker and a power supply are installed on the shell, and a function switching switch is also installed on the shell. A circuit board is installed inside, and a control chip and an alarm prompt module are arranged on the circuit board, and the control chip is respectively connected with a function switching switch, an infrared sensor, a power supply and an alarm prompt module.

A recorder and a recording button are installed on the casing, and a memory chip is arranged on the circuit board, and the recorder and the recording button are respectively connected with the memory chip.

A light-sensitive sensor switch is installed on the shell, and the light-sensitive sensor switch is connected with the control chip.

The beneficial effect of the utility model is that: it can solve the deficiencies in the known technology; the infrared sensor is used, and an alarm prompt module is built in, so that the user can switch the function when the welcome device is used as an alarm device, and use the infrared sensor to , for the purpose of anti-theft, with various functions and easy to use; it is equipped with a recorder, which can record personalized and multilingual welcome voices, which is easy to use and can make the store image more distinctive; it can use photosensitive sensors to achieve anti-theft The automatic activation of the function prevents loss caused by the user forgetting to switch the function of the welcome device at night, and improves the effect of safety and anti-theft; the structure is simple and reasonable, etc.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

The infrared welcome and alarm dual-purpose welcome device described in the utility model has a main structure including a shell 2, which can be a metal shell or a high-strength plastic shell 2, and the high-strength plastic shell 2 is preferably used in order to reduce costs. An infrared sensor 5, a loudspeaker 1 and a power supply are installed on the housing 2, and the infrared sensor 5 can sense people entering the store, and send a welcome message or an alarm message through the loudspeaker 1. The power supply can be powered by a wired wire or a battery, preferably a battery, which does not require complicated power supply lines and reduces installation costs. Also installed function switching switch 6 on the described shell 2, circuit board is installed in the shell 2, and control chip and warning prompt module are set on the circuit board, and control chip is respectively connected with function switching switch 6, infrared sensor 5, power supply and warning prompt module respectively. connect. Through the function switching switch 6, the switching between the welcoming function and the alarm prompting function can be realized.

The further technical feature of the utility model is: a recorder 8 and a recording button 7 are installed on the shell 2, a memory chip is arranged on the circuit board, and the recorder 8 and the record button 7 are respectively connected with the memory chip. This embodiment can realize the recording of personalized welcome voices, improve the attractiveness of the store to customers, and can record welcome voices in different languages, which is very convenient to use.

In order to prevent the user from forgetting to press the function switching switch 6 to switch the function, the housing 2 is preferably equipped with a photosensitive switch 4, which is connected to the control chip. The photosensitive switch 4 described in this embodiment can sense the intensity of light in the store, and when the store is closed, it can automatically activate the anti-theft function of the present utility model, preventing users from forgetting to switch the function of the welcome device at night, and ensuring the safety of the store.

When the utility model is in use, when the function switching switch 6 is located at the welcome function button, the infrared sensor 5 automatically detects the customers entering the store, and controls the loudspeaker 1 through the control chip to send the recorded personalized welcome sound, which plays a good role. The effect of welcoming guests and attracting customers; when the function switching switch 6 is located at the alarm function button, the control chip controls the alarm prompt module to start, and when an illegal intruder breaks into the store, the infrared sensor 5 automatically detects the shoplifter, and through the control The chip and the alarm prompting module control the loudspeaker 1 to send a very ear-piercing alarm sound together to prevent property damage.
