Problems solved by technology

A general air pressure switch is composed of a lower casing, a diaphragm, a micro switch and an upper cover, etc. From this, it can be obtained that the traditional air pressure switch is generally a mechanical transmission structure, and the air pressure switch with a mechanical transmission structure has the following problems : First, the small size and large number of parts and components lead to complicated internal structures, cumbersome processing procedures, and inconvenient operation for workers; second, no relevant waterproof measures are designed, which are easy to rust and corrode, and have a short service life; third, the mechanical transmission structure It takes a certain amount of time for the transmission, and the mechanical transmission structure needs to overcome the mutual friction between the parts during the transmission process, and the transmission efficiency is low, which leads to the unresponsiveness of the wind pressure switch and the extremely low sensitivity; Fourth, it cannot realize digital display. Changes in differential pressure cannot be observed

Embodiment 1

[0034] Embodiment one: if Figures 1 to 7 The shown electronic air pressure switch includes an integrally injection-molded housing 1, which is provided with an integrated circuit board that can detect wind pressure in real time and convert it into an electrical signal, and the integrated circuit boards are sequentially linked There are hardware button elements that can manually input and manually adjust the OFF wind pressure value and ON wind pressure value, and the air pipe assembly that can conduct the gas to be detected. The hardware button element and the air pipe assembly are installed on the housing 1 The housing 1 is provided with a wire inlet 2 connected to the inside of the housing 1. The integrated circuit board can be connected to the positive and negative poles of the power supply through the wire inlet 2. The integrated circuit board is electrically connected to the The indicator light 8 on the housing 1.

[0035] The integrated circuit board is provided with a d...

Embodiment 2

[0038] Embodiment two: if Figure 8 The shown electronic wind pressure switch includes a group of gas inlet pipes 7 for detecting wind pressure, and the structures of other components are the same as those in Embodiment 1.

[0039] Using the two technical solutions of the above-mentioned embodiment 1 and embodiment 2, the "program instructions" related to "opening and closing" can be input into the control chip, and the wind pressure pressure switch can perform parameters according to the requirements of the program after collecting the pressure value The program automatically sets the parameters for the corresponding command, and the customer does not need to adjust it. As an auxiliary function display element (such as LCD liquid crystal, LED digital) and button group and other structures, if the automatic adjustment program fails in an emergency, the control chip "Program instruction" will automatically switch to manual adjustment mode, which can be quickly trimmed without c...

Embodiment 3

[0047] Embodiment 3: An electronic air pressure switch. Compared with Embodiment 1, no display elements and hardware button elements are installed, and other components are the same as Embodiment 1, wherein the control chip does not input information about "opening and closing". "Program Instructions".

[0048] Adopting the technical solution of the third embodiment above can meet the needs of some customers. The wind pressure switch itself does not have any switching function. The main function of the product is to collect positive and negative pressure values, convert them into signals, and then output the signals to the user through physical means. The main control board of the customer, after the main control board gets the signal value, the customer can make corresponding settings on the operation panel, install it on the wall-hung boiler of the corresponding model, and then use it. The product will take the form of an indicator light during use The running status is disp...

Abstract

The invention relates to an electronic wind pressure switch which is characterized in that the electronic wind pressure switch. The switch comprises a shell which is integrally formed through injection molding, wherein an integrated circuit board is arranged in the shell, the integrated circuit board is in linkage with a hardware button element and an air pipe assembly in sequence, and the hardware button element and the air pipe assembly are both installed on the shell; the shell is provided with a wire inlet communicated with the interior of the shell, the integrated circuit board can be connected with the positive electrode and the negative electrode of a power source through the wire inlet, and the electronic wind pressure switch has the advantages of having the waterproof function, being high in sensitivity, rapid in response and high in use precision, and improving product stability and quality.

Description

technical field [0001] The invention relates to the technical field of wind pressure switches, in particular to an electronic wind pressure switch. Background technique [0002] At present, the known wind pressure switch uses air pressure to drive the diaphragm inside the switch to press down, and the closing operation is realized by pushing the micro switch by the gas pressure, so as to achieve the purpose of detecting the exhaust pressure. A general air pressure switch is composed of a lower casing, a diaphragm, a micro switch and an upper cover, etc. From this, it can be obtained that the traditional air pressure switch is generally a mechanical transmission structure, and the air pressure switch with a mechanical transmission structure has the following problems : First, the small size and large number of parts and components lead to complicated internal structures, cumbersome processing procedures, and inconvenient operation for workers; second, no relevant waterproof m...
