After passing through the first through hole 1511, the direction probe 110 contacts with the gas to be measured, and the gas to be measured can be collected. The housing includes an accommodating space for accommodating the connection pipe 130 and the processing component, so as to accommodate the connection pipe 130 and the processing component, and protect and fix the connection pipe 130 and the processing component.
Alternatively, the processing unit 143 may be, but is not limited to, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), or the like. The fillets of the air pressure sensor 141 and the processing unit 143 may be welded together to achieve connection of the processing unit 143 to the air pressure sensor 141. The processing unit 143 may be secured within the housing by other means, such as by mating with other fasteners.
Referring to fig. 3 again, fig. 3 is a block diagram of an air pressure measuring device 100 according to an embodiment of the invention. The air pressure measuring device 100 may further include a connection unit 161. The connection unit 161 is electrically connected to the processing unit 143, and the processing unit 143 may send the measured gas pressure information of the gas to be measured to other devices through the connection unit 161.

The baffle 165 is configured to block the second through hole 1513, thereby fixing and protecting the device in the first housing 151.
Optionally, the size of the baffle 165 is matched with the size of the second through hole 1513, for example, the size of the baffle 165 is slightly smaller than the size of the second through hole 1513, and the baffle 165 is disposed at the second through hole 1513 and contacts with the inner side surface of the first housing 151, so as to shield the second through hole 1513. The baffle 165 may also be coupled to the end of the first housing 151 adjacent the second port 1513 in an end-to-end manner using a seal (e.g., a gasket). It will be understood, of course, that the second through hole 1513 may be blocked by the baffle 165 in other manners.
In this embodiment, the housing may further include a second housing 152, where the second housing 152 is a hollow structure with two open ends, and the second housing 152 is connected to the first housing 151. One end of the connection unit 161 may pass through the baffle 165 to be electrically connected with the processing unit 143, and the other end protrudes toward the second housing 152 with respect to the baffle 165, i.e., the other end extends in a direction away from the baffle 165 within the second housing 152. Since the two ends of the second housing 152 are respectively provided with a first opening and a second opening, the first opening is close to the first housing 151, and therefore the connection unit 161 can be electrically connected with other devices through the second opening. In addition, the second housing 152 may also protect the connection unit 161 from damage due to direct collision with other objects.
Optionally, the first housing 151 may include a mounting portion 1515, and a portion of the first housing 151 adjacent to the second housing 152 is the mounting portion 1515. The caliber of the mounting portion 1515 is matched with the caliber of the first opening, so that the mounting portion 1515 can be inserted into the second housing 152, thereby realizing the connection of the first housing 151 and the second housing 152 through the cooperation of the mounting portion 1515 and the first opening.
Alternatively, in one implementation of this embodiment, the air pressure collecting tube 111 is integrally formed with the connecting tube 130, and one end is used to obtain the air to be measured, and the other end is used to communicate with the measuring port 1411 of the air pressure sensor 141, that is, one end of one measuring tube is in contact with the outside, and one end is in communication with the measuring port 1411.
Alternatively, in another implementation of the present embodiment, the pneumatic collection tube 111 and the connecting tube 130 may be separate two devices, and the pneumatic collection tube 111 may be sleeved, welded or otherwise placed in communication with the connecting tube 130.
Referring to fig. 5 in combination, fig. 5 is a third schematic structural diagram of an air pressure measuring device 100 according to an embodiment of the invention. The air pressure measurement device 100 may also include a connector 120. The connector 120 is fixed in the first housing 151, and the connector 120 may include a transmission channel 121, where the transmission channel 121 communicates with the pneumatic collecting tube 111 and the connecting tube 130. Thus, the air pressure collecting pipe 111, the transmission channel 121 and the connecting pipe 130 form an air pressure measuring channel, and one measuring interface 1411 is communicated with the air pressure measuring channel, so that the processing unit 143 can calculate the air pressure of the air to be measured.
Referring to fig. 6 in combination, fig. 6 is a schematic structural diagram of the connector 120 in fig. 5. The opposite sides of the connector 120 are provided with a first communication port 1211 and a second communication port 1212. The first communication port 1211, the second communication port 1212, and the passage provided inside the connection head 120 constitute the transmission passage 121. Alternatively, the line of the first communication port 1211 and the second communication port 1212 may be perpendicular or not perpendicular to the side surface on which the first communication port 1211 is disposed.
In the embodiment of the present embodiment, the connection mode between the connector 120 and the pneumatic collection tube 111 and the connection tube 130 may be, but is not limited to, welding, plugging, connection by a sealing member, or the like. For example, when the plugging method is adopted, the air pressure collecting pipe 111 may be plugged into the first communication port 1211, and the connecting pipe 130 may be plugged into the second communication port 1212, thereby realizing the connection between the air pressure collecting pipe 111 and the connecting pipe 130 and the connecting head 120.
Optionally, the direction probe 110 may further include a probe housing 113. The opposite ends of the probe housing 113 are respectively provided with a third through hole and a fourth through hole. Wherein the fourth through hole is provided at a side of the probe housing 113 close to the first case 151. One end of the air pressure collecting pipe 111 communicates with the third through hole to collect the air to be measured. The other end of the pneumatic collection tube 111 communicates with the transfer passage 121 through the fourth through hole. Thus, a gas to be measured is obtained.
In the embodiment of the present embodiment, the air pressure collecting pipe 111, the transmission channel 121, the connection pipe 130, and the air pressure sensor 141 may be one or more.
Referring to fig. 2 to 3 and fig. 5 to 6 again, the plurality of air pressure collecting pipes 111, the plurality of transmission channels 121, the plurality of connecting pipes 130 and the plurality of air pressure sensors 141 are all described. The following is a detailed description.

The plurality of transmission channels 121 may be parallel or non-parallel.
Alternatively, in order to avoid communication between the transmission channels 121 which is likely to be caused by parallel arrangement of a plurality of the transmission channels 121, or to avoid the arrangement of a plurality of the connection pipes 130, the transmission channels 121 may be arranged in a non-parallel manner. As shown in fig. 6, for two adjacent transmission channels 121, the distance between two corresponding first communication ports 1211 is smaller than the distance between two corresponding second communication ports 1212, so that the transmission channels 121 are not communicated, and a plurality of connection pipes 130 are conveniently arranged.
Alternatively, the number of connecting tubes 130 is at least the same as the number of pneumatic collection tubes 111.
The air pressure collecting pipes 111, the connecting pipes 130 and the transmission channels 121 are in one-to-one correspondence to form different air channels. For example, there are pneumatic collecting tubes a1, a2, transfer passages b1, b2, connecting tubes c1, c2, pneumatic pressure sensor A, B, gas passage 1 is constituted by a1-b1-c1, and gas passage 1 is constituted by a2-b2-c 2. The measuring interface of the air pressure sensor A is communicated with the air channel 1, and the measuring interface of the air pressure sensor B is communicated with the air channel 2.
