Description
Technical field
The present invention relates to sensor technical fields, and in particular to a kind of pressure sensor.
Background technique
With the rapid development that science and technology is with rapid changepl. never-ending changes and improvements, intelligentized portable electronic device gradually comes into vogue, example
Such as smart phone, Intelligent bracelet, intelligence on hand, tablet computer.User is intelligentized in constantly pursuit portable electronic device
Meanwhile what is more focused on is that portable electronic device is needed to experience with colourful user experience.It is more and more at present
Pressure sensor is placed in portable electronic device by manufacturer, and the sensor for usually testing pressure is strain transducer, still
The measurement accuracy of strain gauge is low.
The MEMS pressure sensor provided in the prior art generally all includes MEMS pressure sensor to improve measurement accuracy
Chip and asic chip.However, the heat dissipation performance of existing MEMS pressure sensor is bad, it is saturating to cannot achieve real-time internal-external portion
Gas influences the performance of sensor.
Therefore, it is necessary to provide the new pressure sensor of one kind to solve the above problems.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of baroceptor, solves the heat dissipation of pressure sensor
Problem.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of pressure sensor, including lid and substrate, the lid and substrate surround accommodating space；The accommodating space
Interior, IC chip and pressure sensor chip is arranged in interval side by side on substrate；The substrate, IC chip and pressure
Sensor chip realizes the electrical connection between three by gold thread；The lid includes roof and side wall, and the roof includes upper
The metal mesh and filter cotton of lower setting.
Further, the filter cotton is synthetic fibers filter cotton, non-woven fabrics filter cotton, glass fiber filter cotton, activity
Charcoal filter cotton.
Further, the mesh size of the metal mesh is 1mm-1.5mm.
Further, the size of the metal mesh and the size of roof are identical.
Further, the size of the metal mesh is less than the size of roof.
Further, detachable connection method is used between the metal mesh filter cotton and lid.
The utility model has the advantages that metal mesh is arranged on roof of the invention, and filter cotton is arranged for ventilating, under metal mesh for filtering
Dust or sundries can make that ventilation and cooling and blocks dust or sundries is kept to enter lid pollution electronic device in lid.
Detachable connection method is used between metal mesh, filter cotton and lid, facilitates and metal mesh, filter cotton are removed into cleaning.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Figure label: 1, lid；2, substrate；3, filter cotton；4, IC chip；5, pressure sensor chip；6, golden
Line；7, through-hole；8, accommodating space.
Specific embodiment
Structure and the course of work of the invention are described further with reference to the accompanying drawing.
As shown in Figure 1, the present invention provides a kind of pressure sensor, including lid 1 and substrate 2, the lid 1 and substrate 2
Surround accommodating space 8；In the accommodating space 3, IC chip 4 and pressure sensor core is arranged in interval side by side on substrate 2
Piece 5；The substrate 2, IC chip 4 and pressure sensor chip 5 realize the electrical connection between three by gold thread 6；Institute
Stating lid 1 includes roof and side wall, and the roof includes metal mesh 7 and filter cotton 3 setting up and down.
Filter cotton 3 can be in synthetic fibers filter cotton, non-woven fabrics filter cotton, glass fiber filter cotton, active carbon filter cotton
It is any.
The mesh size of metal mesh 7 is 1mm-1.5mm.
The size of metal mesh 7 can be identical as the size of roof, is also possible to a part of roof.The size and gold of filter cotton
The size for belonging to net 7 is identical.
The operation principle of the present invention is that sensor outside air enters in sensor shell body from metal mesh 7, through 3 mistake of filter cotton
The sundries in air is filtered, temperature in sensor is reduced.Using between metal mesh 7 and filter cotton 3 and shell sensor housing can
Disassembly mode, convenient for metal mesh 7 and filter screen 3 are removed cleaning.
Those skilled in the art can understand that unless otherwise defined, all terms used herein (including skill
Art term and scientific term) there is meaning identical with the general understanding of those of ordinary skill in fields of the present invention.Also
It should be understood that those terms such as defined in the general dictionary should be understood that have in the context of the prior art
The consistent meaning of meaning will not be explained in an idealized or overly formal meaning and unless defined as here.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not limited to this hair the foregoing is merely a specific embodiment of the invention
Bright, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
