Abstract
The utility model relates to a liquid level detecting device, including the sensor mount pad of locating liquid level top with install in correlation formula photoelectric sensor on the sensor mount pad, be the installation of certain angle between correlation formula photoelectric sensor's transmitting terminal and the receiving terminal for the light that the transmitting terminal sent is received by the receiving terminal after the liquid level reflection of a take the altitude. Will you please the light that this liquid level detecting device adopted correlation formula photoelectric sensor's transmitting terminal to launch be detected the liquid level by receiving terminal receipt arrival and whether reach corresponding liquid level after the liquid level reflects, not only simple structure adjusts the convenience, and is stable good in addition, not limited by the container material.
Description
Technical field
The utility model is related to field of photodetection, more particularly, it relates to a kind of liquid level detector.
Background technology
Liquid level is typically all realized by sensor.Although having various level detection elements on the market at present,
Under low temperature and high relative humidity environment (such as in the full-automatic orange juice making device with refrigerating function), be easily subject to humidity of the globule or dixie cup etc. because
Element impact and to liquid level produce erroneous judgement.The stability of emission sensor is relatively good, thus is also used for level detection.But
The liquid level detector of existing employing emission sensor is usually will be relative with receiving terminal for the transmitting terminal of emission sensor
It is arranged on the both sides of container in the container containing liquid, the infrared light of transmitting terminal transmitting passes through container receiving end to receive, works as appearance
When liquid level in device reaches corresponding liquid level, will there is certain inhibition to the propagation of infrared light, it is red that receiving terminal receives
Outer optical signal will be varied from, and so just can detect whether liquid level reaches corresponding liquid level.This liquid level detector requires
Container must be made transparent material, using being restricted.
Utility model content
The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, provides a kind of stability
Liquid level detector high and that receptor material does not limit.
The utility model solves its technical problem and be employed technical scheme comprise that：A kind of liquid level detector is proposed, including
Located at sensor installation seat and the correlation photoelectric sensor being installed on described sensor installation seat of ullage, described right
Penetrate between the transmitting terminal of formula photoelectric sensor and receiving terminal and to install at an angle so that the light that sends of transmitting terminal is through certain altitude
Liquid level reflection after receiving end receive.
According in an embodiment of the present utility model, described sensor installation seat includes pedestal and downward from pedestal both sides
Two installing plates extending, the transmitting terminal of described correlation photoelectric sensor and receiving terminal are respectively arranged in described two installations
On plate.
Liquid level detector of the present utility model adopts the light of the transmitting terminal transmitting of correlation photoelectric sensor through liquid level
Can receive whether the detection liquid level that arrives reaches corresponding liquid level in receiving end after reflection, not only structure is simple, easy to adjust, and
Good stability, not receptor material restriction.
Brief description
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the structural representation of the liquid level detector of one embodiment of the utility model, illustrated therein is liquid level and reaches
Light path to position；
Fig. 2 is the schematic diagram of the light path when liquid level is not up to position for the liquid level detector shown in Fig. 1.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only in order to explain
The utility model, is not used to limit the utility model.
Fig. 1 shows the structural representation of the liquid level detector according to one embodiment of the utility model.As Fig. 1 institute
Show, this liquid level detector includes sensor installation seat 10 and correlation photoelectric sensor 20.Wherein, sensor installation seat 10 sets
It is placed in above the liquid level 40 of container 30.In specifically used, sensor installation seat 10 may be installed the container 30 within corresponding device
Overthe openings.Sensor installation seat 10 can be by pedestal 11 and two installing plates 12 and 13 extending downwardly out from pedestal 11 both sides
Constitute.Correlation photoelectric sensor 20 includes transmitting terminal 21 and receiving terminal 22, and transmitting terminal 21 and receiving terminal 22 are respectively arranged in two
On individual installing plate 12 and 13, and arrange at an angle between transmitting terminal 21 and receiving terminal 22.This angle is by the appearance needing control
Liquid level in device 30, to determine, will can make the launching light 51 that transmitting terminal 21 sends after the liquid level 40 of corresponding liquid level reflects,
Reflected light 52 can receive receiving end 22.Receiving terminal 22 receives reflected light 52, and this liquid level detector just can confirm that container 30
Interior liquid level 40 reaches corresponding liquid level.
If the liquid level 40 in container 30 is not up to corresponding liquid level, as shown in Fig. 2 the launching light 51 that transmitting terminal 21 sends is passed through
After liquid level 40 reflection, reflected light 52 is unable to receiving end 22 and receives.Receiving terminal 22 does not receive reflected light 52, and this level detection fills
Put the liquid level 40 that just can confirm that in container 30 and not yet reach corresponding liquid level.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in the utility model
Protection domain within.
Claims (2)
1. a kind of liquid level detector is it is characterised in that including located at the sensor installation seat of ullage and being installed on described
