Abstract
A switching system for a greenhouse thermostat comprises an outer cover and a switching system, wherein a hollow exhaust chamber is embedded in the outer wall of the outer cover, the switching system and a spiral elastic rod are mounted in the outer cover, a strip-shaped bar is arranged in the spiral elastic rod, one end of the strip-shaped bar is contacted with the switching system, a through slot is formed in the outer wall of the upper part of the switching system, an outward tube is arranged below the through slot, an upper tube and a compressed reset part are mounted in the switching system, a bracket is mounted in a hollow chamber in the bottom of the switching system, an input end is erected at the bottom of the bracket, a round body is embedded in the bracket, and an elastic buffer is attached to the bottom of the round body. Defects of disordered output power, energy output loss and electricity waste caused by instable operation and disordered sound field of the greenhouse thermostat due to the hard start and stop mode are effectively overcome.
Description
Technical field
The invention belongs to greenhouse technology field, be specifically related to the switching system of a kind of greenhouse thermosistor.
Background technology
The cylinder group of constant output is all generally installed in current greenhouse thermosistor, the cylinder group formal standard of this constant output is convenient, above not for the switch of such cylinder group, such cylinder can only meet the constant output under the stable displacement not having cylinder pneumatic compression devices, such constant output function singleness can only have two states: duty and halted state, cylinder startup or mute key is so just only needed to accomplish, so the mode that rigid like this startup stops just forming the fluctuation of service of greenhouse thermosistor, and produce disorderly sound field, cause the output power of greenhouse thermosistor disorderly, off-energy exports and takes electricity.
Summary of the invention
The switching system that the invention provides a kind of greenhouse thermosistor comprises the same switching system of outer cover, the outer wall of outer cover is fitted together to the discharge air chamber of hollow, switching system and spiral fashion elastic rod are installed in outer cover, strip thick stick is set in spiral fashion elastic rod, one of strip thick stick contacts with switching system, switching system upper outer wall with through slot, the below of through slot is with outer conductive pipe, upper tube and compression return unit are installed in switching system, in the lower hollow room of switching system, support is installed, the bottom shelf of support has input end, round is embedded in support, elastic buffer is set up bottom round.Efficiently avoid mode that rigid startup stops just can form the fluctuation of service of greenhouse thermosistor and produce disorderly sound field, cause the defect that the output power of greenhouse thermosistor is disorderly, off-energy exports and expense is electric.
For achieving the above object, technical scheme of the present invention is:
The switching system of a kind of greenhouse thermosistor, comprise outer cover 1 with switching system 2, the outer wall of outer cover 1 is fitted together to the discharge air chamber 9 of hollow, switching system 2 and spiral fashion elastic rod 3 are installed in outer cover 1, strip thick stick 4 is set in spiral fashion elastic rod 3, one of strip thick stick 4 contacts with switching system 2, switching system 2 upper outer wall with through slot 10, the below of through slot 10 is with outer conductive pipe 11, upper tube 5 and compression return unit 12 are installed in switching system 2, in the lower hollow room of switching system 2, support 6 is installed, the bottom shelf of support 6 has input end 8, round 7 is embedded in support 6, elastic buffer 101 is set up bottom round 7.
The edge of described input end 8 is covered with baffle plate 102.
The present invention compared with prior art avoids because the regular startup of greenhouse thermosistor and the mode that stops rigid startup to stop just can form the fluctuation of service of greenhouse thermosistor and produce disorderly sound field, cause that the output power of greenhouse thermosistor is disorderly, off-energy exports and takes electric defect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the switching system of greenhouse of the present invention thermosistor.
Embodiment
Below by specific embodiment, the present invention will be further described:
As shown in Figure 1, the switching system of greenhouse thermosistor, comprise outer cover 1 with switching system 2, the outer wall of outer cover 1 is fitted together to the discharge air chamber 9 of hollow, switching system 2 and spiral fashion elastic rod 3 are installed in outer cover 1, strip thick stick 4 is set in spiral fashion elastic rod 3, one of strip thick stick 4 contacts with switching system 2, switching system 2 upper outer wall with through slot 10, the below of through slot 10 is with outer conductive pipe 11, upper tube 5 and compression return unit 12 are installed in switching system 2, in the lower hollow room of switching system 2, support 6 is installed, the bottom shelf of support 6 has input end 8, round 7 is embedded in support 6, elastic buffer 101 is set up bottom round 7.The edge of described input end 8 is covered with baffle plate 102.
Principle of work of the present invention is when the flow velocity of through slot 10 is greater than the critical value of setting, if the flow velocity of through slot 10 like this, greenhouse thermosistor just strengthens output power, spiral fashion elastic rod 3 forces down by output power pressure of inspiration(Pi) larger like this, upper tube 5 inwardly retraction, elastic buffer 101 combines larger output power and is moved towards support 6 gravity direction by round 7.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solution of the present invention content, according to technical spirit of the present invention, within the spirit and principles in the present invention, to any simple amendment that above embodiment is done, equivalent replacement and improvement etc., within the protection domain all still belonging to technical solution of the present invention.
