Abstract
The invention relates to a low-cost negative-pressure control structure which comprises a storage tank body. A cover body is arranged on the upper side of the tank body and comprises an upper cover and a lower cover, a cavity is formed between the upper cover and the lower cover, a motor switch is fixedly arranged on the upper cover in the cavity, a moving contact and a stationary contact are arranged at the bottom of the motor switch, a tubular column and a vacuum pump are arranged on the lower cover in the cavity, one end of the tubular column is sleeved with a silica gel ball, an inner cavity of the silica gel ball is communicated with the inside of the tank body through the tubular column, the silica gel ball is located under an elastic shifting piece, the top end of the silica gel ball is in contact with the moving contact, and the vacuum pump is communicated with the inside and outside of the tank body through an exhaust pipe and is in lead connection with the motor switch. The low-cost negative-pressure control structure jacks the moving contact to be rightly in contact with the stationary contact by utilizing the silica gel ball and the elasticity of the silica gel ball itself, further a circuit is turned on to enable the vacuum pump to suck out air in a storage device, the purpose of product preservation can be achieved, and the structure is simple in structure, does not need MCU control and facilitates reduction of the product cost.
Description
Technical field
The present invention relates to negative pressure control technology field, particularly a kind of low cost vacuum cavitations structure.
Background technology
The utilization of negative pressure is very general, and people usually make certain segment space occur negative pressure state, and ubiquitous barometric pressure just can be utilized for our effect.Such as, when people breathe, there is negative pressure when lung is in expansion state, inside and outside lung, define pressure difference fresh air be just pressed in lung.
Have a variety of preservation device on the market now, use dry storage battery to carry out opening the light of control convenience, battery case place makes vacuum mainframe part not wash, and can not reach clean clean hygiene. fresh-keeping effect is had a great impact.And device inner structure has the air pressure detection valve detecting negative pressure close and provide signal to open the effect of switch to control desk IC, wherein air pressure detection valve is expensive, also needs to coordinate MCU to control, and is difficult to reduce cost of product.
For this reason, we propose a kind of low cost vacuum cavitations structure and solve the problems referred to above.
Summary of the invention
The object of the invention is a kind of low cost vacuum cavitations structure proposed to solve background technology.
To achieve these goals, present invention employs following technical scheme:
A kind of low cost vacuum cavitations structure, comprise storage tank tank body, the upside of described tank body is provided with lid, seal ring is provided with between described lid and tank body, described lid comprises upper cover and lower cover, and be provided with cavity between upper cover and lower cover, cover in described cavity and be fixed with motor switch, the bottom of described motor switch is provided with moving contact and static contact, cover under in described cavity and be provided with tubing string and vacuum pump, one end cover of described tubing string has silica-gel sphere, the inner chamber of described silica-gel sphere is communicated with the inside of tank body by tubing string, described silica-gel sphere is positioned at immediately below elastic plectrum, and the top of silica-gel sphere contacts with moving contact, described vacuum pump is communicated with inside and outside tank body by freeing pipe, and vacuum pump is connected by wire with motor switch.
On the basis of technique scheme, following further technical scheme can be had:
The top of described lid is provided with circuit general switch.
Described upper cover is hinged on down and covers, and by buckle pretension, is provided with collision mat between described upper cover and lower cover.
Described moving contact adopts elastic copper sheet.
The outlet of described freeing pipe is provided with Air Filter.
The present invention, by the silica-gel sphere arranged, utilizes silica-gel sphere self to have elasticity, by moving contact jack-up, just contact with static contact, and then connection circuit, make vacuum pump work, air in memory storage is extracted out, the object of fresh products can be reached, by changing silica-gel sphere soft durometer, can control the negative pressure value size of cryopreservation device, this structure is simple, control without the need for MCU, favourable reduces cost of product.
Accompanying drawing explanation
Fig. 1 is a kind of low cost vacuum cavitations structure structural representation that the present invention proposes;
Fig. 2 is motor switch and the silica-gel sphere schematic diagram of a kind of low cost vacuum cavitations structure that the present invention proposes.
1 tank body, 2 lids, 3 upper covers, 4 lower covers, 5 cavitys, 6 vacuum pumps, 7 motor switch, 8 moving contacts, 9 static contacts, 10 tubing strings, 11 silica-gel spheres, 12 freeing pipes, 13 seal rings.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described.
With reference to Fig. 1-2, a kind of low cost vacuum cavitations structure, comprise storage tank tank body 1, the upside of tank body 1 is provided with lid 2, seal ring 13 is provided with between lid 2 and tank body 1, lid 2 comprises upper cover 3 and lower cover 4, and be provided with cavity 5 between upper cover 3 and lower cover 4, upper cover 3 is hinged on lower cover 4, and by buckle pretension, collision mat is provided with between upper cover 3 and lower cover 4, when preventing from cleaning, water enters in lid 2, cause short circuit, upper cover 3 in cavity 5 is fixed with motor switch 7, the bottom of motor switch 7 is provided with moving contact 8 and static contact 9, moving contact 8 adopts elastic copper sheet, lower cover 4 in cavity 5 is provided with tubing string 10 and vacuum pump 6, one end cover of tubing string 10 has silica-gel sphere 11, the inner chamber of silica-gel sphere 11 is communicated with the inside of tank body 1 by tubing string 10, silica-gel sphere 11 is positioned at immediately below elastic plectrum 8, and the top of silica-gel sphere 11 contacts with moving contact 8, vacuum pump 6 is communicated with inside and outside tank body 1 by freeing pipe 12, the outlet of freeing pipe 12 is provided with Air Filter, prevent dust from entering in vacuum pump 6, cause breakdown of equipment, vacuum pump 6 is connected by wire with motor switch 7, the top of lid 2 is provided with circuit general switch.
Lid 2-in-1 upper after, device for opening main supply switch, because silica-gel sphere 11 self has elasticity, by moving contact 8 jack-up, just contact with static contact 9, now vacuum pump 6 is started working, air in storage tank tank body 1 is extracted out, to reach fresh-keeping object, when in tank body 1, negative pressure reaches certain value, silica-gel sphere is subject to negative pressure impact in container and is out of shape, moving contact 8 and static contact 9 are disconnected, and vacuum pump 6 quits work, in addition, by changing silica-gel sphere soft durometer, can the negative pressure value size of control store tank 1.
