Abstract
A tea box capable of being stored at negative pressure comprises a box body, wherein the box body is provided with an upward opening, the opening of the box body is connected with an upper cover in a sealed mode, the inner diameter of the cross section of the upper cover is equal to the inner diameter of the cross section of the box body, the top wall of the upper cover is provided with an operation opening, a pressure adjusting plate is connected with the inside of the upper cover in an up-down sliding mode, the diameter of the pressure adjusting plate is larger than that of the operation opening, the pressure adjusting plate and the side wall of the upper cover are matched in a sealed and sliding mode, the upper portion of the pressure adjusting plate is fixedly connected with a handle, the periphery of the side wall of the pressure adjusting plate is fixedly connected with a sealing ring, the sealing ring and the side wall of the upper cover are matched in a sealed and sliding mode, the pressure adjusting plate is connected with a one-way valve in a sealed mode, the upper portion of the bottom wall of the box body is fixedly connected with a spring, and the upper end of the spring abuts against the lower portion of the pressure adjusting plate. Due to the fact that key components are connected in a sealed mode, the upper cover is connected with the opening of the box body in a sealed mode after tea is taken, at the time, pressure inside the box body and pressure outside the box body are equal, the pressure adjusting plate is pressed downward through the operation opening so that the pressure adjusting plate can move downward along the side wall of the upper cover, and the spring is compressed.
Description
Technical field
The utility model relates to a kind of tea caddy, but relates in particular to the tea caddy that a kind of negative pressure is preserved.
Background technology
Tea is the drink in people's daily life, and tealeaves is people's life necessary article,, if tealeaves is exposed in air for a long time, can oxidizedly go bad, and also can make moist, and the bubble effect is infused in impact.Therefore people are placed on tealeaves in tea caddy and store, and still, in storage and taking the process of tealeaves, the air pressure of box body inside is with extraneous identical, and its fresh-keeping effect is also bad.
The utility model content
The utility model is for deficiency, but a kind of result of use tea caddy that good negative pressure is preserved is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
But the tea caddy that a kind of negative pressure is preserved, comprise box body, box body is with the opening that makes progress, the airtight upper cover that is connected with of the opening part of box body, the cross sectional inner diameter equal and opposite in direction of the cross sectional inner diameter of upper cover and box body, it is characterized in that, the roof of upper cover has gathering hole, slide up and down in upper cover and be connected with regulator board, the diameter of regulator board is greater than the diameter of gathering hole, and regulator board and the airtight bearing fit of upper cover sidewall, be fixedly connected with squeezing handle above regulator board, the airtight seal ring that is fixedly connected with in regulator board sidewall border, seal ring and the airtight bearing fit of upper cover sidewall; The airtight check valve that is connected with on regulator board; Be fixedly connected with spring above the diapire of box body, the upper end of spring withstands on below regulator board.
all airtight connections between each key components in the utility model, take after tealeaves the airtight opening part that is connected to box body of upper cover, at this moment, the inside and outside air pressure of box body equates, press regulator board downwards by gathering hole, regulator board moves downward along the upper cover sidewall, also can continue to move downward along box side wall, spring is compressed, under the effect of check valve, gas in box body outwards discharges, therefore the inside and outside air pressure of box body also equates, then unclamp regulator board, under the application force of spring, regulator board is by the jack-up that makes progress, no longer include air and enter box body inside, therefore the air pressure in box body is negative pressure, the content of oxygen diminishes, the humidity of air also changes to some extent, tealeaves stores just not perishable under this environment, so good refreshing effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing:
1, squeezing handle; 2, gathering hole; 3, upper cover; 4, seal ring; 5, regulator board; 6, spring; 7, box body; 8, check valve.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, not is used for limiting scope of the present utility model.
as shown in Figure 1, but the tea caddy that a kind of negative pressure is preserved, comprise box body 7, box body 7 is with the opening that makes progress, the airtight upper cover 3 that is connected with of the opening part of box body 7, the cross sectional inner diameter equal and opposite in direction of the cross sectional inner diameter of upper cover 3 and box body 7, the roof of upper cover 3 has gathering hole 2, slide up and down in upper cover 3 and be connected with regulator board 5, the diameter of regulator board 5 is greater than the diameter of gathering hole 2, regulator board 5 and the upper cover 3 airtight bearing fits of sidewall, be fixedly connected with squeezing handle 1 above regulator board 5, the airtight seal ring 4 that is fixedly connected with in regulator board 5 sidewall borders, seal ring 4 and the upper cover 3 airtight bearing fits of sidewall, the airtight check valve 8 that is connected with on regulator board 5, be fixedly connected with spring 6 above the diapire of box body 7, the upper end of spring 6 withstands on below regulator board 5.
