All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.
It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a single embodiment.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 3, an embodiment of the present invention provides a test chamber for preventing water dripping, including:
a case (not shown) provided with an opening;
the box door 1 is rotatably connected with the box body and is used for opening or closing the opening; the bottom of the inner wall of the box door 1 is provided with a water chute 2, and the bottom wall of the water chute 2 is provided with a drain hole 201;
the counterweight sealing block 3 is arranged in the water chute 2, and the counterweight sealing block 3 comprises a plugging plate 301 and a plugging head 302 arranged at the lower end of the plugging plate 301; the section area of the blocking plate 301 is larger than the end surface area of the drain hole 201, and the blocking head 302 is matched with the drain hole 201; the plugging head 302 is movably arranged in the drain hole 201 in a penetrating way;
the water accumulation plate 4 is arranged on the box body and is matched with the plugging head 302;
when the box door 1 is in an open state, the counterweight sealing block 3 is in a blocking state under the action of self gravity, the blocking plate 301 is attached to the bottom wall of the water guide groove 2, the blocking head 302 is arranged in a penetrating mode for draining water, and the lower end of the blocking head 302 extends to the position below the water guide groove 2;
when the box door 1 is in a closed state, the water accumulation disc 4 is pressed against the lower end of the sealing head 302, so that the counterweight sealing block 3 is lifted, the sealing plate 301 is separated from the bottom wall of the water chute 2, and the drain hole 201 is opened.
In this embodiment, the water chute 2 may be a chute shell with an open upper end, which is disposed at the bottom of the inner wall of the box door 1 and can rotate with the box door 1. The box door 1 may be connected to an outer wall of the box body by a hinge or a hinge, and may be inserted into or removed from the opening to close or open the box body. In addition, a window 103 may be disposed on the box door 1, so that the worker can observe the inside condition of the test box through the window 103.
As shown in fig. 1, the door 1 may include a first side 101 rotatably connected to the cabinet, and a second side 102 opposite to the first side 101, and the drain hole 201 may be correspondingly disposed below the second side 102. Therefore, the counterweight sealing block 3 can be arranged at a position far away from the pivot point of the box door 1, and the situation that the box door 1 cannot be normally opened or closed due to the fact that the blocking head 302 of the counterweight sealing block 3 is clamped on the box body is avoided.
The counterweight sealing block 3 is a block, the blocking plate 301 contained therein is accommodated in the water chute 2, the cross-sectional area of the blocking plate is larger than the end surface area of the drain hole 201, and the blocking head 302 is matched with the drain hole 201. Specifically, the blocking head 302 may be a cylindrical structure formed by downward protruding of the lower surface of the blocking plate 301, and the drainage hole 201 may correspond to a circular hole. In order to allow the blocking head 302 to slide in the drain hole 201, the blocking head 302 is preferably in clearance fit with the drain hole 201. When the lower end of the blocking head 302 of the counterweight sealing block 3 is not in contact with the water collecting disc 4, the counterweight sealing block 3 falls under the action of gravity, the blocking head 302 is inserted into the drain hole 201, and the blocking plate 301 is attached to the inner wall of the water chute 2 and covers the drain hole 201, so that the drain hole 201 is blocked.
Further, the lower end of the plugging head 302 may be spherical. Thus, when the box door 1 rotates to the closed state and the spherical lower end of the blocking head 302 contacts with the water accumulation disc 4, the spherical lower end of the blocking head 302 can slide on the upper surface of the water accumulation disc 4, and then the whole counterweight sealing block 3 can be jacked up by the water accumulation disc 4, so that the drainage hole 201 is opened. Therefore, the frictional resistance between the water accumulation disc 4 and the blocking head 302 is reduced, and the balance weight sealing block 3 can be smoothly jacked up or dropped.
The water collecting disc 4 is in a disc shape with a concave middle part, the inner wall of the box door 1 is provided with a vertical dripping guide groove, and the lower end of the dripping guide groove is communicated with the water guide groove 2. Thus, when the box door 1 is opened, the condensed water formed on the inner wall of the box door 1 can flow downwards through the vertically arranged dripping guide groove and finally is gathered in the water guide groove 2. Further, in order to discharge the water gathered in the water collecting tray 4, a water outlet 401 may be disposed at the bottom of the water collecting tray 4, and the water outlet 401 communicates the water collecting tray 4 with the external space.
The principle of realizing the drip prevention of the drip prevention test box provided by the embodiment of the invention is as follows:
when the test box is used for a humidity condition test, a part of condensed water can be gathered on the inner wall of the box door 1. When the door 1 is opened, the condensed water drops down along the inner wall of the door 1 into the water chute 2 (as shown by the arrow L1 in fig. 2 and 3). At this time, the counterweight sealing block 3 provided in the water chute 2 seals the drain hole 201 at the bottom of the water chute 2 by gravity, and the condensed water is deposited in the water chute 2. When the box door 1 is closed, the counterweight sealing block 3 is supported by the water collecting tray 4 and lifted, the drain hole 201 is opened, and the condensed water stored in the water chute 2 flows into the water collecting tray 4 along with the drain hole 201 (as shown by an arrow L2 in fig. 3), finally reaches the device main drain port 401, and is finally discharged.
Therefore, the anti-dripping test box provided by the embodiment of the invention can prevent condensed water accumulated on the inner wall of the box door 1 from dripping on the ground when the box door 1 is opened, and the user experience is improved.
It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no precedence between the two is considered as indicating or implying relative importance.
The above description is only a few embodiments of the present invention, and those skilled in the art can make various changes or modifications to the embodiments of the present invention according to the disclosure of the application document without departing from the spirit and scope of the present invention.
