DETAILED DESCRIPTION

[0027] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0028] Example 1

[0029] refer to Figure 1-3 The present embodiment provides an oil cup device, which is applied to a range hood. The oil cup device includes a fixing box 1, an oil cup 2 and a switch assembly 3. The fixing box 1 has a mounting cavity 11 with a front opening, and an oil leakage hole 12 connected to the mounting cavity 11 is provided on the top of the fixing box 1. The oil cup 2 is detachably installed in the mounting cavity 11, and has a liquid storage cavity 21 opening upward, and the liquid storage cavity 21 is used to receive the fluid flowing down from the oil leakage hole 12. The fluid includes oil and of course, clean water. A grip portion 20 is provided on the front side wall of the oil cup 2, so that the user can push and pull the oil cup 2 through the grip portion 20.

[0030] The switch assembly 3 is an electric switch or a mechanized switch, which is movably disposed in the installation cavity 11, so as to hide the switch assembly 3 in the fixing box 1, and prevent the entire switch assembly 3 from being disturbed by oil smoke or oil. The switch assembly 3 is configured to open the oil leakage hole 12 when the oil cup 2 is pushed into the installation cavity 11, and to automatically close the oil leakage hole 12 when the oil cup 2 is pulled out of the installation cavity 11.

[0031] In this embodiment, the switch assembly 3 is a mechanized switch. When the oil cup 2 is pushed into the mounting cavity 11 of the fixing box 1, the switch assembly 3 can move backward under the push of the oil cup 2 and open the oil leakage hole 12. Figure 3-5 At this time, the fluid above the fixed box 1 can be discharged from the oil leakage hole 12 to the liquid storage cavity 21 of the oil cup 2 to collect the fluid; when the oil cup 2 is pulled out of the fixed box 1, the switch assembly 3 can automatically move forward and close the oil leakage hole 12, refer to Figure 2 , so that the oil droplets at the oil leakage hole 12 will not be discharged directly downward in the absence of the oil cup, thereby solving the problem that the oil droplets at the oil leakage hole 12 will directly drip into the fixing box 1 after the oil cup 2 is pulled out of the installation cavity.

[0032] refer to Figure 1-3, further, the switch assembly 3 includes an oil baffle plate 31 and an elastic member 32. The oil baffle plate 31 is movably arranged in the installation cavity 11 and is used to open or close the oil leakage hole 12. The elastic member 32 is preferably a reset spring, which is arranged below the rear end of the oil baffle plate 31. The front and rear ends of the elastic member 32 are respectively connected to the oil baffle plate 31 and the fixing box 1. In this embodiment, the preload force of the elastic member 32 always pushes the oil baffle plate 31 to move forward and always has a tendency to close the oil leakage hole 12, so that after the oil cup 2 is pulled out, the oil baffle plate 31 can move forward and close the oil leakage hole 12 under the push of the elastic member 32. When the oil cup 2 is pushed into the installation cavity 11, the thrust of the oil cup 2 is greater than the preload force of the elastic member 32, and the oil baffle plate 31 can move backward and open the oil leakage hole 12 under the push of the oil cup 2.

[0033] Furthermore, in order to facilitate the oil cup 2 to push the oil baffle plate 31 backward until the oil leakage hole 12 is opened, a pushing portion 22 arranged corresponding to the oil baffle plate 31 is provided on the front wall of the liquid storage chamber 21. The front end of the oil baffle plate 31 is configured to pass through or cross the rear side wall of the oil cup 2 and abut against the pushing portion 22, and the oil baffle plate 31 can move backward and open the oil leakage hole 12 under the push of the pushing portion 22. Therefore, when the oil cup 2 is pushed into the installation chamber 11, the front end of the oil baffle plate 31 passes through or crosses the rear side wall of the oil cup 2 and extends into the liquid storage chamber 21 until it abuts against the pushing portion 22 of the oil cup 2. As the oil cup 2 continues to be pushed into the fixing box 1, the pushing portion 22 moves backward with the oil cup 2, and simultaneously pushes the oil baffle plate 31 to move backward and open the oil leakage hole 12, so that the oil leakage hole 12 is connected with the liquid storage chamber 21 of the oil cup 2, so that the oil cup 2 can receive the fluid flowing down from the oil leakage hole 12.

[0034] In this embodiment, in order to facilitate the front end of the oil baffle plate 31 to pass through the rear side wall of the oil cup 2, a notch 23 is provided at the upper end of the rear side wall of the oil cup 2 for the oil baffle plate 31 to movably pass through. In other embodiments, the notch 23 may be omitted, and in this case, the rear side wall of the oil cup 2 is designed to be lower than the oil baffle plate 31, so that the front end of the oil baffle plate 31 can movably pass over the rear side wall of the oil cup 2.

[0035] In this embodiment, a reinforcing rib extending inwardly and arranged corresponding to the oil baffle plate 31 is integrally formed on the front wall of the liquid storage chamber 21, and the lower end of the reinforcing rib is integrally formed with the bottom surface of the liquid storage chamber 21 to separate the liquid storage chamber 21 into two connected left and right parts. The pushing portion 22 is composed of the reinforcing rib. In this way, the overall strength of the oil cup 2 is strengthened and the liquid storage chamber 21 is divided into two parts through the setting of the reinforcing rib, and the reinforcing rib is ensured to reliably push the oil baffle plate 31 backward and open the oil leakage hole 12 when the oil cup 2 is pushed into the fixing box 1. In other embodiments, the lower end of the reinforcing rib can be separated from the bottom surface of the liquid storage chamber 21, and of course, the reinforcing rib can also be omitted. When the reinforcing rib is omitted, the pushing portion 22 is instead composed of a partial front wall of the liquid storage chamber 21, that is, the pushing portion 22 is composed of the portion of the front wall of the liquid storage chamber 21 corresponding to the gripping portion 20.

[0036] In order to further increase the contact area between the push portion 22 and the oil baffle plate 31, and to facilitate the oil baffle plate 31 to connect to the front end of the elastic member 32, the front end of the oil baffle plate 31 is integrally formed and bent downward to form a convex edge 311, so that the oil baffle plate 31 is in an inverted "L" shape, and the convex edge 311 is closer to the push portion 22 of the oil cup 2. Of course, the convex edge 311 can also be integrally formed and set in the middle of the bottom surface of the oil baffle plate 31, so that the oil baffle plate 31 is in a "T" shape, so that the overall length of the elastic member 32 can be shortened. In this embodiment, the convex edge 311 is connected to the front end of the elastic member 32, and the convex edge 311 is configured to abut against the push portion 22. When the oil cup 2 is pushed into the fixed box, the convex edge 311 can move backward under the push of the pushing part 22, so that the oil baffle plate 31 opens the oil leakage hole; conversely, when the oil cup 2 is pulled out of the fixed box, the convex edge 311 can move forward under the push of the pre-tightening force of the elastic member 32, so that the oil baffle plate 31 closes the oil leakage hole.

[0037] Furthermore, in order to fix the rear end of the elastic member 32 in the fixing box 1, a positioning portion 13 extending toward the inside of the installation cavity 11 is integrally formed on the top cavity wall of the installation cavity 11. Of course, the positioning portion 31 can also be changed to be integrated on the rear cavity wall of the installation cavity 11, and the positioning portion 13 is connected to the rear end of the elastic member 32. Therefore, through the cooperation of the positioning portion 13 and the flange 311, the elastic member 32 is reliably fixed and installed at the bottom of the oil baffle plate 3 and behind the flange 311. In addition, in order to avoid interference with the rearward movement of the oil baffle plate 31 due to the setting of the positioning portion 13, and thus avoid affecting the opening of the oil leakage hole of the oil baffle plate 31, an air avoidance hole 312 is provided at the rear end of the oil baffle plate 31 at the position corresponding to the positioning portion 13, refer to Figure 1 The air avoidance hole 312 is configured to accommodate the upper end of the positioning portion 13 so that when the oil baffle plate 31 opens the oil leakage hole, the upper end of the positioning portion 13 can be inserted into the air avoidance hole 312 .

[0038] refer to Figure 1 Furthermore, the oil cup device also includes two guide rails 4. Two guide rails 4 are provided in the installation cavity 11 and are located on the left and right outer sides of the oil baffle plate 31. The two guide rails 4 are slidably connected to the left and right ends of the oil baffle plate 31 respectively. In this way, the guide rails 4 can not only guide the forward and backward movement of the oil baffle plate 31, but also reliably support the oil baffle plate 31 to prevent the oil baffle plate 31 from shifting left and right during movement.

[0039] In this embodiment, the two guide rails 4 are both arranged behind the convex edge 311 of the oil baffle plate 31, so that the two guide rails 4 can limit the rearward movement of the convex edge 311 and the oil cup 2. Each guide rail 4 includes a horizontal section and a vertical section fixedly connected to form an "L" or inverted "T" shape. The vertical section is arranged on the left or right outer side of the oil baffle plate 31, and its upper and lower ends are respectively integrally formed with the top of the fixed box 1 and the horizontal section. The horizontal section is arranged below the rear end of the oil baffle plate 31 and is located behind the convex edge 311. A slide groove opening toward the oil baffle plate 31 is formed between the horizontal section and the vertical section, and the left and right ends of the oil baffle plate 31 can be inserted into the slide grooves of the two guide rails 4 so as to move forward and backward.

[0040] Furthermore, a locking assembly (not shown in the figure) is included, and the oil cup 2 and the fixed box 1 are locked or unlocked by at least one locking assembly. Thus, the oil cup 2 is locked in the fixed box 1 by the locking assembly to prevent the oil cup 2 from being pushed out of the fixed box 1 by the pre-tightening force of the switch assembly 3, so that the oil cup 2 is firmly and reliably detachably installed in the fixed box 1, and the switch assembly 3 is maintained in a state where the oil leakage hole 12 is opened.

A hook 14 is formed at the bottom of the installation cavity 11 at a position corresponding to the slot 241. The outer edge of the hook 14 is cut and separated from the bottom of the installation cavity 11 so that the hook 14 has a certain elastic deformation ability. The hook 14 is used to hook with the rear groove wall of the slot 241. When the oil cup 2 is pushed into the fixed box 1, the pushing part 22 pushes the oil baffle 31 backward, and the elastic member 32 is compressed until the slot 241 of the oil cup 2 is hooked by the hook 14 of the fixed box 1, so that the oil cup 2 is locked in the fixed box 1. Of course, the slot 241 can also be set on the rear side wall of the oil cup 2 and open toward the rear. It is formed by punching a part of the rear side wall of the oil cup 2 toward the front. Correspondingly, the hook 14 is integrated on the rear wall of the installation cavity 11.

[0043] The second one, reference Figure 5 The hook assembly includes a locking hole 242 and a hook 14. The locking holes 242 are respectively opened on the left and right sides of the upper end of the rear side wall of the oil cup 2. The hook 14 is formed at the position of the rear cavity wall of the installation cavity 11 corresponding to the locking hole 242. The hook 14 is used to hook with the edge of the locking hole 242.
