Description

Technical Field

[0001] The invention relates to the technical field of pet appliances, and in particular to a cat litter box. Background Art

[0002] The cat litter in the cat litter box is mainly used to wrap the excrement of pet cats. Usually, after the pet cats have finished using it, the breeder will clean out the clumped excrement in the cat litter to keep the cat litter clean. However, the manual operation of separating the excrement from the cat litter is cumbersome, and the breeder cannot always pay attention to the condition of the cat litter box. Based on this, cat litter boxes with automatic cleaning devices are gradually appearing on the market, which can automatically clean the cat litter to clean out the excrement after the pet cats have excreted, keep the cat litter box clean, and relieve the breeder.

[0003] However, the existing automatic cleaning devices mostly use a cat litter screen that is arranged to move horizontally along the bottom of the cat litter containing chamber to screen out the waste along the movable stroke of the cat litter screen and clean out the cat litter containing chamber. This arrangement of the cat litter screen's movable stroke covers the entire cat litter containing chamber, which can ensure that the waste is completely screened out. However, when the cat litter screen moves horizontally to push the waste out of the cat litter containing chamber, there is a situation where the waste is attached to the cat litter screen and cannot be cleared out, and is mixed back into the cat litter containing chamber as the cat litter screen retreats, affecting the cleaning effect. Summary of the invention

[0057] The cat litter in the cat litter box is mainly used to wrap the excrement of pet cats. Usually, after the pet cats have finished using it, the breeder will clean out the clumped excrement in the cat litter to keep the cat litter clean. However, the manual operation of separating the excrement from the cat litter is cumbersome, and the breeder cannot always pay attention to the condition of the cat litter box. Based on this, cat litter boxes with automatic cleaning devices are gradually appearing on the market, which can automatically clean the cat litter to clean out the excrement after the pet cats have excreted, keep the cat litter box clean, and relieve the breeder.

[0058] However, the existing automatic cleaning devices mostly use a cat litter screen that is arranged to move horizontally along the bottom of the cat litter containing chamber to screen out the waste along the movable stroke of the cat litter screen and clean out the cat litter containing chamber. This arrangement of the cat litter screen's movable stroke covers the entire cat litter containing chamber, which can ensure that the waste is completely screened out. However, when the cat litter screen moves horizontally to push the waste out of the cat litter containing chamber, there is a situation where the waste is attached to the cat litter screen and cannot be cleared out, and is mixed back into the cat litter containing chamber as the cat litter screen retreats, affecting the cleaning effect.

[0059] In view of this, the present invention provides a cat litter box. Figures 1 to 9 An embodiment of a cat litter box provided by the present invention will be described below in conjunction with specific drawings.

[0060] See also Figures 1 to 9The cat litter box 100 includes a main body 1, a cleaning mechanism 2, a driving mechanism 3 and an adjusting structure, wherein a receiving groove 11 is provided on the upper side of the main body 1, and a cleaning port 12 is provided at one side end of the receiving groove 11 in the horizontal direction, and the receiving groove 11 is used to carry cat litter; the cleaning mechanism 2 includes a sand shovel 21 arranged in the receiving groove 11, and the sand shovel 21 moves along the inner wall of the receiving groove 11 distributed in the horizontal direction; the driving mechanism 3 is arranged on the main body 1 and is driven and connected with the sand shovel 21, and the connection between the driving mechanism 3 and the sand shovel 21 can be rotatably arranged to drive the sand shovel 21 to move; the adjusting structure is used to adjust the sand shovel 21 during the movement of the sand shovel 21, so that the sand shovel 21 rotates relative to the driving mechanism 3 when it is close to the cleaning port 12, so that the sand shovel 21 at least has a top end thereof rotating toward the cleaning port 12 to dump the sewage into the cleaning port 12.

[0061] In the technical solution of the present invention, a sand shovel 21 is arranged in the receiving groove 11, and the sand shovel 21 is connected to the driving mechanism 3. The driving mechanism 3 drives the sand shovel 21 to move between the two inner walls of the receiving groove 11 in the horizontal direction, so as to screen out the waste in the cat litter and drive it to the cleaning port 12 for discharge, thereby realizing automatic cleaning of the waste. In addition, when the sand shovel 21 is driven by the driving mechanism 3 to move, the adjustment structure is used to adjust the sand shovel 21 so that it rotates relative to the driving mechanism 3, thereby realizing that when the sand shovel 21 is close to the cleaning port 12, the sand shovel 21 is driven to rotate to the dumping state. During the rotation process, the waste attached to the sand shovel 21 can roll down along the surface of the sand shovel 21 due to its own gravity, thereby realizing the cleaning of the waste and preventing the waste attached to the sand shovel 21 from returning to the receiving groove 11 with the sand shovel 21, thereby improving the stability of the cat litter box 100 in automatically cleaning the waste.

[0062] Specifically, the side of the main body 1 in the longitudinal direction is the installation side 13, and at least one of the installation sides 13 is provided with a first track 131, and the first track 131 extends in the transverse direction; the driving mechanism 3 includes a driving slider 31 sliding on the first track 131, and the driving slider 31 is rotatably connected to the sand shovel 21 through a connecting member 22, and the adjusting structure adjusts the connecting member 22 to drive the sand shovel 21 to rotate. The driving mechanism 3 is arranged on the side of the main body 1 in the longitudinal direction to prevent the driving mechanism 3 from being arranged in the receiving groove 11. On the one hand, it prevents cat litter and other debris from entering the driving mechanism 3 and thus affecting the activity of the driving mechanism 3 or even causing different degrees of damage. On the other hand, it prevents the driving power device on the driving mechanism 3 from being exposed in the receiving groove 11, thereby preventing it from causing possible harm to the pet cat. In this embodiment, the first rail 131 is provided on the installation side 13, and the driving slider 31 is provided on the first rail 131. The driving slider 31 can move along a fixed track to drive the sand shovel 21 to move along a fixed route through the connecting member 22, thereby ensuring the stability of the sand shovel 21 in multiple cleanings of the containing groove 11.

[0063] It should be noted that the rotation connection point between the connecting member 22 and the driving slider 31 corresponds to the lower part of the sand shovel 21, so that the force application point of the driving slider 31 is located at the lower part of the sand shovel 21, and its height is close to the center of gravity height of the cat litter in the receiving tank 11, so that it can provide greater driving power, facilitate driving the sand shovel 21 to move, and make the sand shovel 21 less likely to be blocked and stagnant. In addition, the connection point between the connecting member 22 and the driving slider 31 is fixed, so that when the driving slider 31 drives the sand shovel 21 to move to screen out the waste in the cat litter, the power output height of the driving slider 31 and the center of gravity height of the cat litter in the receiving tank 11 remain constant, thereby improving the stability of the operation of the sand shovel 21.

[0064] Furthermore, the connecting member 22 has an upper section and a lower section located at the upper and lower sides of the rotational connection between the connecting member 22 and the driving slider 31; the adjusting structure includes a first stop portion 134, which is longitudinally protruded from the mounting side 13 and is arranged close to the cleaning port 12, so as to abut against the lower section of the connecting member 22; wherein, in the stroke in which the driving slider 31 drives the connecting member 22 to move toward the cleaning port 12, the sand shovel 21 has a cleaning state in which it extends into the accommodating groove 11 and moves toward the cleaning port 12; the lower section of the connecting member 22 abuts against the first stop portion 134, so that the connecting member 22 rotates around the first stop portion 134, so that the sand shovel 21 has the tilting state in which its top end rotates toward the cleaning port 12. The adjustment structure drives the connection member 22 to rotate and then drives the sand shovel 21 to rotate by setting an additional driving member at the connection between the driving slider 31 and the connection member 22 to drive the connection member 22, or by using the driving slider 31 itself to drive the connection member 22 to move the active stroke, and by setting a certain stop structure to limit the movement of part of the connection member 22 to produce a rotation effect. In this embodiment, the adjustment structure is set as a stop structure to use the driving slider 31 to drive the connection member 22 to rotate. The design is ingenious, the control process is simple and the cost is low. Specifically, the connecting member 22 moves toward the cleaning port 12 to perform the cleaning operation until the lower section of the connecting member 22 abuts against the first stop portion 134, at which time the lower section of the connecting member 22 is restricted in movement by the first stop portion 134, and the driving slider 31 drives the upper section of the connecting member 22 to continue to move, causing the top end of the connecting member 22 to lift up and rotate toward the cleaning port 12, thereby driving the top end of the sand shovel 21 connected thereto to rotate toward the cleaning port 12 and enter the dumping state, thereby increasing the inclination of the sand shovel 21, facilitating the sliding of waste, preventing waste from adhering to the sand shovel 21, and thereby preventing waste from performing subsequent activities with the sand shovel 21 and causing secondary pollution to the cat litter.

[0065] In addition, the adjustment structure also includes a second stop portion 135, which protrudes longitudinally from the installation side 13 and is located at the end of the first rail 131 away from the cleaning port 12, and is used to abut against the lower section of the connecting member 22; during the stroke in which the driving slider 31 drives the connecting member 22 to move away from the cleaning port 12, the lower section of the connecting member 22 abuts against the second stop portion 135, so that the connecting member 22 rotates around the second stop portion 135, so that the sand shovel 21 has a storage state in which its top end is rotated and attached to the groove wall of the accommodating groove 11. In order to facilitate the sand shovel 21 to retreat to the groove wall attached to the receiving groove 11, the adjustment structure is also provided with a second stop portion 135. Specifically, when the driving slider 31 enters the retraction stroke, it drives the connecting member 22 to retreat. Based on the fact that the connection point between the connecting member 22 and the driving slider 31 corresponds to the lower part of the sand shovel 21, the driving slider 31 drives the lower section of the connecting member 22 to rotate from the state of extending forward toward the cleaning port 12 to extending forward in the direction away from the cleaning port 12 to form a sand shoveling shape. The cat litter can be screened again during the retraction process, further improving the cleanliness of the cat litter in the middle position of the receiving groove 11. Until the driving slider 31 drives the lower section of the connecting member 22 to abut against the second stop portion 135, the driving slider 31 continues to move to drive the upper section of the connecting member 22 to rotate away from the cleaning port 12, until the connecting member 22 drives the sand shovel 21 to rotate to adhere to the groove wall of the receiving groove 11 and enter the storage state, thereby reducing the space occupied by the sand shovel 21 in the receiving groove 11.

[0066] Specifically, the first stopper 134 and / or the second stopper 135 include a stopper protrusion protruding from the mounting side 13. The first stopper 134 and the second stopper 135 can be arranged in various forms, including a structure that can be detachably mounted on the mounting side 13, etc., as long as the connecting member 22 can be stopped to prevent it from crossing over, and no limitation is made here. In this embodiment, the first stopper 134 and the second stopper 135 are directly arranged as stopper protrusions protruding from the mounting side 13, which have a simple structure, low cost, and are reliable.

[0067] In addition, the adjustment structure also includes a third stop portion 133, which is longitudinally protruded from the installation side 13 and is arranged close to the cleaning port 12. The first stop portion 134 is arranged closer to the cleaning port 12 than the third stop portion 133. The third stop portion 133 can be longitudinally elastically extended and retracted to abut against the upper section of the connecting member 22; the upper section of the connecting member 22 abuts against the third stop portion 133, so that the connecting member 22 rotates around the third stop portion 133, so that the sand shovel 21 has a lifting state with its bottom end lifted up, so as to drive the waste out of the cat litter; the connecting member 22 rotates until its lower section abuts against the first stop portion 134, and the connecting member 22 rotates around the first stop portion 134 to press against and pass over the third stop portion 133. Specifically, because the first stop portion 134 is arranged closer to the cleaning port 12 than the third stop portion 133, when the connecting member 22 moves toward the cleaning port 12 for cleaning operation, the connecting member 22 preferentially moves to abut against the third stop portion 133, that is, the upper section of the connecting member 22 abuts against the third stop portion 133 and is restricted from movement by the third stop portion 133, and the driving slider 31 drives the lower section of the connecting member 22 to continue to move, causing the bottom end of the connecting member 22 to rotate and lift up, thereby driving the bottom end of the sand shovel 21 connected thereto to lift upward and enter the lifting state, so that the sand shovel 21 can be removed from the cat litter, thereby achieving the effect of separating the cat litter and reducing waste. The driving slider 31 continues to move until the lower section of the connecting member 22 abuts against the first stop portion 134, and the connecting member 22 is restricted and cannot move. At this time, because the third stop portion 133 is longitudinally elastic, the driving force of the driving slider 31 is applied to the connecting member 22 to push the third stop portion 133 to contract, so that the connecting member 22 passes over the third stop portion 133. At this time, the driving slider 31 can continue to drive the upper section of the connecting member 22 to move, so that the sand shovel enters the above-mentioned dumping state. After the waste is dumped, the driving slider 31 drives the connecting member 22 to move away from the cleaning port 12. The upper section of the connecting member 22 preferably abuts against the third stop portion 133, so that the connecting member 22 rotates around the third stop portion 133, so that the sand shovel 21 has an adjustment state in which its bottom end rotates away from the cleaning port 12, until the connecting member 22 presses against and passes over the third stop portion 133, so that the sand shovel 21 has a retreat state moving away from the cleaning port 12.

[0068] In summary, the cleaning process of the sand shovel 21 includes the cleaning state, the lifting state and the dumping state during the movement toward the cleaning port 12, and the adjustment state, the retreat state and the storage state during the movement away from the cleaning port.

[0069] In addition, the third stopper 133 includes a protrusion 133a and an elastic member, one end of the protrusion 133a is rotatably mounted on the mounting side 13; the elastic member connects the mounting side 13 and the other end of the protrusion 133a. In order to prevent the protrusion 133a from falling off, the protrusion 133a is set to be rotatably mounted on the mounting side 13 at one end, so that its movement is more stable. At the same time, in order to prevent the protrusion 133a from rotating arbitrarily and affecting the movement of the connecting member 22 in a free state, the other end of the protrusion 133a is connected to the mounting side 13 using the elastic member, so as to prevent the protrusion 133a from moving arbitrarily while realizing its elastic movement function. In addition, the two sides of the protrusion 133a abutting against the connecting member 22 are set as slopes, so that the connecting member 22 can press the protrusion 133a and pass over the protrusion 133a.

[0070] Furthermore, the end of the protrusion 133a that is close to the cleaning port 12 in the horizontal direction is provided with a first slope surface, and the end that is away from the cleaning port 12 is provided with a second slope surface, and the first slope surface and the second slope surface are used to stop the connecting member 22 and allow the connecting member 22 to press against and pass over the protrusion 133a; wherein the slope of the first slope surface is greater than the slope of the second slope surface. In the two strokes of the connecting member 22 approaching or away from the cleaning port 12, the rotation strokes of the connecting member 22 that press against the protrusion 133a for rotation are different, so it is necessary to set the slopes of the first slope surface and the second slope surface to be different to provide different sizes of resistance, so as to ensure that the connecting member 22 passes over the protrusion 133a after completing the rotation stroke and avoid excessive resistance affecting the normal movement of the connecting member 22. Specifically, the rotation stroke of the connecting member 22 is relatively large when it retreats, so the slope of the first slope surface is set to be relatively large, so that the slope surface is relatively steep and the resistance is large, so as to meet the relatively large rotation stroke of the connecting member 22 and prevent it from crossing the protrusion 133a in advance. On the contrary, during the active stroke of the connecting member 22 close to the cleaning port 12, its rotation stroke is relatively small, so the slope of the first slope surface is set to be relatively small to avoid causing a large obstruction to the connecting member 22.

[0071] Specifically, the accommodating groove 11 includes a bottom wall 111, and a first side wall 112 and a second side wall 113 located in the horizontal direction of the bottom wall 111, and the second side wall 113 is arranged close to the cleaning port 12; the first track 131 includes a first track segment 131b and a second track segment 131c, and the first track segment 131b extends in the horizontal direction; the second track segment 131c corresponds to the second side wall 113 and extends in the up and down directions, and the lower end of the second track segment 131c is connected to one end of the first track segment 131b. The first track 131 is set to correspond to the shape of the receiving groove 11, specifically, the receiving groove 11 is set to be a groove clamped by the first side wall 112 and the second side wall 113, and the first track 131 is correspondingly set to an arc shape, so that the first track segment 131b corresponds to the bottom wall 111, and the second track segment 131c corresponds to the second side wall 113. Such a setting ensures that when the driving slider 31 moves along the first track 131, it can drive the sand shovel 21 to move in accordance with the shape of the receiving groove 11, so as to ensure that the cat litter in the receiving groove 11 is cleaned without dead angles, thereby improving the cleaning effect.

[0072] It should be noted that when the driving slider 31 moves from bottom to top along the first track segment 131b, the connection point between the connecting piece 22 and the driving slider 31 is located at the lower part of the sand shovel 21, and the sand shovel 21 extends into the cat litter. The cat litter on the sand shovel 21 gives the sand shovel 21 a certain resistance, so that the driving slider 31 drives the lower end of the sand shovel 21 to move upward, and the sand shovel 21 as a whole is subjected to the resistance of the cat litter, so that the upper end of the sand shovel 21 is delayed in moving up or even does not move up compared with the lower end of the sand shovel 21, thereby causing the sand shovel 21 to rotate to achieve the above-mentioned lifting state; conversely, during the retreat of the sand shovel 21, the force application point of the driving slider 31 corresponds to the lower end of the sand shovel 21, so as to preferentially drive the lower end of the sand shovel 21 to move away from the cleaning port 12, thereby achieving the above-mentioned adjustment state. Therefore, in the present application, based on the setting of the first track segment 131b, whether the third stopper 133 is set or not does not affect the lifting state and the adjustment state during the movement of the sand shovel 21. Therefore, in the first embodiment of the present application, the third stopper 133 is set, and in the second embodiment of the present application, the setting of the third stopper 133 is cancelled. It can be understood that although the third stopper 133 does not affect the above two states of the sand shovel 21, the setting of the third stopper 133 obviously makes the implementation of the above two states more stable, and not setting the third stopper 133 reduces the manufacturing cost. Therefore, the above first embodiment and the second embodiment proposed in the present application have their own advantages and disadvantages, and either one can be adopted, and it is not limited here.

[0073] Furthermore, the first track 131 also includes a third track segment 131a, which corresponds to the first side wall 112 and extends in the up-down direction, and the lower end of the third track segment 131a is connected to the other end of the first track segment 131b. The third track segment 131a is arranged so that the driving slider 31 can drive the sand shovel 21 to move upward, so that the sand shovel 21 in the storage state is separated from the cat litter in the receiving groove 11, on the one hand, the sand shovel 21 is better attached to the inner wall of the receiving groove 11, and avoids the problem that when the receiving groove 11 is set in an arc shape, the sand shovel 21 simultaneously abuts the bottom and the inner wall, resulting in a certain angle between it and the inner wall, and cannot be completely attached and there is a gap; on the other hand, it is prevented that the sand shovel 21 is placed in the cat litter for a long time, reduces the pollution of the sand shovel 21, and prevents the cat litter from adhering to the sand shovel 21, which is conducive to keeping the sand shovel 21 clean.

[0074] In addition, the mounting side 13 is further provided with a second track 132 above the first track 131, the second track 132 includes a fourth track segment 132a, a fifth track segment 132b and a sixth track segment 132c, the fourth track segment 132a extends up and down and corresponds to the third track segment 131a; the fifth track segment 132b extends laterally and corresponds to the first track segment 131b, the fifth track segment 132b is connected to the lower end of the third track; the sixth track segment 132c extends up and down and corresponds to the second track segment 131c, the sixth track segment 132c is connected to the other end of the fifth track segment 132b; the connecting member 22 is provided with a sliding portion 221 adapted to the second track 132. The second track 132 is provided on the installation side 13, and the sliding part 221 is provided on the connecting member 22, so that the connecting member 22 has two supporting points, namely the driving slider 31 connected to the connecting member 22 and the second track 132 supporting the sliding part 221, so that when the driving slider 31 drives the connecting member 22 to move, the sliding part 221 moves along the second track 132, so that the inclination angle of the sand shovel 21 can maintain the set value to keep stable, and ensure the stability of the cat litter cleaning process. The inclination angle of the sand shovel 21 can be adjusted by the distance between the first track 131 and the second track 132. The closer the distance, the smaller the angle between the sand shovel 21 and the slot wall of the accommodating slot 11, and vice versa. The angle is set according to actual needs and is not limited here.

[0075] It can be understood that, in combination with the structural arrangement of the first track 131 and the second track 132, the specific process of the driving slider 31 driving the connecting member 22 to move is that when the driving slider 31 moves downward from the third track segment 131a, the sand shovel 21 extends downward into the receiving groove 11 to extend into the cat litter, and then the driving slider 31 translates along the first track segment 131b, driving the sliding part 221 to slide along the fifth track segment 132b. At this time, the driving slider 31 located below the sliding part 221 acts as a power source to pull the connecting member 22, so that the lower end of the connecting member 22 extends forward along the moving direction, so as to drive the lower end of the sand shovel 21 to extend forward to form a sand shoveling shape, and translate close to the bottom wall 111 of the receiving groove 11 to shovel out the waste. When the sand shovel 21 enters the lifting state, the connecting member 22 drives the sand shovel 21 to rotate, and its rotation center is located above the driving slider 31. At this time, the driving slider 31 moves upward along the second track section 131c to drive the bottom of the sand shovel 21 to lift, so that the sand shovel 21 drives the waste to escape from the cat litter. Until the connecting member 22 rotates until it is stopped by the first stopper 134, the driving slider 31 continues to move so that the sand shovel 21 switches to the dumping state. The driving slider 31 drives the connecting member 22 to rotate around the first stopper 134, so that the top of the sand shovel 21 rotates toward the cleaning port 12, so as to tilt the sand shovel 21 to dump the waste into the cleaning port 12, and complete the cleaning operation of the cat litter.

[0076] Further, in combination with the structural arrangement of the first track 131 and the second track 132, during the reverse recovery process of the sand shovel 21, the driving slider 31 moves downward along the second track segment 131c, at which time the connecting member 22 and the first stopper 134 are separated from the abutting state, and then the driving slider 31 drives the sand shovel 21 to enter the adjustment state, that is, the driving slider 31 drives the connecting member 22 to rotate, so as to drive the bottom end of the sand shovel 21 to rotate to extend forward in the direction of its movement to form a sand shovel shape, until Until the sand shovel 21 stops rotating and maintains the tilted angle and cleans in the reverse direction along the receiving groove 11, the lower section of the connecting member 22 abuts against the second stop portion 135, and the driving slider 31 pushes the connecting member 22 to rotate, so that the upper end of the sand shovel 21 rotates toward the first side wall 112 until it is attached to the first side wall 112. At this time, the driving slider 31 moves upward along the third track section 131a to drive the sand shovel 21 to move upward, so that the sand shovel 21 escapes from the cat litter in the receiving groove 11.

[0077] In addition, a rack is provided in the first track 131, and a driving gear is provided on the driving slider 31. The driving gear cooperates with the rack so that the driving slider 31 moves in the first track 131. The driving slider 31 can move in other ways such as a roller contacting the first track 131, as long as it can ensure that the driving slider 31 moves stably on the first track 131, which is not limited here. In this embodiment, the gear rack cooperation mode is adopted, that is, the driving gear moves on the rack, and it will not slip, etc., and the movement is more stable.

[0078] In addition, the cat litter box 100 also includes a sewage discharge device 4, which is arranged at the cleaning port 12 and is used to discharge the sewage dumped by the sand shovel 21 out of the cat litter box 100; the sewage discharge device 4 includes a movable cover plate 41 rotatably installed at the cleaning port 12, so that in the rotation stroke of the movable cover plate 41, there is a covering state in which the movable cover plate 41 covers the cleaning port 12 and an open state in which the cleaning port 12 is opened; a pushing member is provided on at least one side between the movable cover plate 41 and the driving slider 31, so that when the driving slider 31 moves along the first track to approach the cleaning port 12, the driving slider 31 pushes and drives the movable cover plate 41 to switch from the covering state to the open state. The sewage discharge device 4 can be a sewage discharge channel arranged at the cleaning port 12 to guide the sewage out of the cat litter box 100. Such an arrangement has restrictions on the placement of the cat litter box 100, which must be close to the external garbage cleaning device, which is not convenient for the free use of the cat litter box 100. Therefore, in this embodiment, the sewage discharge device 4 is set as a concentrator 42 and a collection device 43 to collect and collect the sewage falling from the cleaning port 12 to the collection device 43, which is convenient for unified dumping, and removes the installation position restriction of the cat litter box 100, which is more convenient for use. Furthermore, the movable cover plate 41 is provided at the cleaning port 12 to cover the sewage discharge device 4 to prevent the pet cat from mistakenly entering the collection device 43 and affecting the collection effect. As for the driving method of the movable cover plate 41, an independent driving member may be provided for driving. However, such a setting obviously requires certain program design costs and structural design costs to ensure synchronization with the movement of the sand shovel 21, which is not convenient for daily use. Therefore, in the present embodiment, the movable cover plate 41 is lifted up by the movement of the driving slider 31, which has a clever design, a high synchronization rate and a lower cost.

[0079] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
