[0005] In order to adjust the diffusion speed of the fragrance on the scent sheet, thereby adjusting the fragrance concentration in the car and reducing waste, the utility model provides a hard and non-deformable fragrance paper sheet.

[0006] The utility model provides a hard and non-deformable scented paper sheet, a hard and non-deformable scented paper sheet comprising a box body, a hole-shielding component, a connecting component and a clamping component, a scented paper body is arranged inside the box body, a discharge port is arranged on one side of the box body, a flip cover is hinged on the box body, the flip cover is clamped on the box body through the clamping component, a plurality of first air holes are provided on the side walls on both sides of the box body, a accommodating cavity is provided on the box body, the hole-shielding component comprises a first baffle and a second baffle, the first baffle and the second baffle are arranged in the accommodating cavity, and slide in contact with the side walls on both sides of the accommodating cavity, a plurality of second air holes are arranged on the first baffle and the second baffle, a control structure for controlling the sliding position of the first baffle and the second baffle is arranged on the box body, and the fragrance passes through the first air hole and the second air hole and is emitted to the outside of the box body.

[0007] By adopting the above technical solution, after the scent piece is placed in the box body, the fragrance emitted from the scent piece passes through the first air hole and the second air hole and is emitted to the outside of the box body. When the fragrance in the car is too strong, the control structure is used to adjust the sliding position of the first baffle plate and the second baffle plate to reduce the size of the overlapping surface of the first air hole and the second air hole, thereby achieving the effect of reducing the fragrance emission speed, thereby achieving the effect of reducing the fragrance concentration in the car; if it is no longer necessary to emit fragrance, the control structure can be used to adjust the sliding position of the first baffle plate and the second baffle plate to eliminate the overlapping surface between the first air hole and the second air hole, so that the fragrance is sealed in the box body and is difficult to be emitted to the outside of the box body, so that the fragrance is no longer emitted. When the fragrance in the car is too weak, the control structure is used to adjust the sliding position of the first baffle and the second baffle, so that the size of the overlapping surface of the first air hole and the second air hole is increased, so as to increase the fragrance dissipation speed, thereby achieving the effect of increasing the fragrance concentration in the car; therefore, the first baffle, the second baffle and the control structure are arranged, and since the fragrance dissipation speed is proportional to the size of the overlapping surface, the user can control the sliding position of the first baffle and the second baffle through the control structure, thereby controlling the size of the overlapping surface between the first air hole and the second air hole, and achieving the effect of controlling the fragrance dissipation speed on the scented sheet body, thereby being able to adjust the fragrance concentration in the car and reduce waste.

Therefore, the setting of the partition makes it difficult for the scented sheet body to contact the first baffle or the second baffle. When the user moves the first baffle or the second baffle, it is difficult for the first baffle or the second baffle to have relative friction with the scented sheet body, thereby reducing the wear of the first baffle or the second baffle on the scented sheet body during movement; and multiple partitions are in contact with the side walls of the first baffle or the second baffle, which is used to reduce the frequency of shaking of the first baffle or the second baffle during movement.

[0010] Optionally, the control structure includes a screw and a threaded sleeve, the screw is rotatably connected to the box body, the box body is slidably connected to the threaded sleeve by providing a sliding groove, and the first baffle and the second baffle are both fixedly connected to the threaded sleeve.

[0011] By adopting the above technical scheme, after the scented sheet body is placed in the box body, when it is necessary to adjust the speed of the fragrance emission from the scented sheet body, the screw is rotated, the threaded sleeve moves along the length direction of the screw, the first baffle and the second baffle move, their sliding positions change, the size of the overlapping surface between the first air hole and the second air hole changes, and the speed of the fragrance emission from the scented sheet body is controlled to change, thereby achieving the effect of controlling the speed of the fragrance emission from the scented sheet body. Therefore, with the setting of the screw and the threaded sleeve, the user can control the sliding position of the first baffle and the second baffle by rotating the screw, and the operation is simple and convenient.

[0012] Optionally, one end of the screw is rotatably mounted on the box body, and the other end is extended outside the box body and fixedly connected with a knob.

[0013] By adopting the above technical solution, when it is necessary to control the rotation of the screw, the rotation direction of the screw can be controlled by turning the knob, and the sliding position of the first baffle and the second baffle can be controlled by the threaded sleeve. Therefore, the setting of the knob facilitates the user to control the sliding position of the first baffle and the second baffle through the screw and the threaded sleeve, thereby adjusting the size of the overlapping surface between the first air hole and the second air hole, and achieving the effect of controlling the fragrance release speed on the fragrance sheet body.

[0014] Optionally, the connecting assembly includes a connecting plate, a first clamping plate and a second clamping plate, the connecting plate is arranged on the box body, the first clamping plate and the second clamping plate are symmetrically and obliquely arranged on the connecting plate, and a clamping cavity is formed between the first clamping plate, the second clamping plate and the connecting plate.

[0015] By adopting the above technical scheme, when the scented sheet is installed on the air plate of the vehicle air conditioner, the first clamping plate and the second clamping plate are made to contact with the air plate of the vehicle air conditioner, and then the box body is pressed toward the air plate, so that the side edges of the two connecting clamping plates are respectively located on both sides of the air plate, and as the box body approaches the air plate, the air plate enters the clamping cavity, and the clamping surfaces of the first clamping plate and the second clamping plate are abutted against the side walls of the air plate, and move in directions away from each other, and the first clamping plate and the second clamping plate clamp the air plate under the elastic action of themselves, so that the box body is fixedly clamped on the air plate; therefore, the setting of the connecting plate, the first clamping plate and the second clamping plate makes it convenient for the user to clamp the scented sheet on the air plate of the vehicle air conditioner, and it is difficult to shake during use, it is difficult to disturb the driver's driving, and it is not easy to have driving safety hazards.

[0016] Optionally, a first guide surface is formed between an end surface of the first clamping plate away from the connecting plate and an end surface close to the second clamping plate, and a second guide surface is formed between an end surface of the second clamping plate away from the connecting plate and an end surface close to the first clamping plate.

[0017] By adopting the above-mentioned technical scheme, when installing the scented sheet on the air plate of the vehicle air conditioner, the first guide surface and the second guide surface are aligned with the air plate, and the box body is lightly pressed so that the air plate abuts against the first guide surface and the second guide surface, and the first clamping plate and the second clamping plate are forced to move in the direction away from each other at one end away from the connecting plate until the air plate is inserted into the clamping cavity. The first clamping plate and the second clamping plate clamp the box body on the air plate under the action of elastic force; therefore, the setting of the first guide surface and the second guide surface further facilitates the user to place the air plate into the clamping cavity, so that the box body can be more conveniently clamped and installed on the air plate.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. Since the speed of fragrance emission is proportional to the size of the overlapped surface, the user can control the sliding position of the first baffle and the second baffle through the screw and the threaded sleeve, thereby controlling the size of the overlapped surface between the first air hole and the second air hole, and achieving the effect of controlling the speed of fragrance emission on the scent sheet body, thereby adjusting the fragrance concentration in the car and reducing waste.

[0029] The following combination Figure 1-Figure 5 The utility model is described in further detail.

[0030] This embodiment discloses a hard and non-deformable scent paper: Figure 1-Figure 5 A hard and non-deformable scented paper sheet comprises a box body 10, a hole-shielding component 20, a connecting component 40 and a clamping component 50. A scented paper sheet body 11 is arranged on the inner side of the box body 10, a discharge port 12 is arranged on one side of the box body 10, a flip cover 13 is hinged on the box body 10, and the flip cover 13 is clamped on the box body 10 through the clamping component 50. A plurality of first air holes 14 are provided on the side walls of both sides of the box body 10, and a accommodating cavity 15 is provided on the box body 10. The hole-shielding component 20 is used to adjust the speed of fragrance emission from the scented paper sheet body 11.

[0031] When the user places the scented sheet body 11, he opens the flip cover 13, puts the scented sheet body 11 into the accommodating cavity 15 from the discharge port 12, covers the flip cover 13 through the snap-fit ​​assembly 50, and adjusts the speed of fragrance emission from the scented sheet body 11 through the hole-covering assembly 20, thereby adjusting the fragrance concentration in the car and reducing waste.

[0032] Reference Figure 4-Figure 5 The snap-on assembly 50 includes an L-shaped connection block 51, a first limit block 52 and a second limit block 53. The first limit block 52 is arranged on the box body 10. One end of the L-shaped connection block 51 is installed on the flip cover 13, and the other end is connected to the second limit block 53. The first limit block 52 abuts against the second limit block 53.

[0033] When it is necessary to open the flip cover 13, the flip cover 13 is flipped toward the side away from the box body 10, and the first limit block 52 and the second limit block 53 abutting against each other are compressed until the flip cover 13 is taken out; when it is necessary to cover the flip cover 13, the flip cover 13 is flipped toward the side close to the box body 10, the first limit block 52 and the second limit block 53 abut against each other, and the flip cover 13 is continued to be flipped, and the first limit block 52 and the second limit block 53 are compressed until the flip cover 13 is covered; when the box body 10 collides due to improper use during daily carrying, the first limit block 52 and the second limit block 53 abut against each other, so that the flip cover 13 is stuck on the box body 10, and it is difficult to detach from the box body 10, and the scented sheet body 11 in the box body 10 is difficult to be exposed to the outside of the box body 10, thereby reducing the probability of the scented sheet body 11 falling from the discharge port 12 to the outside of the box body 10 and causing damage due to collision.

[0034] Reference Figure 1-Figure 3 The connecting component 40 includes a connecting plate 41, a first clamping plate 42 and a second clamping plate 43. The connecting plate 41 is arranged on the box body 10. The first clamping plate 42 and the second clamping plate 43 are symmetrically and obliquely arranged on the connecting plate 41. A clamping cavity 44 is formed between the first clamping plate 42, the second clamping plate 43 and the connecting plate 41. The first clamping plate 41 and the second clamping plate 42 are both made of elastic material.

[0035] When installing the scented sheet on the air plate of the vehicle air conditioner, make the first clamping plate 42 and the second clamping plate 43 contact with the air plate of the vehicle air conditioner, and then squeeze the box body 10 towards the air plate so that the side edges of the two connecting clamping plates are respectively located on both sides of the air plate. As the box body 10 approaches the air plate, the air plate enters the clamping cavity 44, and the clamping surfaces of the first clamping plate 42 and the second clamping plate 43 abut against the side wall of the air plate and move in directions away from each other. The first clamping plate 42 and the second clamping plate 43 clamp the air plate under their own elastic action, so that the box body 10 is fixedly clamped on the air plate; therefore, the setting of the connecting plate 41, the first clamping plate 42 and the second clamping plate 43 makes it convenient for the user to clamp the scented sheet on the air plate of the vehicle air conditioner, and it is difficult to shake during use, difficult to disturb the driver's driving, and not easy to have driving safety hazards.

[0036] Reference Figure 2-Figure 3 A first guide surface 45 is formed between an end surface of the first clamping plate 42 away from the connecting plate 41 and an end surface close to the second clamping plate 43 , and a second guide surface 46 is formed between an end surface of the second clamping plate 43 away from the connecting plate 41 and an end surface close to the first clamping plate 42 .

[0037] When installing the scented sheet on the air plate of the vehicle air conditioner, align the first guide surface 45 and the second guide surface 46 with the air plate, press the box body 10 lightly, the air plate abuts against the first guide surface 45 and the second guide surface 46, and the first clamping plate 42 and the second clamping plate 43 are forced to move in the direction away from each other at one end away from the connecting plate 41 until the air plate is inserted into the clamping cavity 44. The first clamping plate 42 and the second clamping plate 43 clamp the box body 10 on the air plate under the action of elastic force; therefore, the setting of the first guide surface 45 and the second guide surface 46 further facilitates the user to place the air plate into the clamping cavity 44, so that the box body 10 can be more conveniently clamped and installed on the air plate.

[0038] Reference Figure 2-Figure 3 The hole-shielding assembly 20 includes a first baffle 21 and a second baffle 22, which are disposed in the accommodating cavity 15 and slideably fit with the side walls of the accommodating cavity 15. A plurality of second air holes 23 are disposed on the first baffle 21 and the second baffle 22. A control structure 30 for controlling the sliding position of the first baffle 21 and the second baffle 22 is disposed on the box body 10, and the fragrance passes through the first air hole 14 and the second air hole 23 and is emitted to the outside of the box body 10.

[0039] After the scented sheet is placed in the box body 10, the fragrance emitted from the scented sheet passes through the first air hole 14 and the second air hole 23 and is emitted to the outside of the box body 10. When the fragrance in the car is too strong, the control structure 30 is used to adjust the sliding position of the first baffle 21 and the second baffle 22 to reduce the size of the overlapping surface of the first air hole 14 and the second air hole 23, thereby achieving the effect of reducing the fragrance emission speed, thereby achieving the effect of reducing the fragrance concentration in the car; if it is not necessary to emit fragrance anymore, the control structure 30 can be used to adjust the sliding position of the first baffle 21 and the second baffle 22 to make the first air hole 14 and the second air hole 23 have no overlapping surface, the fragrance is sealed in the box body 10, and it is difficult to emit to the outside of the box body 10, so that the effect of no longer emitting fragrance can be achieved. When the fragrance in the car is too weak, the control structure 30 is used to adjust the sliding position of the first baffle 21 and the second baffle 22, so that the size of the overlapping surface of the first air hole 14 and the second air hole 23 is increased, so as to increase the fragrance emission speed, thereby achieving the effect of increasing the fragrance concentration in the car; therefore, the first baffle 21, the second baffle 22 and the control structure 30 are set. Since the fragrance emission speed is proportional to the size of the overlapping surface, the user can control the sliding position of the first baffle 21 and the second baffle 22 through the control structure 30, thereby controlling the size of the overlapping surface between the first air hole 14 and the second air hole 23, and achieving the effect of controlling the fragrance emission speed on the scented sheet body 11, thereby being able to adjust the fragrance concentration in the car and reduce waste.

[0040] Reference Figure 2-Figure 3 A plurality of partitions 16 are arranged in the accommodating cavity 15 . The partitions 16 are arranged on both sides of the scented sheet body 11 . The partitions 16 are arranged between the first baffle 21 and the second baffle 22 , and are attached to the side wall of the first baffle 21 or the second baffle 22 .

[0041] When placing the scented sheet body 11, open the flip cover 13, put the scented sheet body 11 into the accommodating cavity 15 from the discharge port 12, and place the scented sheet body 11 between multiple partitions 16. Cover the flip cover 13 through the snap-on assembly 50. Therefore, the setting of the partition 16 makes it difficult for the scented sheet body 11 to contact the first baffle 21 or the second baffle 22. When the user moves the first baffle 21 or the second baffle 22, it is difficult for the first baffle 21 or the second baffle 22 to have relative friction with the scented sheet body 11, thereby reducing the wear of the first baffle 21 or the second baffle 22 on the scented sheet body 11 during the movement; and multiple partitions 16 are in contact with the side walls of the first baffle 21 or the second baffle 22, which is used to reduce the frequency of shaking of the first baffle 21 or the second baffle 22 during the movement.

[0042] Reference Figure 2-Figure 3The control structure 30 includes a screw 31 and a threaded sleeve 32. The screw 31 is rotatably connected to the box body 10. The box body 10 is slidably connected to the threaded sleeve 32 by opening a sliding groove 17. The first baffle 21 and the second baffle 22 are both fixedly connected to the threaded sleeve 32.

[0043] After the scented sheet body 11 is placed in the box body 10, when it is necessary to adjust the speed of the fragrance emission from the scented sheet body 11, the screw 31 is rotated, the threaded sleeve 32 moves along the length direction of the screw 31, the first baffle 21 and the second baffle 22 move, and their sliding positions change. The size of the overlapping surface between the first air hole 14 and the second air hole 23 changes, and the speed of the fragrance emission from the scented sheet body 11 is controlled to change, thereby achieving the effect of controlling the speed of the fragrance emission from the scented sheet body 11. Therefore, the setting of the screw 31 and the threaded sleeve 32 allows the user to control the sliding position of the first baffle 21 and the second baffle 22 by rotating the screw 31, and the operation is simple and convenient.

[0044] Reference Figure 2-Figure 4 One end of the screw rod 31 is rotatably mounted on the box body 10 , and the other end is extended to the outside of the box body 10 and fixedly connected with a knob 33 .

[0045] During the process of wiping with an eraser, when it is necessary to control the rotation of the screw 31, the knob 33 is turned to control the rotation direction of the screw 31, and the sliding position of the first baffle 21 and the second baffle 22 is controlled by the threaded sleeve 32. Therefore, the setting of the knob 33 is convenient for the user to control the sliding position of the first baffle 21 and the second baffle 22 through the screw 31 and the threaded sleeve 32, thereby adjusting the size of the overlapping surface between the first air hole 14 and the second air hole 23, and achieving the effect of controlling the diffusion speed of the fragrance on the scented sheet body 11.

[0046] The implementation principle of a hard and non-deformable scent paper sheet in this embodiment is as follows:

[0047] When placing the scented tablet body 11, flip the cover 13 toward the side away from the box body 10, the first limit block 52 and the second limit block 53 abutting against each other are compressed until the cover 13 is opened, and the scented tablet body 11 is placed into the accommodating cavity 15 from the discharge port 12, and the scented tablet body 11 is placed between the multiple partitions 16; flip the cover 13 toward the side close to the box body 10, the first limit block 52 abuts against the second limit block 53, continue to flip the cover 13, the first limit block 52 and the second limit block 53 are compressed until the cover 13 is closed; align the first guide surface 45 and the second guide surface 46 with the wind plate, press the box body 10 lightly, the wind plate abuts against the first guide surface 45 and the second guide surface 46, and the first clamping plate 42 The first and second clamping plates 42 and 43 are forced to move in the direction away from each other at one end away from the connecting plate 41 until the wind plate is stuck in the clamping cavity 44. The first and second clamping plates 42 and 43 clamp the box body 10 on the wind plate under the action of their own elastic force, making it difficult to shake. Turn the knob 33 to control the rotation direction of the screw 31, and control the sliding position of the first baffle 21 and the second baffle 22 through the threaded sleeve 32, so as to control the size of the overlapping surface between the first air hole 14 and the second air hole 23. The speed of fragrance dissipation is proportional to the size of the overlapping surface. Therefore, the user can control the speed of fragrance dissipation on the fragrance sheet body 11 by turning the knob 33, so as to adjust the fragrance concentration in the car and reduce waste.

[0048] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
