The friction part 202 is adapted to make the first limiting surface 2021 abut against the second limiting surface 403 when in the first position, and to make the first limiting surface 2021 separate from the second limiting surface 403 when in the second position.

The fourth limiting surface 4041 is located on the elastic buckle 404, and the elastic buckle 404 is adapted to be deformed to pass through the through hole 114 and enter the through hole 113. In other embodiments, the pressing member 40 can be fixed with the body 201 as a whole.

[0062] The counterweight 60 is installed on the side of the base 14 away from the mounting member to provide sufficient stability. The counterweight 60 can be installed with the base 14 as a whole through screws.

[0063] During installation, first, the clamping member 12 is inserted into the hollow hole of the base 14 to make the fifth limiting surface 121 abut against the sixth limiting surface 142. The second biasing member 50 is sleeved on the clamping member 12 and is seated on the base 14. The main pipe 11 is sleeved on the second biasing member 50 and makes the third limiting surface 115 abut against the second biasing member 50. Then, the main pipe 11 and the clamping member 12 are locked through screws. The first biasing member 30 and the body 201 of the friction member 20 are installed in the installation groove 131 of the docking member 13, and then the docking member 13 is installed on the main pipe 11. Then, the pressing member 40 is installed so that the elastic buckle 404 of the pressing member 40 passes through the through hole 114 and reaches the through hole 113. Finally, the counterweight 60 is installed on the side of the base 14 away from the mounting member, and the installation is completed.

[0064] In use, the spray bottle 70 is placed into the mounting hole 112, the bottle body of the spray bottle 70 is seated on the support surface 401, the pressing end of the spray bottle 70 is placed into the accommodation slot 402, the other end of the spray bottle 70 is pressed to be flush with the opening of the mounting hole 112, the pressing member 40 is forced to move downward, and the friction portion 202 is deformed, the friction portion 202 enters the mounting slot 131 and abuts against the side wall of the mounting slot 131, the first biasing member 30 stores energy, at this time, the force of the first biasing member 30 on the friction member 20 is equal to the friction force of the friction portion 202 and the side wall of the mounting slot 131 + the gravity (the gravity of the friction member 20, the pressing member 40 and the spray bottle 70), the friction member 20 is parked at the first position, and the first limiting surface 2021 abuts against the second limiting surface 403. When the spray bottle 70 needs to be used, the spray bottle 70 is pressed, the force of the first biasing member 30 on the friction member 20 is greater than the friction force of the friction portion 202 and the side wall of the mounting slot 131 + the gravity, the energy of the first biasing member 30 on the body 201 is released to make the friction portion 202 move to the second position, so as to drive the pressing member 40 and the spray bottle 70 to pop up, and the spray bottle 70 is popped out to be exposed at the opening of the mounting hole 112 and can be taken.

[0065] Compared with the prior art, the embodiment has the following beneficial effects:

[0066] In an exemplary embodiment, a pressing and bouncing mechanism includes a housing 10, a friction member 20 and a first biasing member 30.

[0067] The housing 10 is provided with a mounting slot 131 for mounting the friction member 20.

[0068] The friction member 20 is provided with a body 201 and a friction portion 202 connected with each other, the friction portion 202 protrudes from the body 201 along the central axis away from the body 201, the friction portion 202 is adapted to be placed into the mounting slot 131 and parked at the first position abutting against the side wall of the mounting slot 131, and the parking of the two is realized by the abutting friction force between the friction portion 202 and the side wall of the mounting slot 131. The friction portion 202 is also adapted to be located at the second position disengaged from the side wall of the mounting slot 131, so as to realize the change of the two positions of the friction member 20.

[0069] The two ends of the first biasing member 30 are respectively applied to the bottom of the mounting groove 131 and the body 201, and are adapted to store energy when the body 201 moves towards the bottom of the mounting groove 131, so as to adjust the force applied to the body 201 in the process; when the friction portion 202 is at the first position and further moves towards the bottom of the mounting groove 131, the energy of the first biasing member 30 to the body 201 is released to make the friction portion 202 move to the second position; when the first biasing member 30 applies force to the body 201, the friction force and the gravity of the friction member 20 are balanced at the first position, and when the friction portion 202 further moves towards the bottom of the mounting groove 131 at the first position, the force applied by the first biasing member 30 to the body 201 increases, which is sufficient to be greater than the friction force and the gravity of the friction member 20 (and other forces applied to the friction member 20, such as gravity), so as to cause the friction member 20 to be located at the second position. The mechanism can realize the pressing switching of the two positions, and the structure is simpler, the processing is simple, and the service life is long.

[0070] In an exemplary embodiment, when the friction portion 202 is at the first position and further moves towards the bottom of the mounting groove 131, the contact area between the friction portion 202 and the side wall of the mounting groove 131 no longer increases, so that the friction force between the friction portion 202 and the side wall of the mounting groove 131 no longer increases, thereby making the friction member 20 more easily move to the second position under the action of the first biasing member 30.

[0071] In an exemplary embodiment, the friction portion 202 is inclined away from the bottom of the mounting groove 131, and the friction portion 202 is adapted to cooperate with the bevel of the edge of the mounting groove 131 to make the friction portion 202 enter the mounting groove 131 and stop at the first position abutting against the side wall of the mounting groove 131, and vice versa. When the friction portion 202 is at the second position, the normal inclined state is restored. Through the inclination of the friction portion 202, the force generated by the deformation recovery of the friction portion 202 during the sliding from the second position to the first position can assist the movement to the second position, so that the friction member 20 is more easily moved to the second position, and when the friction portion 202 is at the first position, the friction portion 202 has a tendency of deformation recovery, which applies force to the side wall of the mounting groove 131 and increases the friction force between the two, thereby preventing the friction member 20 from being easily ejected by the first biasing member 30 and keeping the stop.

[0072] In an exemplary embodiment, the pressing member 40 is adapted to press against the body 201 when pressed to make the friction portion 202 be at the first position or the second position, and the sliding of the friction member 20 is realized by the pressing member 40 applying force to the body 201, so as to make the friction portion 202 switch between the first position and the second position. Through the power transmission of the pressing member 40, the force arm can be increased, so that when the friction member 20 is not good to be applied with force, the pressing force applied by the user can still be accepted.

[0073] In an exemplary embodiment, the pressing member 40 is pressed against the body 201 and is adapted to be separated from the body 201. The friction part 202 is provided with a first limiting surface 2021, and the pressing member 40 is provided with a second limiting surface 403 facing away from the body 201. When the friction part 202 is in the first position, the first limiting surface 2021 abuts against the second limiting surface 403, thereby preventing the pressing member 40 from being ejected due to vibration or the like. When the friction part 202 is in the second position, the first limiting surface 2021 is separated from the second limiting surface 403, and the friction part 202 no longer limits the position of the pressing member 40, allowing the pressing member 40 to be separated from the body 201, thereby facilitating ejection.

[0074] In an exemplary embodiment, the shell 10 is provided with a mounting hole 112 and a third limiting surface 115 facing away from the hole of the mounting hole 112. The pressing end of the pressing member 40 faces the hole of the mounting hole 112. The pressing member 40 is provided with a fourth limiting surface 4041 adapted to abut against the third limiting surface 115, thereby limiting the position of the pressing member 40 and preventing the pressing member 40 from being separated from the shell 10, ensuring the stability of the structure.

[0075] In an exemplary embodiment, the shell 10 is further provided with a mounting hole 112 adapted to accommodate the spray bottle 70, thereby achieving hidden installation of the spray bottle 70. The pressing member 40 is provided with a supporting surface 401 facing the mounting hole 112 and a displacement slot 402 located in the supporting surface 401. The supporting surface 401 is adapted to support the spray bottle 70, and the displacement slot 402 is adapted to accommodate the pressing end of the spray bottle 70, thereby preventing the pressing end of the spray bottle 70 from being pressed when the spray bottle 70 is pressed to switch the position of the friction part 20, and preventing liquid in the spray bottle 70 from being sprayed out, thereby preventing waste.

[0076] In an exemplary embodiment, the shell 10 includes a mounting member and a base 14. The mounting member is provided with a mounting slot 131, and the projection area of the base 14 is greater than the projection area of the mounting member, thereby providing stability.

[0077] The second biasing member 50 acts on the mounting member and the base 14 at both ends to apply an upward force to the mounting member. The mounting member is provided with a fifth limiting surface 121 facing upward, and the base 14 is provided with a sixth limiting surface 142 adapted to cooperate with the fifth limiting surface 121, thereby providing a cushioning force to the mounting member, preventing the structure at the mounting slot 131 from being damaged when the mounting member or the base 14 is impacted, and improving the service life.

[0078] In an exemplary embodiment, the counterweight 60 is mounted on the base 14, further improving the stability of the base 14 and enabling the base 14 to better support the mounting member.

[0079] In an exemplary embodiment, a paper towel holder includes the press-and-spring mechanism, the housing 10 is provided with a support portion 141 and a rod portion 111, the paper towel 80 is adapted to be sleeved on the rod portion 111, and the support portion 141 is adapted to support the paper towel 80 and has the effect of the press-and-spring mechanism.
