Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a cold evaporative humidifier. Background Art

[0002] The cold evaporative humidifier is a device that uses the principle of natural evaporation to humidify. It uses a built-in high-speed motor to drive the fan to rotate at high speed, so that the water in the water tank is sucked to the evaporation filter under the action of atmospheric pressure and the water absorber. The water is transformed into fine droplets on the evaporation filter, and these droplets are sent to the mist outlet through the air duct of the air inlet. At the mist outlet, the droplets merge with the high-speed air flow generated by the motor to form aerosol. As the high-speed aerosol contacts the residual heat in the air, the droplets are completely vaporized, thus achieving a humidification effect.

[0003] However, existing cold evaporative humidifiers usually need to be placed on the ground or on a table, and their stability may be affected by the placement environment. If the humidifier is placed on an unstable table or edge, it is easy to fall from a height once it is hit or vibrated by external force, which is not practical enough.

[0004] In view of the above problems, the utility model proposes a cold evaporative humidifier. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model discloses a cold evaporative humidifier, the suction cup body is pressed to discharge the internal air, and the pressure difference is used for adsorption. After the internal air is discharged, the control part is rotated, and the control part is used to drive the threaded rod to rotate, so that the top block body is moved upward on the outer wall of the threaded rod through the cooperation of the side connecting block, so that the top block body pushes the sealing part, drives the shape of the expansion cavity to deform, and drives the edge area of ​​the sealing part to become larger through the air pressure. When the control part cannot be rotated, the sealing part can completely seal the opening. When the fixation of the suction cup body is released, it is only necessary to rotate the control part in the opposite direction so that the top block body no longer pushes the sealing part. At this time, the sealing part returns to its original state, and the external air can enter the installation groove and then enter the suction cup body from the vent hole, so that the fixation can be released.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 In order to solve the problem that the existing cold evaporative humidifier usually needs to be placed on the ground or on a table, and its stability may be affected by the placement environment, if the humidifier is placed on an unstable table or edge position, once it is hit or vibrated by external force, it is easy to fall from a high place, and the practicality is insufficient, the following preferred technical solutions are provided:

[0024] A cold evaporative humidifier comprises a humidifier body 1, and a rotating control disk 2 installed at the lower end of the humidifier body 1, the lower end of the rotating control disk 2 is fixedly connected to a support plate 3, the lower end of the support plate 3 is installed with a fixed disk assembly 4, the fixed disk assembly 4 comprises a suction cup body 41, and a control member 42 rotatably connected to the upper wall of the suction cup body 41, the upper end of the suction cup body 41 is provided with a mounting groove 43, the inner bottom plate of the mounting groove 43 is provided with a vent hole 44, the inner bottom plate of the mounting groove 43 is rotatably connected with a threaded rod 45, the upper end of the threaded rod 45 is fixedly connected to the control member 42, the outer wall of the threaded rod 45 is threadedly connected with a top block body 46, and the upper end of the top block body 46 is abutted with a sealing member 48.

[0025] Side blocks 47 are fixedly connected to both sides of the top block body 46, and the side blocks 47 are slidably connected to the inner wall of the mounting groove 43. The end of the sealing member 48 away from the bottom plate of the mounting groove 43 is fixedly connected to the control member 42. The diameter of the sealing member 48 is equal to the opening diameter of the mounting groove 43, and the diameter of the control member 42 is larger than the opening diameter of the mounting groove 43. The top block body 46 always abuts against the lower wall of the sealing member 48.

[0026] The seal 48 is disc-shaped and is a component made of rubber material. An expansion cavity 49 is opened inside the seal 48. A rubber bent rod 410 is fixedly connected between the top plate and the bottom plate in the expansion cavity 49. There are multiple groups of rubber bent rods 410, which are evenly arranged and distributed in the expansion cavity 49.

[0027] Specifically, the humidifier body 1 can be rotated by rotating the control disk 2 to adjust the position. When installing the humidifier body 1, it is necessary to press the suction cup body 41 to discharge the internal air and use the pressure difference for adsorption. After the internal air is discharged, the control member 42 is rotated, and the control member 42 is used to drive the threaded rod 45 to rotate, so that the top block body 46 moves up on the outer wall of the threaded rod 45 through the cooperation of the side connecting block 47, so that the top block body 46 pushes the sealing member 48, drives the shape of the expansion cavity 49 to deform, and drives the edge area of ​​the sealing member 48 to increase through the air pressure. When the control member 42 cannot be rotated, the sealing member 48 can completely seal the opening. To release the fixation of the suction cup body 41, it is only necessary to rotate the control part 42 in the opposite direction so that the top block body 46 no longer pushes up the sealing part 48. At this time, the sealing part 48 returns to its original state, and the outside air can enter the mounting groove 43, and then enter the suction cup body 41 from the vent hole 44, and the fixation can be released. The operation is convenient, and the suction cup body 41 is stably fixed, and it is not easy to fall due to external force. This solves the problem that the existing cold evaporative humidifier usually needs to be placed on the ground or on a table, and its stability may be affected by the placement environment. If the humidifier is placed on an unstable table top or edge position, once it is hit or vibrated by external force, it is easy to fall from a high place, resulting in insufficient practicality.

[0028] When the seal 48 is pushed up by the top block body 46, the rubber curved rod 410 will also bend under pressure. Therefore, when the top block body 46 no longer pushes up the seal 48, the self-restoration of the seal 48, combined with the support of the rubber curved rod 410 in the bent state, can make the seal 48 quickly return to its original state, with significant effect.

[0029] Working principle: Press the suction cup body 41 to expel the internal air and use the pressure difference for adsorption. After the internal air is expelled, rotate the control member 42, and use the control member 42 to drive the threaded rod 45 to rotate, so that the top block body 46 moves up on the outer wall of the threaded rod 45 through the cooperation of the side block 47, so that the top block body 46 pushes the sealing member 48, causing the shape inside the expansion cavity 49 to deform, and the edge area of ​​the sealing member 48 to increase through air pressure. When the control member 42 cannot be rotated, the sealing member 48 can completely seal the opening. When the suction cup body 41 is released, it is only necessary to rotate the control member 42 in the opposite direction so that the top block body 46 no longer pushes the sealing member 48. At this time, the sealing member 48 returns to its original state, and the outside air can enter the mounting groove 43, and then enter the suction cup body 41 from the vent hole 44 to release the fixation.
