Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to an automatic replacement device for a filter screen of a dehumidifier. Background Art

[0002] The patent published (announcement) number CN213300322U on the China Patent Network discloses a dehumidifier with a replaceable filter, which drives the winding shaft to rotate through a servo motor to reel in the filter, and reels the surface-contaminated filter into the interior of the installation box, while the clean filter corresponds to the air intake part, thereby achieving the purpose of automatically replacing the filter without stopping the dehumidifier. However, during the operation of the dehumidifier, humid air will always be drawn from the outside, that is, a high-frequency air flow will always be generated inside the dehumidifier, while the contaminated part of the filter will still be reeled in the body. During the reeling process, the dust intercepted on the front side of the filter will also come into contact with the back side of the filter. Under the air flow, the intercepted dust can easily enter the equipment, which has disadvantages. For this reason, we propose an automatic replacement device for the dehumidifier filter.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-4 The utility model provides a technical solution: an automatic replacement device for a dehumidifier filter, comprising a filter 2 arranged inside a body, the filter 2 being in a roll shape, and further comprising:

[0020] The clamping and conveying mechanism 3 is installed in the machine body and connected to the filter screen 2. The clamping and conveying mechanism 3 replaces the position of the contaminated part of the filter screen 2 with the clean part of the filter screen 2;

[0021] A support plate 4 is fixed in the machine body, and a hole 41 is formed on the support plate 4, and the filter screen 2 penetrates the hole 41;

[0022] A cutting mechanism 5, which is mounted on the support plate 4 and connected to the filter screen 2. After the clamping and conveying mechanism 3 is operated, the cutting mechanism 5 separates the contaminated part of the filter screen 2 from other parts;

[0023] The recovery box 6 is installed through the machine body, and the top end is in contact with the support plate 4, and there is a gap connection between the recovery box 6 and the machine body.

[0024] The clamping and conveying mechanism 3 includes a motor 31 installed on the body, a shaft 1 32 is installed on the motor 31, the shaft 1 32 passes through the filter 2 and is fixed to one end of the filter 2, a shaft 2 33 is installed on the body, a gear 1 34 is sleeved on the shaft 1 32 and the shaft 2 33, a chain 35 is connected between the gears 1 34, a shaft 36 is installed on the body, a gear 2 37 is sleeved on the shaft 3 36 and the shaft 2 33, the gears 2 37 are meshed with each other, a roller 38 is sleeved and fixed on the shaft 2 33 and the shaft 3 36, and the roller 38 is respectively tightly attached to one end of the filter 2.

[0025] The rollers 38 are all rubber cylinders.

[0026] The rubber tube clamps the filter screen 2 more submerged, and has a better fixing effect. When the filter screen 2 is driven to be replaced, the greater friction force makes it easier to replace the filter screen 2.

[0027] The cutting mechanism 5 comprises a fixing plate 51 mounted on the supporting plate 4 , a cutting opening 52 is arranged on the fixing plate 51 , an electric push rod 53 is mounted on the supporting plate 4 , and a cutting knife 54 is mounted on the electric push rod 53 .

[0028] A limiting block 60 is fixed in the body, and there are two limiting blocks 60 , which are respectively arranged on both sides of the filter screen 2 , and a sliding groove 61 is formed on each of the limiting blocks 60 .

[0029] The track of the filter 2 during replacement is restricted to prevent the filter 2 from shifting.

[0030] The working principle of the utility model is as follows: when there is a lot of dust on the filter screen 2 or it needs to be replaced, the motor 31 is turned on, the motor 31 drives the shaft 1 32 to rotate, the rotation of the shaft 1 32 drives the shaft 2 33 to rotate synchronously through the chain 35, and the shaft 2 33 drives the shaft 3 36 to rotate in the opposite direction through the gear 2 37, and synchronously drives the corresponding roller 38 to rotate in the opposite direction. At this time, the filter screen 2 clamped by the roller 38 is driven by the roller 38, and the filter screen 2 wrapped on the shaft 1 32 is released. The rotation of the shaft 1 32 makes this process easier and effectively prevents the roller 38 from pulling the filter screen 2 apart. After the filter screen 2 is replaced, the contaminated filter screen 2 falls into the recovery box 6 under the action of the roller 38 and gravity. At this time, the electric push rod 53 is turned on, and the electric push rod 53 drives the cutting knife 54 to approach the filter screen 2. When the cutting knife 54 and the cutting opening 52 overlap, the filter screen 2 is cut. At this time, the user can pull out the recovery box 6 to deal with the contaminated filter screen 2.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
