Technical Field

[0001] This utility model belongs to the field of venetian blind cleaning technology, and relates to a venetian blind brush with a convenient brush head replacement. Background Technology

[0002] Venetian blinds are favored for their superior performance and are widely used in office buildings, residential buildings, and some public buildings. However, due to their unique structure, cleaning Venetian blinds has become a major challenge. Traditionally, dust is cleaned using brushes, but traditional brushes have drawbacks:

[0003] Traditional sieves have fixed brush heads. After prolonged use, the cleaning cloth on the brush surface will wear out and need to be replaced. However, the fixed brush structure makes replacement difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a venetian blind brush with a convenient brush head replacement, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A louver brush with easy brush head replacement includes a back plate, a brush head, a mounting base, and a mounting rod. The back plate has multiple mounting bases on its surface, and the mounting rod is located at the center of each mounting base. The brush head is sleeved on the outside of the mounting rod. A side sliding groove is provided on the outside of the mounting base, and a movable arm is movably mounted inside the side sliding groove. A positioning plug is connected to the front end of the movable arm.

[0007] In the aforementioned louver brush that facilitates brush head replacement, the outer wall surface of the mounting rod is provided with multiple elastic protrusions.

[0008] In the aforementioned louver brush that facilitates brush head replacement, the tail end of the brush head is provided with a locking head, the inside of which is provided with a positioning hole, and the positioning plug is inserted into the inside of the positioning hole.

[0009] In the aforementioned louver brush that facilitates brush head replacement, the outer wall of the fixing base is provided with a locking groove, and the locking head is inserted into the locking groove.

[0010] In the aforementioned louver brush that facilitates brush head replacement, a handle is provided on the side of the back plate, and an anti-slip rubber sleeve is provided on the outside of the handle.

[0011] In the aforementioned louver brush that facilitates brush head replacement, a push button is connected to one side of the middle portion of the movable arm. The surface of the push button is provided with anti-slip texture. A sponge sleeve is fitted over the brush head, and a cleaning cloth is provided over the outside of the sponge sleeve.

[0012] Compared with the prior art, the advantages of this utility model of a venetian blind brush with a convenient brush head replacement are:

[0013] This application features a detachable brush head structure with a locking head at the tail end. A mounting base and a mounting rod are installed on the back plate. During installation, the brush head is slipped onto the mounting rod, where multiple elastic protrusions provide anti-slip restraint. The brush head is pushed until its tail end contacts the mounting base, and the locking head at the tail end inserts into the locking groove. Then, the push button is pushed, causing the moving arm to slide within the side groove, allowing the positioning plug at one end of the moving arm to insert into the positioning hole inside the locking head, thus restraining the locking head. The brush head is stably mounted on the rod thanks to the positioning plug and the elastic protrusions. For disassembly, the positioning plug is released, and the brush head is pulled outwards. This design facilitates brush head replacement and installation, enhancing practicality. Attached Figure Description

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] A louver brush with easy brush head replacement includes a back plate 1, a brush head 3, a fixing base 4, and a mounting rod 11. The back plate 1 has multiple fixing bases 4 on its surface. The mounting rod 11 is located at the center of the fixing base 4. The brush head 3 is sleeved on the outside of the mounting rod 11. The fixing base 4 has a side sliding groove 13 on its outer side. A movable arm 8 is movably arranged inside the side sliding groove 13. The front end of the movable arm 8 is connected to a positioning plug 7. The movable arm 8 has an arc-shaped structure. When the movable arm 8 slides, it has a certain damping. When there is no external force, it will not slide naturally under friction.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a louver brush with a convenient brush head replacement. Specifically, the outer wall surface of the mounting rod 11 is provided with multiple elastic protrusions 12, which are rubber protrusions and mainly provide frictional limiting for the brush head 3.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a louver brush with a convenient brush head replacement. Specifically, the tail end of the brush head 3 is provided with a locking head 5, and the locking head 5 has a positioning hole 6 inside, and the positioning plug 7 is inserted into the positioning hole 6.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a louver brush with a convenient brush head replacement. Specifically, the outer wall of the fixing base 4 is provided with a slot 10, and the slot head 5 is inserted into the slot 10.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model provides a louver brush with a convenient brush head replacement. Specifically, a handle 2 is provided on the side of the back plate 1, and an anti-slip rubber sleeve is provided on the outside of the handle 2. When cleaning, the handle 2 is held for cleaning.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model discloses a louver brush with a convenient brush head replacement. Specifically, a push button 9 is connected to one side of the middle of the movable arm 8. The surface of the push button 9 is provided with anti-slip texture. A sponge sleeve is fitted over the brush head 3, and a cleaning cotton cloth is placed on the outside of the sponge sleeve. The brush head 3 is hollow inside. The sponge sleeve is directly fitted over the outside of the brush head 3, and the sponge sleeve and the cleaning cotton cloth are in direct contact with the fan blades for cleaning. The sponge sleeve and the cleaning cotton cloth are commercially available devices known to those skilled in the art. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0028] This utility model discloses a venetian blind brush with a convenient brush head replacement. A locking head 5 is provided at the tail end of the brush head 3. A fixing base 4 and a mounting rod 11 are installed on the back plate 1. When installing the brush head 3, it is placed on the mounting rod 11. The brush head 3 is prevented from slipping and is limited by multiple elastic protrusions 12. The brush head 3 is pushed until its tail end contacts the fixing base 4, and the locking head 5 at the tail end of the brush head 3 is inserted into the locking groove 10. Then, the push button 9 is pushed, causing the moving arm 8 to slide in the side groove. The internal sliding mechanism 13 allows the positioning plug 7 at one end of the moving arm 8 to be inserted into the positioning hole 6 inside the locking head 5, thereby limiting the locking head 5. The brush head 3 can be stably installed on the rod body through the limiting of the positioning plug 7 and the elastic protrusion 12. When disassembling, first push the moving arm 8 towards the rear to make the positioning plug 7 come out from the positioning hole 6, release the limiting of the positioning plug 7, and then slowly pull out the brush head 3 directly towards the outside. In this way, the brush head 3 is easy to replace and install, and its practicality is higher.
