Technical Field
[0001] This utility model belongs to the technical field of duster structure, specifically referring to a duster with dual wiping heads. Background Technology
[0002] Dust dusters typically have a single brush head, making it impossible to simultaneously wipe both sides of ceiling fan blades or other similar objects. Therefore, to address this issue, dust dusters with two wiping heads have emerged on the market. These two heads can rotate relative to each other, thus accommodating a wider range of wiping scenarios.
[0003] For example, Chinese patent CN202420075374.9 describes a duster, including a base, a first mounting part and a second mounting part for mounting a wiping cloth. The first mounting part is rotatably connected to the base, and the first mounting part is rotatably connected to the second mounting part. After the first mounting part and the second mounting part are rotated to the horizontal direction, they extend out of the base. This duster can clean dust after the wiping cloth is installed on the two mounting parts. When the two mounting parts are flipped to the same side, the first and second mounting parts can clamp the fan blades, thus wiping both sides simultaneously. This product is convenient for users and achieves multi-functional cleaning. However, it also has some shortcomings: when the first and second mounting parts are flipped to the same side, there is a gap between them, preventing them from fitting together. The same disposable wiping cloth cannot be inserted into both the first and second mounting parts simultaneously; each mounting part requires an independent disposable wiping cloth, resulting in waste of disposable wiping cloth during cleaning. Summary of the Invention
[0004] The purpose of this invention is to provide a duster with multiple wiping states.
[0005] The purpose of this utility model is achieved as follows:
[0006] A duster with dual wiping heads includes a handle, a connecting seat fixed to the end of the handle, a fixed seat rotatably mounted on the connecting seat, and a first wiping head fixedly or integrally mounted on the fixed seat; a mounting cavity is provided in the middle of the fixed seat, and the connector of the second wiping head is sleeved in the mounting cavity and can rotate and move up and down by means of the mounting cavity; the first wiping head and the second wiping head are arranged in parallel.
[0007] Rotate the second wiping head above the first wiping head and keep it in the stacked state; the duster is in the first wiping state.
[0008] Rotate the second wiping head above the first wiping head and keep the first and second wiping heads at a distance, so that the duster is in the second wiping state;
[0009] Rotate the second wiping head to the side of the first wiping head. The first and second wiping heads are arranged left and right, and the duster is in the third wiping state.
[0010] Furthermore, the duster proposed in this utility model also has the following features: a locking element is provided between the connector and the mounting cavity. When the locking element is active, the duster remains in a first wiping state, a second wiping state, or a third wiping state. The locking element is a spring-loaded buckle, and a limiting part that engages with the spring-loaded buckle is provided on the mounting cavity. When the spring-loaded buckle is held in different limiting parts, the duster remains in the corresponding wiping state.
[0011] Furthermore, the duster proposed in this utility model also has the following features: it includes a pushing member connected to a locking member, the pushing member can disengage the locking member from the limiting part, and the second wiping head can move relative to the first wiping head.
[0012] Furthermore, the duster proposed in this utility model also has the following features: the connector is hollow in the middle, and an opening is provided above the hollow cavity. The spring buckle and the pusher are both located in the middle cavity of the connector, and the engaging part of the spring buckle protrudes from the connector and can be connected to the corresponding limiting part.
[0013] Furthermore, the duster proposed in this utility model also has the following features: the pushing member is provided with a first inclined surface, and the snap fastener is provided with a second inclined surface that cooperates with the first inclined surface. When the pushing member is pressed and moved into the middle cavity of the connector, the pushing member pulls the snap fastener inward, thereby separating the engaging part of the snap fastener from the limiting part; or, the pushing member and the snap fastener are connected by a transmission rod. When the pushing member is pressed and moved into the middle cavity of the connector, the snap fastener moves inward under the action of the transmission rod, thereby separating the engaging part of the snap fastener from the limiting part.
[0014] Furthermore, the duster proposed in this utility model also has the following features: a track is provided inside the mounting cavity of the fixed base, and a protrusion is provided on the side of the connector of the second wiping head that is limited within the track, and the connector of the second wiping head moves along the track.
[0015] Furthermore, the duster proposed in this utility model also has the following features: the track is provided with a longitudinal section and a transverse section; when the protrusion moves in the longitudinal section, the second wiping head moves up and down relative to the first wiping head; when the protrusion moves in the transverse section, the second wiping head rotates left and right relative to the first wiping head; when the duster is in the first wiping state or the third wiping state, the protrusion remains at the bottom of the longitudinal section; when the duster is in the second wiping state, the protrusion remains in the transverse section.
[0016] Furthermore, the duster proposed in this utility model also has the following features: two longitudinal sections are symmetrically arranged on both sides of the transverse section, with the transverse section located above the longitudinal section; when the duster switches between the first wiping state and the third wiping state, the second duster needs to move upward, rotate, and move downward in sequence.
[0017] Includes a locking cover, which is fixed above the mounting cavity of the mounting base and prevents the connector of the second wiping head from disengaging from the mounting cavity of the mounting base.
[0018] Furthermore, the duster proposed in this utility model also has the following features: the mounting cavity is provided with a notch on the other side of the first wiping head; when the duster is in the third wiping state, the second wiping head is limited within the notch, and the first wiping head and the second wiping head remain on the same plane.
[0019] The outstanding and beneficial technical effects of this utility model compared to the prior art are:
[0020] 1. This utility model has at least three wiping states. In the first wiping state, the second wiping head and the first wiping head are stacked, and a disposable wiping cloth can be inserted between the second and first wiping heads for routine cleaning. In the second wiping state, the second wiping head is positioned above the first wiping head, maintaining a distance between them. Both the second and first wiping heads can be independently fitted with disposable wiping cloths, simultaneously wiping both sides of ceiling fan blades or other similar objects. In the third wiping state, the first and second wiping heads are arranged side-by-side, and both can be independently fitted with disposable wiping cloths. This state provides a large dust wiping area. Furthermore, the first and second wiping heads are arranged parallel to each other, and the second wiping head can only rotate axially relative to the first wiping head via the mounting cavity. During the user's wiping process, the wiping direction and rotation direction are misaligned, thus the second wiping head is less prone to rotation and has good stability.
[0021] 2. This utility model uses a spring-loaded snap-fit limiting part for positioning. The snap-fit remains in different limiting parts, and the duster remains in the corresponding wiping state. Preferably, the snap-fit is driven by a pusher, which is exposed at the top. The user only needs to press the pusher to separate the snap-fit from the limiting part, and then the user can move the second wiping head. The operation is simple for the user.
[0022] 3. The mounting cavity of this utility model is provided with a track, which limits the movement of the limiting joint, allowing the second wiping head to move in an orderly manner. Preferably, the track has a longitudinal section and a transverse section, with longitudinal sections symmetrically arranged on both sides of the transverse section. By setting this structure, the second wiping head needs to be moved to a higher position before it can move to the first wiping state or the second wiping state. This structure effectively avoids misoperation and makes the first wiping state or the second wiping state more stable.
[0023] 4. In the third wiping state, the second wiping head is confined within the notch on one side of the mounting cavity. This confining of the second wiping head makes the duster more stable in this state, and the confining structure can alleviate the stress on the protrusion and the track, protecting the protrusion from damage. Preferably, when the duster is in the third wiping state, the first and second wiping heads are kept on the same plane. When the user uses it, the disposable wiping cloths installed on the first and second wiping heads are symmetrically arranged on the left and right sides, resulting in a better wiping effect for the user.

Detailed Implementation
[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-14 As shown:
[0040] A duster with dual wiping heads includes a handle 1, a connecting seat 10 fixed to the end of the handle 1, a fixed seat 2 rotatably mounted on the connecting seat 10, and a first wiping head 21 fixedly or integrally formed on the fixed seat 2; a mounting cavity 20 is provided in the middle of the fixed seat 2, and the connector 3 of the second wiping head 31 is sleeved in the mounting cavity 20 and the connector 3 can rotate and move up and down by relying on the mounting cavity;
[0041] like Figure 1-3 As shown, rotate the second wiping head 31 above the first wiping head 21 and keep it in the stacked state; the duster is in the first wiping state; as Figure 4-5 As shown, rotate the second wiping head above the first wiping head, maintaining a distance of L between the two wiping heads. The duster is then in the second wiping state. Figure 6-7As shown, rotating the second wiping head to the side of the first wiping head, the first and second wiping heads are arranged side-by-side, and the duster is in the third wiping state. In this application, the first and second wiping heads are arranged parallel to each other. During adjustment, the first wiping head remains stationary, while the second wiping head 31 rotates around the fixed base 2 of the first wiping head 21 or moves up and down relative to the first wiping head. The attachment in this application does not specify a disposable wiping cloth. Disposable wiping cloths are common components on the market and can be purchased directly, or customized according to the shape of the first and second wiping heads. The disposable wiping cloth is preferably an electrostatic fiber cloth. Different wiping states adapt to different cleaning scenarios, giving users more choices.
[0042] A locking element is provided between the connector 3 and the mounting cavity 20. When the locking element is active, the duster remains in a first wiping state, a second wiping state, or a third wiping state. The locking element is a spring-loaded latch, and the mounting cavity has a limiting part 23 that engages with the spring-loaded latch. When the spring-loaded latch is held at different limiting parts, the duster remains in the corresponding wiping state. The spring-loaded latch can be of various types, such as type 1, as shown in the attached diagram. Figure 9-14 As shown, the spring clip is formed by combining the spring clip body 5 and the spring 53. The spring 53 provides a force to the engaging part 51 of the spring clip body, which engages with the limiting part 23. In the second method, the spring clip is inherently elastic, and an elastic element is integrally formed or fixed on the spring clip. The elastic element causes the engaging part of the spring clip to engage with the limiting part. The limiting part can be a hole as shown in the attached figure, or it can be a recess or a protruding edge, as long as it can keep the spring clip in the designated position.
[0043] The device includes a pusher 4 connected to a locking member. The pusher allows the locking member to disengage from the limiting part 23, and the second wiping head 31 can move relative to the first wiping head 21. The pusher 4 can drive the movement of the spring-loaded latch in at least one of the following ways: Method 1: The pusher has a first inclined surface 41, and the spring-loaded latch has a second inclined surface 52 that cooperates with the first inclined surface 41. Pressing the pusher 4 moves it into the central cavity of the connector, pulling the spring-loaded latch inward, thereby separating the latching part from the limiting part. Method 2: The pusher and the spring-loaded latch are connected by a transmission rod. Pressing the pusher moves it into the central cavity of the connector, and under the action of the transmission rod, the spring-loaded latch moves inward, thereby separating the latching part from the limiting part. Any of the above solutions are acceptable, as long as the pusher can drive the movement of the spring-loaded latch. In this application, the pusher is located above the connector, making it convenient for the user to press it.
[0044] The connector 3 is hollow in the middle, and an opening is provided above the hollow cavity. The spring buckle and the pusher are both located in the middle cavity 30 of the connector. The engaging part of the spring buckle protrudes from the connector and can be connected to the corresponding limiting part.
[0045] The mounting cavity of the fixed base is provided with a track 23. The connector 3 of the second wiping head is provided with a protrusion 32 that limits its movement within the track. The connector 32 of the second wiping head moves along the track 23. Preferably, the track 23 is provided with a longitudinal section 231 and a transverse section 232. Two longitudinal sections 231 are symmetrically arranged on both sides of the transverse section 232, and the transverse section 232 is located above the longitudinal sections 231. When the duster switches between the first wiping state and the third wiping state, the second duster needs to move upward, rotate, and move downward in sequence. When the duster is in the first wiping state or the third wiping state, the protrusion remains at the bottom of the longitudinal section; when the duster is in the second wiping state, the protrusion remains in the transverse section. In the first wiping state and the third wiping state, the only direction of movement of the second wiping head is away from the first wiping head. This unlocking direction is opposite to or misaligned with the usage direction of the duster. Therefore, the first wiping head and the second wiping head can maintain the specified wiping state, thereby making the structure more stable.
[0046] Includes a locking cover 22, which is fixed above the mounting cavity 20 of the fixing base, and the locking cover 22 prevents the connector 3 of the second wiping head from disengaging from the mounting cavity 20 of the fixing base.
[0047] The mounting cavity 20 has a notch 25 on the other side of the first wiping head. When the duster is in the third wiping state, the second wiping head is confined within the notch 25, and the first and second wiping heads remain on the same plane. During use, the disposable wiping cloths installed on the first and second wiping heads are symmetrically arranged, resulting in better wiping performance. Preferably, a protrusion 26 is provided in the middle of the notch, and the second wiping head has a notch that mates with the protrusion 26. When in the third wiping state, the protrusion and the notch engage, making the structure more stable. Preferably, the first and second wiping heads are provided with a first wiping head hook 211 and a second wiping head hook 311, which secure the disposable wiping cloth.
[0048] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
