Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a press-to-clean comb dustpan with a hovering function, which is used to automatically remove hair, lint and other debris tangled on the broom when sweeping the floor, and has the functions of one-button pressing, hovering and locking, and hands-free cleaning. Background Technology

[0002] Current household dustpans often have a row of fixed teeth along the entrance edge to scrape off tangled hair when the broom head is pressed against the teeth. However, the scraped hair quickly gets tangled back onto the teeth, requiring users to remove it by hand or sweep again, which is unhygienic and prone to secondary contamination. Some products have retractable teeth that use springs to achieve a "scraping and retracting" action, but this still requires continuous hand pressure or both hands, making operation cumbersome and unable to keep the teeth in the extended or retracted state, resulting in a poor user experience.

[0003] Therefore, there is an urgent need for a comb-like dustpan that can be pressed with one hand, automatically locks, and maintains its state when released, in order to completely solve the problem of hair removal. Summary of the Invention

[0004] The purpose of this utility model is to provide a press-to-clean comb dustpan with a hovering function. Through the cyclic action of "one-button press - step-lock - press again to unlock", the comb assembly can be stably hovered in the extended working position or retracted cleaning position. Users do not need to apply continuous force or touch the dirty parts, and can scrape off the broom hair and process it in one go.

[0005] The purpose of this utility model is achieved as follows: A press-type cleaning comb-tooth dustpan with a hovering function includes a dustpan body, a comb tooth assembly, and a transmission structure connecting the dustpan body and the comb tooth assembly. The dustpan body has a front garbage inlet and a handle. The comb tooth assembly can move back and forth relative to the dustpan body. It also includes a press-type hovering locking mechanism disposed on the dustpan body. This mechanism includes a pressing component, a stepping rotation locking component, a guide sleeve, and a return spring. The guide sleeve is fixed to the dustpan body. The pressing component, the stepping rotation locking component, and the return spring are coaxially placed inside the guide sleeve from top to bottom. The pressing component and the stepping rotation locking component are coaxially connected by a pin connector. The pin connector is fixed to the pressing component. The stepping rotation locking component is sleeved on the pin connector and can rotate around it. The pressing component directly drives the comb tooth assembly through the transmission structure. By driving the pressing component and the return spring, the stepping rotation locking component and the guide sleeve are relatively locked, thereby suspending the comb tooth assembly in the extended or retracted position.

[0006] In the aforementioned press-to-clean comb-tooth dustpan, the inner wall of the guide sleeve is evenly distributed with axial guide grooves, and a locking wave surface is formed between adjacent guide grooves; the lower end face of the pressing member is provided with a full circle of axial gears, and each tooth tip of the axial gears is provided with a first guide rib that slides with the guide groove; the upper end face of the stepping rotation locking member is provided with a second guide rib that slides with the guide groove, and the upper end of the second guide rib is provided with a half-tooth step; each first guide rib axially pushes against the half-tooth step in the corresponding guide groove, so that the half-tooth step is pushed out of the guide groove and abuts against the circumference of the locking wave surface; during the return spring rebound stage, the half-tooth step slides along the locking wave surface and automatically aligns with the next guide groove, and the second guide rib falls into the groove, completing one stepping rotation.

[0007] In the aforementioned press-to-clean comb tooth duster, the transmission structure is an inclined sliding assembly, including a driving inclined surface, a driven inclined surface, and an elastic energy storage component. The driving inclined surface is located on the front side of the pressing component, and the driven inclined surface is located on the rear end of the comb tooth assembly, with the two inclined surfaces sliding in contact. When the pressing component is pressed down, the two inclined surfaces slide relative to each other and push the comb tooth assembly forward, while the elastic energy storage component stores energy. When the pressing component rebounds and rises, the driving inclined surface disengages from the driven inclined surface, the elastic energy storage component releases its stored energy, and causes the comb tooth assembly to retract backward.

[0008] In the aforementioned press-to-clean comb duster, the driving inclined surface is integrally formed with the pressing component or fixed on its front side as an independent wedge, and the inclined surface is inclined downwards and forwards; the driven inclined surface is inclined upwards and backwards, and the two inclined surfaces have the same inclination angle, forming a line contact sliding pair.

[0009] In the aforementioned press-to-clean comb tooth dustpan, a guide groove structure extending in the front-to-back direction is provided between the dustpan body and the comb tooth assembly to guide the extension and retraction movement of the comb tooth assembly.

[0010] In the aforementioned press-to-clean comb tooth dustpan, the guide groove structure consists of an upper guide groove and a lower guide groove that slide together. The upper guide groove is located on the comb tooth assembly and opens downwards, while the lower guide groove is located on the dustpan body and opens upwards. The two grooves interlock to form an energy storage and receiving cavity in the front-to-back direction.

[0011] In the aforementioned press-to-clean comb tooth dustpan, the energy storage cavity is provided with the elastic energy storage component, which is used to release the stored energy and cause the comb tooth assembly to return to its original position when the driving inclined plane disengages.

[0012] In the aforementioned press-to-clean comb-tooth dustpan, the elastic energy storage component is a compression spring. A compression cavity is formed in front of the energy storage cavity, and the compression spring is placed in this cavity. When it extends, it is compressed, and when it disengages, it is released, thus achieving the push-out return to the original position.

[0013] The aforementioned press-to-clean comb-tooth dustpan also includes a quick-release cover plate, which is fastened to the upper surface of the dustpan body. A perforated interception door is provided on the quick-release cover plate or the dustpan body. The interception door is located on the extension and retraction path of the comb assembly, and each comb tooth of the comb assembly can slide through the hole. When the comb assembly retracts from the extended state, the interception door blocks the tangled material from retracting with the comb teeth and forcibly pushes the tangled material to the waste inlet.

[0014] In the aforementioned press-to-clean comb-tooth dustpan, the lower end of the guide sleeve is connected to the dustpan body by a detachable snap-fit ​​connection.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] 1. This utility model has a press-type hovering locking mechanism, which has the advantages of one-handed operation and hands-free hovering: pressing and releasing locks the device, and pressing again unlocks it, without the need for both hands; the comb assembly can stay stably in the extended or retracted position without the user having to apply continuous force.

[0017] 2. This utility model features a hands-free cleaning method: upon retraction, the comb teeth slide relative to the interception gate, pushing the tangled material to the waste inlet in one go, avoiding hand contact and dirt.

[0018] 3. This utility model features modular quick-release: the guide sleeve is snapped together with the hopper body, allowing for quick disassembly for spring replacement or repair. Attached Figure Description

[0027] The present invention will be further described below with reference to specific embodiments:

[0028] like Figure 1-8 As shown, this utility model discloses a press-to-clean comb-tooth dustpan with a hovering function. Through the interaction of components such as the pressing element, the stepping rotary locking element, the guide sleeve, and the return spring, the comb tooth assembly achieves a hovering function. During use, the user drives the pressing element downwards, causing the stepping rotary locking element to lock relative to the guide sleeve, while the comb tooth assembly extends forward. Driving the pressing element downwards again causes the comb tooth assembly to retract under the action of the elastic energy storage element. This design not only facilitates the collection and cleaning of waste but also improves the convenience and comfort of use.

[0029] A press-type cleaning comb-tooth dustpan with a hovering function includes a dustpan body 100, a comb-tooth assembly 200, and a transmission structure 300 connecting the dustpan body and the comb-tooth assembly. The dustpan body 100 has a front waste inlet and a handle. The comb-tooth assembly 200 can move back and forth relative to the dustpan body 100. The dustpan body 100 is characterized by further including a press-type hovering locking mechanism 400 disposed on the dustpan body 100. This mechanism includes a pressing component 1, a stepping rotation locking component 2, a guide sleeve 3, and a return spring 4. The guide sleeve 3 is fixed to the dustpan body 100. The pressing component 1, the stepping rotary locking component 2, and the return spring 4 are coaxially placed inside the guide sleeve 3 from top to bottom. The pressing component 1 and the stepping rotary locking component 2 are coaxially connected by a pin connector. The pin connector is fixed to the pressing component 1, and the stepping rotary locking component 2 is sleeved on the pin connector and can rotate around it. The pressing component 1 directly drives the comb assembly 200 through the transmission structure 300, and the stepping rotary locking component 2 and the guide sleeve 3 are relatively locked by the rebound of the pressing component 1 and the return spring 4, thereby suspending the comb assembly 200 in the extended or retracted position. In this technical solution, the pressing component and the stepping rotary locking component are connected by a pin connector. The pin connector synchronizes the axial relative position of the pressing component and the stepping rotary locking component and allows the stepping rotary locking component to rotate freely around the pin. The pressing-type hovering locking mechanism 1, through its unique design, enables the comb assembly 2 to hover stably in the extended or retracted position. This allows the user to flexibly adjust the working state of the comb assembly 2 as needed during cleaning, easily cope with different cleaning needs, and thus significantly improve the convenience and flexibility of cleaning.

[0030] Preferably, the inner wall of the guide sleeve 3 is evenly distributed with axial guide grooves 31, and a locking wave surface 32 is formed between adjacent guide grooves; the lower end face of the pressing member 1 is provided with a full circle of axial gear ring 11, and each tooth tip 111 of the axial gear ring 11 is provided with a first guide rib 12 that slides with the guide groove 31; the upper end face of the stepping rotation locking member 2 is provided with a second guide rib 21 that slides with the guide groove 31, and the upper end of the second guide rib 21 is provided with a half tooth step 21a; each first guide rib 12 axially pushes the half tooth step 21a in the corresponding guide groove 31, so that the half tooth step 21a is pushed out of the guide groove 31 and circumferentially abuts against the locking wave surface 32; during the return spring 4 rebound stage, the half tooth step 21a slides along the locking wave surface 32 and automatically aligns with the next guide groove 31, and the second guide rib 21 falls into the groove, completing one stepping rotation. This technical solution enables the gradual locking and releasing of the comb assembly 2. This design not only enhances the stability of the hovering, but also achieves precise step adjustment through the sliding of the wave surface, simplifying the operation process and ensuring that the comb assembly 2 can accurately hover after each movement, making the dynamic adjustment operation smoother and avoiding the phenomenon of jamming.

[0031] Preferably, the transmission structure 300 is a sloping sliding assembly, including a driving sloping surface 301, a driven sloping surface 302, and an elastic energy storage component 303. The driving sloping surface 301 is located on the front side of the pressing member 1, and the driven sloping surface 302 is located on the rear end of the comb assembly 200, with the two sloping surfaces sliding together. When the pressing member 1 is pressed down, the two sloping surfaces slide relative to each other and push the comb assembly 200 forward, while the elastic energy storage component 303 stores energy. When the pressing member 1 rebounds and rises, the driving sloping surface 301 disengages from the driven sloping surface 302, the elastic energy storage component 303 releases the stored energy, and causes the comb assembly 200 to retract backward. In this technical solution, the inclined sliding component in the transmission structure 300 cleverly transforms the vertical movement of the pressing component 11 into the translational movement of the comb component 2; the linear sliding between the inclined surfaces ensures the smoothness of the movement, while the elastic energy storage component 303 alternately stores and releases energy during the pressing and releasing process, which significantly improves the operating efficiency of the comb component 2 extending and retracting.

[0032] Preferably, the driving inclined surface 301 is integrally formed with the pressing member 1 or fixed as an independent wedge on its front side, and the inclined surface is inclined downwards and forwards; the driven inclined surface 302 is inclined upwards and backwards, and the two inclined surfaces have the same inclination angle, forming a line contact sliding pair. This structure effectively reduces friction between structures, and the inclined surface design with the same inclination angle ensures the accuracy and stability of the movement, thereby greatly improving the overall transmission efficiency.

[0033] Preferably, a guide groove structure 500 extending in the front-to-back direction is provided between the dustpan body 100 and the comb assembly 200 to guide the extension and retraction movements of the comb assembly 200. This guide groove structure 500 provides precise guidance for the extension and retraction movements of the comb assembly 200, ensuring smooth movement and accurate path, thereby improving the accuracy and efficiency of cleaning.

[0034] Preferably, the guide groove structure 500 consists of an upper guide groove 501 and a lower guide groove 502 that slide together. The upper guide groove 501 is located on the comb assembly 200 and opens downwards, while the lower guide groove 502 is located on the hopper body 100 and opens upwards. The two grooves interlock to form an energy storage cavity in the front-to-back direction. In this technical solution, not only is an installation space provided for the elastic energy storage component 303, but the comb assembly 2 also plays a guiding and limiting role during its movement, ensuring the smoothness of the movement.

[0035] Preferably, the energy storage cavity is provided with the elastic energy storage element 303, which is used to release the stored energy and cause the comb assembly 200 to return to its original position when the driving inclined surface 301 disengages. This structure ensures that the comb assembly 2 can quickly and accurately return to its initial position, preparing for the next extension.

[0036] Preferably, the elastic energy storage element 303 is a compression spring, with a compression cavity formed in front of the energy storage cavity. The compression spring is placed in this cavity, where it is compressed and stores energy when extended and releases energy when released, thus enabling the comb assembly 2 to be pushed out and returned to its original position. This design is simple and efficient, providing stable power for the reciprocating motion of the comb assembly 2.

[0037] Preferably, a quick-release cover 600 is also included. The quick-release cover 600 is fastened to the upper surface of the dustpan body 100. A perforated interception gate 700 is provided on the quick-release cover 600 or the dustpan body 100. The interception gate 700 is located on the extension path of the comb assembly 200, and each comb tooth of the comb assembly 200 slidably passes through the hole. When the comb assembly 200 retracts from its extended state, the interception gate 700 prevents tangled debris from retracting with the comb teeth and forcibly pushes the tangled debris to the waste inlet. In this technical solution, the combination of the quick-release cover 600 and the perforated interception gate 700 effectively prevents tangled debris from retracting with the comb teeth when the comb assembly 200 retracts, forcibly pushing it to the waste inlet. This greatly improves the efficiency of waste collection and prevents tangled debris from entangled in the comb teeth and affecting the cleaning effect.

[0038] Preferably, the lower end of the guide sleeve 3 is detachably snap-fitted to the hopper body 100. This mechanism facilitates the installation and removal of the guide sleeve 3, making it convenient for users to clean, maintain, or replace the guide sleeve 3, thereby extending the product's service life.

[0039] In this technical solution, the handle is connected to the pressing part. The first press: the pressing part 1 moves down, the first guide rib 12 pushes the half tooth step 21a away from the guide groove 31. After releasing, under the rebound force of the return spring 4, the half tooth step 21a abuts against the locking wave surface 32. During this process, the driving inclined surface 301 pushes the driven inclined surface 302, the comb tooth assembly 200 extends forward and compresses the compression spring 303. At this time, the comb tooth is in the "working position", and the user can repeatedly brush the broom head. The hair is blocked in front of the comb tooth. Second press: Drive the pressing part 1 downward again, and the half-tooth step 21a slides along the locking wave surface 32 and falls into the next guide groove 31; after releasing, under the action of the reset spring 4, the pressing part 1 moves upward to reset; at the same time, the driving inclined surface 301 disengages from the driven inclined surface 302, the compression spring 303 releases energy, and pushes the comb tooth assembly 200 to retract quickly. The comb teeth slide relative to the interception gate 700, and the tangled material is pushed into the garbage inlet in one go, completing the "self-cleaning".

[0040] 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.
