Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning equipment with efficient cleaning and drying functions. Background Technology

[0002] Carpet cleaning equipment typically consists of a roller brush system, a spray system, a suction system, and a drying system. During use, the roller brush generates friction through high-speed rotation, working in conjunction with cleaning fluid to break down stains. Simultaneously, the suction port collects wastewater in real time, achieving simultaneous "brushing-vacuuming." The drying system then dries the carpet after brushing and vacuuming. For example, Chinese utility model patent CN214856434U, entitled "A Brush-Spray-Extract High-Temperature High-Pressure Air-Drying Carpet Cleaning Machine," designs a brush-spray-extract high-temperature high-pressure air-drying carpet cleaning machine, including a main unit, a cleaning head assembly, and a drying assembly. It utilizes a high-pressure pump, a heater, and multiple fans to spray and extract stains with high-temperature, high-pressure water. Combined with a wide-angle water nozzle, a filament-coated brush disc, and a polishing metal suction nozzle, it performs deep cleaning and connects to a drying generator via a drying pipe interface for high-temperature air drying.

[0003] However, the existing technology still has the following drawbacks:

[0004] 1. The existing carpet cleaning equipment has its roller brush cleaning mechanism and drying mechanism directly connected to the front and rear of the machine body, respectively. The assembly with the machine body is not compact enough, and both occupy a lot of space, resulting in a large overall size, high transportation costs, and inconvenience in use.

[0005] 2. The existing drying mechanism's structural design cannot perform large-scale and efficient air drying of carpets in one go, resulting in low air drying efficiency.

[0006] 3. The existing roller brush cleaning mechanism's layout design between the water outlet mechanism, wastewater recycling mechanism, and roller brush head cannot achieve efficient cleaning and wastewater recycling. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a cleaning device with efficient cleaning and drying functions.

[0008] The purpose of this utility model is achieved by the following technical solution: a cleaning device with efficient cleaning and drying functions, including a body, a cleaning mechanism and a drying mechanism, wherein the body has a frame, and the frame is provided with a horizontal mounting part and a vertical mounting part at the front and rear ends of the device in the forward direction of the device, respectively.

[0009] The cleaning mechanism has a clean water tank, a wastewater tank, a brush plate, and several roller brush heads installed at the bottom of the brush plate for cleaning carpets. The brush plate is connected to the clean water tank and the wastewater tank and is located below the horizontal mounting part.

[0010] The air-drying mechanism has a mounting base and an air-drying scraper. The mounting base is adjustablely positioned below the vertical mounting part. The air-drying scraper is positioned below the mounting base and is at the same horizontal level as the roller brush head. When the several roller brush heads of the brush disc clean the carpet in the forward direction, the air-drying scraper is used to immediately follow and air-dry the carpet after it has been roller-brushed.

[0011] Furthermore, the vertical mounting part of the frame is provided with a vertical mounting frame, the upper end of the vertical mounting frame is connected to the vertical mounting part, and the lower end of the vertical mounting frame is provided with several connecting arms that open to both sides.

[0012] The mounting base is connected to the connecting arm, and the air-drying brush is arranged in a strip-like structure at the lower part of the mounting base. The brush length of the air-drying brush is equal to or greater than the diameter of the brush disc.

[0013] Furthermore, the drying brush is also configured with an arc-shaped structure, and the inner side of the arc of the drying brush faces the direction of carpet movement.

[0014] Furthermore, the drying mechanism also includes a dryer, which is mounted on a vertical mounting frame. The dryer duct connects the mounting base and the drying brush, so that the drying brush dries the carpet in the forward direction using the airflow provided by the dryer.

[0015] Furthermore, the lower part of the mounting base has a mounting cavity, and the mounting cavity is connected to the air dryer through a pipe;

[0016] The top of the air-drying brush is provided with a snap-fit ​​protrusion that is adapted to the mounting cavity. The snap-fit ​​protrusion is provided with a plurality of air holes that are arranged along the length of the air-drying brush and communicate with the mounting cavity, and a wind deflector arranged above the air holes.

[0017] Furthermore, the bottom of the air-drying brush is provided with several brush heads distributed around the opening of the air blowing hole.

[0018] Furthermore, the frame is configured as an L-shaped structure, and a fixed horizontal plate is provided on the vertical mounting part of the L-shaped frame. The upper end of the vertical mounting frame is provided with an adjustment plate with holes, and the adjustment plate is connected to the fixed horizontal plate, so that the vertical mounting frame can be adjusted and assembled on the vertical mounting part of the frame.

[0019] Furthermore, the brush plate has several wastewater tanks arranged in a circumferential array on its top. One end of each wastewater tank converges and connects to the center of the bottom of the brush plate. The converging end of each wastewater tank is connected to the wastewater tank, so that the wastewater tank can collect the wastewater generated during cleaning through the wastewater tanks when the wastewater tank is under negative pressure.

[0020] Furthermore, a brush head mounting groove is provided at the bottom of the brush plate corresponding to the position of the sewage tank. The brush head mounting groove is connected to the sewage tank, and a roller brush head can be detachably installed on each of the brush head mounting grooves.

[0021] Furthermore, the bottom circumferential array of the brush disk is provided with a plurality of nozzle mounting slots, and a nozzle is installed on each nozzle mounting slot. One end of the plurality of nozzles converges and connects to the bottom center of the brush disk, and the converged end of the plurality of nozzles is connected to the clean water tank pipe for pumping the cleaning fluid in the clean water tank to each nozzle.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] (1) In this embodiment, the cleaning mechanism is mounted below the horizontal mounting part at the front of the frame via its brush disc, while the drying mechanism is mounted below the vertical mounting part at the rear of the frame via its mounting base. This allows the two functional modules of cleaning and drying to be tightly integrated in the limited space of the frame, one in front and one behind, one above and one below, realizing the "overlapping assembly" and "embedded set" of the two functional modules in the longitudinal and / or transverse space of the machine body, rather than the traditional design of attaching two large mechanisms to the front and rear of the machine body respectively. This greatly reduces the length of the equipment in the cleaning direction, making the overall structure very compact and the size significantly smaller, reducing transportation and storage costs, and making it more flexible and convenient to use. In addition, based on the above-mentioned integrated assembly of the two functional modules of brush disc and drying mechanism in the frame, the drying brush after initial adjustment can be at the same height as the roller brush head, ensuring that the carpet area just cleaned by the roller brush head can be immediately dried by the drying brush head that follows, realizing the close connection between cleaning and drying, thus forming a "wash and dry" workflow and improving the cleaning efficiency of the equipment for carpets.

[0024] (2) In this embodiment, the drying mechanism is mounted on the frame in a "suspended" manner using an independent vertical mounting bracket. The structural design of the vertical mounting bracket and the connecting arms that open to both sides provides a robust and space-saving connection method, ensuring the stability of the drying mechanism while maintaining overall compactness. The length of the drying brush is equal to or greater than the diameter of the brush disc, ensuring that its drying range can completely cover the area cleaned by the roller brush. The equal-length design of the drying brush ensures that there are no dead corners in the drying process, allowing for large-area drying and avoiding any missed areas. In addition, the arc-shaped design of the brush improves the utilization rate and guidance of airflow, enabling the drying airflow to adhere more closely to and gather on the carpet surface, reducing airflow dissipation and further improving the cleaning efficiency of the equipment.

[0025] (3) The cleaning mechanism implemented in this application embeds the water nozzle into the nozzle mounting slot. Through the alternating arrangement of the nozzle mounting slot and the brush mounting slot, and the high-speed rotation of the brush plate during use, the water flow sprayed from the water nozzle directly acts on the area brushed by the roller brush head. This makes the water supply and the roller brush more coordinated, with high utilization and better cleaning effect. After the sewage is brushed up, since the brush mounting slot is connected to the sewage tank, and the sewage tank, roller brush head and water nozzle are arranged alternately, the sewage can be immediately sucked into the sewage tank by negative pressure, which greatly shortens the migration path of the sewage. With the suction of the vacuum pump, the effect of "sewage is generated and recycled" is achieved, which effectively prevents the sewage from being smeared again by the roller brush head or seeping into the deep layer of the carpet, causing secondary pollution. The sewage recycling efficiency is much higher than that of the traditional layout. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0041] like Figure 1-9 As shown, a cleaning device with efficient cleaning and drying functions is disclosed. This cleaning device is used for cleaning and drying carpets and other bedding. The carpet cleaning device mainly includes a body 10, a cleaning mechanism 20, and a drying mechanism 30. Among them, the body 10 is the basic support structure of the entire carpet cleaning device, and the body 10 has a frame 101 and a protective shell covering the frame 101.

[0042] The frame 101 is made of metal tubing bent into an L-shape, in the direction of equipment movement ( Figure 8 In the direction indicated by the middle arrow F (i.e., the cleaning direction), a horizontal mounting part 1011 is provided at the front end of the frame 101, and a vertical mounting part 1012 is provided at the rear end of the frame 101. This design of the mounting parts of the frame 101, one horizontal and one vertical, allows for a compact overall layout of the equipment when installing the cleaning mechanism 20 and the drying mechanism 30. In this embodiment, the horizontal mounting part 1011 and the vertical mounting part 1012 can be an integral structure directly formed on the frame 101, or they can be independent components connected later by welding, bolts, or other methods.

[0043] More specifically, the cleaning mechanism 20 is responsible for scrubbing the carpet. The cleaning mechanism 20 has a brush disc 201, which is horizontally and rotatably mounted below the horizontal mounting portion 1011 via a bracket or bearing. A motor is mounted on the bracket, and the motor's output shaft is connected to the brush disc 201 via a gear set, driving the brush disc to rotate at high speed below the horizontal mounting portion 1011. The brush disc 201 can be fully or partially stored below the horizontal mounting portion 1011 of the frame 101, thereby reducing the horizontal space occupied by the equipment. Several roller brush heads for cleaning the carpet are mounted at the bottom of the brush disc 201. Driven by the motor, these roller brush heads rotate at high speed along with the brush disc 201 during operation, and scrub and remove stains from the carpet fibers when clean water is applied.

[0044] The drying mechanism 30 is responsible for immediately drying the still-wet carpet after cleaning. The drying mechanism 30 has a mounting base 301 and a drying brush 302. The mounting base 301 is located below the vertical mounting section 1012. The drying brush 302 is detachably mounted on the lower part of the mounting base 301. When installing the drying mechanism 30, its vertical installation position can be precisely adjusted so that the bottom end of the drying brush 302 is at the same cleaning level as the bottom end of the roller brush head of the cleaning mechanism 20. This ensures that after the roller brush head in the cleaning direction washes the carpet, the drying brush 302 can quickly dry the carpet and recover wastewater.

[0045] Therefore, the cleaning mechanism 20 is mounted below the horizontal mounting portion 1011 at the front end of the frame 101 via its brush 201, while the drying mechanism 30 is mounted below the vertical mounting portion 1012 at the rear end of the frame 101 via its mounting base 301. This allows the two functional modules of cleaning and drying to be tightly integrated into the limited space of the frame 101, one in front and one behind, one above and one below. This achieves "overlapping assembly" and "embedded set" of the two functional modules in the longitudinal and / or lateral space of the body 10, rather than the traditional design of attaching two large mechanisms to the front and rear of the body 10 respectively. This greatly reduces the length of the equipment in the cleaning direction, making the overall structure very compact and the size significantly smaller, reducing transportation and storage costs, and making it more flexible and convenient to use. Furthermore, based on the integrated assembly of the brush plate 201 and the air-drying mechanism on the frame, one in front of the other and one above the other, the air-drying scraper 302 after initial adjustment can be at the same height as the roller brush head. This ensures that the carpet area just cleaned by the roller brush head can be immediately dried by the air-drying scraper 302, achieving a close connection between cleaning and drying, thus forming a "wash and dry immediately" workflow and improving the efficiency of the equipment in cleaning carpets.

[0046] like Figure 1-2As shown, this embodiment of the application also optimizes the installation structure of the drying mechanism 30 and the shape of the drying brush 302. More specifically, a vertical mounting bracket 40 is provided on the vertical mounting part 1012 of the frame 101. The upper end of the vertical mounting bracket 40 is connected to the vertical mounting part 1012 by bolts and / or locking pins. The lower end of the vertical mounting bracket 40 is provided with several connecting arms 402 that open to both sides (perpendicular to the cleaning direction). The number of connecting arms 402 can be two, three or more to provide optimal stability. The top of the mounting base 301 is provided with corresponding connecting parts, which are fixedly connected to these connecting arms 402 by hand-tightening bolts. Disassembly and replacement can be completed by hand-tightening.

[0047] The air-drying brush 302 is arranged in a long strip structure at the lower part of the mounting base 301, such as... Figure 9 As shown, the brush length L is designed to be equal to or greater than the diameter D of the brush disk 201; in this embodiment, it is preferred that the two are equal. Preferably, the drying brush 302 is also configured as an arc-shaped structure, and its inner arc faces the carpet cleaning direction (F direction).

[0048] Therefore, the drying mechanism 30 is mounted on the frame 101 via a separate vertical mounting bracket 40 using a "suspended" method. The structural design of the vertical mounting bracket 40 and the connecting arms 402 that open to both sides provides a robust and space-saving connection, ensuring the stability of the drying mechanism 30 while maintaining overall compactness. The length of the drying brush 302 is equal to or greater than the diameter of the brush disc, ensuring that its drying range completely covers the cleaning area of ​​the roller brush. The equal-length design of the drying brush 302 ensures thorough drying without dead corners, covering a wide area and preventing any areas from being missed. Furthermore, its arc-shaped structure design improves airflow utilization and guidance, allowing the drying airflow to adhere more closely and converge on the carpet surface, reducing airflow dispersion and further improving the cleaning efficiency of the equipment.

[0049] The drying mechanism 30 also includes a dryer 303 (such as a centrifugal fan or turbine fan), which is fixedly mounted on the vertical mounting frame 40 via a mounting bracket. The dryer 303 is directly mounted on the vertical mounting frame 40, placing it close to the working components, shortening the air duct, reducing pressure loss, and improving efficiency. The air outlet of the dryer 303 is connected to the internal cavity of the mounting base 301 via a flexible air duct, and the internal cavity of the mounting base 301 then directs the airflow to the drying scraper 302. The dryer 303 can also be installed in other locations inside the body 10, connected via a longer air duct. If necessary, the dryer 303 can have a speed-adjustable function to adapt to the drying needs of carpets with different humidity levels.

[0050] Therefore, the air dryer 303, acting as the air source, provides active and powerful drying capabilities. The airflow generated by the air dryer 303 is transported to the mounting base 301 through a pipe and finally blown out from the drying brush 302. Combined with the strip-shaped, equal-length, and curved design of the drying brush 302, it can perform large-scale, high-intensity, and high-efficiency drying treatment on freshly cleaned carpets in one go, solving the problem of inefficient drying using traditional suction-type air drying equipment.

[0051] like Figure 2-3 As shown in the embodiment, this application also optimizes the connection details between the drying brush 302 and the mounting base 301, as well as the air outlet structure. More specifically, the mounting base 301 has a mounting cavity 3011 at its lower part, and the top of the drying brush 302 is provided with a snap-fit ​​protrusion 3021 that matches the mounting cavity 3011. During installation, the snap-fit ​​protrusion 3021 of the drying brush 302 is snapped into the mounting cavity 3011 in the assembly direction and fixed with screws or clips, achieving quick disassembly and assembly, facilitating replacement and maintenance.

[0052] On the mounting protrusion 3021, a plurality of air holes 3022 are arranged along the length direction (i.e., the width direction of the device) of the drying brush 302. These air holes 3021 are connected to the mounting cavity of the mounting base 301, so that the airflow of the air dryer 303 passes through the mounting cavity and then blows out through the air holes 3022 to dry the carpet. The aperture and distribution density of the air holes 3022 in this embodiment can be adjusted according to actual usage needs. Above these air holes 3022, a baffle plate 3023 is also provided. The function of the baffle plate 3023 is to guide the airflow from the air duct of the air dryer, preventing the air from concentrating and blowing out from the central air hole, so that it is blown out more evenly from each air hole 3022 downwards. Several brush heads 3024 are provided at the bottom of the air-drying brush 302. The brush heads 3024 can be disassembled and replaced. These brush heads 3024 are preferably made of soft rubber or silicone material, and they are distributed around the opening of the air blowing hole 3022.

[0053] Therefore, the airflow path provided by the air dryer 303 in this embodiment is: air dryer 303 → air duct → inner cavity of mounting base 301 → bypassing the baffle plate 3023 → from the air outlet 3022 → acting on the carpet. The baffle plate 3023 optimizes the airflow distribution, ensuring uniform airflow along the entire length. The brush head 3024 at the bottom of the air drying brush 302 can physically remove a large amount of moisture from the carpet surface and comb the carpet pile before air drying. Through the combination design of "scraping water first and then blowing air", the drying load is reduced. In addition, the brush head 3024 can also smooth the carpet after drying, comb the carpet pile, and maintain the carpet's appearance, thereby improving the efficiency and effect of air drying. Furthermore, when working, it is close to the carpet, forming a relatively closed space to prevent airflow from escaping and to concentrate the airflow, forcing the airflow to penetrate the carpet fibers, which greatly improves the efficiency and effect of air drying.

[0054] This application provides a further description of the specific structure of the rack 101, such as... Figure 2-5 As shown, the frame 101 is formed into an L-shaped structure by bending a single metal tube. The horizontal portion forms a horizontal mounting section 1011, and the vertical portion forms a vertical mounting section 1012. Furthermore, one end of the horizontal mounting section 1011 is closed, while one end of the vertical mounting section 1012 consists of two separate metal tube ends used to mount a handrail 1014, facilitating user movement by holding the handrail 1014. Alternatively, the frame 101 can also be formed into an L-shaped structure using sheet metal or other components.

[0055] A fixed horizontal plate 1013 is provided on the vertical mounting section 1012 of the L-shaped frame. This fixed horizontal plate 1013 can be used as part of the frame to reinforce the structure of the frame 101 and to install the vertical mounting bracket 40. More specifically, the upper end of the vertical mounting bracket 40 is provided with an adjusting plate 401 with circular adjustment holes. By passing bolts through the circular holes at different positions on the adjusting plate 401 and then locking them to the fixed horizontal plate 1013, the vertical mounting bracket can be adjusted in height and assembled on the vertical mounting section of the frame, realizing the height adjustment of the vertical mounting bracket 40 (together with the entire drying mechanism 30) relative to the frame 101.

[0056] Therefore, the L-shaped frame 101 for bending metal tubes is simple, sturdy, and lightweight. Its height-adjustable design allows it to better handle different types of carpets, enabling users to adjust the pressure of the drying brush 302 on the carpet according to its thickness or wear condition, thus avoiding carpet abrasion, and also adapting to the roller brush head.

[0057] like Figure 4-6As shown in Figures 9 and 1, this embodiment of the application further optimizes the wastewater recycling, clean water spraying, and roller brush head layout of the cleaning mechanism 20. More specifically, the cleaning mechanism 20 also has a wastewater tank 202 and a vacuum pump 203 or negative pressure pump connected to the wastewater tank 202, which can create a negative pressure environment inside the tank. Several radially arranged wastewater troughs 2015 are arranged in a circumferential array on the top of the brush plate 201. One end (outer end) of these wastewater troughs 2015 extends towards the edge of the brush plate 201 to collect wastewater; the other end (inner end) converges and connects to the top center of the brush plate 201 to form a water collection chamber. The sewage tank 202 is connected to the water collection chamber via the vacuum pump 203 and the sewage pipe 205. Therefore, when the vacuum pump 203 is working, a negative pressure vacuum environment is formed in the sewage tank 202, the sewage pipe 205 and the water collection chamber. The strong suction will quickly draw the sewage collected in the sewage tank 2015 into the sewage tank 202 along the sewage pipe 205.

[0058] The bottom circumferential surface of the brush plate 201 has several brush head mounting slots 2014, which are arranged and connected one-to-one with the aforementioned wastewater tanks 2015. Each brush head mounting slot 2014 is detachably mounted with a roller brush head via clips or bolts. Users can choose to install a flat roller brush head 2011 (for general cleaning) or a curved roller brush head 2012 (for deep cleaning or special carpets). Therefore, through the corresponding arrangement of the roller brush heads and the wastewater tanks 2015, and the connection between the brush head mounting slots 2014 and the wastewater tanks 2015, the roller brush head can simultaneously and promptly collect wastewater generated at the brush position during cleaning, thereby improving wastewater collection efficiency.

[0059] The roller brush head can be designed with a quick-release structure for easy user replacement, and the replaceable roller brush head design increases the applicable scenarios of the equipment. The number of sewage tanks 2015 and clean water nozzles 2013 in this embodiment can be increased or decreased according to the size of the brush disc 201.

[0060] Meanwhile, the cleaning mechanism 20 also includes a clean water tank 206 and a clean water pump (not shown) connected to the tank. At the bottom of the brush plate 201, a plurality of nozzle mounting slots 2016 are arranged in a circumferential array, alternating with the aforementioned brush head mounting slots 2014 at the bottom of the brush plate 201. Each nozzle mounting slot 2016 corresponds to a clean water nozzle 2013. The alternating arrangement of the nozzle mounting slots 2016 and brush head mounting slots 2014 further alternates the clean water nozzles 2013 with the roller brush heads, thus coordinating the clean water supply and the roller brushes, further improving the cleaning effect and efficiency of the equipment.

[0061] The pipes of several water spray nozzles 2013 also converge and connect to the center of the bottom of the brush plate 201. The converging end is connected to the water pipe 204 from the water pump. Then, the water or detergent mixture in the water tank is pumped along the water pipe 204 to each water spray nozzle 2013 and sprayed on the carpet.

[0062] Therefore, by embedding the clean water nozzle 2013 into the nozzle mounting groove 2016 at the bottom of the brush plate 201, and through the alternating arrangement of the nozzle mounting groove and the brush head mounting groove, as well as the high-speed rotation of the brush plate during use, the water flow sprayed by the clean water nozzle 2013 directly acts on the area cleaned by the roller brush head. This makes the clean water supply and the roller brush more coordinated, with high utilization and better cleaning effect. After the sewage is brushed up, because the brush head mounting groove is connected to the sewage tank 2015, and the sewage tank, roller brush head and clean water nozzle are arranged alternately, the sewage can be immediately sucked into the sewage tank 2015 by negative pressure, which greatly shortens the migration path of the sewage. Combined with the powerful suction of the vacuum pump 203, the effect of "sewage is generated and recycled" is achieved, effectively preventing secondary pollution caused by sewage being smeared again by the roller brush head or seeping into the deep layers of the carpet. The sewage recycling efficiency is much higher than that of the traditional layout.

[0063] The working process of the carpet cleaning equipment provided in this embodiment is as follows:

[0064] 1. Preparation: The user fills the clean water tank with clean water or detergent mixture, ensuring that the wastewater tank 202 is empty; install the appropriate roller brush head on the brush plate 201 as needed, and connect the power supply.

[0065] 2. Start cleaning: The user pushes the equipment forward (cleaning direction F), the water pump starts, pumps clean water from the water tank, and sprays it precisely onto the carpet through the clean water nozzle 2013 at the bottom of the brush plate 201.

[0066] 3. Carpet cleaning: The motor drives the brush disc 201 to rotate at high speed, and the roller brush head cleans the wet carpet to remove dirt.

[0067] 4. Wastewater recycling: Vacuum pump 203 starts simultaneously, creating a strong negative pressure in wastewater tank 202, wastewater pipe 205 and wastewater trough 2015. The wastewater mixture generated by scrubbing is instantly sucked into the nearest wastewater trough 2015, and then flows along the trough to the central water collection chamber, and is finally sucked into wastewater tank 202 for storage, achieving rapid and efficient wastewater recycling.

[0068] 5. Scraping and air drying: The brush head 3024 at the bottom of the air drying brush 302 first scrapes away a large amount of excess water from the carpet surface; at the same time, the air dryer 303 is activated, and the strong airflow generated blows downward through the air duct from the air outlet 3022 of the air drying brush 302. The airflow, along with several brush heads 3024, acts on the cleaned wet carpet, quickly drying and evaporating the remaining moisture, achieving efficient air drying.

[0069] 6. After the equipment passes through, the carpet completes the entire process of cleaning, wastewater recycling, and air drying simultaneously, achieving the effect of washing and drying immediately.

[0070] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
