Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent cleaning equipment, especially pool cleaning technology, and more specifically, to a double-roller brush pool robot. Background Art
[0002] Under the background of the booming development of current technological innovation and high-end manufacturing, pool robots, as a professional cleaning device, are becoming increasingly important. Such robots are specifically designed to clean private or public pools, which can not only significantly save labor costs, but also have a more thorough and efficient cleaning effect compared with traditional manual cleaning methods.
[0003] In existing pool robots, a sewage suction port is usually provided at the front or bottom thereof, and a roller brush is provided at the front end corresponding to the sewage suction port. The function of the roller brush is to scrape the garbage at the bottom of the pool into the pool robot through the roller brush. In addition to the sedimented particulate garbage at the bottom of the pool, there are usually flaky garbage such as fruit peels, leaves, plastic sheets, etc., as well as long-strip garbage such as branches and thick particulate matter such as coarse gravel. Such flaky, long-strip or coarse particulate garbage is relatively heavy and will quickly sink to the bottom of the pool again when scraped by the roller brush; at the same time, due to the insufficient suction of the water pump of the pool robot, it cannot quickly suck it into the pool robot. Therefore, the collection effect of flaky, long-strip or coarse particulate garbage is very unsatisfactory.
[0004] Therefore, how to better collect the flaky, strip-shaped or coarse particulate garbage deposited at the bottom of the pool is a technical problem that the industry urgently needs to solve. Summary of the Invention
[0005] The present invention aims to overcome the above deficiencies in the prior art and provides a double-roller brush pool robot to solve the problems of insufficient suction of existing double-roller brush pool robots and difficult collection of garbage such as flaky objects like leaves, long-strip objects like branches, or coarse particulate matter like stones.
[0006] The technical solution adopted by the present invention is to provide a double-roller brush pool robot, including a body. In the present invention, the body is the housing of the pool robot. The body is provided with an inner cavity, and a traveling mechanism is provided at the lower part or side part of the body.
[0007] A garbage storage device, which is arranged in the inner cavity of the body. A collection port is provided at the lower part of the garbage storage device, and a filter screen is provided at the side part and / or top of the garbage storage device.
[0008] A drain port, which is provided at the top and / or side of the body, and the drain port is in communication with the inner cavity.
[0009] The water inlet is in communication with the collection port, and the water inlet is provided at the lower part, front part or side part of the body.
[0010] The rotary brush includes a rotary brush shaft and rotary brush pieces arranged on the outer periphery of the rotary brush shaft. The rotary brush is provided at the front part or lower part of the body, and the rotary brush is driven to rotate by a driving motor or by the traveling mechanism.
[0011] The secondary brush is provided at the water inlet. The main brush and the secondary brush are respectively arranged on two sides of the water inlet, and the rotation direction of the secondary brush is opposite to that of the rotary brush.
[0012] By adding the secondary brush, the secondary brush and the main brush cooperate with each other to collect the garbage.
[0013] As a further optimization of the above technical solution, the secondary brush includes a base body and a brush body. The brush body is rotatably arranged in the base body. The brush body includes a rotating shaft and a plurality of rows of scraping pieces arranged on the rotating shaft. Concave teeth are arranged in the base body, and the concave teeth correspond to the scraping pieces. When the brush body rotates, the scraping pieces move in the concave teeth.
[0014] As is well known, when the scraping pieces rotate, the base body must leave a gap for the scraping pieces to pass through. Therefore, the concave teeth are mainly provided to enable the secondary brush to rotate better when working during rotation.
[0015] As a further optimization of the above technical solution, at least part of the scraping pieces overlap with the rotary brush pieces.
[0016] The function of partial overlap is that when they overlap, the garbage can be lifted and collected, so that there is no need to worry about the problem that it is difficult to collect the garbage due to insufficient suction of the pool robot water pump.
[0017] As a further optimization of the above technical solution, one side surface of the base body has a working surface. The working surface is fan-shaped, and the working surface is one side surface of the water inlet. The concave teeth are arranged at the working surface.
[0018] The fan-shaped working surface forms a better water flow channel, making it easier for the garbage to enter the pool robot body for collection.
[0019] As a further optimization of the above technical solution, the central angle of the fan shape is 170°≤110°.
[0020] As a further optimization of the above technical solution, the fan-shaped working surface has an upper working surface and a lower working surface respectively. When the concave teeth are arranged at the working surface, there are upper concave teeth and lower concave teeth. When the scraping pieces rotate, two rows of the scraping pieces are simultaneously arranged at the upper concave teeth and the lower concave teeth of the upper working surface and the lower working surface.
[0021] Similarly, the upper concave teeth and the lower concave teeth facilitate the passage of the scraping blade during rotation.
[0022] As a further optimization of the above technical solution, a secondary brush gear is provided at one end of the base body, and a shaft gear is provided on the traveling mechanism, and the secondary brush gear meshes with the shaft gear.
[0023] Adding the secondary brush gear can drive the secondary brush to rotate.
[0024] As a further optimization of the above technical solution, the lower part of the base body is provided with a hollow; alternatively, the lower part of the base body is provided with a through hole; alternatively, the lower part of the base body is provided with a drain trough.
[0025] The function of the hollow, through hole or drain trough is that when the pool robot is lifted, the water and debris inside can be discharged smoothly.
[0026] As a further optimization of the above technical solution, the secondary brush is at least two sections, and at least one section is driven by the traveling mechanism to rotate.
[0027] As a further optimization of the above technical solution, the scraping blade is trapezoidal or wedge-shaped.
[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0029] A double-roller brush pool robot provided by the present invention, by adding a secondary brush structure, when collecting leaves, stones, and large-particle garbage, the use of the mutual forces between the roller brush and the secondary brush makes it easier to be lifted and stored, thereby increasing the cleaning effect.

Specific implementation manner
[0038] The attached drawings of the present invention are only for illustrative purposes and should not be construed as a limitation to the present invention. For better illustration of the following embodiments, some components in the attached drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted.
[0039] Embodiment 1
[0040] As Figures 1 - 7 shown, this embodiment provides a double-roller pool robot, including a body 100. The body 100 in this embodiment is the outer shell of the pool robot. The body 100 is provided with an inner cavity 101, and a traveling mechanism 102 is provided at the lower part or side of the body 100. The traveling mechanism 102 is a traveling wheel or a traveling track. Both the traveling wheel and the traveling track are driven by a driving motor to move forward, backward, turn, etc., and their traveling modes are the same as those of existing pool robots. In this embodiment, the transmission structure of the traveling mechanism 102 will not be described in detail. In this embodiment, the traveling mechanism 102 is specifically a traveling wheel.
[0041] Garbage collection device 200, the garbage collection device 200 is arranged in the inner cavity 101 of the body 100. A collection port is arranged at the lower part of the garbage collection device 200, and a filter screen is arranged at the side or / and top of the garbage collection device 200. The garbage collection device 200 described in this embodiment is also called "garbage bin", "garbage warehouse", etc. in existing pool robots. Its principle is that the water in the pool enters from the collection port and then flows out to the drain port 103 through the filter screen, while the garbage or coarse particles mixed in the water are blocked by the filter screen and stay in the garbage collection device 200, achieving the effect of garbage collection.
[0042] A drain opening 103 is provided at the top and / or side of the outer housing of the main body 100, and the drain opening 103 is in communication with the inner cavity 101. Since a garbage collection device 200 is provided at the inner cavity 101, it is also in communication with the garbage collection device 200.
[0043] An inlet 104 is in communication with the collection port, and the inlet 104 is provided at the lower part, front part or side part of the main body 100. In a specific implementation, the inlet 104 and the collection port may also overlap or share a common entrance.
[0044] A rotary brush, the rotary brush includes a rotary brush shaft 105 and rotary brush pieces 106 provided on the outer periphery of the rotary brush shaft 105, and is provided at the front or lower part in the traveling direction of the main body 100. The rotary brush is directly driven to rotate by a driving motor, or the motor drives the traveling mechanism 102 to rotate, and then the traveling mechanism 102 drives the rotary brush to rotate. In this embodiment, the driving motor first drives the traveling mechanism 102 to rotate, and then the traveling mechanism 102 drives the rotary brush to rotate. The rotary brush pieces 106 are used for collecting garbage, and can also scrape the bottom wall, side wall and water level line of the swimming pool, making it easier to collect garbage and cleaner.
[0045] A secondary brush 300 is provided at the inlet 104. The rotary brush and the secondary brush 300 are respectively arranged on the front and rear sides of the inlet 104, and the rotary brush and the secondary brush 300 are arranged in parallel; when working, the rotation direction of the secondary brush 300 is opposite to that of the rotary brush.
[0046] In one embodiment, the secondary brush 300 includes a base body 301 and a brush body 302. The base body 301 is fixedly connected to or integrally formed with the main body 100, such as Figure 3 or Figure 5 shown, the brush body 302 is rotatably arranged in the base body 301. The brush body 302 includes a rotating shaft 306 and a plurality of rows of scraping pieces 308 arranged on the rotating shaft 306. Concave teeth 303 are arranged in the base body 301, and the concave teeth 303 correspond to the scraping pieces 308. When the brush body 302 rotates, the scraping pieces 308 move in the concave teeth 303.
[0047] As is well known, when the secondary brush 300 rotates, a space must be reserved for the wiper blade 308 provided on the secondary brush 300 so that it can rotate. Otherwise, if the wiper blade 308 is blocked, it cannot rotate freely on the base 301. Therefore, the main function of the concave teeth 303 is to allow the wiper blade 308 to move well within the concave teeth 303 when the secondary brush 300 rotates. Therefore, the wiper blade 308 corresponds to the concave teeth 303, and the width of the concave teeth 303 must be greater than or equal to the width of the wiper blade 308. In this embodiment, it is preferred that the width of the concave teeth 303 is equal to the width of the wiper blade 308.
[0048] In one embodiment, the wiper blade 308 at least partially overlaps with the roller brush blade 106. When there is partial overlap, when the roller brush blade 106 rotates, it can drive the wiper blade 308 to move a certain distance, thereby driving the secondary brush 300 to rotate.
[0049] When the roller brush blade 106 overlaps with the wiper blade 308, it can also clamp coarse particle garbage, sheet garbage, or strip garbage to perform a lifting action, facilitating its adsorption and storage.
[0050] As Figure 7 shown, in one embodiment, one side of the base 301 has a working surface, the working surface is fan-shaped, and the working surface is one side of the water inlet 104, and the concave teeth 303 are provided at the working surface.
[0051] In one embodiment, the central angle of the fan shape is 170° ≤ 110°. Preferably, it is 160°, so that water and garbage can enter better.
[0052] In one embodiment, the fan-shaped working surface respectively has an upper working surface 304 and a lower working surface 305. When the concave teeth 303 are provided at the working surface, there are upper concave teeth and lower concave teeth. When the wiper blade 308 rotates, two rows of the wiper blades 308 are simultaneously placed at the upper concave teeth and the lower concave teeth of the upper working surface 304 and the lower working surface 305. When two rows of the wiper blades 308 are simultaneously placed at the upper concave teeth and the lower concave teeth of the upper working surface 304 and the lower working surface 305, at this time, the wiper blade 308 just blocks the position of the concave teeth 303 of the upper working surface 304 and the lower working surface 305, forming an integral plane, which is more conducive to the passage of water.
[0053] As Figure 4 shown, in one embodiment, one end of the rotating shaft 306 is provided with a secondary brush gear 307, and an axle gear 107 is provided on the traveling mechanism 102. The secondary brush gear 307 meshes with the axle gear 107. The traveling mechanism 102 of this embodiment is driven by a driving motor. Therefore, when the driving motor drives the traveling mechanism 102, the axle gear 107 provided on the driving mechanism drives the secondary brush gear 307 to rotate, thereby driving the secondary brush 300 to rotate.
[0054] At this time, when rotating, the scraping piece 308 on the secondary brush 300 may not contact the roller brush piece 106, or there may be a gap formed, and the gap can increase the water flow. The same effect of garbage collection can be achieved.
[0055] In one embodiment, the lower part of the base body 301 is provided with a hollow; alternatively, the lower part of the base body 301 is provided with a through hole; alternatively, the lower part of the base body 301 is provided with a water draining groove. The function of the hollow or the through hole or the water draining groove is mainly to enable the water, particulate matters, etc. inside to directly drain out from the hollow or the through hole or the water draining groove when the pool robot is lifted.
[0056] As Figure 5 shown, in one embodiment, the secondary brush 300 is at least two sections, and at least one section is driven to rotate by the traveling mechanism 102. Another section can rotate freely or be driven to rotate by partially overlapping with the roller brush piece 106. Both can achieve the technical effects described in this embodiment.
[0057] In this embodiment, the scraping piece 308 on the secondary brush 300 can also be set in a trapezoidal or wedge shape, so that not only the effect of garbage collection can be achieved, but also because the working surface is narrowed, the influence of the water flow is reduced.
[0058] In this embodiment, the scraping piece 308 on the secondary brush 300 is arranged according to the concave teeth 303, and the concave teeth 303 are arranged in a row on the base, so the scraping piece 308 also needs to be arranged row by row. In this embodiment, at least one row of scraping pieces 308 can also achieve the required effect, but for a single row of scraping pieces 308, it only works once when rotating one week, and the efficiency is greatly reduced. Therefore, 6 - 12 rows of scraping pieces 308 can be set. When there are more than 12 rows of scraping pieces 308, because the layout of the scraping pieces 308 is too dense, it is not easy to pick up stones or large pieces of leaves, branches, etc., and the effect is reduced. As Figure 6 shown, there are 12 rows of scraping pieces 308 in the figure of this embodiment.
[0059] Obviously, the above - mentioned embodiments of the present invention are only examples for clearly explaining the technical solutions of the present invention, and are not limitations on the specific implementation manners of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the claims of the present invention shall be included in the protection scope of the claims of the present invention.
