Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, specifically to a cleaning brush and a washing sink. Background Technology

[0002] Existing kitchen sinks have a relatively simple function, generally only used to hold a large amount of water for washing dishes. After use, dirt easily remains on the inner wall of the sink, and if it is not cleaned for a long time, it will produce an odor. It is not convenient to clean it by spraying water from the faucet.

[0003] To this end, Chinese patent application number CN202410217671.7, entitled "A Household Intelligent Dishwashing Device", adds an electric cleaning brush to the faucet to achieve the function of cleaning tableware, sink body and other items.

[0004] However, existing cleaning brushes have several drawbacks. First, the shape of the brush head is fixed and suitable for cleaning flat surfaces, but it is not good for cleaning curved surfaces. Second, after cleaning, the brush head needs to be manually cleaned, which is troublesome and results in a poor user experience. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a cleaning brush that is convenient for cleaning curved surfaces, in light of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning water tank using the above-mentioned cleaning brush.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning water tank that can realize the self-cleaning of the cleaning brush head.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: a cleaning brush, comprising a main body, a brush head rotatably mounted on the main body, and a driving mechanism for driving the brush head to rotate, characterized in that: the brush head includes...

[0009] An inner brush disk is rotatably connected to the main body, and the power output end of the drive mechanism is connected to the inner brush disk drive.

[0010] Multiple outer brush disks are arranged circumferentially around the outer periphery of the inner brush disk, and each outer brush disk is hinged to the inner brush disk; and

[0011] An elastic component acts between each of the outer brush disks and the main body, so that each of the outer brush disks always tends to flip away from the main body.

[0012] To simplify the structure, the inner brush disk is rotatably connected to the front of the main body via a rotating shaft;

[0013] The elastic component includes:

[0014] The connecting rod seat is slidably fitted onto the outer circumference of the rotating shaft;

[0015] Multiple connecting rods corresponding to the outer brush disks, each connecting rod having a first end hinged to a connecting rod seat and a second end hinged to a corresponding outer brush disk; and

[0016] An elastic element acts between the connecting rod seat and the main body to ensure that the connecting rod seat always has a tendency to move forward.

[0017] In this way, a single elastic element can ensure that each outer brush plate always tends to flip away from the main body.

[0018] To facilitate the installation of the elastic element, the elastic element is a compression spring, which is sleeved on the outer circumference of the rotating shaft, and its two ends respectively abut against the opposite surfaces of the connecting rod seat and the main body.

[0019] To enable the inner and outer brush discs to work together during cleaning, the front of the inner brush disc has multiple inner brush strips arranged circumferentially, and the front of the outer brush disc has outer brush strips corresponding to the inner brush strips. The inner end of the outer brush strip connects with the outer end of the corresponding inner brush strip, and together they form a complete combined brush strip.

[0020] To prevent water from splashing out when the brush head rotates, each of the combined brush strips extends in a spiral shape from the center of the brush head outwards along its rotation direction.

[0021] To facilitate cleaning the elongated inner wall of the cup, the outer ends of each of the outer brush strips extend outward from the outer peripheral wall of the outer brush disc.

[0022] To facilitate the cleaning of the outer curved surface by the brush head, both the inner and outer brush strips are flexible components, and the height of the outer brush strip is greater than that of the inner brush strip.

[0023] When no external force is applied, the front surface of the outer brush disk is flush with the front surface of the inner brush disk.

[0024] In order to achieve the hinge connection between the outer brush disk and the inner brush disk, the periphery of the inner brush disk has a plurality of mounting grooves corresponding to the outer brush disk. The mounting groove has a pin, and the inner side of each outer brush disk is provided with a rotating lug, which can be rotatably mounted on the corresponding pin.

[0025] In order to limit the extreme position of the external brush plate flipping away from the main body, the rotating lug abuts against the front side wall inside the corresponding mounting groove when no external force is applied.

[0026] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a cleaning water tank, including a tank body, characterized in that: it also includes the above-mentioned cleaning brush.

[0027] To further address the third technical problem mentioned above, a storage box for accommodating a cleaning brush is installed on the trough. The bottom of the storage box has a cleaning chamber, and the bottom of the storage box has a drain outlet connected to the cleaning chamber. When the cleaning brush is placed in the storage box, the brush head is housed in the cleaning chamber.

[0028] To prevent the storage box from affecting the normal function of the tank and to ensure aesthetics, the top edge of the tank has an outwardly extending flange with an installation opening for mounting the storage box.

[0029] To facilitate the placement and removal of the cleaning brush, the top of the storage box has an opening, and a lid is provided over the opening.

[0030] To improve aesthetics, the top surface of the lid is flush with the top surface of the flange.

[0031] To facilitate cleaning of the inner and outer surfaces, the main body includes a housing and a handle hinged to the rear of the housing, the brush head is rotatably connected to the front of the housing, and the drive mechanism is located inside the housing.

[0032] To avoid the cleaning brush taking up too much space when stored, the angle between the handle and the housing is 90° when the cleaning brush is placed in the storage box.

[0033] In order to facilitate the spraying of cleaning medium onto the surface to be cleaned by the brush head without affecting the rotation of the brush head, the brush head is rotatably connected to the front side of the housing via a rotating shaft. The shaft has a spray hole that runs through it axially. A water gun is fixed inside the housing, and the outlet end of the water gun is inserted into the spray hole.

[0034] In order to supply cleaning medium to the cleaning brush without increasing the weight of the cleaning brush, a cleaning medium supply device for supplying cleaning medium to the water gun is installed on the tank.

[0035] To provide both cleaning agent and hot / cold water, the cleaning medium supply device includes:

[0036] Cleaning agent bottle;

[0037] The integrated water circuit board has a detergent inlet, a cold water inlet, a hot water inlet, a detergent outlet, and both hot and cold water outlets.

[0038] The detergent inlet pipe has its inlet end connected to the outlet end of the detergent bottle and its outlet end connected to the detergent inlet end of the integrated water circuit board.

[0039] A cold water inlet pipe, the outlet of which is connected to the cold water inlet of the integrated water circuit board;

[0040] A hot water inlet pipe, the outlet of which is connected to the hot water inlet of the integrated water circuit board;

[0041] A detergent dispensing pipe, the inlet end of which is connected to the detergent dispensing end of the integrated water circuit board, and the outlet end of which is in fluid communication with the first outlet end of the water gun; and

[0042] The hot and cold water pipes have their inlet ends connected to the hot and cold water outlets of the integrated water circuit board, and their outlet ends are in fluid communication with the second outlet end of the water gun.

[0043] In order to achieve fluid communication between the detergent dispensing pipe and the hot and cold water pipes and the water gun, the storage box has a first threading port, the tail and head of the handle have threading tubes and second threading holes respectively, and the rear of the housing has a third threading hole.

[0044] The cleaning agent outlet tube is a flexible tube, whose outlet end passes through the first threading port and the threading tube in sequence and extends into the handle, then passes through the second threading hole and the third threading hole in sequence and extends into the housing and connects to the first inlet end of the water gun.

[0045] The hot and cold water pipes are flexible hoses, with their outlet ends passing through the first threading port and the threading tube in sequence to enter the handle, and then passing through the second threading hole and the third threading hole in sequence to enter the housing and connect to the second inlet end of the water gun.

[0046] To protect the detergent outlet pipe and hot and cold water pipes and simplify the wiring, the integrated water circuit board has a connecting pipe located on the outer periphery of its detergent outlet end and hot and cold water outlet end. A protective pipe is connected between the connecting pipe and the wiring pipe. The protective pipe is a flexible hose and is installed at the first wiring port and sealed to it. Both the detergent outlet pipe and the hot and cold water pipe are installed inside the protective pipe.

[0047] To avoid setting up an additional water supply line for the faucet, a faucet is installed on the tank, and the integrated water circuit board also has a cold water outlet and a hot water outlet.

[0048] The cleaning medium supply device also includes

[0049] A cold water outlet pipe, its inlet end connected to the cold water outlet end of the integrated water circuit board, and its outlet end connected to the water inlet end of the faucet; and

[0050] The hot water outlet pipe has its inlet end connected to the hot water outlet end of the integrated water circuit board, and its outlet end connected to the inlet end of the faucet.

[0051] In order to drive the brush head without affecting the internal piping connections of the housing, the drive mechanism includes:

[0052] The first gear is coaxially connected to the outer circumference of the rotating shaft;

[0053] The second gear meshes with the first gear; and

[0054] A driving component is used to drive the second gear to rotate.

[0055] Compared with the prior art, the advantages of the present invention are as follows:

[0056] (1) The brush head is composed of an inner brush disk connected to the main body by rotation, multiple outer brush disks arranged circumferentially around the outer periphery of the inner brush disk and hinged to the inner brush disk, and an elastic component acting between each outer brush disk and the main body. When cleaning the curved surface, the outer brush disk flips under the action of the surface to be cleaned, so that it can freely fit according to the state of the curved surface, making it convenient to clean various types of curved surfaces.

[0057] (2) By installing a storage box for accommodating the cleaning brush on the tank, and setting a cleaning chamber at the bottom of the storage box, and setting a drain outlet at the bottom of the storage box that communicates with the cleaning chamber, the brush head can be self-cleaned when the cleaning brush is placed in the storage box.

This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.

[0067] like Figures 1 to 6 The image shows a preferred embodiment of the cleaning tank of the present invention. The cleaning tank includes a tank body 1, a cleaning brush 2, and a cleaning medium supply device 3.

[0068] The tank 1 has an outwardly extending flange 11 at its top edge, with an installation port 111 on the flange 11. A storage box 112 with an open top is installed at the installation port 111. The bottom of the storage box 112 has a cleaning chamber 1121, and the bottom of the storage box 112 has a drain port 1122 that communicates with the cleaning chamber 1121. A first wire threading port 1123 is located on the side of the storage box 112 away from the drain port 1122. A cover 113 is installed over the open top of the storage box 112, and the top surface of the cover 113 is flush with the top surface of the flange 11. In addition, a faucet 12 is installed at the rear of the flange 11, to the left of the installation port 111.

[0069] The cleaning brush 2 can be removably housed in the storage box 112, and includes a main body 21, a brush head 22, and a drive mechanism 23.

[0070] The main body 21 includes a housing 211 and a handle 212 hinged to the rear of the housing 211; the tail and head of the handle 212 have a wire tube 2121 and a second wire hole 2122 respectively; the rear of the housing 211 has a third wire hole 2111, and a water gun 2112 is fixed inside the housing 211.

[0071] The brush head 22 includes an inner brush disc 221, an outer brush disc 222, and an elastic component 223;

[0072] Specifically, the inner brush disc 221 has a rotating shaft 2212 extending in the front-rear direction in the middle. The rotating shaft 2212 is rotatably connected to the front side of the housing 211, and a spray hole 2213 is axially opened inside the rotating shaft 2212. The outlet end of the water gun 2112 is inserted into the spray hole 2213. The periphery of the inner brush disc 221 has a plurality of mounting grooves 2214 corresponding to the outer brush disc 222 described below. A pin 2215 is provided in the mounting groove 2214. The front of the inner brush disc 221 has a plurality of inner brush strips 2211 arranged circumferentially and corresponding to the outer brush disc 222 described below.

[0073] There are multiple outer brush discs 222, which are arranged circumferentially around the outer periphery of the inner brush disc 221. Each outer brush disc 222 has a rotating lug 2222 protruding from its inner side. The rotating lug 2222 is rotatably mounted on a corresponding pin 2215, thereby achieving the hinge connection between the outer brush disc 222 and the inner brush disc 221. The front of the outer brush disc 222 has an outer brush strip 2221 corresponding to the inner brush strip 2211. The outer end of each outer brush strip 2221 extends outward from the outer peripheral wall of the outer brush disc 222, thereby facilitating the cleaning of the slender inner wall of a cup.

[0074] In addition, both the inner brush strip 2211 and the outer brush strip 2221 are flexible parts, and the height of the outer brush strip 2221 is greater than the height of the inner brush strip 2211. The inner end of each outer brush strip 2221 is connected to the outer end of the corresponding inner brush strip 2211, and together they form a complete combined brush strip 220. The combined brush strip 220 extends spirally from the center of the brush head 22 outward along its rotation direction. In this way, when the brush head 22 rotates, it will generate an inward force to push the water towards the center, thereby avoiding the problem of splashing water.

[0075] The elastic component 223 includes a connecting rod seat 2231, a connecting rod 2232, and an elastic element 2233;

[0076] The connecting rod seat 2231 can be slidably fitted onto the outer circumference of the rotating shaft 2212;

[0077] There are multiple connecting rods 2232, corresponding to the aforementioned outer brush discs 222. The first end of each connecting rod 2232 is hinged to the connecting rod seat 2231, and the second end of each connecting rod 2232 is hinged to the back of the corresponding outer brush disc 222; and

[0078] The elastic element 2233 is a compression spring, which is sleeved on the outer periphery of the rotating shaft 2212 and its two ends respectively abut against the opposing surfaces of the connecting rod seat 2231 and the housing 211, so that the connecting rod seat 2231 always has a tendency to move forward, thereby making each outer brush disk 222 always have a tendency to flip away from the housing 211.

[0079] In the absence of external forces, such as Figure 3 and Figure 4 As shown, the rotating lug 2222 abuts against the front side wall inside the corresponding mounting groove 2214, and the front of the outer brush disk 222 is flush with the front of the inner brush disk 221.

[0080] The drive mechanism 23 is located inside the housing 211 and includes a first gear 231, a second gear 232, and a drive member 233. Specifically, the first gear 231 is coaxially connected to the outer periphery of the rotating shaft 2212; the second gear 232 meshes with the first gear 231; the drive member 233 is a motor, and its power output end is coaxially connected to the second gear 232 to drive the second gear 232 to rotate around its own axis. When the drive member 233 is started, the second gear 232 is driven to rotate. Since the first gear 231 meshes with the second gear 232, the first gear 231 rotates accordingly and drives the entire brush head 22 to rotate through the rotating shaft 2212.

[0081] For the cleaning brush 2, the handle 212 and the housing 211 can be in a vertical state with an angle of 90° or in a straight state with an angle of 180°. The 90° vertical state can be used for cleaning the outer surface, and the 180° straight state can be used for cleaning the inner surface. When the cleaning brush 2 is placed in the storage box 112, the brush head 22 is located in the cleaning chamber 1121 and is arranged downwards, and the angle between the handle 212 and the housing 211 is 90°.

[0082] The cleaning medium supply device 3 is installed on the rear side of the tank 1 and arranged near the storage box 112, for supplying cleaning medium to the water gun 2112 of the cleaning brush 2. In this embodiment, the cleaning medium supply device 3 includes a cleaning agent bottle 31, an integrated water circuit board 32, a cleaning agent inlet pipe 33, a cold water inlet pipe 34, a hot water inlet pipe 35, a cleaning agent outlet pipe 36, a cold and hot water pipe 37, a cold water outlet pipe 38, and a hot water outlet pipe 39.

[0083] Specifically, the cleaning agent bottle 31 is installed at the rear of the flange 11, on the left side of the mounting port 111;

[0084] The integrated water circuit board 32 is installed on the rear side wall of the tank 1 and has a detergent inlet, a cold water inlet, a hot water inlet, a detergent outlet, a cold and hot water outlet, a cold water outlet, and a hot water outlet. The integrated water circuit board 32 has a connecting pipe 321 located on the outer periphery of its detergent outlet and cold and hot water outlet. A protective pipe 322 is connected between the connecting pipe 321 and the above-mentioned wiring pipe 2121. The protective pipe 322 is a flexible hose and is installed at the first wiring port 1123 and is sealed to it.

[0085] The inlet end of the cleaning agent inlet pipe 33 is connected to the outlet end of the cleaning agent bottle 31, and the outlet end of the cleaning agent inlet pipe 33 is connected to the cleaning agent inlet end of the integrated water circuit board 32.

[0086] The outlet end of the cold water inlet pipe 34 is connected to the cold water inlet end of the integrated water circuit board 32;

[0087] The outlet end of the hot water inlet pipe 35 is connected to the hot water inlet end of the integrated water circuit board 32;

[0088] The cleaning agent outlet pipe 36 is a flexible tube and is installed inside the aforementioned protective tube 322. The inlet end of the cleaning agent outlet pipe 36 is connected to the cleaning agent outlet end of the integrated water circuit board 32. The outlet end of the cleaning agent outlet pipe 36 passes through the first wire hole 1123 and the wire tube 2121 in sequence and extends into the handle 212. Then, it passes through the second wire hole 2122 and the third wire hole 2111 in sequence and extends into the housing 211 and connects to the first inlet end of the water gun 2112.

[0089] The hot and cold water pipes 37 are flexible hoses and are installed inside the aforementioned protective pipe 322. The inlet end of the hot and cold water pipes 37 is connected to the hot and cold water outlet ends of the integrated water circuit board 32. The outlet end of the hot and cold water pipes 37 passes through the first wiring port 1123 and the wiring pipe 2121 in sequence and extends into the handle 212. Then, it passes through the second wiring hole 2122 and the third wiring hole 2111 in sequence and extends into the housing 211, and is connected to the second inlet end of the water gun 2112.

[0090] The inlet end of the cold water outlet pipe 38 is connected to the cold water outlet end of the integrated water circuit board 32, and the outlet end of the cold water outlet pipe 38 is connected to the inlet end of the faucet 12.

[0091] The inlet end of the hot water outlet pipe 39 is connected to the hot water outlet end of the integrated water circuit board 32, and the outlet end of the hot water outlet pipe 39 is connected to the inlet end of the faucet 12.

[0092] In addition, hot and cold water are delivered by the water pressure of the tap water pipe, while the detergent is delivered by an electromagnetic pump. In this embodiment, the electromagnetic pump can be set at the detergent inlet pipe 33 or other suitable location. This is a conventional structure and is not shown in the figure.

[0093] The working principle of this embodiment is as follows:

[0094] (1) When cleaning, first open the box cover 113, then hold the handle 212 to take the entire cleaning brush 2 out of the storage box 112. Next, adjust the angle between the handle 212 and the housing 211 as needed, and finally start the cleaning brush 2. The drive mechanism 23 drives the brush head 22 to rotate.

[0095] When the surface is dirty and requires cleaning agent, the cleaning agent in the cleaning agent bottle 31 enters the integrated water circuit board 32 through the cleaning agent inlet pipe 33, and then is delivered to the spray nozzle 2213 of the brush head 22 through the cleaning agent outlet pipe 36 and the water gun 2112 to be sprayed out and applied to the surface to be cleaned.

[0096] When it is necessary to clean the dirt with water, cold or hot water enters the integrated water circuit board 32 through the cold water inlet pipe 34 or the hot water inlet pipe 35, and then is delivered to the spray hole 2213 of the brush head 22 through the cold and hot water pipes 37 and the water gun 2112 to clean the surface to be cleaned.

[0097] When cleaning curved surfaces (such as the outer wall of a pot), such as Figure 3 and Figure 4 As shown, the front of the outer brush disk 222 is flush with the front of the inner brush disk 221. Since the height of the outer brush strip 2221 is greater than the height of the inner brush strip 2211, the surface of the brush head 22 forms a concave structure.

[0098] When cleaning the inner curved surfaces (such as the inner wall of a pot), such as Figure 5 and Figure 6 As shown, the outer brush disk 222 flips toward the housing 211 under the action of the inner curved surface, so that the outer brush strip 2221 can freely conform to the state of the curved surface;

[0099] (2) After cleaning, first adjust the angle between the handle 212 and the housing 211 to 90°, then hold the handle 212 and put the entire cleaning brush 2 into the storage box 112, then close the box cover 113, and finally start the cleaning brush 2. The drive mechanism 23 drives the brush head 22 to rotate, and at the same time the cleaning medium supply device 3 supplies cleaning water to the cleaning brush 2 and sprays it out from the spray hole 2213 to rinse the brush head 22. The wastewater is discharged through the drain port 1122, thereby realizing the self-cleaning of the brush head 22.
