Description

Technical Field

[0001] The utility model relates to the technical field of cleaning and sanitary equipment, in particular to a multifunctional cleaning brush head and a cleaning main machine. Background Art

[0002] Pets refer to creatures that people keep for spiritual purposes rather than economic purposes. Traditional pets refer to mammals or birds, which are kept for entertainment and companionship. In real life, pets include fish, reptiles, amphibians, insects, and even plants, which are used for viewing, companionship, and to relieve people's mental stress. Among them, the most commonly kept are hairy animals such as cats and dogs, which are loved by many people because of their comfortable feel.

[0003] However, owners of hairy pets often complain and feel upset about many problems, such as hair loss due to seasonal changes, various tangles caused by dust in the hair, colds and breeding of bacteria due to not wiping the pets clean in time after bathing.

[0004] At present, there are vacuum cleaners specially designed for pets on the market. The vacuum cleaners not only have the vacuuming function of conventional vacuum cleaners, but also have a brush head specially designed for pets, which is connected to the air inlet of the vacuum cleaner for use.

[0005] A Chinese patent document with publication (announcement) number CN201523596U discloses a vacuum cleaner that can comb animal fur, the vacuum cleaner comprising a main body; the main body comprising an air inlet, an air inlet channel, a vacuum source motor, an air outlet channel and an air outlet, the air flow entering the main body passes through the air inlet, the air inlet channel, the vacuum source motor and the air outlet channel in sequence, and the gas is finally discharged through the air outlet; the vacuum cleaner also comprises a connecting pipe and a toothbrush, the bottom of the toothbrush is provided with comb teeth and an opening; an air outlet plate is provided at the air outlet, and an air outlet nozzle is provided on the air outlet plate; the two ends of the connecting pipe can be respectively connected to the air outlet nozzle and one end of the toothbrush, so that when the vacuum cleaner is working, the air flow discharged from the air outlet nozzle passes through the connecting pipe and is blown out from the opening of the toothbrush.

[0006] The above structure mainly connects one end of the connecting tube to the end, and the other end to the nozzle on the air inlet or the air outlet plate. Thus, the vacuum cleaner can also blow air to the outside. However, it can only choose one mode, either vacuuming or blowing air. It is limited to combing and sucking the pet's hair at the same time, or combing and drying the hair at the same time, and cannot solve the problem of how to comb, suck and dry the pet's hair at the same time.

[0007] In real life, pets need to be combed and blow-dried. In this process, the hair is easily blown around, and pets often move around during the process of being blow-dried. Therefore, the current blow-drying equipment forces the operator to stop in the middle of the process to comfort the pet, making it difficult to carry out the blow-drying work smoothly.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 6 In an embodiment of the utility model, a multifunctional cleaning brush head is used to be connected to a cleaning host 60 for auxiliary cleaning, including a hose portion 11 and a brush head portion 20. One end of the hose portion 11 is connected to the cleaning host 60 through a pipe or duct, and the other end thereof is also connected to the brush head portion 20 through a pipe or duct. A suction nozzle 22 is provided at one end of the brush head portion 20 away from the hose portion 11. The suction nozzle 22 is used to suck in external liquid or dust under the drive of the negative pressure airflow of the cleaning host 60.

[0036] Specifically, the cleaning brush head 10 of the vacuum cleaner is usually connected to the cleaning host 60, and the cleaning host 60 may be provided with a clean water tank 62, a dust box 63, a motor and a fan, wherein the fan, the dust box 63, the hose and the cleaning brush head 10 are connected to each other through pipes or pipelines, so that after the motor is turned on, the fan can be driven to generate airflow, and external liquids, dust or garbage and other debris are sucked into the dust box 63 through the cleaning brush head 10, thereby achieving the effect of cleaning external objects.

[0037] Secondly, for cleaning the pet's hair, the cleaning brush head 10 can be used to comb the pet's hair, and the suction nozzle 22 can absorb the combed hair to prevent the hair from flying around and improve the comfort of pet care.

[0038] like Figures 1 to 4 As shown, preferably, a mouth cover 23 is provided on the side of the suction nozzle 22 away from the brush head 20, and the mouth cover 23 is detachably fixed to the brush head 20 for cleaning the suction nozzle 22 after disassembly; a scraper 24 is provided at a position of the mouth cover 23 close to the suction nozzle 22, and the scraper 24 is detachably fixed to the mouth cover 23 for scraping off water stains on the cleaned object.

[0039] Specifically, since some pets have relatively long hair that is easy to block the suction nozzle 22, a mouth cover 23 can be set at the position of the suction nozzle 22. After the hair is blocked, the mouth cover 23 can be removed to replace or clean the suction nozzle 22. In addition, the suction nozzle 22 can be set relatively wide to increase the area for sucking hair, while reducing the suction force to prevent accidental injury to the pet. Figure 6As shown, the mouth cover 23 can be set as a larger cover plate, which is directly buckled on the side of the junction of the suction nozzle 22 and the brush head 20, so that even after the sucked hair is accumulated, it is not easy to block the airflow, but can be accumulated into a relatively large area, and then cleaned at one time. The scraper 24 can also be disassembled and cleaned or replaced. The scraper 24 can mainly be used on flat surfaces such as tiles or glass, and has a very good cleaning effect on water droplets or water stains. It can also allow the suction nozzle 22 to absorb more liquid and enhance the cleaning effect.

[0040] like Figures 1 to 3 As shown, preferably, in order to dry pet hair or other surfaces, the brush head 20 is also provided with a blowing assembly 30, an air inlet 25 and an air outlet 27. The blowing assembly 30 is fixedly connected to the inside of the brush head 20, and generates an airflow so that air flows in from the air inlet 25 and is then blown out from the air outlet 27.

[0041] Specifically, the air outlet 27 is arranged on a side of the suction nozzle 22 close to the hose portion 11, so that the airflow blown out of the air outlet 27 blows the external liquid or dust toward the suction nozzle 22, and then is sucked into the suction nozzle 22. By directly arranging the blowing assembly 30 on the brush head 20, the blowing assembly 30 is used to drive the airflow to flow in from the air inlet 25 and blow out from the air outlet 27, so that the drying operation can be directly performed on the brush head 20. At the same time, a corresponding comb plate 51 can also be arranged on the brush head 20, so that people can comb the pet's hair, blow dry the hair and absorb the hair at the same time, thereby avoiding the situation of hair flying around, reducing the combing time for the pet, reducing the stress response of the pet, and improving the efficiency of pet cleaning.

[0042] In addition, the air inlet 25 may also be provided with a filter 26. Preferably, the filter 26 may be made of a metal mesh with a plurality of micropores. The blowing assembly 30 may be provided using existing products in the prior art, such as a combination of a common AC motor or a DC motor, a heating coil or a heating plate, which is not limited here. The power for driving the blowing assembly 30 is preferably drawn from the inside of the cleaning host 60, and its power transmission cable 61 may be fixed by being installed on the outer wall of the hose portion 11, or may be installed in the inner space of the hose portion 11 and fixed.

[0043] Secondly, in order to fix the heating coil, it is preferred to cover a component with a certain heat insulation effect (not shown in the figure) to reduce the heat transferred to the brush head 20. In order to fix the motor, a soft rubber sleeve 31 with a certain elasticity can also be covered on the outer wall of the motor, so that the soft rubber sleeve 31 is fixed between the motor housing and the inner wall of the brush head 20, which can not only stabilize the motor, but also play a certain shock-absorbing role on the vibration of the motor, thereby reducing the vibration noise of the motor.

[0044] like Figure 2 and Figure 3 As shown, preferably, the air outlet 27 is further provided with a check valve 28 , and the check valve 28 is detachably fixed to the side wall of the air outlet 27 to prevent liquid from passing through the air outlet 27 and entering the interior of the blowing assembly 30 .

[0045] Specifically, the check valve 28 can preferably be installed using products such as rubber slow-closing check valves 28, back-pressure flexible check valves, duckbill check valves 28, etc. in the prior art, so that the check valve 28 can be in a closed state in the initial state, thereby preventing the liquid from passing through the air outlet 27 into the interior of the blowing assembly 30. After the blowing assembly 30 is in operation, under the influence of the high-pressure airflow, the check valve 28 can open to a certain angle so that air can be blown out from the air outlet 27. The detachable check valve 28 can be disassembled and separated for cleaning at ordinary times, and can also be replaced after being used for a period of time when the effect or elasticity of the check valve 28 deteriorates. In addition, if Figure 2 As shown, the relatively narrow outlet of the check valve 28 can further increase the flow rate of the airflow when it is blown out, thereby further enhancing the cleaning effect of the airflow on external objects.

[0046] like Figure 1 and Figure 3 As shown, preferably, an air inlet rubber cover 32 is provided at the air inlet end of the blowing assembly 30, and the air inlet rubber cover 32 is sleeved on the air inlet end of the blowing assembly 30 to prevent liquid from passing through the air inlet 25 and entering the blowing assembly 30; the air inlet rubber cover 32 is also provided with an air inlet slit 33, and the air inlet slit 33 is opened at a certain angle under the drive of the negative pressure airflow of the blowing assembly 30 to allow air to enter the blowing assembly 30.

[0047] Specifically, the air inlet rubber cover 32 is preferably made of soft rubber with a certain elasticity, so that it can maintain a sealing effect on the air inlet end in the initial state, and after the fan is running, it can be pushed by the airflow and deformed to a certain extent, so that air can enter the air inlet end. In addition, the air inlet slit 33 is preferably set in a cross shape, so that it is easier to open a certain opening under the action of the airflow to allow air to enter. The side wall of the brush head 20 is located between the air inlet 25 and the air inlet end of the blowing component 30. The water leakage port 21 is used to flow out water droplets entering from the air inlet 25 to prevent water droplets from entering the blowing component 30.

[0048] like Figures 1 to 3 As shown, preferably, an air outlet rubber cover 34 is also provided at the air outlet end of the blowing assembly 30, and the air outlet rubber cover 34 is rotatably connected to the blowing assembly 30 and openably and closedly connected to the air outlet end of the blowing assembly 30, thereby preventing liquid from passing through the air outlet 27 and entering the blowing assembly 30.

[0049] Specifically, in order to enhance the waterproof effect of the air outlet, it is preferred to set the air outlet rubber cover 34 as a whole without a slit, and make it relatively tightly buckled on the air outlet through the elastic force of the spring 36. The air outlet rubber cover 34 is initially buckled on the air outlet of the blowing assembly 30, and forms a sealing effect on the air outlet to prevent water vapor or water droplets from entering. The edge of the air outlet rubber cover 34 can be rotatably connected to the outer wall of the blowing assembly 30 in the form of a rotating shaft 35, and preferably the upper edge is rotatably connected, and then the air outlet rubber cover 34 can be flipped up, so that the airflow at the air outlet can be blown downward from the air outlet 27.

[0050] Secondly, in order to enable the air outlet rubber cover 34 to maintain the sealing effect on the air outlet end in the initial state, it is preferred that a spring 36 can be set at the position of the rotating shaft 35 where the air outlet rubber cover 34 is rotatably connected to the blowing component 30, so that the air outlet rubber cover 34 can close the air outlet end under the action of elastic force. It can be understood that the elastic force of the spring 36 should not be set too large, so that the air outlet rubber cover 34 can open the air outlet end after rotating a certain angle under the push of high-pressure gas after the blowing component 30 is running, so that air can be blown out from the air outlet end. Its elastic force should not be set too small either. When the blowing component 30 stops running, the air outlet rubber cover 34 can rotate back under the action of elastic force and close the air outlet end again, thereby preventing water vapor, water mist or water droplets from entering the blowing component 30.

[0051] like Figures 3 to 5 As shown, preferably, the brush head 20 is also provided with a water spray assembly 40, and the water spray assembly 40 is provided with a water pipe 41 and a nozzle 42, and the nozzle 42 is detachably fixed to the brush head 20, one end of the water pipe 41 is connected to the water pump in the cleaning host 60, and the other end of the water pipe is connected to the nozzle 42, so that the water pumped out by the water pump passes through the water pipe 41 and is sprayed from the nozzle 42.

[0052] Specifically, in order to achieve the water spraying effect, a clean water tank 62 should be provided in the cleaning host 60, wherein the water pump can extract the liquid in the clean water tank 62, pass through the water pipe 41 and then spray it from the nozzle 42. The water pipe 41 preferably passes through the inside of the hose portion 11, thereby connecting the nozzle 42 and the water pump of the cleaning host 60. The nozzle 42 is preferably provided with a plurality of nozzles 42 with small holes, so that the sprayed water flow can be scattered and cover a larger area. In addition, the nozzle 42 is preferably arranged on the side of the air outlet 27 close to the hose portion 11, so that after the water droplets clean the surface of the object, they can be sucked away by the negative pressure generated by the suction nozzle 22 to complete the cleaning operation. It can be understood that a water pump needs to be provided inside the cleaning host 60, and the water pump is connected to the nozzle 42 through the water pipe 41, so as to spray water on the external object and enhance the effect of the cleaning operation.

[0053] like Figure 4 and Figure 5 As shown, preferably, the brush head 20 is further provided with a comb plate 51, which is detachably fixed to the brush head 20 and located between the air outlet 27 and the suction nozzle 22, and the comb plate 51 is provided with a plurality of comb teeth for combing external objects or hair.

[0054] Specifically, in order to be able to brush or comb different pets or different hair types, lengths, etc., the comb plate 51 can be set to be detachable or replaceable, for example, different types such as long tooth plates, short tooth plates, dense tooth plates or sparse tooth plates can be set. It is mainly used when cleaning blankets or pet hair, and can be removed when cleaning other areas. A bristle plate 52 can also be set on the brush head 20, and the bristle plate 52 can also be removed or replaced. The bristle plate 52 is mainly used when cleaning the surface of objects such as sofas. The bristle plate 52 is preferably installed on the side of the nozzle 42 close to the hose part 11, so that the sprayed water droplets can be brushed to further enhance the cleaning effect.

[0055] Secondly, the comb plate 51 is preferably installed between the air outlet 27 and the suction nozzle 22, so that during the combing process, the air outlet of the blowing assembly 30 can blow the combed hair or dust to the suction nozzle 22, so that the suction nozzle 22 can directly suck away the hair or dust. In addition, the comb plate 51 can also be set at other positions of the brush head 20, such as between the air outlet 27 and the nozzle 42, so as to facilitate combing the water mist sprayed by the nozzle 42, further improving the cleaning effect of the water mist. In addition, the arrangement relationship between the comb plate 51, the air outlet 27, the nozzle 42 and the bristle plate 52 can also be replaced accordingly as needed, so that the cleaning brush head 10 can achieve more cleaning functions or cleaning effects.

[0056] like Figure 1 , Figure 2 and Figure 6 As shown, preferably, the brush head 20 is also provided with a control component 12, which is fixed to the outer wall of the brush head 20 and electrically connected to the control module of the cleaning host 60. The control component 12 is provided with a display screen and control buttons, so as to control the cleaning host 60 or the cleaning brush head 10.

[0057] Specifically, for ease of use, the main control buttons can be set on the brush head 20, which can be physical buttons, touch buttons, or waterproof buttons. A display screen can also be set to display the operation information of the cleaning host 60. The cleaning host 60 is preferably provided with a control module, and the control module can use related products in the prior art, such as a control chip, a power module, a drive module, a switch module, etc., so as to facilitate people to control and use the cleaning host 60 or the cleaning brush head 10.

[0058] When in use, first turn on the operation switch of the cleaning host, the motor runs, the fan rotates, and negative pressure is generated, so that the airflow enters the cleaning brush head from the suction nozzle of the cleaning brush head, and then enters the interior of the cleaning host through the corresponding pipeline for corresponding filtration and discharge, so that the cleaning brush head can absorb and clean external dust or water droplets and other debris. At the same time, the blowing component on the cleaning brush head can also be started, and the airflow blown by the blowing component is discharged from the air outlet at a high speed, so that the airflow can blow external dust, water droplets, hair and other debris, so that it is easy to be absorbed by the negative pressure generated by the suction nozzle of the cleaning brush head, thereby improving the cleaning effect.

[0059] Secondly, you can also use the nozzle part of the water spray component to spray water mist to moisten or clean external objects or pet hair, and then use the high-speed airflow of the blowing component to blow and clean, and the negative pressure suction and cleaning of the suction nozzle part to further improve the cleaning effect. At the same time, it can also optimize the cleaning environment and prevent dust or hair from flying around, affecting the cleaning experience of the cleaning staff.

[0060] Again, it is understandable that the suction function of the cleaning brush head, the blowing function of the blowing component and the water spraying function of the water spraying component can all operate independently or simultaneously, and can be controlled according to the corresponding conditions of the objects or animals being cleaned, so that it can not only optimize the cleaning effect, but also meet the optimization of various cleaning methods, making the cleaning process more comfortable for the cleaning personnel, while reducing the stress response of the animals being cleaned.

[0061] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
