Description

The present invention relates to a hair collecting device for collecting a pet's hair and a structure of a hair collecting device stand.

Familiar animals that have lived in harmony with humans for a long time are called companion animals. Hereinafter, the companion animal shall be referred to as a pet.
In recent years, pets have become recognized as part of the family, and pets are becoming more important. Representatives of pets include mammals such as cats, dogs, rabbits, squirrels, hamsters, guinea pigs, and ferrets.

In the pet industry, efforts are being made in various fields to deal with the coexistence of humans and pets, and to deal with the super-aging society of both humans and pets.
For example, with regard to pet food, the provision of pet food considering additives corresponding to the age group of pets is progressing, which leads to the aging of pets.
In addition, according to the national policy, the target for maintaining the health of the elderly, the so-called healthy life expectancy, is +1 year old. It has been verified from the data from the medical society that symbiosis between humans and pets is indispensable for this purpose. It has also been confirmed that the symbiosis between humans and pets also affects the life span of humans.

In the symbiosis between humans and pets, the handling of hair that has fallen out of pets has become an issue. That is, it is troublesome to collect the coat of a pet that has been scattered in the air or has fallen on the floor, and the collection work also requires labor. Conventionally, the hair that is likely to come off and the hair that has already come off on the body surface of the pet are collected using a vacuum cleaner or a cleaning tool such as adhesive paper that is generally used at home. Was there. In addition, when brushing a pet, the hair that is likely to be peeled off and the hair that has already been peeled off may be scattered on the surface of the pet's body. Therefore, there is a vacuum cleaner with a brush attached to the tip of the nozzle for pets.

According to Patent Document 1, by providing a brush body at the front end and a hose communicating with the suction machine of the vacuum cleaner at the rear end, hair sucking for pets that suppresses the scattering of pet hair that occurs when brushing pets is suppressed. Brushes have been proposed.

Japanese Unexamined Patent Publication No. 2001-190174

The technique described in Patent Document 1 has a problem that the suction force is too strong because a vacuum cleaner is used for sucking the hair. As a result, the coat of the pet is pulled more than necessary, which is equivalent to the act of forcibly pulling out even the coat that has not yet been removed, and there is a problem that the pet is stressed.
Further, the technique described in Patent Document 1 has a problem that the driving noise is loud because a vacuum cleaner is used for sucking the hair. This puts stress on the sound-sensitive pet, and there is a problem that the pet escapes even when trying to brush.
Further, in the technique described in Patent Document 1, since the bristle is long, the bristle easily hits the skin of a pet with short hair type, and the irritation given to the skin is too strong, so that there is a problem that the pet is easily stressed. there were.

The present invention has been made against the background of the above-mentioned problems, and is a cover for mounting a hair recovery device capable of efficiently recovering a pet's hair while suppressing stress applied to the pet. It is intended to provide a hair collection device stand.

The hair collection device stand according to the present invention is installed on a suction air passage portion having a suction port formed at one end thereof and on the other end side of the suction air passage portion on the opposite side of the suction port. A housing having an opening for inserting a hair recovery device having a fan portion for generating a flow of air sucked from the suction port and a power supply portion for supplying power to the fan portion, and the housing. It is provided with a suction fan portion which is arranged inside the housing and causes an air flow from the opening toward the inside of the housing.

According to the present invention, there is provided a hair recovery device capable of efficiently sucking and recovering peelable hair and already peeled hair adhering to the body surface of a pet while suppressing stress applied to the pet. The hair collected in the hair collection device in that state can be moved to the hair recovery device stand.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings including FIG. 1, the relationship between the sizes of the constituent members may differ from the actual one. Further, in the following drawings including FIG. 1, those having the same reference numerals are the same or equivalent thereof, and this shall be common to the entire text of the specification. Furthermore, the forms of the components represented in the full text of the specification are merely examples, and are not limited to these descriptions.

In the embodiment, among pets, especially cats will be described. First, the physical and ecological characteristics of cats will be described. FIG. 1 is a schematic diagram schematically showing how a cat's coat grows. FIG. 2 is a graph showing the relationship between the sound pressure level of a vacuum cleaner generally used in the home and the hair recovery speed. FIG. 3 is a graph showing the relationship between the sound pressure level and the air volume of a vacuum cleaner generally used in a home.

On average, about 600 coats grow on the body surface of a cat per 1 cm square. As shown in FIG. 1, the cat's coat includes guard hair, orn hair, and down hair. The average length of a cat is about 40 ± α cm from the neck to the base of the tail. The average waist circumference of a cat is 30 ± α cm. Therefore, the surface area of the body of the cat is 40 × 30 = 1200 cm ² . Therefore, since there are 600 pieces in a 1 cm square, 1200 x 600 = 720000 pieces. However, since there is a dense part of the coat depending on the body part of the cat, it is considered that about 800,000 to 1,000,000 coats are present on the body surface as a result. As a comparison, the number of human hairs is about 100,000.

One human hair grows from one pore, but a cat's coat grows about six from one pore, as shown in FIG. And the cat's coat grows completely in about 3 months. In other words, if you have a large number of cats, the coats of the number of cats you have will be scattered on a daily basis. For comparison, dogs also have a similar coat growth.

Comparing the thickness of the coats of dogs and cats, the diameters of the coats of cats are 0.02 mm to 0.03 mm, whereas the diameter of the coats of dogs is 0, although they are both average. It is 0.05 mm to 0.1 mm. The wide range between the minimum and maximum diameters of a dog's coat is due to the fact that the thickness of the coat varies depending on the type of dog.
The average length of each coat of cats is 3 cm to 4 cm for short coats and 5 cm to 8 cm for long coats.

The coat is mainly composed of a protein called "keratin". At the base of the hair follicle, there is an organ that secretes sebum called the sebaceous gland. Hair follicles are sac-like epithelial tissues that enclose hair roots.
However, the cat's coat is soft, and the sebum secreted from the sebaceous glands does not sufficiently spread to the coat, so that the cat's coat is always in a soft hair state. On the other hand, dogs have thicker coats than cats, so sebum is more likely to spread over the coats.

Since cats are animals that act alone, they perform careful self-grooming to prevent their own body odor. On the other hand, since dogs are animals that behave in multiple ways, they need body odor in terms of ethology, and since having body odor is not a problem, self-grooming is not performed much.
That is, the cat has more time to perform grooming behavior to remove odors and stains and maintain cleanliness by licking its own body surface, and inevitably swallows its own coat. In addition, due to self-grooming, hair scattering is also occurring at the same time.

When a cat swallows its coat and the hairballs accumulate too much in the body, it becomes "hairball disease". Cats vomit hair that cannot be processed by the body by swallowing, but when "hairball disease" occurs, symptoms such as nausea, loss of appetite, constipation, or diarrhea occur, and when it gets worse, laparotomy is required.

Cat breeders often brush their bodies as part of their communication with the cat, in addition to the cleanliness of the cat's own body and the ability to prevent swallowing of the coat, in order to maintain the nature of the cat. By this brushing, unnecessary hair can be collected, and in addition, the comfort of the cat itself can be improved by stroking the body of the cat by the breeder. In other words, by brushing, hair recovery and stress countermeasures can be realized at the same time.
In addition, recent studies have revealed that brushing reduces stress in cats and at the same time produces a stress-reducing effect by secreting the hormone "oxytocin" in the breeder's own brain.

Conventionally, the scattered hair has been collected by using a vacuum cleaner or a cleaning tool such as adhesive paper that is generally used in the home. Also, there were few brushes that were specialized for animal species, especially cats. Most of the brushes for pets that are generally on the market are basically also used as "dogs". In other words, there were very few cat-specific brushes that corresponded to the constitution and personality of the cat. In extreme cases when using a brush that doubles as a "dog", brushing puts the cat in a stressed state. As a result, the cat was supposed to dislike the brushing act itself.

In addition, some breeders try to recover their coat by pressing adhesive paper against the cat's body surface, ignoring the nature of the cat. This act is equivalent to the act of forcibly pulling out the coat, causing pain, etc., and may be regarded as an abusive act against cats.

Also, commonly used vacuum cleaners have a basic task of collecting debris and are equipped with a motor that rotates at high speed to produce the fluid needed to suck in the debris. As shown in FIGS. 2 and 3, such a vacuum cleaner that rotates at a high speed and produces a strong suction force generates a loud noise due to the rotation. The sound generated by a vacuum cleaner has become a social problem as noise. In addition, as the motor rotates, various peak frequencies such as a sound due to an electromagnetic component, a sound due to a rotation component of the motor, and a fluctuating sound when air passes through the blades are also generated at the same time. Moreover, it is a well-known fact that the generated sound extends to a high frequency band, which is also an ultrasonic band of 20 kHz or higher.

Here, the results of investigating the stress response to the hearing and sight of the cat by experimental verification will be described. There are two types of cats, short-haired and long-haired, and unless there is a special reason such as obesity, the appearance dimensions and weight of domestic cats are approximately the same on average.
However, there are individual differences in "hearing" and "visual acuity" in consideration of age group and the like.

There are various opinions about the physical ability of cats, but it is not certain because there is not as much research as dogs. Since dogs have a strong obedience to humans, they can reliably obtain responses to various tests and studies, and are often used as research subjects, so various results have been announced. On the other hand, cats have less obedience to humans, so they do not respond to the same tests as dogs, and they also act as stress responses to external factors from the tests. Therefore, in cats, it is difficult to obtain test results and it is difficult as a research subject, so the research report contents that have been said before and the current research results are often different.

Therefore, we conducted an experiment to confirm the stress state of cats with respect to sounds, objects, colors, etc. from physical reactions. In the case of a cat, the stressed state can be easily confirmed by the physical appearance movement. For example, the stress state can be confirmed by physical appearance movements such as shaking the tail greatly, raising the coat upside down, turning the ears sideways, and running away as soon as the object is seen. If you run away as soon as you see an object, you can judge that you have a high learning ability for the object.
The number of cat samples in this experiment was 30, and there is no dependence on the sex of the cat, the age of the cat, the type of coat of the cat, etc., but the common point is that the cats are bred indoors. ..

In the hair recovery by any means, the cats caused the stress reaction as described above, and all the cats could not recover the hair without feeling stress. Any means is a vacuum cleaner, an adhesive paper, and a brush that also serves as a "dog".
It was also found that the loud sound was a major stress factor.
From the above, none of the means was configured from the cat's point of view, and there was no means for collecting hair exclusively for cats.

The experimental results of the auditory characteristics for the sound of cats are as follows.
It was found that the sound pressure level must be less than 30 dB when using a device that produces sound in a place close to the cat in real space, here a vacuum cleaner. In particular, it was found that 20 dB ± 3 dB or less is essential when using the vacuum cleaner in contact with the cat's body.
It was found that the stress response tends to be small in the frequency band when the sound pressure level is 30 dB or less with respect to the low frequency band of 1 kHz or less, particularly 800 Hz or less. In the case of 800 Hz or higher, the physical reaction to the sense of hearing could be visually confirmed from the sound pressure level of around 25 dB. In some cases, it was also confirmed that the avoidance action was started in search of a distance or place where no sound could be heard.

In addition, when a sound with a specific frequency band, for example, 1/3 octave, is output in a place close to a cat, the behavior is such that it can be heard from around 20 dB in the band of 10 kHz or higher, and it can be heard up to around 80 kHz. It turned out to show behavior that seems to be.
Furthermore, it was found that the peak protrusion amount must be 10 dB or less from the base level at 1 kHz or less.
From this, it was found that it is necessary to consider the operating frequency for the power supply.

The experimental results of the visual characteristics of cats are as follows.
It was found that cats react sensitively to the size of objects. It was found that when the breeder approaches the cat with, for example, a 500 ml PET bottle, he does not perform evasive behavior relatively. It is probable that this is because the cat decided that it would not harm itself.
However, as the size increased by 5 cm, the behavior of avoiding things came to be seen. In other words, it turns out that cats are very cautious about things that are larger than their own bodies, especially those that move. For this reason, in a vacuum cleaner used in a general household, not only the sound but also the size of the vacuum cleaner gives stress to the cat. Vacuum cleaners used in ordinary households also include cordless handy cleaners.

The experimental results of the visual characteristics for the color of the cat are as follows.
As for the color, the reaction was confirmed using a 500 ml PET bottle.
Cats are generally said to be colorblind, but it was found that when seven colors such as the rainbow were used, they tended to have no movement behavior for cool colors rather than warm colors. The reaction to white objects also tended to be the slowest.
From this, it is considered that the cat also recognizes the color of the object.

From the above experimental results, it can be assumed that the equipment close to the cat needs the following specifications.
As a specification for the sound generated from the device, the frequency band is an operating sound up to 800 Hz or less, and the sound pressure level is 25 dB or less.
As a specification for the size of the device, the size of a general 500 ml PET bottle is maximized.
The specifications for the color of the device shall be white or gray.

If the equipment configuration satisfies such specifications, it is expected that the stress given to the cat will be reduced. By developing a device based on this result, it is possible to develop a device that can efficiently collect hair before it is scattered in the air and reduce stress on pets and breeders. In other words, the development of a device that relaxes the pet by a movement similar to the movement of a person stroking the pet and at the same time effectively promotes the collection of the pet's hair, and at the same time, the breeder himself can obtain the stress reduction effect by interacting with the pet. It will be possible.

It is also known that the body of a cat has multiple acupuncture points. It has been clarified academically that stimulating this acupoint at the same time as brushing contributes to improving the relaxation of cats and improving the health of cats. For example, see http://cat-guide.net/wp/wp-content/uploads/2015/05/Cat body acupoint.jpg.

When the frequency band is 800 Hz, the power supply frequency is related, so it is necessary to pay sufficient attention to the frequency of the power supply to be operated, the harmonic component, and the sound pressure level at that time. Considering this point, a DC power supply drive using a battery or the like is effective as a power supply.

FIG. 5 is a rear view of the hair recovery device 100 according to the embodiment. FIG. 6 is a front view of the hair recovery device 100 according to the embodiment. FIG. 7 is a side view of the hair recovery device 100 according to the embodiment. FIG. 8 is a top view of the hair recovery device 100 according to the embodiment. 9 to 11 are explanatory views of the cross-sectional structure of the hair recovery device 100 according to the embodiment. FIG. 9 corresponds to the cross section of the SS portion of FIGS. 5 and 6, and this cross section is referred to as a first cross section. FIG. 10 corresponds to the cross section of the TT portion of FIG. 7. FIG. 11 corresponds to the cross section of the UU portion of FIG. The hair recovery device 100 will be described with reference to FIGS. 4 to 11.

The hair recovery device 100 is configured in consideration of the physical and ecological characteristics of the cat. Therefore, here, a cat will be described as an example of a target pet.
The hair recovery device 100 can relax the cat, reduce stress not only on the cat but also on the user by communicating with the user, and can reduce hair scattering by efficiently collecting the hair. It is something like that. Specifically, the hair recovery device 100 is configured to have a size that can be held by the user with one hand, and sucks and collects the hair that is likely to peel off and the hair that has already peeled off and adheres to the body surface of the pet. be.

First, the premise for configuring the hair recovery device 100 will be described.
The hair recovery device 100 is a lightweight material having a total weight of 250 g or less. Further, the hair recovery device 100 has a total length of 30 cm or less. The total length means the length from the lower end to the upper end of the hair collecting device 100 shown in FIGS. 5 to 7.
The hair recovery device 100 has a length of 15 cm or less in the width direction. The length in the width direction means the length of the longest portion in the plan view state shown in FIG.

The hair recovery device 100 has a sound pressure level of 30 dB or less and a peak protrusion amount of 5 dB or less.
Further, it is desirable that the hair recovery device 100 has a white or gray color in appearance. However, it does not have to be composed of only one color. Moreover, at least one such as a pattern and a character may be used as a decoration. Further, marks, characters, logos and the like may be decorated with engravings and the like.

On the premise of these, a specific configuration of the hair recovery device 100 will be described.
As shown in FIGS. 4 to 8, the hair recovery device 100 includes a suction air passage unit 10 and a drive unit 40. The hair recovery device 100 is configured by integrally combining a suction air passage portion 10 and a drive portion 40. The suction air passage portion 10 forms an air passage through which the air flowing in from the suction port 25 flows. The drive unit 40 includes a fan unit 50 (see FIG. 9) for sucking air from the suction port 25 and a power supply unit 60 (see FIG. 9) for driving the fan unit 50. The hair recovery device 100 is a device that collects hair by sucking the hair together with air from the suction port 25 by hitting the suction port 25 on the body of the cat.

The drive unit 40 includes a hair collection unit 45 on the suction air passage portion 10 side of the fan unit 50 for sucking hair together with air from the suction port 25. The hair collecting unit 45 is configured so that the hair sucked into the suction air passage unit 10 does not enter the fan unit 50.

The hair collection unit 45 is provided on the downstream side of the suction air passage unit 10 so as to communicate with the suction air passage unit 10, and collects the hair that has passed through the suction air passage unit 10. The hair collecting unit 45 is provided with a filter unit 42, and the hair is collected by the filter unit 42. The filter unit 42 circulates the air carrying the hair while collecting the hair. That is, the filter portion 42 serves to prevent the hair from entering the fan portion 50. If the filter portion 42 is detachable, it can be removed and washed.

The filter unit 42 is composed of, for example, a mesh filter. The dimensions of the mesh filter shall be a quadrangle with a 5 mm square to 7 mm square or a circle with a radius of 2 mm to 3 mm, and the opening area shall be 50% or more. The filter portion 42 is not limited to the above-mentioned specific dimensions, and may be any one as long as the hair does not get entangled with the filter portion 42 and the collected hair can be easily removed. Since the length of the cat's coat is as described above, the coat can be reliably recovered if the size and opening area of the mesh filter are used, and no pressure loss is given to the rotation of the fan portion 50 on the downstream side. The fan unit 50 can be operated.

The material of the mesh filter constituting the filter unit 42 is not particularly limited, and may be any material made of metal, resin, paper, or the like.

The fan portion 50 generates an air flow for sucking hair, and is composed of one of a sirocco fan or an axial fan having a wind speed of 5 m / s or less. Conventionally, when the fan unit 50 is driven, the frequency due to the rotation component of the fan unit 50 appears as a protruding peak. However, by using the sirocco fan or the axial flow fan as the fan section 50, it is possible to suppress the frequency generated by the rotational component of the fan section 50 among the frequencies of the sounds produced by the fan section 50. An exhaust port 55 is formed in the fan portion 50. As a result, air flows from the suction port 25 to the exhaust port 55. In FIG. 4, the details of the exhaust port 55 are omitted. Further, as shown in FIG. 7, the exhaust port 55 is provided with a guard portion 51 so that a human finger or the like does not enter. The fan section 50 will be described in detail later.

The power supply unit 60 is provided behind the fan unit 50, that is, on the side of the fan unit 50 opposite to the hair collection unit 45, and supplies drive power to the fan unit 50. For example, a switch 61 and a fan rotation speed volume (not shown) may be connected to the power supply unit 60. The switch 61 functions as an ON / OFF switch for starting or stopping the power supply to the fan unit 50 by being operated. A DC power supply of up to 24 V is required to drive the fan unit 50 having a wind speed of 5 m / s or less. When the switch 61 is operated, the power supply unit 60 supplies a maximum of 24V DC power supply to the fan unit 50.

The fan rotation speed volume is operated by the user when adjusting the rotation speed of the fan unit 50. If the fan rotation speed volume is provided, when the fan rotation speed volume is operated, the power supply unit 60 starts supplying power of about 9V to the fan unit 50, and the voltage supplied to the fan unit 50 is supplied. By changing it, it becomes possible to adjust the strength of rotation of the fan portion 50 step by step. Depending on the condition of the body surface of the cat, the wind speed may be increased or decreased. Therefore, in order to make it possible to increase or decrease the rotation speed of the fan unit 50, the fan unit 50 controls the rotation speed. It should be possible. Specific examples of the fan rotation speed volume include a strength switch or a large / small switch. However, when the rotation of the fan portion 50 is set to a constant speed, it is not necessary to provide a volume for the fan rotation speed.

The power supply for operating the fan unit 50 is a DC power supply. Therefore, it is preferable that the power supply unit 60 has a battery capacity of about 300 mA at a maximum of 24 V DC in consideration of the size and weight of the hair recovery device 100 and the one-time use time is about 5 minutes. Further, the drive unit 40 may be provided with a contact unit (not shown) to charge the rechargeable battery built in the power supply unit 60. The contact portion is composed of a positive contact portion and a negative contact portion. By making the hair recovery device 100 rechargeable, wiring with an external power source is not required for power supply to the hair recovery device 100, and since there is no wiring with an external power supply, it does not interfere with the brushing operation. The power may be supplied by a dry battery, or may be supplied by wiring, although it interferes with the brushing operation.

In the case of a rechargeable type, only the hair recovery device 100 or the power supply unit 60 may be mounted and stored in a charging box (not shown), and charging may be performed during storage. Further, according to the hair recovery device 100, the operation time can be shortened and the rotational capacity of the fan portion 50 can be reduced, so that the size of the rechargeable battery can also be reduced. By making the rechargeable battery smaller, the weight also becomes lighter. Further, the rechargeable battery may be charged by the hair recovery device stand 80 having a function as a charging device. The hair recovery device stand 80 will be described later.

The hair recovery device 100 does not particularly limit the installation position of the switch 61 and the fan rotation speed volume. For example, it may be provided on the back surface of the power supply unit 60, or may be provided so as to be aligned with the exhaust port 55 of the fan unit 50. Further, the switch 61 and the fan rotation speed volume may be provided at separate positions. Further, the size and shape of the switch 61 and the volume for the fan rotation speed are not particularly limited.

FIG. 12 is a schematic diagram schematically showing an enlarged internal configuration of the fan portion 50 of the hair recovery device 100 of the embodiment. The fan section 50 will be described in detail with reference to FIG. The fan portion 50 has an outer case 50A constituting the outer shell. Inside the outer case 50A, a fan 50a, a bell mouth portion 50b, and a guard portion 51 are installed.

The fan 50a is composed of a sirocco fan or an axial flow fan.
When the fan 50a is a sirocco fan that rotates at about 2000 rpm, the peak component of the sound frequency associated with the rotation occurs at around 33 Hz. If the fan 50a has 30 blades, the frequency of the NZ sound accompanying the rotation of the fan 50a is 990 Hz, and the peak protrusion amount of the sound pressure is 5 dB or less.

Further, when the fan 50a is an axial fan and the fan 50a rotates at about 2000 rpm, the peak component of the sound frequency accompanying the rotation occurs at around 33 Hz. Assuming that the fan 50a has six blades, the frequency of the NZ sound accompanying the rotation of the fan 50a is about 200 Hz. The frequency of the NZ sound is obtained by N × Z when N is the rotation frequency of the fan 50a and Z is the number of blades.

In order to keep the wind speed at the suction port 25 at 5 m or less, the opening area of the suction port 25 is set to about 2 m ² . By doing so, the size of the suction port 25 and the size of the main body are determined. Once the specifications of the fan 50a and the opening area of the suction port 25 are determined, the size of the hair collecting device 100 can be set to "palm size".

The bell mouth portion 50b is installed in a suction path 54 having an opening formed on the most upstream side of the fan portion 50, and serves to promote suction of air into the fan portion 50. The bell mouth portion 50b is located on the downstream side of the filter portion 42 of the hair collection portion 45 in the drive portion 40. The bell mouth portion 50b is attached to the outer case 50A via the end portion 50c. Providing the inner wall of the outer case 50A on the outer side of the end portion 50c is not particularly problematic, but providing the inner wall of the outer case 50A on the center side from the end portion 50c is arranged on the downstream side of the bell mouth portion 50b. A pressure loss will be given to the existing fan 50a. Therefore, the exterior case 50A is configured so that the inner wall is located outside the end portion 50c of the bell mouth portion 50b.

The surface of the outer case 50A facing the suction path 54, that is, the surface on the power supply unit 60 side is closed. An exhaust port 55 is formed on the upper side of FIG. 9 of the exterior case 50A. Therefore, the air sucked from the suction port 25 by driving the fan portion 50 is bent in the direction perpendicular to the outer case 50A and then discharged from the exhaust port 55 to the outside of the hair recovery device 100. The exhaust port 55 is formed at a position not suitable for the cat when the hair recovery device 100 is used. For example, as shown in FIG. 7, the exhaust port 55 may be formed on the upper surface of the paper surface. Further, the exhaust port 55 may be formed on the surface of the outer case 50A on the power supply unit 60 side as long as it does not interfere with the power supply unit 60.

The guard portion 51 prevents a human finger inserted into the exhaust port 55 from hitting the fan 50a. However, since air does not flow when the exhaust port 55 is closed, a mesh-shaped guard may be installed as the guard portion 51. The configuration of the guard portion 51 is not particularly limited, but a mesh-shaped guard that does not allow a human finger to enter may be used.

Next, the structure of the suction air passage portion 10 will be described.
The suction air passage portion 10 is a cylindrical body, and a suction port 25 is provided at one end portion, and a drive portion 40 is connected to the other end portion. The suction air passage portion 10 is formed so that the cross-sectional shape becomes smaller from the drive portion 40 side toward the suction port 25 side. Here, the cross-sectional shape refers to a shape in a cross section perpendicular to the central axis of the suction air passage portion 10 which is a cylindrical body. However, the cross-sectional shape of the suction air passage portion 10 is not limited to one that becomes uniformly smaller from the drive portion 40 side toward the suction port 25 side, and from the drive portion 40 side to the suction port 25 depending on the appearance design and the like. The cross-sectional shape may be partially enlarged on the way. The central axis of the suction air passage portion 10 is parallel to the z-axis shown in the drawing. The x, y, and z directions shown in each figure are common to each figure.

As shown in FIG. 7, the suction air passage portion 10 has a back surface portion 31 and a front surface portion 32. The back surface portion 31 is a portion on the y-direction side when the suction air passage portion 10 is divided by the virtual plane P. The front portion 32 is a portion on the opposite side in the y direction. The virtual plane P includes the central axis of the suction air passage portion 10 and is a plane parallel to the xz plane.

The suction air passage portion 10 may be configured to have a shape as shown in FIG. 7 when viewed from the side. In particular, the front portion 32 has a curved shape that is convex toward the virtual plane P in the side view. Therefore, when the suction port 25 is brought into contact with the cat's body, the front portion 32 is prevented from colliding with the cat's body. However, the shape of the front portion 32 in the side view is not limited to the shape shown in FIG. 7. In the embodiment, the back surface portion 31 has a shape symmetrical to the front surface portion 32 with respect to the virtual plane P except for the periphery of the suction port 25.

In the side view, the radius of the arc-shaped portion of the back surface portion 31 is in the range of 300 mm to 400 mm. By forming the back surface portion 31 in such a shape, the back surface portion 31 can be easily aligned with the cat's body, for example, the back or the abdomen.

A suction port 25, which is an inlet for sucked air, is formed at the end portion of the suction air passage portion 10 in the z direction, that is, the tip portion. The suction port 25 is formed on the central axis of the suction air passage portion 10 which is a cylindrical body. Further, the suction air passage portion 10 connects the suction port 25 to the fan portion 50 installed inside the drive unit 40 to form an air passage through which air flows. By driving the fan portion 50, an air flow is generated from the suction port 25 toward the fan portion 50. This air flow has the highest flow velocity in the central portion in the cross section perpendicular to the central axis of the air passage formed inside the suction air passage portion 10. Therefore, since the suction port 25 is located on the central axis of the suction air passage portion 10, it becomes easy to suck the hair from the suction port 25. In the embodiment, the central axis of the air passage coincides with the central axis of the suction air passage portion 10.

Further, in order to realize low noise, it is important to prevent turbulence or the like due to the air flow generated outside the substantially central portion of the flow path cross section of the suction air passage portion 10. For that purpose, it is necessary to position the substantially central portion of the flow path cross section of the suction port 25 and the substantially central portion of the suction path flow path cross section of the fan portion 50 on the same axis. From this point as well, it is desirable that the suction port 25 is formed on an axis located substantially in the center of the flow path cross section of the suction path of the fan portion 50. Further, the width of the suction port 25 is smaller than the width of the suction opening portion provided in the hair collecting portion 45 of the drive portion 40 and communicating with the fan portion 50. With this configuration, the wind speed distribution becomes substantially uniform at each point in the width direction of the suction port 25, and the hair collection efficiency is improved.

The suction port 25 is an area surrounded by two protrusions 21, a rear peripheral edge 22 and a front peripheral edge 23, and communicates the internal cavity 11 of the suction air passage portion 10 with the external space. ing. As shown in FIG. 8, the suction port 25 is a flat opening in the plan view of the hair recovery device 100. The longitudinal direction of the suction port 25 is parallel to the x direction and is on the virtual plane P. One protrusion 21 is provided at both ends of the suction port 25 in the longitudinal direction. The back side peripheral portion 22 is located on the back side of the peripheral portion of the suction port 25 and connects between the two protrusions 21. The front peripheral portion 23 is located on the front side of the peripheral portion of the suction port 25 and connects between the two protrusions 21. In the cross section shown in FIG. 9, the back surface side peripheral edge portion 22 is located farther from the fan portion 50 than the front surface side peripheral edge portion 23.

The protrusions 21 are arranged at both ends of the suction port 25 in the x direction, and are provided with the protrusion tips 26 facing in the z direction. In the embodiment, the protrusion tip 26 is located on the virtual plane P. As shown in FIG. 7, the protrusion 21 is formed so that the width on the suction port 25 side is wide and the width narrows toward the protrusion tip 26 in the side view, and the protrusion 21 has a substantially triangular shape in the side view. There is. In the side view, the back ridge line 27 located on the back side of the protrusion 21 and the front ridge line 28 located on the front side extend diagonally from the protrusion tip 26 to the suction port 25 side symmetrically with respect to the virtual plane P. The back ridge line 27 has an end on the suction port 25 side connected to the back peripheral edge portion 22. The front ridge line 28 has an end on the suction port 25 side connected to the front peripheral portion 23.

Further, as shown in FIGS. 5 and 6, the protrusion 21 is formed so as to have a wide width on the suction port 25 side and a narrow width toward the tip 26 of the protrusion in front view or rear view. It has a substantially triangular shape in visual or posterior vision. As shown in FIG. 5, there is a back ridge line 27 inside the protrusion 21 when viewed from the back side, and the back ridge line 27 is connected to the back side peripheral edge portion 22. On the outside of the protrusion 21, there is a side ridge line 29. The side ridge line 29 is smoothly connected to the side ridge line of the suction air passage portion 10.

As shown in FIGS. 5 and 6, the back surface side peripheral edge portion 22 has a curved shape with the first peripheral edge portion 22A as the apex, and the central portion 22a is convex and gently reverses in the z direction toward the protrusions 21 at both ends. It has a shape that goes down in the direction. The front peripheral edge portion 23 is parallel to the x direction.

As shown in FIG. 8, in the plan view state, that is, when the virtual plane P is the horizontal direction and the suction air passage portion 10 is viewed from the central axis direction, the central portion 22a of the rear peripheral portion 22 is the most y direction. It is positioned so as to protrude in the direction of the horizontal direction, and gradually descends in the opposite direction in the y direction toward the protrusions 21 at both ends. The central portion 22a of the peripheral edge portion 22 on the back surface side may have a curved shape convex in the y direction or a linear shape. Further, in the plan view state shown in FIG. 8, the central portion 23a of the front peripheral portion 23 is positioned so as to project in the opposite direction in the y direction, and gradually rises in the y direction toward the protrusions 21 at both ends. It has a shape. The central portion 23a of the front peripheral portion 23 may have a curved shape that is convex in the opposite direction in the y direction, or may have a linear shape.

As shown in FIG. 9, the suction port 25 surrounded by the rear peripheral portion 22, the front peripheral portion 23, and the two protrusions 21 is inclined and opened, and faces in the opposite direction in the y direction. .. That is, the suction port 25 is formed so that the rear peripheral portion 22 is located in the z direction with respect to the front peripheral portion 23. When the protrusion 21 passes through the central first peripheral edge 22A of the rear peripheral edge 22 and the central second peripheral edge 23A of the front peripheral edge 23 and the plane parallel to the x-axis is used as the suction port virtual plane Q, the protrusion 21 is formed. , The suction port protrudes from the virtual plane Q. In the embodiment, the front ridge line 28 of the protrusion 21 intersects the suction port virtual plane Q at an angle close to parallel. The back ridge line 27 of the protrusion 21 intersects the suction port virtual plane Q at an angle closer to a right angle than the front ridge line 28.

In the embodiment, the suction air passage portion 10 is configured by combining the suction port portion 20 and the air passage portion 30. The suction port portion 20 and the air passage portion 30 are integrally formed to form a tubular body. The suction port portion 20 and the air passage portion 30 are detachably configured. Further, it is desirable that the suction port portion 20 can be attached to the air passage portion 30 even if it is oriented in the opposite direction. That is, the connection portion of the suction port portion 20 has a plane-symmetrical shape with respect to the virtual plane P, and the connection portion of the air passage portion 30 also has a plane-symmetrical shape with respect to the virtual plane P. With this configuration, the suction port 25, which is obliquely opened in the opposite direction in the y direction in FIG. 9, can be directed in the y direction. By attaching the suction port 25 in the opposite direction, even in various situations such as the orientation of the cat's body and the hand holding the hair recovery device 100 of the user of the hair recovery device 100 is either the right hand or the left hand. The drive unit 40 can be used in a state of being oriented in a predetermined direction.

13 and 14 are explanatory views schematically showing an example of a usage state of the hair recovery device 100 according to the embodiment. FIG. 13 shows a cross section of the hair recovery device 100 in a used state, and corresponds to the cross section of the SS portion of FIGS. 5 and 6 as in FIG. 9. An example of the usage state of the hair recovery device 100 will be described with reference to FIGS. 13 and 14. In FIGS. 13 and 14, the movement of the hair recovery device 100 is indicated by the arrow A1, and the air flow is indicated by the arrow A2.

The user of the hair recovery device 100 operates the switch 61 of the hair recovery device 100 to turn on the power to the hair recovery device 100. The user holds the hair recovery device 100 with his / her own hand and brings the suction port 25 into contact with the body surface of the cat Ca. Then, the user moves the hair recovery device 100 along the direction of the coat of the cat Ca. The direction of the arrow A1 is the moving direction of the hair collecting device 100 at the time of hair collecting. By doing so, the hair is sucked into the suction air passage portion 10 from the suction port 25 of the hair recovery device 100.

That is, at this time, the hair that is likely to be peeled off and the hair that has already been peeled off, which are attached to the body surface of the cat Ca with which the suction port 25 is in contact, are sucked by the flow of air flowing into the suction port 25 from the outside. It is sucked into the inside of the part 10. The protrusion 21 is arranged on the tip side of the hair recovery device 100 with respect to the suction port 25, and is located on the body side of the cat Ca with respect to the hair surface 90 with which the suction port 25 is in contact at the time of use. Therefore, the protrusion 21 has entered the inside of the coat of the cat Ca. The protrusion 21 moves while squeezing the hair at both ends of the suction port 25 in the longitudinal direction. Therefore, of the hairs that have been separated by the two protrusions 21, the hair that has already peeled off from the body surface and the hair that is likely to peel off from the body surface are the air toward the suction port 25 between the two protrusions 21. Is efficiently guided to the suction port 25 together with the flow A2. Then, the hair is sucked into the suction air passage portion 10 from the suction port 25. That is, since the protrusions 21 are formed at both ends in the longitudinal direction of the suction port 25, the peeled hair around the protrusions 21 that is scraped off by the protrusions 21 is guided to the suction port 25. ..

As shown in FIG. 14, when the hair recovery device 100 is moved along the hair surface 90 of the cat Ca, the central portion 22a of the back peripheral peripheral portion 22 of the suction port 25 is the most convex. There is. Therefore, the central portion 22a of the rear peripheral portion 22 is closest to the body surface of the cat Ca, and the end region 22b near the protrusion 21 is located farther from the body surface of the cat Ca than the central portion 22a. The central portion 22a of the back surface side peripheral portion 22 most presses the hair on the body surface side, but the end regions 22b on both sides thereof are weaker in pressing the coat than the central portion 22a. As a result, in the region near the protrusion 21, the hair is weakly pressed and the hair is standing, so that not only the hair that the protrusion 21 directly hits but also the hair around it can be moved. can. Therefore, when the protrusion 21 separates the hair, the area of the hair that has already been peeled off from the body surface and the hair that is likely to be peeled off from the body surface increases, so that the hair can be efficiently collected. be able to.

Further, in the rear peripheral portion 22, the central portion 22a is convex in the z direction as shown in the front view shown in FIG. 5, but the end region 22b is in the center as shown in the plan view shown in FIG. It draws a curve that descends in the opposite direction in the y direction from the portion 22a. Therefore, as shown in FIG. 13, when the suction port 25 is in contact with the hair surface 90, the amount of the back surface side peripheral portion 22 pressing the hair increases from the central portion 22a toward the end region 22b. It is configured to gradually decrease. The body of the cat Ca generally has a three-dimensional curved surface that is curved in the direction along the spine and in the direction of the waist circumference of the body, but the back side peripheral portion 22 of the hair recovery device 100 has the curved surface. It is set so that it is easy to follow.

Further, in the embodiment, the shape of the protrusion 21 is formed into a substantially triangular shape when viewed from the front side, the back side, and the side surface side. However, the shape is not limited to the shape shown in the drawing, and when the suction port 25 is in contact with the hair surface 90 of the cat Ca, the front surface of the protrusion 21 becomes the hair surface 90. It suffices if it is configured so as to abut at a gentle angle. With this configuration, the protrusion 21 can give an appropriate stimulus to the cat Ca at the same time as the hair is collected, and the body of the cat Ca is not injured. Further, since the protrusions 21 are provided at both ends of the suction port 25 and the hair does not stay in the suction port 25, it is possible to suppress the inhibition of suction recovery of the hair. Further, since the protrusion 21 has a substantially triangular shape, it is possible to prevent the hair from being entangled with the protrusion 21.

The hair sucked into the suction air passage unit 10 is collected by the filter unit 42 of the hair collection unit 45. At this time, the air sucked together with the hair passes through the filter unit 42 of the hair collection unit 45, passes through the fan unit 50, and then passes through the exhaust port 55 of the fan unit 50 to the outside of the hair collection device 100. It is exhausted to. By using the exhaust port 55 in a state where it does not face the cat Ca, the exhaust does not hit the cat and does not give stress to the cat. Further, as described above, the suction port portion 20 constituting the suction air passage portion 10 can be attached to the air passage portion 30 in a positional relationship in which the front side and the back side are interchanged. Therefore, the exhaust port 55 can be used without facing the cat Ca regardless of the direction in which the cat's body is facing and the hand holding the hair recovery device 100 by the user, whether it is the right hand or the left hand.

Further, when the user moves the hair recovery device 100, the protrusion 21 simultaneously stimulates the body of the cat Ca. That is, the hair recovery device 100 makes it possible to perform an operation such as stroking the cat Ca by hand, and at the same time, recover the hair of the cat Ca without scattering it. Further, at the same time as collecting the hair of the cat Ca, the protrusion 21 stimulates the acupuncture points on the body of the cat, so that the relaxation and health of the cat Ca can be improved.

The brushing time depends on the character of the cat, but it is generally 10 minutes or less each time. In addition, the weight of the coat collected at one time is 2 g or less on average, including the molting period in which there are many coats that change. From this, it is preferable that the width between the two protrusions 21 is set between 40 mm and 50 mm, and the width of the suction port 25 is set to 15 to 20 mm in the width in the y direction. Further, the hair recovery device 100 may be configured with a diameter of the hair recovery device 100 of 15 cm or less, a total length of the hair recovery device 100 of 30 cm or less, and a volume of 170 cm ³ or less. That is, it is desirable to configure the hair recovery device 100 with a size and weight that can be held by one hand while the user recovers the hair. The surface of the air passage portion 30 constituting the suction air passage portion 10 is provided with a recessed shape 33 extending in the circumferential direction, that is, around the central axis of the suction air passage portion 10. As a result, when the user grasps the suction air passage portion 10, it is difficult to slip and it is possible to prevent the user from dropping the suction air passage portion 10. Further, by providing the recessed shape 33 on the surface, it becomes easy for the user to hold the hand regardless of the size of the hand.

Further, the suction air passage portion 10 may be made of a metal material or a resin material containing an antistatic agent. The hair recovery device 100 collects hair by moving the suction port 20 along the body of the cat. At that time, depending on the material constituting the suction air passage portion 10, it may be charged by static electricity. When the suction air passage portion 10 is charged, the discharge due to static electricity may not only stress the cat but also cause discomfort to the user. Therefore, at least a part of the suction air passage portion 10, for example, the suction port portion 20 may be made of a metal material or a resin material containing an antistatic material.

Further, according to the hair recovery device 100, the sound generated at the time of hair recovery is small, and the stress caused by the sound is not given to the cat. Therefore, even when the hair recovery device 100 is used, the cat itself can have an exchange time with the user with peace of mind.

15 and 16 are schematic views of a cross-sectional structure of a hair recovery device stand 80 on which the hair recovery device 100 according to the embodiment is placed in a used state. FIG. 15 shows a state before the hair recovery device 100 is placed on the hair recovery device stand 80, and FIG. 16 shows a state in which the hair recovery device 100 is placed.

Inside the housing 81, a filter portion 84 is arranged above the suction fan portion 83. By arranging the filter portion 84, it is possible to prevent the collected hair from entering the inside of the suction fan portion 83.

The hair recovery device 100 is inserted into the opening 82. The hair recovery device 100 is inserted with the suction port 25 side facing the suction fan portion 83 side. With this configuration, the hair accumulated in the suction air passage portion 10 of the hair recovery device 100 can be brought closer to the suction port 25 side.

As shown in FIG. 16, when the hair recovery device 100 is placed on the hair recovery device stand 80, the suction air passage portion 10 is configured to have a large opening area of the suction port 25. good. With such a configuration, the hair in the suction air passage portion 10 can be efficiently collected in the housing 81. Further, the suction fan portion 83 is arranged so as to face the fan portion 50 of the mounted hair recovery device 100, and is configured so that air flows from the opening 82 toward the suction fan portion 83 side. .. Therefore, the hair adhering to the suction air passage portion 10 can be collected in the housing 81 so as to be sucked up. For example, the suction air passage portion 10 is configured to be split in a virtual plane P, and may be configured to be split freely in a state of being placed on the hair recovery device stand 80.

Even when the hair recovery device 100 is not configured to divide the suction air passage portion 10 as shown in FIG. 16, for example, the opening area of the hair recovery device 100 can be increased by removing the suction port portion 20. By increasing the number, it becomes easier to collect the hair from the inside of the hair collecting device 100. Alternatively, the air flow by the suction fan portion 83 of the hair recovery device stand 80 may be strengthened.

The hair recovery device stand 80 may be configured so that the suction fan unit 83 is driven in conjunction with the hair recovery device 100 being mounted. With this configuration, it is not necessary to operate the power switch for driving the hair recovery device stand 80, and the hair can be easily collected from the hair recovery device 100.

The hair recovery device stand 80 has an electrode arranged at a portion in contact with the hair recovery device 100, and when the hair recovery device 100 is placed, power is supplied to the power supply unit 60 to charge the hair recovery device 60. May be equipped.

The housing 81 of the hair recovery device stand 80 may be partially made of a translucent or transparent material. With this configuration, the inside of the housing 81 can be seen through, so that the timing for removing the accumulated hair can be confirmed without opening the housing 81.
