Description

Technical Field

[0001] This utility model belongs to the field of pet comb technology, and in particular relates to a pet hair cleaning device. Background Technology

[0002] Pet hair removal is a major pain point for pet owners, especially since the hair shed by animals such as cats and dogs easily adheres to fabric surfaces (clothes / bedding / sofa), creating a breeding ground for bacteria. Even tiny hairs can trigger respiratory allergic reactions. Current solutions require first using a brush to remove the hair from the pet's body, and then cleaning up the loose hair scattered on the ground. This step-by-step process is not only cumbersome, but also difficult to collect efficiently due to the scattered nature of the hair, resulting in low cleaning efficiency.

[0003] Chinese patent application No. 202020569942.2 discloses a pet hair removal comb, including a comb body connected to the vacuum cleaner's suction tube. The comb body is provided with a comb body connecting structure and can be connected to a connecting plate through the comb body connecting structure. The connecting plate is elastically connected to a push plate. The connecting plate is provided with a brush plate. The brush plate is provided with a plurality of steel needles that penetrate the push plate. Both the connecting plate and the push plate are provided with hair removal holes and communicate with the vacuum cleaner's suction tube through the hair removal holes.

[0004] In the above technical solution, pet hair combed off can be removed from the steel needles and sucked into the vacuum cleaner through the hair suction holes and the vacuum tube. However, in the above technical solution, by making the air flow, the hair is sucked into the vacuum tube through the hair suction holes on the flow channel shell and the brush plate located in front of the flow channel shell. However, after the air flows in the flow channel shell and the hair suction holes, static electricity will inevitably be generated inside the flow channel shell and the walls of the hair suction holes. This will cause the Coulomb force generated by the static electricity to attract fine hair, making it difficult to clean all the hair in the flow channel shell and the hair suction holes into the vacuum tube. As a result, the hair will remain and adhere to the fan blades and even the entire air flow channel. Subsequently, there will be residual hair or dander falling from the hair suction holes, causing secondary environmental pollution. Moreover, the disassembly and cleaning of the equipment after use is cumbersome, which goes against the original intention of simplifying pet hair care with the hair suction comb. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a pet hair cleaning device is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A pet hair cleaning device includes a body, which includes a handheld part and a negative pressure part arranged in a relatively curved manner. The negative pressure part is provided with a negative pressure component that allows air to enter the negative pressure part from the outside of the body through a flow channel shell. An air inlet channel is provided in the negative pressure part corresponding to the axial position of the negative pressure component. The flow channel shell is provided on the negative pressure part. A storage cavity for storing pet hair or dander is formed between the flow channel shell and the opening of the air inlet channel. A barrier that can seal the storage cavity is provided at the opening of the air inlet channel. A nozzle for matching use is provided at the opening of the flow channel shell. A sealing component is provided on the nozzle.

[0008] Among them, the nozzle can be any existing long strip-shaped local nozzle that concentrates airflow; or any existing flared nozzle that can cover a large area; or a multi-functional nozzle with a comb plate and a ventilation and airflow guiding hole in the center of the comb plate that integrates hair combing and hair removal functions.

[0009] The nozzle and the opening of the flow channel shell can be detachably connected by any existing connection method, such as threaded connection, snap-fit ​​or magnetic connection; the flow channel shell and the negative pressure part can be detachably connected by any existing connection method, such as threaded connection, snap-fit ​​or magnetic connection.

[0010] When the owner uses the nozzle to vacuum up hair, the storage chamber is under negative pressure, which allows hair or dander that is easily blown away by the wind to enter the storage chamber through the nozzle. During this process, the sealing part is in the open state. After the storage chamber is full of hair or dander, the machine is stopped and the sealing part is in the closed state, thus sealing the storage chamber and preventing the collected hair or dander from falling out and causing secondary environmental pollution.

[0011] Preferably, the output shaft of the negative pressure component passes through the axial center of the negative pressure part, and the output shaft is rotatably connected to the axial end face of the negative pressure part.

[0012] By extending the output shaft of the negative pressure component into the storage cavity, it is easier to transmit the power of the negative pressure component. The rotation of the output shaft can be used to stir the axial air in the storage cavity or to provide power to the added structure located in the storage cavity.

[0013] The output shaft is equipped with a key for connecting to the mounting structure. When the output shaft rotates, the key disturbs the airflow in the storage cavity, slightly changes the angle of the axial wind, and creates a tornado effect in the storage cavity, which pulls and removes hair or dander adhering to the wall, reducing the adhesion rate of the collected material on the inner wall.

[0014] Preferably, the opening of the air inlet channel is arranged between the edge of the negative pressure section and the axis of the negative pressure section. The barrier is in the form of a ring, and the ring structure has ventilation holes that can block pet hair or dander. This prevents hair or dander from entering the negative pressure section and blocking the air inlet channel, thus reducing suction power, while ensuring the power supply to the output shaft.

[0015] Preferably, the nozzle has a guide port at the end away from the negative pressure section. The guide port extends inward or outward along the airflow direction controlled by the negative pressure component, thereby controlling the airflow direction and concentrating the airflow in the area covered by the guide port to improve the suction effect.

[0016] Preferably, the end of the flow guide that is connected to the storage cavity is provided with a sealing element.

[0017] The sealing device allows the flow port to be open when the machine is in operation, and closes when the owner turns it off, preventing hair or dander collected in the storage chamber from falling out of the flow port and causing secondary environmental pollution.

[0018] Preferably, the sealing component includes a cover plate capable of sealing the flow port and a connector for connecting the cover plate to the air nozzle, wherein the cover plate is made of an elastic material.

[0019] The cover plate and the air nozzle are connected separately using connectors, which enables the assembly of the cover plate and facilitates its replacement and maintenance.

[0020] The connecting parts can be fastening screws, rivets, or tension springs.

[0021] When the connector is a fastening screw or rivet, the specific number of connectors can be set according to actual needs, ensuring that the cover plate can be folded or deformed with the position of the connector as the folding point, so as to create a gap between the cover plate and the guide port.

[0022] When the connector is a tension spring, the tension spring can be coaxially set with the cover plate and fixed at the guide port, or it can be connected between the cover plate and the nozzle in an eccentric position.

[0023] Preferably, the connector is provided in a set and located at the side of the flow guide, so that the cover plate at the flow guide can be folded laterally, increasing the opening and closing angle between the cover plate and the flow guide.

[0024] Preferably, the cover plate includes a fixing part in an eccentric position and a sealing part that matches the diameter of the guide port. A connecting part is provided between the sealing part and the fixing part to extend the distance between them, thereby further increasing the opening and closing angle between the cover plate and the guide port by the length of the connecting part, and ensuring the sealing performance between the cover plate and the guide port.

[0025] Preferably, the connecting part has a waist-shaped hole along its own length direction, and the nozzle is provided with a fixing pin that passes through the waist-shaped hole.

[0026] The folding trajectory of the cover plate is limited by the oblong hole and the fixing pin used in conjunction with the oblong hole, so that it can return smoothly to its original position and re-close the guide port, forming a one-way check valve structure.

[0027] Preferably, the end of the nozzle away from the negative pressure section is a plane, and the nozzle is provided with a circular array of guide ports. The output shaft is poweredly connected to a blade assembly, which can trim and cut the lint balls that pass through the guide ports and enter the storage cavity.

[0028] By placing the blade assembly inside the nozzle, long hair is prevented from getting tangled, thus avoiding shaft load, motor overload, and increased motor energy consumption; it is also used as a lint trimming structure that can pick up lint balls through the guide port.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] The air nozzle and the air inlet opening are sealed to form a closed storage chamber inside the flow channel shell. When the owner turns on the machine, the guide port connects to the storage chamber. When the machine is turned off, the guide port is automatically sealed by the air nozzle, turning the storage chamber into an independent sealed compartment to collect and store hair or dander. This prevents the collected hair or dander from falling out of the guide port and causing secondary environmental pollution. After removing the air nozzle, the collected material in the storage chamber can be emptied. The owner does not need to clean the whole machine, simplifying the operation.

[0031] By collecting hair or dander in a concentrated manner by isolating it on the outside of the negative pressure component, the static electricity generated by the negative pressure component is prevented from adsorbing and adhering to it, thereby avoiding the occurrence of overload or short circuit failure of the negative pressure component caused by residual hair.

[0032] The residual kinetic energy from the rotation of the negative pressure component's output shaft is converted into functional energy, which disturbs the airflow in the storage cavity, slightly changes the angle of the axial wind, and creates a tornado effect in the storage cavity, which pulls and removes hair or dander adhering to the wall, reducing the adhesion rate of the collected material on the inner wall.

[0040] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment discloses a pet hair cleaning device, including a body 1. The body 1 includes a handheld part 2 and a negative pressure part 3 that are relatively curved. The negative pressure part 3 has a cylindrical structure. The negative pressure part 3 is provided with a negative pressure component (not shown in the figure) that allows air to enter the negative pressure part 3 from the outside of the body 1 through the flow channel shell 4. The outer circular surface of the negative pressure part 3 is fitted with a threaded flow channel shell 4. The opening of the flow channel shell 4 is provided with a matching nozzle 5. The nozzle 5 is fitted on the outer circular surface of the flow channel shell 4 and threadedly engaged with it. An air inlet channel 11 arranged in a ring is opened in the negative pressure part 3. The axial end face of the negative pressure part 3, the inner wall of the flow channel shell 4 and the axial end face of the nozzle 5 together form a storage cavity 10 that communicates with the opening of the air inlet channel 11. The storage cavity 10 is used to collect and store pet hair or dander.

[0043] The negative pressure assembly includes a fan, a fan shaft, and a power source for rotating the fan, all of which are identical to those in the prior art. The fan shaft, as the output shaft 13 of the negative pressure assembly, passes through the axial position of the negative pressure section 3. The output shaft 13, located in the storage cavity 10, is provided with a key structure (not shown in the figure) for power connection mounting. The key structure is identical to that in the prior art. The negative pressure section 3 provides rotatable support for the output shaft 13 through any existing rotary support member, thereby enabling a rotatable connection between the output shaft 13 and the axial end face of the negative pressure section 3.

[0044] The handheld part 2 is equipped with a charging component 21 that can cycle charge the power supply and a control button 22 for controlling the air volume. The charging component 21 has the same structure as any existing charging component 21 that can supply power.

[0045] A partition 12 is provided between two adjacent air inlet channels 11. The radial width of the opening of the air inlet channel 11 is between the edge position of the negative pressure part 3 and the axis position of the negative pressure part 3, and thus it is in a petal shape and closely close to the circumferential position of the outlet shaft 13.

[0046] The opening of the air inlet channel 11 is provided with a barrier (not shown in the figure) that can seal the storage cavity 10. The barrier is a filter screen with a circular structure. The filter screen has the same structure as the prior art. The filter screen has ventilation holes that can block pet hair or dander. The filter screen is glued to the surface of the negative pressure part 3 and is tightly attached to the partition 12, thereby blocking pet hair or dander from the opening of the air inlet channel 11 into the storage cavity 10.

[0047] The nozzle 5 includes two types: a collecting nozzle 51 and a brushing nozzle 52. The collecting nozzle 51 has a guide port 6 extending outward along the airflow direction controlled by the negative pressure component. This guide port 6 is the first guide port 511, which has a conical barrel-shaped structure. The tail of the first guide port 511 passes through the collecting nozzle 51 and extends into the storage cavity 10. The opening of the first guide port 511 can be a waist-shaped opening or a circular opening, which is not limited here. The collecting nozzle 51 has a vent hole 512 for increasing airflow near the axial end face of the guide port 6. The first guide port 511 is used to collect pet hair or dander. The brush nozzle 52 includes an expansion section 521 disposed on the axial end face away from the negative pressure section 3, a row of needles 522 fixedly disposed on the expansion section 521, and a guide port 6 located at the center of the expansion section 521 and extending inward along the airflow direction controlled by the negative pressure component. The expansion section 521 can increase the contact area of ​​the brush nozzle 52, thereby improving the brushing efficiency. The cross-sectional shape of the brush nozzle 52 can be circular or a racetrack shape formed by two arc-shaped sides connected by a straight line in the middle. The guide port 6 is a second guide port 523. The second guide port 523 is used by the owner to absorb the hair or dander that has fallen off the pet while grooming the pet.

[0048] The end of the first flow port 511 or the second flow port 523 connected to the storage cavity 10 is provided with a mounting base 53 for installing the sealing component. The mounting base 53 is located in a lateral position of the first flow port 511 or the second flow port 523. The sealing component includes a cover plate 54 that can cover the flow port 6 and a connector 55 for connecting the cover plate 54 to the nozzle 5. The cover plate 54 is made of elastic material. The cover plate 54 includes a fixing part 543 in an eccentric position and a sealing part 541 that matches the diameter of the flow port 6. A connecting part 542 that can extend the distance between the sealing part 541 and the fixing part 543 is provided. The connector 55 is located in a lateral position of the flow port 6. The connector 55 passes through the fixing part 543 and is connected to the mounting base 53. The connector 55 is a fixing screw.

[0049] The connecting part 542 has a waist-shaped hole 544 along its own length direction. The nozzle 5 has a fixing pin 6 that passes through the waist-shaped hole 544, thereby limiting the folding trajectory of the cover part 541 and enabling it to return smoothly to its original position, re-closing the first guide port 511 or the second guide port 523, forming a one-way check valve structure.

[0050] When the fan starts, it creates a negative pressure area inside the storage cavity 10. The flowing air causes the cover 541 to fold inward, thereby opening the first guide port 511 or the second guide port 523. Air enters the storage cavity 10 through the first guide port 511 or the second guide port 523 and flows away along the air inlet channel 11. During this process, the barrier separates pet hair or dander from the flowing air, thereby collecting and storing the pet hair or dander in the storage cavity 10.

[0051] Example 2

[0052] The difference between this embodiment and Embodiment 1 is that: the nozzle 5 is a flat end cap 71, which is threadedly connected to the outer surface of the flow channel shell 4 via a connecting sleeve. The nozzle 5 is provided with a ring array of guide ports 6, which are the third guide ports 711. The third guide ports 711 can be used as de-hairing holes for lint balls to enter the storage cavity 10. The output shaft 13 is poweredly connected to the blade assembly 72 via a key structure. The blade assembly 72 has the same structure as any existing cutting assembly capable of cutting lint balls. The blade assembly 72 can trim and cut the lint balls that pass through the third guide port 711 and enter the storage cavity 10.

[0053] When the owner needs to trim or cut the lint, the blade assembly 72 is installed on the output shaft 13 and the flat end cap 71 is fastened. Force is applied to the hand handle 2 and the flat end cap 71 is pressed tightly against the lint. The lint is then pressed and enters the storage chamber 10 through the third guide port 711, where it is trimmed or cut by the blade assembly 72. At this time, the lint is collected in the storage chamber 10 under the action of the air inlet channel 11. The grooming is completed after the owner finishes trimming.
