Description

Technical Field

[0001] This invention relates to the field of pet care device technology, and more specifically to a pet hair brush and a pet vacuum cleaner. Background Technology

[0002] Most pet grooming combs currently in use consist of a handle and a comb head attached to the handle. The comb head has bristles that are used to comb the pet's fur. During combing, pet hair easily falls to the ground or gets tangled in the bristles. This loose hair needs to be manually removed by the user, which is not only time-consuming and laborious but also easily leaves hair behind, affecting hygiene. Therefore, a technical solution has been proposed that can both comb pet hair and remove it.

[0003] For example, utility model patent CN215736369U discloses a pet comb that facilitates hair removal. The comb body includes a head, a handle, a push plate assembly, a base plate, and a self-locking mechanism. The head has a suction chamber and a push plate chamber. The top of the push plate chamber has an installation port, and the handle has a suction channel. The push plate assembly is located between the push plate chamber and the base plate and includes a push plate with combing needles, a connecting bracket, a button, and a spring. The base plate has a suction port and a through hole. The self-locking mechanism locks or unlocks the push plate assembly by pressing. In this technical solution, the combing needles, when locked and extending outside the base plate, facilitate combing of pet hair. During combing, the suction device is used to remove loose hair through the suction port, allowing for timely cleaning during combing. Furthermore, this technical solution has a pressure relief hole at the top of the suction chamber. The pressure relief hole can be blocked by pressing down on the push plate assembly. The pressure relief hole can effectively reduce the suction force of the suction port, thereby preventing the suction force of the suction port from being too strong and directly adhering to the pet's skin, making it difficult to groom the fur. However, the sealing and opening of this pressure relief hole requires the user to press a button, which is difficult for the user to operate with one hand. In actual use, it is not only laborious but also easy for the user to forget. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pet hair removal comb that automatically extends its comb teeth and opens a pressure relief hole by abutting against the surface being combed, and retracts its comb teeth and closes the pressure relief hole by disengaging from the surface being combed, so that the comb teeth and pressure relief hole can be opened and closed in conjunction without any additional operation by the user.

[0005] This invention provides a pet hair removal comb, including a handle and an air inlet channel. A comb tooth plate is mounted on the handle. The comb is characterized by further including a rotating hair removal part with an opening adapted to the comb tooth plate. When the rotating hair removal part rotates around the handle, the comb tooth plate extends and retracts through the opening. A pressure relief channel communicating with the air inlet channel is provided between the handle and the rotating hair removal part. The pressure relief channel has a pressure relief port as an outlet. The rotating hair removal part is provided with a sealing structure for opening and closing the pressure relief channel. When the rotating hair removal part is subjected to force and rotates backward around the handle, the sealing structure rotates backward to open the pressure relief channel. When the rotating hair removal part rotates forward around the handle to reset, the pressure relief channel closes.

[0006] In this technical solution, the rotating hair removal part is rotatably connected to the handle. A comb plate is installed on the handle, and an opening adapted to the comb plate is provided on the rotating hair removal part. When the user holds the handle, the front end of the rotating hair removal part is in contact with the surface being combed, including the surface of the pet's fur. The user applies pressure to the handle, causing the surface being combed to exert a reverse supporting force on the rotating hair removal part, thus allowing the rotating hair removal part to rotate backward around the handle. The opening on the rotating hair removal part rotates backward synchronously with the rotating hair removal part, at which point the comb plate gradually passes through the opening and is exposed. The user can comb the pet's fur through the exposed comb teeth. During the movement of the handle, the front end of the rotating hair removal part is always in contact with the surface being combed, that is, the comb teeth are always in the extended state. When the rotating hair removal part is separated from the surface being combed, the rotating hair removal part is not under force and can rotate forward around the handle to reset. The opening rotates forward synchronously with the rotating hair removal part, causing the comb teeth to retract into the opening. During the forward rotation, the front end of the opening is close to the bottom of the comb teeth, which can push out the hair wrapped on the comb teeth, thus achieving automatic hair removal.

[0007] An air inlet channel is provided on the handle, allowing the combed hair to be sucked away for automatic hair removal. A pressure relief channel connected to the air inlet channel is also provided on the handle, allowing gas to enter the air inlet channel through the pressure relief port. A sealing structure for opening and closing the pressure relief channel is provided on the rotating hair removal part, ensuring the channel is closed under normal conditions. When the front end of the rotating hair removal part is in contact with the surface being combed, and the part rotates backward around the handle, the sealing structure rotates backward synchronously, opening the pressure relief channel. This effectively reduces the negative pressure within the air inlet channel, preventing the hair-collecting comb from directly adhering to the surface due to excessive suction during combing. On the surface, excessive suction can easily cause discomfort to pets, and excessive suction can also affect the movement of the hair removal comb, affecting combing efficiency. When the front end of the rotating hair removal part disengages from the combed surface, the rotating hair removal part can rotate forward around the handle to reset. The sealing structure rotates forward synchronously with the rotating hair removal part to close the pressure relief channel, and the opening can automatically push the hair on the comb teeth plate through rotation. The extension of the comb teeth plate and the opening of the pressure relief channel are both achieved synchronously by rotating the rotating hair removal part against the combed surface. The retraction of the comb teeth plate and the closing of the pressure relief channel are both achieved synchronously by rotating the rotating hair removal part to reset. Users can achieve the linkage opening and closing of the comb teeth plate and the pressure relief channel without any additional operation, and it can be operated with one hand, making it labor-saving and convenient to use.

[0008] As an improvement, the rotating dehairing part and the handle part are connected by a sleeve to form a pressure relief channel that connects to the pressure relief port.

[0009] In this technical solution, the rotating hair removal part and the handle part are rotated and sleeved. The cavity of the sleeved part of the rotating hair removal part and the handle part forms a pressure relief channel that can be connected to the pressure relief port. This makes the pressure relief channel hidden inside the hair removal comb. The hidden pressure relief channel is ingeniously designed and it is not easy for foreign objects to enter and block the pressure relief channel.

[0010] As an improvement, a first inlet connected to a pressure relief channel is formed between the rear end of the rear sidewall of the rotating hair removal part and the rear sidewall of the handle part. The rotating hair removal part rotates backward around the handle part to open the first inlet, and the rotating hair removal part rotates forward around the handle part to reset and close the first inlet.

[0011] In this technical solution, the rotating hair removal part and the handle part are connected in a sleeve structure. The air inlet of the air inlet channel is located at the front end of the handle part, so that the hair combed off by the comb teeth can be directly drawn into the air inlet channel through the front air inlet. A first inlet connected to the pressure relief channel is formed between the rear end of the rear side wall of the rotating hair removal part and the rear side wall of the handle part. The first inlet is set opposite to the air inlet, which improves the pressure relief efficiency. Furthermore, by setting the first inlet at the sleeve gap between the rotating hair removal part and the handle part, the first inlet opens and closes with the rotation of the rotating hair removal part. When the front end of the rotating hair removal part is in contact with the surface being combed, the rotating hair removal part rotates backward around the handle part to open the first inlet, allowing external air to enter the pressure relief channel through the first inlet. When the front end of the rotating hair removal part disengages from the combed surface, the rotating hair removal part can rotate forward around the handle to reset and close the first inlet. The opening and closing of the first inlet is automatically achieved with the rotation of the rotating hair removal part, without the need for user operation. On the other hand, the closer the rotating hair removal part is to the combed surface, the greater the reverse force on the rotating hair removal part, and the greater the angle of rotation of the rotating hair removal part relative to the handle. Then, the opening degree of the first inlet is also greater, and the pressure relief effect of the air intake channel is better. This avoids the air inlet being too close to the combed surface, which would cause excessive suction and discomfort to the pet. Therefore, the structural design of this first inlet makes the pressure relief effect of the air intake channel automatically adjusted with the rotation of the rotating hair removal part, without the need for user operation, making it labor-saving and convenient to use.

[0012] As an improvement, a stopper is installed on the front side of the rotating hair removal part, and the rotating hair removal part rotates by abutting against the combed surface through the stopper.

[0013] In this technical solution, by setting a stopper on the front side of the rotating hair removal part, the user holds the handle and makes the stopper fit against the surface to be combed. This not only makes the pet more comfortable and less resistant to hair combing, but also increases the contact area with the surface to be combed, making the rotating hair removal part more flexible in rotation. Considering that the pet's surface is not smooth and has undulations, the stopper is set to improve the rotation efficiency of the rotating hair removal part, so that the rotating hair removal part can automatically rotate and fit the surface of the pet with different heights, making the combing efficiency higher and requiring no user adjustment, thus saving effort.

[0014] As an improvement, a first elastic reset member is provided between the rotating dehairing part and the handle part. One end of the first elastic reset member is connected to the rotating dehairing part, and the other end of the first elastic reset member is connected to the handle part. The rotating dehairing part is rotated and reset by the first elastic reset member.

[0015] In this technical solution, a first elastic reset member is provided between the rotating de-hairing part and the handle part. The front end of the rotating de-hairing part rotates backward by abutting against the combed surface. At this time, the first elastic reset member is compressed by the pressure of the rotating de-hairing part, and the rotating de-hairing part is always in contact with the combed surface due to the forward elastic force of the first elastic reset member. When the front end of the rotating de-hairing part is separated from the combed surface, the rotating de-hairing part is not subject to the relative force of the combed surface. Under the action of the first elastic reset member, the rotating de-hairing part rotates forward to reset. By setting the first elastic reset member, the user only needs to separate the front end of the rotating de-hairing part from the combed surface to make the comb tooth plate retract and the pressure relief channel close, without the need for additional operation control, making it labor-saving and convenient for the user.

[0016] As an improvement, the sealing structure is adapted to the pressure relief port, and the sealing structure opens and closes the pressure relief port by rotation.

[0017] In this technical solution, the sealing structure can be set up in three ways to block the pressure relief channel: the sealing structure is set at the first inlet, the sealing structure is set inside the pressure relief channel, or the sealing structure is set at the pressure relief port. It is preferable to set the sealing structure at the pressure relief port, which can prevent the combed hair from entering the pressure relief channel through the pressure relief port and blocking the pressure relief channel. The sealing structure is adapted to the pressure relief port, and the sealing structure opens and closes the pressure relief port as the hair removal part rotates, which is labor-saving.

[0018] As an improvement, the pressure relief port is located at the end of the handle near the rotating de-hairing part, and the surface of the end of the handle near the rotating de-hairing part is arc-shaped. In this technical solution, the pressure relief port is located near the rotating de-hairing part to facilitate the installation of a sealing structure adapted to the pressure relief port in the rotating de-hairing part, resulting in a simple structural design.

[0019] As an improvement, a plurality of reinforcing ribs are provided between the opening and the inner wall of the rotating de-hairing part. The bottom surface of the reinforcing ribs is arc-shaped and fits against the top surface of the handle. In this technical solution, the structural stability of the rotating de-hairing part can be increased by providing reinforcing ribs, and the arc-shaped bottom surface of the reinforcing ribs ensures that the rotating de-hairing part is not interfered with by the reinforcing ribs when rotating relative to the handle, thereby improving the rotation efficiency.

[0020] As an improvement, the reinforcing ribs are positioned to avoid the pressure relief port and are located on both sides of the pressure relief port, and the sealing structure is the cavity between the reinforcing ribs on both sides of the pressure relief port.

[0021] In this technical solution, the sealing structure consists of two adjacent reinforcing ribs located on both sides of the pressure relief port. The bottom surface of the reinforcing ribs is in contact with the top surface of the handle, and the cavity formed between the two adjacent reinforcing ribs can just seal the pressure relief port. When the front end of the rotating de-hair part is pressed against the combed surface and rotates backward, the reinforcing ribs also rotate backward synchronously with the rotating de-hair part. At this time, the arc-shaped bottom surface of the reinforcing ribs cannot be completely in contact with the top surface of the handle, and there is a gap between the bottom surface of the reinforcing ribs and the top surface of the handle, thus opening the pressure relief port. When the front end of the rotating de-hair part is separated from the combed surface and the rotating de-hair part rotates forward to reset, the reinforcing ribs also rotate forward synchronously with the rotating de-hair part. The arc-shaped bottom surface of the reinforcing ribs is completely in contact with the top surface of the handle, thus sealing the pressure relief port. The sealing structure formed by the two adjacent reinforcing ribs eliminates the need for other structures to seal the pressure relief port of the rotating de-hair part. The ingenious structural design simplifies the manufacturing process.

[0022] The present invention can also provide a pet vacuum cleaner, including the aforementioned pet hair comb, and a vacuum cleaner body, wherein the handle is detachably connected to the vacuum cleaner body, and the handle is connected to the vacuum cleaner body through an air inlet channel.

[0023] In this technical solution, the pet hair comb is an accessory of the pet vacuum cleaner. The vacuum cleaner body is detachably connected to the handle of the hair comb via a flexible hose. After the vacuum cleaner body and the hair comb are connected, the air inlet channel is connected to the vacuum cleaner body. Under the action of the motor, the hair can be sequentially drawn from the air inlet and the air inlet channel into the vacuum cleaner body, so that the hair can be cleaned in time during combing, improving the convenience of use.

[0024] This invention describes a pet hair-removing comb and a pet vacuum cleaner. The comb includes a handle and a rotating hair-removing part connected rotatably. A comb tooth plate is installed on the handle, and an opening adapted to the comb tooth plate is provided on the rotating hair-removing part. A pressure relief channel communicating with an air inlet channel is provided between the handle and the rotating hair-removing part. The rotating hair-removing part is provided with a sealing structure. By the front end of the rotating hair-removing part abutting against the surface being combed, the rotating hair-removing part rotates backward relative to the handle. The opening and the sealing structure rotate backward synchronously with the rotating hair-removing part, causing the comb tooth plate to extend relative to the opening and the pressure relief channel to open. By the front end of the rotating hair-removing part disengaging from the surface being combed, the rotating hair-removing part rotates forward relative to the handle to reset. The opening and the sealing structure rotate forward synchronously with the rotating hair-removing part, causing the comb tooth plate to retract relative to the opening and the pressure relief channel to close. The user can achieve the linkage opening and closing of the comb tooth plate and the pressure relief channel without any additional operation, making it labor-saving and convenient to use.

[0039] Example 1

[0040] like Figures 1 to 10 As shown, this application discloses a pet grooming comb, including a handle part 1 and a rotating grooming part 2. The rotating grooming part 2 has connecting arms 21 on both sides that are adapted to the handle part 1. Each connecting arm 21 has a rotating protrusion 211 with a buckle 212. The handle part 1 has connecting holes 11 on both sides that are adapted to the connecting arms 21. Each connecting hole 11 has a groove 111 adapted to the buckle 212. The rotating protrusion 211 is inserted into the connecting hole 11, causing the buckle 212 to engage with the groove 111. The buckle 212 and the groove 111 engage to rotate the rotating grooming part 2 onto the handle part 1. The groove 111 controls the rotation range of the rotating grooming part 2, preventing excessive rotation and ensuring efficient grooming. The buckle structure is simple and reliable.

[0041] like Figures 1 to 3 As shown, a comb plate 3 is mounted on the handle 1. The comb plate 3 is fixed to the upper end of the handle 1 by bolts. The rotating hair removal part 2 exposes or hides the comb plate 3 by rotating around the handle 1. The front end of the rotating hair removal part 2 is provided with an opening 22 that matches the comb plate 3. When the user holds the handle 1, the front end of the rotating hair removal part 2 is in contact with the surface being combed, including the surface of the pet's fur. The user applies pressure to the handle 1, which causes the surface being combed to exert a reverse supporting force on the rotating hair removal part 2. Figure 6 As shown, the rotating dehair removal part 2 can therefore rotate backward around the handle part 1. The opening 22 on the rotating dehair removal part 2 rotates backward synchronously with the rotating dehair removal part 2. At this time, the comb plate 3 gradually passes through the opening 22 and is exposed. The user can comb the pet's fur through the exposed comb plate 3. During the movement of the handle part 1, the front end of the rotating dehair removal part 2 is always in contact with the surface being combed, that is, the comb plate 3 is always in the extended state. When the rotating dehair removal part 2 is separated from the surface being combed, the rotating dehair removal part 2 is not under force, such as Figure 1 As shown, the rotating hair removal part 2 can rotate forward around the handle part 1 to reset. The opening 22 rotates forward synchronously with the rotating hair removal part 2, causing the comb plate 3 to retract into the opening 22. During the forward rotation, the front end of the opening 22 is close to the bottom of the comb plate 3, which can push out the hair wrapped on the comb plate 3, thus realizing automatic hair removal.

[0042] like Figure 4As shown, the handle 1 is provided with an air inlet 12 and an air inlet channel 13. The air inlet 12 is connected to the air inlet channel 13, and the hair that is combed out can be sucked into the air inlet channel 13 through the air inlet 12 to achieve the purpose of automatic hair removal. A pressure relief channel connected to the air inlet channel 13 is provided between the handle 1 and the rotating hair removal part 2. The sealing structure 23 is used to open and close the pressure relief channel, so that the pressure relief channel is in the closed state under normal conditions. The front end of the rotating hair removal part 2 is in contact with the surface being combed, such as... Figure 7 and Figure 8 As shown, the rotating hair removal part 2 rotates backward around the handle part 1, causing the sealing structure 23 to rotate backward synchronously with the rotating hair removal part 2, thus opening the pressure relief channel. This pressure relief channel effectively reduces the negative pressure within the air inlet channel 13, preventing the hair removal comb from directly adhering to the surface being combed due to excessive suction at the air inlet 12, which could easily cause discomfort to the pet. Excessive suction also affects the movement of the hair removal comb, impacting combing efficiency. When the front end of the rotating hair removal part 2 disengages from the surface being combed, the rotating hair removal part 2 can rotate forward around the handle part 1. The reset and sealing structure 23 rotates forward synchronously with the rotating hair removal part 2, causing the pressure relief channel to close. The opening 22 can automatically push the hair on the comb plate 3 out by rotating. The extension of the comb plate 3 and the opening of the pressure relief channel are both achieved synchronously by rotating the hair removal part 2 against the combed surface. The retraction of the comb plate 3 and the closing of the pressure relief channel are both achieved synchronously by rotating the hair removal part 2 to reset. The user can achieve the linkage opening and closing of the comb plate 3 and the pressure relief channel without any additional operation. Moreover, it can be operated with one hand, making it labor-saving and convenient to use.

[0043] The rotating depilatory part 2 and the handle part 1 are rotatably connected. The connecting part between the lower end of the rotating depilatory part 2 and the upper end of the handle part 1 has a cavity. This cavity is connected to the pressure relief port 14 to form a pressure relief channel. Gas enters the air inlet channel 13 through the pressure relief channel to the pressure relief port 14 to achieve the purpose of pressure relief. The pressure relief channel is located in the connecting part between the rotating depilatory part 2 and the handle part 1, forming a hidden pressure relief channel structure. The design is ingenious and it is not easy for foreign objects to enter and block the pressure relief channel.

[0044] like Figure 5 , Figure 8 and Figure 10As shown, a first inlet 5, which connects to a pressure relief channel, is formed between the rear end of the rear sidewall 25 of the rotating de-hairing part and the rear sidewall 15 of the handle part. The first inlet 5 is arranged opposite to the air inlet 12, resulting in higher pressure relief efficiency. By positioning the first inlet 5 at the sleeve gap between the rotating de-hairing part 2 and the handle part 1, the first inlet 5 opens and closes as the rotating de-hairing part 2 rotates. When the front end of the rotating de-hairing part 2 is in contact with the combed surface, the rotating de-hairing part 2 rotates backward around the handle part 1 to open the first inlet 5, allowing external air to enter the pressure relief channel through the first inlet 5. When the front end of the rotating de-hairing part 2 disengages from the combed surface, the rotating de-hairing part 2 can rotate backward around the handle part 1 to open the first inlet 5. The front rotation reset closes the first inlet 5. The opening and closing of the first inlet 5 is automatically achieved with the rotation of the rotating hair removal part 2, without the need for user operation. On the other hand, the closer the rotating hair removal part 2 is to the surface being combed, the greater the reverse force on the rotating hair removal part 2. The greater the angle of rotation of the rotating hair removal part 2 relative to the handle part 1, the greater the opening degree of the first inlet 5. The better the pressure relief effect of the air intake channel, the better it is. This avoids the air inlet being too close to the surface being combed, which would cause excessive suction and make the pet uncomfortable. Therefore, the structural design of the first inlet 5 makes the pressure relief effect of the air intake channel 13 automatically adjusted with the rotation of the rotating hair removal part 2, without the need for user operation, making it labor-saving and convenient to use.

[0045] like Figure 10 As shown, a retaining member 6 is installed on the front side of the rotating hair removal part 2. The rotating hair removal part 2 rotates by abutting against the surface to be combed through the retaining member 6. The surface of the retaining member 6 is provided with several massage protrusions, which are strip-shaped and evenly distributed. When the user holds the handle part 1, the retaining member 6 is pressed against the surface to be combed. This not only makes the pet more comfortable and less resistant to hair combing, but also increases the contact area with the surface to be combed, making the rotating hair removal part 2 more flexible in rotating under force. Considering that the pet's surface is not a smooth surface and has undulations, the retaining member 6 is set to improve the rotation efficiency of the rotating hair removal part 2, so that the rotating hair removal part 2 can automatically rotate and fit the surface of the pet with different heights, making the combing efficiency higher and requiring no adjustment by the user, saving effort.

[0046] like Figure 2 and Figure 3As shown, a first elastic reset member 4 is provided between the rotating de-hair removal part 2 and the handle part 1. One end of the first elastic reset member 4 is connected to the rotating de-hair removal part 2, and the other end is connected to the handle part 1. The front end of the rotating de-hair removal part 2 rotates backward by abutting against the combed surface. At this time, the first elastic reset member 4 is compressed by the pressure of the rotating de-hair removal part 2, and the rotating de-hair removal part 2 is always in contact with the combed surface due to the forward elastic force of the first elastic reset member 4. When the front end of the rotating de-hair removal part 2 is separated from the combed surface, the rotating de-hair removal part 2 is not subject to the relative force of the combed surface. Under the action of the first elastic reset member 4, the rotating de-hair removal part 2 rotates forward to reset. By setting the first elastic reset member 4, the user only needs to separate the front end of the rotating de-hair removal part 2 from the combed surface to retract the comb plate 3 and close the pressure relief channel without additional operation control, making it labor-saving and convenient for the user.

[0047] There are three ways to block the pressure relief channel using the sealing structure 23: the sealing structure 23 is set at the first inlet 5, the sealing structure 23 is set inside the pressure relief channel, or the sealing structure 23 is set at the pressure relief port 14. All three methods can be implemented. In this embodiment, the sealing structure 23 is set at the pressure relief port 14, which can prevent the combed hair from entering the pressure relief channel through the pressure relief port 14 and blocking the pressure relief channel. The sealing structure 23 is adapted to the pressure relief port 14. The sealing structure 23 rotates with the rotating hair removal part 2 to open and close the pressure relief port 14, which is labor-saving.

[0048] like Figure 4 As shown, the pressure relief port 14 is located at the end of the handle 1 near the rotating hair removal part 2. The surface of the end of the handle 1 near the rotating hair removal part 2 is arc-shaped to facilitate the installation of a sealing structure 23 adapted to the pressure relief port 14 on the rotating hair removal part 2. The structure design is simple. The air inlet 12 is located at the end of the handle 1 near the rotating hair removal part 2. The air inlet 12 is located on the front side of the air inlet channel 13, and the pressure relief port 14 is located on the top of the air inlet channel 13. The air inlet 12 is located on the front side of the air inlet channel 13 so that when the front end of the rotating hair removal part 2 abuts against the combed surface, the hair combed off by the comb tooth plate 3 can be directly sucked into the air inlet channel 13 through the front air inlet 12. The pressure relief port 14 is located on the top of the air inlet channel 13 so that the pressure relief port 14 is close to the air inlet 12, which avoids the air inlet 12 having excessive suction and directly adhering to the combed surface, which is beneficial to improving the hair removal efficiency.

[0049] More specifically, such as Figure 2 As shown, a number of reinforcing ribs 24 are provided between the opening 22 and the inner wall of the rotating de-hairing part 2. The structural stability of the rotating de-hairing part 2 is increased by providing the reinforcing ribs 24. The bottom surface of the reinforcing ribs 24 is arc-shaped and fits against the top surface of the handle part 1. By providing the bottom surface of the reinforcing ribs 24 to be arc-shaped, the rotating de-hairing part 2 will not be interfered with by the reinforcing ribs 24 when rotating relative to the handle part 1, thereby improving the rotation efficiency.

[0050] More specifically, such as Figure 2 and Figure 5 As shown, the reinforcing ribs 24 are positioned on both sides of the pressure relief port 14, avoiding it. The sealing structure 23 is the cavity between the reinforcing ribs 24 on both sides of the pressure relief port 14. The sealing structure 23 is composed of two adjacent reinforcing ribs 24, which are located on both sides of the pressure relief port 14. The bottom surface of the reinforcing ribs 24 is in contact with the top surface of the handle part 1. The cavity formed between the two adjacent reinforcing ribs 24 can just seal the pressure relief port 14. When the front end of the rotating hair removal part 2 is pressed against the combed surface and rotates backward, the reinforcing ribs 24 also rotate backward synchronously with the rotating hair removal part 2. Therefore, the arc-shaped bottom surface of the reinforcing ribs 24 cannot be completely in contact with the top surface of the handle part 1. Figure 8 As shown, there is a gap between the bottom surface of the reinforcing rib 24 and the top surface of the handle part 1, which allows the pressure relief port 14 to open. When the front end of the rotating de-hair part 2 is separated from the combed surface and the rotating de-hair part 2 rotates forward to reset, the reinforcing rib 24 also rotates forward synchronously with the rotating de-hair part 2. The arc-shaped bottom surface of the reinforcing rib 24 is completely attached to the top surface of the handle part 1, so that the pressure relief port 14 is closed. The two adjacent reinforcing ribs 24 form a sealing structure 23, so that the rotating de-hair part 2 does not need to set other structures to seal the pressure relief port 14. The structure design is ingenious and simplifies the production and processing difficulty.

[0051] Example 2

[0052] This embodiment provides a pet vacuum cleaner based on Embodiment 1, including a pet hair comb as described in Embodiment 1, and a vacuum cleaner body. The pet hair comb is an accessory of the pet vacuum cleaner. The vacuum cleaner body is detachably connected to the handle 1 of the hair comb via a hose. After the vacuum cleaner body and the hair comb are connected, the air inlet channel 13 is connected to the vacuum cleaner body. Under the action of the motor, the hair can be sequentially drawn from the air inlet 12 and the air inlet channel 13 into the vacuum cleaner body, thereby enabling timely cleaning of the hair during combing and improving ease of use.

[0053] This specific embodiment describes a pet hair-removing comb and a pet vacuum cleaner. The comb includes a handle portion 1 and a rotating hair-removing portion 2, which are rotatably connected. A comb tooth plate 3 is installed on the handle portion 1, and an opening 22 adapted to the comb tooth plate 3 is provided on the rotating hair-removing portion 2. A pressure relief channel communicating with an air inlet channel 13 is provided between the handle portion 1 and the rotating hair-removing portion 2. The rotating hair-removing portion 2 is provided with a sealing structure 23. By the front end of the rotating hair-removing portion 2 abutting against the surface being combed, the rotating hair-removing portion 2 rotates backward relative to the handle portion 1. Both the 2 and the sealing structure 23 rotate backward synchronously with the rotating hair removal part 2, causing the comb plate 3 to extend relative to the opening 22 and the pressure relief channel to open. By disengaging the front end of the rotating hair removal part 2 from the combed surface, the rotating hair removal part 2 rotates forward relative to the handle part 1 to reset. Both the opening 22 and the sealing structure 23 rotate forward synchronously with the rotating hair removal part 2, causing the comb plate 3 to retract relative to the opening 22 and the pressure relief channel to close. The user can achieve the linkage opening and closing of the comb plate 3 and the pressure relief channel without any additional operation, making it labor-saving and convenient to use.

[0054] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
