Description

Technical Field

[0001] This utility model relates to the field of hair suction technology, and in particular to a hair suction head and a hair suction device. Background Technology

[0002] A pet hair vacuum cleaner typically consists of a suction head, main body, suction adjustment device, filter, motor, and power supply. It works by using the negative pressure effect generated by the motor to draw in air, pet hair, dust, and other impurities through the suction head, then separating the pet hair and dust from the air through the filter. It has a compact structure, is easy to operate, and can efficiently clean pet hair and dust.

[0003] There are many pet hair vacuum cleaner heads on the market, typically consisting of a hollow cylindrical shell and comb teeth. The comb teeth are made of a hard material, usually a metal comb. When the vacuum head comes into contact with the pet's fur, the comb teeth can straighten the fur, ensuring that the suction can better pick up the fur and prevent pet hair from flying around. However, exposed comb teeth pose a safety risk, and the extension length of the comb teeth cannot be freely adjusted and locked to adapt to different pets' fur lengths and densities. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a hair vacuum cleaner head and a hair vacuum cleaner, which allows adjustment of the length of the comb teeth extending out of the air inlet plane via an adjusting component, and can be locked by a locking component, thereby improving the safety and ease of use of the hair vacuum cleaner head. It is a vacuum cleaner head with adjustable settings, which locks the extension length of the comb teeth to zero when the head is not in use to avoid scratches, and also allows for precise control of the extension length of the comb teeth.

[0005] This utility model provides a hair removal tool head, including a housing, a brush head assembly, and a locking assembly;

[0006] The housing is provided with an air intake channel, and the housing is provided with an air inlet that communicates with the air intake channel.

[0007] The brush head assembly includes an adjusting member and comb teeth. The adjusting member is slidably mounted on the housing. The comb teeth are fixedly connected to the adjusting member and arranged parallel to the air intake direction of the air inlet. The adjusting member is used to adjust the length of the comb teeth extending out of the air inlet plane.

[0008] The locking assembly includes a locking groove and a push button. The locking groove is formed on the adjusting member, and the push button is slidably mounted on the housing. The push button is used to slide into the locking groove to lock the position of the adjusting member.

[0009] Specifically, the locking groove includes a first locking groove segment and a second locking groove segment, which are arranged sequentially back and forth along the sliding direction of the adjusting member to lock the length of the comb teeth extending out of the air inlet plane.

[0010] Specifically, the inner side of the adjusting member is provided with a sliding protrusion, and the outer side of the housing is provided with a slide rail. The sliding protrusion and the slide rail are used to cooperate with each other to guide the adjusting member to slide on the housing. The direction of the slide rail is consistent with the length direction of the comb teeth.

[0011] Specifically, the opening direction of the locking groove is perpendicular to the length direction of the comb teeth, and the housing also includes a limiting stop block for limiting the sliding direction of the push knob to be parallel to the opening direction of the locking groove.

[0012] Specifically, the hair removal head also includes an elastic reset member. The adjusting member has a cavity for accommodating the elastic reset member. One end of the elastic reset member is fixedly connected to the adjusting member, and the other end is fixedly connected to the housing.

[0013] Specifically, the elastic reset member is a tension spring, which provides a preload to bring the adjusting member closer to the air inlet to keep the comb teeth extending out of the air inlet plane.

[0014] Specifically, the elastic reset element is a spring, which provides a preload to move the adjusting element away from the air inlet to limit the length of the comb teeth extending out of the air inlet plane.

[0015] Specifically, the hair suction head also includes a connecting assembly, which includes a fixing member and an insert member. The fixing member is fixedly disposed on the housing, and the insert member is used to insert into the fixing member to connect the suction channel and the insert member.

[0016] Specifically, the inner wall of the fastener is provided with an insertion groove and a rotation groove that are interconnected. The insertion groove and the rotation groove are parallel and the groove direction is consistent with the insertion direction of the insert. The outer wall of the insert is provided with an insertion protrusion, which is slidably accommodated in the insertion groove or the rotation groove.

[0017] This utility model also provides a hair suction device, including an air tube and a hair suction head as described in any of the above claims, wherein the air tube is connected to the air suction channel.

[0018] In summary, this utility model embodiment adjusts the length of the comb teeth extending beyond the air inlet plane using an adjusting component, and can be locked using a locking assembly, thus improving the safety and ease of use of the hair suction head. It is a suction head with adjustable settings, locking the comb teeth extension length to zero when the suction head is not in use to prevent scratches, and also allowing for precise control of the comb teeth extension length.

[0019] Furthermore, the design of multiple locking slots at different distances, combined with the push-twist controllable adjustment mechanism, locks the comb teeth in different positions to control their extension length.

[0020] Furthermore, the adjusting component also has a cavity for accommodating the elastic reset component. One end of the elastic reset component is fixedly connected to the adjusting component, and the other end is fixedly connected to the housing. If the elastic reset component is a tension spring, the tension spring provides preload to keep the adjusting component close to the air inlet in the default state, thus maintaining the comb teeth extending beyond the air inlet plane. In the default state, pushing the knob away from the locking slot allows the comb teeth to extend beyond the air inlet plane, and the suction head can be picked up for use, improving efficiency. Even when the knob is pushed away from the locking slot, the adjusting component can still be pushed or pulled to temporarily control the length of the comb teeth extending beyond the air inlet plane. After releasing the knob, the comb teeth extend beyond the air inlet plane under the action of the tension spring.

[0021] Furthermore, if the elastic reset element is a spring, the spring provides preload to keep the adjusting element away from the air inlet, thus limiting the length of the comb teeth extending beyond the air inlet plane. In the default state, pushing the knob away from the locking slot moves the comb teeth away from the air inlet plane. Depending on the spring preload, the comb teeth may not extend beyond the air inlet plane, improving the safety of the suction head. Even with the knob pushed away from the locking slot, the adjusting element can still be pushed or pulled to temporarily control the length of the comb teeth extending beyond the air inlet plane. After releasing the knob, the comb teeth will not extend beyond the air inlet plane due to the tension spring.

[0022] Furthermore, the hair vacuum cleaner head also includes a connecting component, which includes a fixing part and an insert part. The fixing part is fixedly mounted on the housing, and the insert part is fixedly connected to the air tube of the hair vacuum cleaner. Both the insert part and the fixing part are standard parts, and it is only necessary to disassemble and assemble them when changing to different styles of vacuum cleaner heads, which improves the replacement efficiency.

[0046] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0047] The following detailed description uses specific examples.

[0048] like Figures 1 to 4 As shown, this utility model embodiment provides a hair suction head, including a housing 100, a brush head assembly 200, a locking assembly 300, an elastic reset member 400, and a connecting assembly 500.

[0049] The housing 100 has an air intake channel 110, and an air inlet 120 communicating with the air intake channel 110 is provided on the housing 100. The air inlet 120 is used to draw hair, dust, dander, etc. into the air intake channel 110. When in use, hold the handle of the housing 100, with the air inlet 120 and the handle at an ergonomic angle, and place your thumb naturally on the push knob 320.

[0050] The brush head assembly 200 includes an adjusting member 210 and comb teeth 230. The adjusting member 210 is slidably mounted on the housing 100. The comb teeth 230 are fixedly connected to the adjusting member 210 and are arranged parallel to the air intake direction of the air inlet 120. The adjusting member 210 is used to adjust the length of the comb teeth 230 extending beyond the plane of the air inlet 120. The comb teeth 230 are used to straighten and comb the hair when sucking it up. The comb teeth 230 are located on the upper part of the air inlet 120, and when the adjusting member 210 is pushed and pulled back and forth, the comb teeth 230 move synchronously in a direction perpendicular to the plane of the air inlet 120 to adjust the length of the comb teeth 230 extending beyond the plane of the air inlet 120. The comb teeth 230 are detachably fixedly connected to the adjusting member 210 by screws, making it easy to replace different styles of comb teeth 230 according to the length and density of the pet's hair, such as silicone round-head comb teeth 230, straight steel needle comb teeth 230, rubber comb teeth 230 with massage heads, etc.

[0051] The elastic reset member 400 is disposed between the adjusting member 210 and the housing 100. The adjusting member 210 is provided with a cavity for accommodating the elastic reset member 400. One end of the elastic reset member 400 is fixedly connected to the adjusting member 210, and the other end is fixedly connected to the housing 100.

[0052] The locking assembly 300 includes a locking groove 310 and a push knob 320. The locking groove 310 is formed on the adjusting member 210, and the push knob 320 is slidably mounted on the handle of the housing 100. The push knob 320 is used to slide into the locking groove 310 to lock the position of the adjusting member 210. The locking groove 310 is a recess with one end open, and the push knob 320 is "L"-shaped. Pushing the push knob 320 upward inserts it into the locking groove 310. Since the inserted part just fills the locking groove 310, the adjusting member 210 cannot move back and forth at this time.

[0053] like Figure 6As shown, in this embodiment, the locking groove 310 includes a first locking groove segment 311 and a second locking groove segment 312. The first locking groove segment 311 and the second locking groove segment 312 are arranged sequentially back and forth along the sliding direction of the adjusting member 210, and are used to lock the length of the comb teeth 230 extending out of the air inlet 120 plane. Optionally, the locking groove 310 segment can also be provided with three or more locking groove segments 310. For example, a third locking groove segment 310 segment can be added between the first locking groove segment 311 and the second locking groove segment 312. When the push knob 320 is inserted into the third locking groove segment 310 segment, the length of the comb teeth 230 extending out of the air inlet 120 plane is between the maximum and minimum values. Different lengths of the comb teeth 230 extending out of the air inlet 120 plane can be applied to pets of different body sizes or different hair densities, thus improving the applicability of the suction head.

[0054] like Figure 5 and Figure 6 As shown, in this embodiment, when the push knob 320 is inserted into the second locking groove 312, the positions of the adjusting member 210 and the comb teeth 230 are locked. At this time, the length of the comb teeth 230 extending out of the air inlet 120 plane remains unchanged, so you can brush the hair with confidence. At this time, the suction head is equivalent to a pet-specific hair-brushing suction head.

[0055] like Figures 7 to 9 As shown, in this embodiment, when the push knob 320 is inserted into the first locking slot 311, the positions of the adjusting member 210 and the comb teeth 230 are locked, and at this time, the length of the comb teeth 230 extending out of the air inlet 120 plane is zero. When the pet hair remover switch is on, it can be used as a regular vacuum cleaner, or as a pet hair remover but without the combing function. When the pet hair remover switch is off, it can prevent pets or elderly people and children from being accidentally injured by the comb teeth 230 when the nozzle is idle, improving the safety of the nozzle. At this time, the nozzle is equivalent to a regular vacuum cleaner nozzle.

[0056] like Figure 4 As shown, in this embodiment, sliding protrusions 220 are provided on both inner sides of the adjusting member 210, and slide rails 130 are provided on both outer sides of the housing 100. The sliding protrusions 220 and slide rails 130 are used to cooperate with each other to guide the adjusting member 210 to slide on the housing 100. The direction of the slide rails 130 is consistent with the length direction of the comb teeth 230. The sliding adjusting member 210 controls the length of the comb teeth 230 extending out of the plane of the air inlet 120.

[0057] like Figure 6 As shown, in this embodiment, the opening direction of the locking groove 310 is perpendicular to the length direction of the comb teeth 230. Specifically, in this embodiment, the opening direction has a certain angle with the length direction of the comb teeth 230. This design is to conform to ergonomics and improve the grip experience. The housing 100 also includes a limiting stop block 140, which is used to limit the sliding direction of the push knob 320 from being parallel to the opening direction of the locking groove 310.

[0058] In this embodiment, the elastic reset member 400 is a tension spring, which provides a preload to bring the adjusting member 210 close to the air inlet 120 plane to keep the comb teeth 230 extending out of the air inlet 120 plane. When the push knob 320 is pushed down to disengage from the locking groove 310, the adjusting member 210 is in a freely sliding state. By default, when no force is applied, the comb teeth 230 extend out of the air inlet 120 plane, making it easy to pick up the suction head and use it directly. When combing, the comb teeth 230 will automatically retract behind the air inlet 120 plane according to the pressing force to prevent scratching the skin. Alternatively, the adjusting member 210 can be manually stretched to control the length of the comb teeth 230 extending out of the air inlet 120 plane.

[0059] In this embodiment, the elastic reset member 400 can also be a spring. The spring is used to provide a preload force to move the adjusting member 210 away from the air inlet 120 plane to limit the length of the comb teeth 230 extending out of the air inlet 120 plane. For example, using a spring with a suitable preload force, when the push knob 320 is pushed down to exit the locking groove 310, the adjusting member 210 is in a freely sliding state. When there is no force by default, the comb teeth 230 retracts behind the air inlet 120 plane and does not extend out. At this time, the suction head is equivalent to a regular vacuum cleaner, which can be used not only for pet grooming and removing hair and dander, but also for cleaning objects and other regular vacuum cleaner purposes, thus increasing the scope of use of the suction head. Moreover, in the default unforced state, the comb teeth 230 do not extend out of the air inlet 120 plane, which avoids pets or the elderly and children being accidentally injured by the comb teeth 230 when the suction head is idle, and also improves the safety of the suction head. The adjusting member 210 can also be manually stretched to control the length of the comb teeth 230 extending out of the air inlet 120 plane.

[0060] like Figures 10 to 12 As shown, in this embodiment, the hair vacuum cleaner head also includes a connecting assembly 500. The connecting assembly 500 includes a fixing member 510 and an insert member 520. The fixing member 510 is fixedly disposed on the housing 100, and the insert member 520 is used to insert into the fixing member 510 to connect the suction channel 110 and the insert member 520. Both the fixing member 510 and the insert member 520 are standard parts. When different styles and specifications of vacuum cleaner heads are equipped with the fixing member 510, the vacuum cleaner heads can be quickly replaced for different usage scenarios.

[0061] In this embodiment, the inner wall of the fixing member 510 is provided with an insertion groove section 511 and a rotating groove section 512 that are interconnected. The insertion groove section 511 and the rotating groove section 512 are parallel and the groove direction is consistent with the insertion direction of the inserter 520. The outer wall of the inserter 520 is provided with an insertion protrusion 521, which can be slidably accommodated in the insertion groove section 511 or the rotating groove section 512. When the inserter 520 is connected to the fixing member 510, the inserter 520 is first inserted upward into the fixing member 510, and the insertion protrusion 521 is inserted upward into the insertion groove section 511. After it is fully inserted, the inserter 520 is rotated to the right so that the insertion protrusion 521 is inserted to the right into the rotating groove section 512 and engages, thus completing the connection.

[0062] Another embodiment of this utility model provides a hair vacuum, including an air tube and a hair vacuum head as described above. One end of the air tube is fixedly connected to an insert 520, and the other end is connected to the hair vacuum body. The air tube communicates with the suction channel 110. When changing to a different type of suction head, only one end of the suction head fixing member 510 needs to be removed and installed; there is no need to disassemble or modify the insert 520 of the air tube.

[0063] In summary, this embodiment of the invention adjusts the length of the comb teeth 230 extending beyond the air inlet 120 plane via the adjusting member 210, and can be locked by the locking component 300, thus improving the safety and ease of use of the lint remover head. It is a lint remover head with adjustable settings, where the extension length of the comb teeth 230 is locked to zero when the head is not in use to prevent scratches, and the extension length of the comb teeth 230 can be precisely controlled.

[0064] Furthermore, through the design of multiple locking slots 310 at different distances, combined with the push-twist 320, the adjusting member 210 can be locked in different positions to lock and control the extension length of the comb teeth 230.

[0065] Furthermore, the adjusting member 210 is also provided with a cavity for accommodating the elastic reset member 400. One end of the elastic reset member 400 is fixedly connected to the adjusting member 210, and the other end is fixedly connected to the housing 100. If the elastic reset member 400 is a tension spring, the tension spring is used to provide preload so that the adjusting member 210 is close to the air inlet 120 in the default state to keep the comb teeth 230 extending out of the plane of the air inlet 120. In the default state, the push knob 320 is pushed away from the locking groove 310, and the comb teeth 230 extend out of the plane of the air inlet 120. The suction head can be picked up and used, improving efficiency. With the push knob 320 pushed away from the locking groove 310, the adjusting member 210 can still be pushed and pulled to temporarily control the length of the comb teeth 230 extending out of the plane of the air inlet 120. After releasing, the comb teeth 230 extend out of the plane of the air inlet 120 under the action of the tension spring.

[0066] Furthermore, if the elastic reset element 400 is a spring, the spring provides a preload to move the adjusting element 210 away from the air inlet 120, thereby limiting the length of the comb teeth 230 extending beyond the plane of the air inlet 120. In the default state, the push knob 320 is pushed away from the locking groove 310, and the comb teeth 230 are away from the plane of the air inlet 120. Depending on the preload of the spring, the comb teeth 230 may not extend beyond the plane of the air inlet 120, improving the safety of the suction head. Even with the push knob 320 pushed away from the locking groove 310, the adjusting element 210 can still be pushed or pulled to temporarily control the length of the comb teeth 230 extending beyond the plane of the air inlet 120. After releasing the spring, the comb teeth 230 will not extend beyond the plane of the air inlet 120.

[0067] Furthermore, the hair vacuum cleaner head also includes a connecting component 500, which includes a fixing member 510 and an insert member 520. The fixing member 510 is fixedly mounted on the housing 100, and the insert member is fixedly connected to the air tube of the hair vacuum cleaner. Both the insert member 520 and the fixing member 510 are standard parts, and they can be easily disassembled and assembled when changing to different styles of vacuum cleaner heads, thus improving replacement efficiency.

[0068] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
