The present invention relates to the technical field of hairdressing devices and in particular to a water-pumping device and a hairdressing device.
With the improvement of people's living standards and the pursuit of hairdressing art, hairdressing devices are increasingly widely used. For example, for a hair straightener, in order to reduce damage to hair during hair straightening, a steam hair straightener emerges on the market that is connected to a water delivery mechanism and evaporates water into steam during hair straightening to moisten the hair. However, the existing water delivery mechanism needs to be additionally provided with a hose as a water delivery pipe to deliver water. As a result, there are too many components and the structure is complex.
In order to solve the problem that the existing water delivery mechanism has too many components and a complex structure, the present invention provides a water-pumping device and a hairdressing device.
In order to solve the above problem, the present invention provides a water-pumping device connected to a liquid storage device to deliver a liquid in the liquid storage device; the water-pumping device includes a chamber for containing the liquid and a squeezing device; two opposite ends of the chamber are communicated with a first water delivery channel and a second water delivery channel respectively; the first water delivery channel is connected to the liquid storage device; a wall surface of the chamber is at least partially made of a deformable material, and the squeezing device periodically squeezes the deformable material from one end of the chamber to the other end thereof to make the first water delivery channel pump water and the second water delivery channel deliver water.
The present invention also provides a hairdressing device that includes a water-pumping device and a liquid storage device which are connected; the water-pumping device includes a chamber for containing a liquid and a squeezing device; two opposite ends of the chamber are communicated with a first water delivery channel and a second water delivery channel respectively; the first water delivery channel is connected to the liquid storage device, and a wall surface of the chamber is at least partially made of a deformable material; the squeezing device periodically squeezes the deformable material from one end of the chamber to the other end thereof to make the first water delivery channel pump water and the second water delivery channel deliver water.
Preferably, the liquid storage device includes a tank, a water guide pipe, and a first water suction member; one end of the water guide pipe passes through the water tank to be communicated with the outside, and the opposite end thereof is connected to the first water suction member; one end of the first water suction member is disposed on the water guide pipe and the opposite end thereof extends in the tank.
Compared with the prior art, the water-pumping device and the hairdressing device according to the present invention have the benefits as follows.
The water-pumping device according to the present invention may be connected to the liquid storage device to deliver the liquid in the liquid storage device; the water-pumping device includes a chamber for containing the liquid and a squeezing device; two opposite ends of the chamber are communicated with a first water delivery channel and a second water delivery channel respectively; the first water delivery channel is connected to the liquid storage device; the wall surface of the chamber is at least partially made of a deformable material, and the squeezing device periodically squeezes the deformable material from one end of the chamber to the other end thereof to make the first water delivery channel pump water and the second water delivery channel deliver water; since the chamber does not need to be additionally provided with a hose to contain the liquid, the number of components is reduced, the overall structure is simplified, and the water-pumping device is simpler in structure.
The hairdressing device according to the present invention includes the above water-pumping device and the liquid storage device which are connected; the hairdressing device has the same benefits as the above water-pumping device, which are not repeated here.
For the liquid storage device, the liquid in the tank can be sucked through the first water suction member; the first water suction member extends to an end, away from a water outlet, in the tank, and can suck the liquid, away from the water outlet, in the tank when there is little liquid in the tank; in addition, an end, away from the water outlet, of the first water suction member can move at the end, away from the water outlet, in the tank, so that the first water suction member can suck the liquid when the tank is inclined and discharge the liquid to the outside, so that the liquid utilization rate is increased, and the situation that the first water suction member cannot suck the liquid when the tank is inclined is avoided.
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention instead of limiting the present invention.

Specifically, the chamber p is defined by a hard wall surface and a deformable wall surface. In some embodiments, the chamber p may be entirely defined by the deformable wall surface.

Specifically, with reference to
Specifically, the baffle 13 is made of a deformable material. The thickness of one side of the baffle 11 close to the flexible pump core 11 is less than that of the side thereof away from the flexible pump core 11. When the squeezing device 14 squeezes to a position of the flexible pump core 11 corresponding to the baffle 13, the side of the baffle 13 close to the flexible pump core 11 moves to the side away from the flexible pump core 11 to make way for the squeezing device 14 and thus the squeezing device 14 continues to move.
Specifically, the chamber p is ring-shaped with an opening. The baffle 13 is located at the opening of the chamber p. The squeezing device 14 is an eccentric wheel 141. In some embodiments, the squeezing device 14 may be a circular roller or others. The chamber p may be of other shapes, such as fan-shaped, an elliptic-shaped with an opening, or linear-shaped, as long as two opposite ends of the chamber p are communicated with the first water delivery channel 121 and the second water delivery channel 122 respectively. The squeezing device 13 periodically squeezes the deformable material from one end of the chamber p to the other end thereof to make the first water delivery channel 121 pump water and the second water delivery channel 122 deliver water.
Optionally, the flexible pump core 11 may be entirely made of a deformable material. By changing the thickness of the deformable material, part of the flexible pump core 11 can play a role of supporting. For example, the flexible pump core 11 has a thicker upper surface and a thicker lower surface, which may support the flexible pump core 11 and thus the flexible pump core 11 has a certain shape. The flexible pump core 11 has a relatively thin middle portion which may be subjected to a certain deformation by squeezing and may basically return to its original shape when the squeezing force is removed. Preferably, the flexible pump core 11 is made of rubber. As such, the flexible pump core 11 is subjected to certain deformation when being squeezed and the chamber p has a good sealing property to prevent water leakage. In some embodiments, the flexible pump core 11 may also be made of other deformable materials, such as silica gel, as long as the flexible pump core 11 may be subjected to certain deformation when being squeezed and the chamber p has a good sealing property.
It may be understood that the interior of the flexible pump core 11 may be partially made of a deformable material that can be deformed by squeezing or entirely made of a deformable material that can be deformed by squeezing, as long as the portion, in contact with the squeezing device 14, of the flexible pump core 11 is made of a deformable material, that can be deformed by squeezing.
Optionally, the outer bracket 12 may be entirely made of a hard material, partially made of a hard material and partially made of a deformable material, or entirely made of a deformable material with a low deformation degree, as long as the outer bracket 12 plays a role of supporting when the outer bracket 12 is sleeved on the outer peripheral side of the flexible pump core 11, and the outer bracket 12 and the flexible pump core 11 together define the chamber p.

A first groove 123 and a first boss 162 that match each other are disposed on surfaces, facing each other, of the outer bracket 12 and the upper cover 16 respectively (as shown in
Optionally, one of the first groove 123 and the first boss 162 is disposed on the outer bracket 12 and the other is disposed on the upper cover 16. One of the second groove 124 and the second boss 172 is disposed on the outer bracket 12 and the other is disposed on the lower cover 17.
It may be understood that by butting the first water delivery pipe 161 and the first water delivery channel 121, and butting the second water delivery pipe 171 and the second water delivery channel 122, an outlet and an inlet of the liquid are exposed. Therefore, the device may be used by directly connecting water pipes with the first water delivery pipe 161 and the second water delivery pipe 171 and it is convenient to pump water into the water-pumping device 10 from the liquid storage device and introduce the liquid into other devices after the liquid is delivered out of the water-pumping device 10. In addition, as the first groove 123 and the first boss 162 as well as the second groove 124 and the second boss 172 are disposed, when the outer bracket 12 is connected to the upper cover 16 and the lower cover 17, it is convenient to accurately butt the first water delivery pipe 161 and the first water delivery channel 121 and butt the second water delivery pipe 171 and the second water delivery channel 122, thereby preventing water leakage caused by inaccurate butting. In addition, the rigidity of the outer bracket 12 can be limited, and shaking due to a squeezing force of the squeezing device 14 and the outer bracket 12 is avoided during working, thereby improving the stability of delivering the liquid. The fixing of the outer bracket 12 ensures the forming of the flexible pump core 11, thereby improving the liquid delivery effect.

As a variant embodiment, the first water delivery channel 121 and the second water delivery channel 122 may be disposed on the flexible pump core 11, or one of the first water delivery channel 121 and the second water delivery channel 122 is disposed on the flexible pump core 11 and the other is disposed on the outer bracket 12, as long as the first water delivery channel 121 is connected to the liquid storage device and the two opposite ends of the chamber p are communicated with the first water delivery channel 121 and the second water delivery channel 122 respectively.
In some variant embodiments, the flexible pump core 11 may be provided with no water delivery hole 111. The first water delivery pipe 161 directly corresponds to the first water delivery channel 121 and the second water delivery pipe 171 directly corresponds to the second water delivery channel 122 as long as the first water delivery pipe 161 is correspondingly communicated with the first water delivery channel 121 when the first boss 162 is inserted into the first groove 123, and the second water delivery pipe 171 is correspondingly communicated with the second water delivery channel 122 when the second boss 172 is inserted into the second groove 124.
In some variant embodiments, the first boss 162 may also be disposed on an edge of the surface, facing the outer bracket 12, of the upper cover 16, and at the same time, the first groove 123 is formed in a corresponding position of the surface, facing the upper cover 16, of the outer bracket 12, so that when the upper cover 16 is connected to the outer bracket 12, the first boss 162 is just inserted into the first groove 123; or the first groove 123 is formed in a corresponding position of the periphery of the outer bracket 12, so that when the upper cover 16 is connected to the outer bracket 12, the first boss 162 is just clamped in the first groove 123. For the same reason, the second boss 172 may also be disposed on an edge of the surface, facing the outer bracket 12, of the lower cover 17, and at the same time, the second groove 124 is formed in a corresponding position of the surface, facing the lower cover 17, of the outer bracket 12, so that when the lower cover 17 is connected to the outer bracket 12, the second boss 172 is just inserted into the second groove 124; or the second groove 124 is formed in a corresponding position of the periphery of the outer bracket 12, so that when the lower cover 17 is connected to the outer bracket 12, the second boss 172 is just clamped in the second groove 124.
Optionally, the outer bracket 12 is connected to the upper cover 16 and the lower cover 17 by any of magnetic attraction, clamping and threaded connection. The connection mode of the outer bracket 12 with the upper cover 16 and the lower cover 17 is not limited as long as the outer bracket 12 may be tightly connected to the upper cover 16 and the lower cover 17 and the disassembly is convenient for facilitating cleaning and maintenance of the internal structure of the water-pumping device 10.

It may be understood that the water guide pipe 32 may be connected to a water pump, through which the liquid in the tank 31 is discharged. For example, in a steam hair-straightening device, the liquid in the tank 31 is pumped out through a peristaltic pump.
It may be understood that the water guide pipe 32 is in interference fit with the first water suction member 33, so that a connection position of the water guide pipe 32 and the first water suction member 33 is sealed, thereby avoiding the failure of pumping water due to loose connection and improving the stability of pumping water.
Specifically, the tank 31 includes a first housing 311 and a second housing 312. The first housing 311 is buckled on the second housing 312. An accommodating space for liquid storage is defined between the first housing 311 and the second housing 312, and the first water suction member 33 and a portion of the water guide pipe 32 are disposed therein. A water outlet 3121 is formed on the second housing 312. The water guide pipe 32 runs through the second housing 312 through the water outlet 3121 to output the liquid in the tank 31 to an external device. Particularly, after the first water suction member 33 sucks the liquid, an end, away from the water guide pipe 32, of the first water suction member 33 has an increased weight due to liquid suction and may move in the tank 31. When there is little liquid in the tank 31, the end, away from the water guide pipe 32, of the first water suction member 33 may move to a liquid position to suck the liquid and then discharge the liquid to the water guide pipe 32.
It may be understood that the water guide pipe 32 and the first water suction member 33 are disposed in the accommodating space of the tank 31, and the first water suction member 33 is in contact with the liquid in the tank 31, so that the liquid in the tank 31 may enter the external device through the water guide pipe 32. The first water suction member 33 sucks the liquid in the tank 31 and the external device draws the liquid from the liquid storage device 30. As the air pressure outside the tank 31 is less than the air pressure inside the tank, the first water suction member 33 delivers the liquid in the tank 31 to the external device through the water guide pipe 32 by means of a wicking effect.
Optionally, a load block 3248 is disposed at the end, away from the water guide pipe 32, of the first water suction member 33, so that when the tank 31 is in a holding state, the end of the first water suction member 33 with the load block 3248 may move in the tank 31 to the position where the liquid is located in the tank 31. Thus, it is ensured that the first water suction member 33 can discharge the liquid.
With continued reference to
Optionally, the water guide pipe 32 is made of a flexible material, so that the water guide pipe 32 may be elastically deformed at the position of the first through hole 321, that is, the first through hole 321 may be deformed to increase the movement range of the first water suction member 33. The end, away from the water guide pipe 32, of the water suction member 33 may move to more positions in the tank 31 to suck the liquid, thereby increasing the utilization rate of the liquid in the tank 31.
Optionally, the first through hole 321 is in interference fit with the first water suction member 33 to maintain the sealing therebetween and thus prevent the failure of water suction due to air leakage of the first through hole 321.
With continued reference to
Specifically, a user may inject the liquid into the tank 31 through the water injection hole 3111 and the cover 3112 may seal the water injection hole 3111, so that the tank 31 filled with the liquid keeps a sealed state. The vent hole 3114 may keep the air pressure inside and outside the tank 31 balanced. The barrier 3113 may block the vent hole 3114 to prevent the liquid from leaking from the vent hole 3114.
With reference to
Specifically, the auxiliary water suction assembly 324 is disposed at a position, close to the water outlet 3121, of the tank 31 to suck the liquid at the water outlet 3121 in the tank 31. It may be understood that when there is little liquid in the tank 31, the auxiliary water suction assembly 324 may normally provide the liquid while the first water suction member 33 of the liquid storage device 30 provides little liquid, thereby increasing the liquid utilization rate of the liquid storage device 30.
With continued reference to
Specifically, the second water suction pipe 3242 is embedded into the auxiliary water suction pipe 3241 and the length thereof is greater than that of the auxiliary water suction pipe 3241, so that one end of the second water suction member 3242 is exposed to the auxiliary water suction pipe 3241. One end of the auxiliary water suction pipe 3241 is connected to a pipe body of the water guide pipe 32 and the opposite end thereof extends towards the inner surface of the tank 31. The end, away from the water guide pipe 32, of the second water suction member 3242 sucks the liquid and delivers the liquid to the water guide pipe 32, so that the liquid at the position where the second water suction member 3242 is located away from the water outlet 3121 in the tank can be used. By forming the second through hole 3243 in the auxiliary water suction pipe 3241, the contact area of the second water suction member 3242 and the liquid is increased and the liquid at the position of the auxiliary water suction pipe 3241 in the tank 31 is sucked by the second water suction member 3242. Thus, the utilization rate of the liquid in the tank 31 is increased. Of course, the length of the second water suction member 3242 may be less than or equal to that of the auxiliary water suction pipe 3241, as long as the second water suction member 3242 can be placed in the auxiliary water suction pipe 3241 and suck water.
Optionally, the first water suction member 33 and the second water suction member 3242 may be a cotton stick or other materials having a wicking effect.
Optionally, the number of the second through holes 3243 may be one, two, three or more than three, as long as the second water suction member 3242 may pass through the second through hole 3243 to contact the liquid. In this embodiment, the number of the second through hole 3242 is one, but the number thereof is not limited in this embodiment.
Optionally, the auxiliary water suction pipe 3241 extends to the inner surface of the tank 31 to increase the utilization rate of the liquid in the tank 31.
Optionally, the water guile pipe 32 adopts the structure of a T-shaped three-way pipe. It may be understood that the auxiliary water suction pipe 3241 and the water guide pipe 32 are vertically disposed.
Optionally, the auxiliary water suction pipe 3241 and the wall surface of the end, close to the water outlet 3121, the tank 31 have the same size, which can increase the utilization rate of the liquid at a lower water level.
With reference to
Specifically, the drainage member 3245′ defines a drainage port 3249′ on the side close to the surface of the tank 31′. The water suction block 3244′ is in contact with the inner surface of the tank 31′ and is in interference connection with the drainage port 3249′. The water suction block 3244′ sucks the liquid close to the water outlet 3121′ in the tank 31′ and discharges the liquid through the drainage member 3245′, so that the liquid close to the water outlet 3121′ in the tank 31′ is sucked by the water suction block 3244′, thereby increasing the utilization rate of the liquid in the tank 31′. Preferably, the water suction block 3244′ may be any of water suction materials such as a cotton stick and sponge.
Optionally, the water guide pipe 32′ includes a compression portion 122′ and a connection portion 123′. The connection portion 123′ is connected to one end of the first water suction member 33′ and the compression portion 122′ is compressible. The first water suction member 33′ approaches the water guide pipe 32′ by compressing the compression portion 122′, so that the liquid, close to the water guide pipe 32′, in the tank 31′ is sucked by the first water suction member 33′ and is delivered to an external device. Further, the first water suction member 33′ compresses the compression portion 122′ to move in the tank 31′, thereby increasing the movement range of the first water suction member 33′.
Optionally, the number of the drainage ports 3249′ may be one, two, three or more than three, as long as the water suction block 3244′ may pass through the drainage port 3249′ to contact the liquid. In this embodiment, the number of the drainage port 3249′ is one, but the number thereof is not limited in this embodiment.
It may be understood that the water suction block 3244′ is in interference fit with the drainage member 3245′, so that a connection position of the water suction block 3244′ and the drainage member 3245′ is sealed, thereby avoiding the failure of pumping water due to loose connection and improving the stability of pumping water.
With reference to
Specifically, two ends of the fixed pipe 3247″ are open. The second water suction member 3242″ is embedded into the fixed pipe 3247″ and may be in contact with liquid through two ends exposed to the fixed pipe 3247″. As such, the liquid at the position of the fixed pipe 3247″ is further utilized. At the same time, the user may tilt the liquid in a tank 330″ towards this position, so that the second water suction member 3242″ may suck the liquid. Further, the second through hole 3243″ is formed in the fixed pipe 3247″ to increase the contact area between the second water suction member 3242″ and the liquid, thereby increasing the utilization rate of the liquid.
It may be understood that the length of the second water suction member 3242″ may be less than, greater than or equal to the length of the fixed pipe 3247″, as long as the second water suction member 3242″ is fixed in the fixed pipe 3247″ and sucks water.
Optionally, the number of the second through holes 3243″ may be one, two, three or more than three, as long as the second water suction member 3242″ may pass through the second through hole 3243 to contact the liquid. In this embodiment, the number of the through hole 3242″ is one, but the number thereof is not limited in this embodiment.
It may be understood that the fixed pipe 3247″ is in interference fit with the second water suction member 3242″, so that a connection position of the fixed pipe 3247″ and the second water suction member 3242″ is sealed, thereby avoiding the failure of pumping water due to loose connection and improving the stability of pumping water. The second through hole 3243″ is in interference fit with the second water suction member 3242″ to maintain the sealing therebetween and prevent the failure of water suction due to air leakage of the second through hole 3243″.
With reference to
It may be understood that when being used, the hairdressing device 20 usually needs to be held and used at many angles (for example, a portable steam hair straightener needs to be lifted to meet the requirements of straightening hair at various angles). As a result, the liquid storage device 22 in the device also needs to change the angle, and the liquid in the liquid storage device 22 will move to different positions. When the liquid moves close to the water outlet, the liquid may be continued to be sucked through the liquid storage device 22. Thus, the utilization rate of the liquid is increased and the failure of water suction due to liquid inversion is avoided.
As an embodiment,
The water-pumping device and the hairdressing device provided by the embodiments of the present invention have been described in detail above. Specific examples are used herein to explain the principles and implementation modes of the present invention. The descriptions of the above embodiments are only configured to help understand the method and the core concept of the present invention. Meanwhile, for a person of ordinary skill in the art, there will be changes in the specific implementation mode and the application scope according to the concept of the present invention. In summary, the content of the description should not be understood as a limitation to the present invention. Any modifications, equivalent replacements, improvements and the like made within the principles of the present invention should be included within the scope of protection of the present invention.
