Abstract

A cold and hot air mixing blower comprises a body and a handle. The body comprises an outer wall, an embedded pipeline, a flow distribution pipeline, a fluid director, a fan and a heating assembly. The fluid is sucked into the body through the fan and then is divided into a first fluid and a second fluid through the diversion pipeline, wherein the first fluid enters the cavity formed by the outer wall and the embedded pipeline through the fluid director and flows out after being heated by the heating component, the second fluid flows out through the cavity formed by the embedded pipeline without being heated by the heating component, and the first fluid and the second fluid are converged at the front part of the body and then flow out of the body. Compared with the existing air blowing machine with air inlet at the rear, the air blower realizes that the fluid is firstly shunted in the body and then the partially shunted fluid is heated, thereby realizing that cold air and hot air are mixed and flow out of the body, effectively reducing the air temperature of the fluid, better protecting the hair or scalp and the like, and improving the hair styling efficiency by mixing the cold air and the hot air.

Description

Cold and hot air mixing blower

Technical Field

The invention relates to a handheld daily appliance, in particular to a hair drier with a cold and hot air mixing function.

Background

A hair dryer, in particular a hot air hair dryer, is a household appliance with a drying function. Additionally, hot air blowers have also been used to style hair from wet or dry environments.

Generally, a hair dryer includes a fan assembly and a heating assembly, and air is sucked into a body through the fan assembly and heated by the heating assembly, thereby achieving a drying purpose. The speed and the shape of the air flowing out are changed by the additional air nozzle part which can be automatically disassembled and assembled by a user, so that different use purposes such as quick drying, modeling and the like are achieved.

Currently, existing hair dryers can be broadly divided into two types: 1. and the fan assembly is positioned at the rear end of the body and sucks air, the air flows out of the body after being heated by the heating assembly at the front end of the body or flows out of the body after passing through the additional air nozzle, and due to the influence of the central fan assembly and the heating assembly, the central flow rate of the outflow air is low, the temperature is high, the user experience is poor, and the service lives of the fan assembly and the heating assembly are influenced. 2. Handle tip air inlet hair-dryer, fan unit is arranged in the handle, inhales the air from the handle bottom, takes place to turn to through the heating element behind the entering body through fluid route, flows out the body after the heating, or flows out behind the additional tuyere, simultaneously through the cavity formula design in the body, utilizes front and back end pressure difference guide cold wind to meet through hollow structure and heating back main fluid and realize that cold and hot wind mixes, effectively reduces the wind-warm syndrome, promotes consumer and uses experience.

Detailed Description

The technical scheme of the invention is described in detail in the following with reference to the accompanying drawings. Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.

Fig. 1 is an exploded view of an embodiment of a hair dryer of the present invention, and fig. 2 is a sectional view of the hair dryer of the present invention. As shown in fig. 1 and 2, the hair dryer includes a body (100) and a handle (200). The body (100) consists of an outer wall (101), an embedded pipeline (102), a diversion pipeline (103), a fluid director (104), a fan assembly (105) and a heating assembly (106). The diversion pipeline is connected with the fan mechanism, the main body part of the fluid director is arranged in the cavity of the diversion pipeline, and the fluid director is assembled with the embedded pipeline, so that the opening end of the fluid director is in interference fit with one end of the embedded pipeline. The included angle formed by the flow guider and the assembly position of the embedded pipeline is 90-180 degrees.

The blower body contains 2 fluid flow paths and at least 3 chambers. The first cavity is formed between the outer wall of the body and the embedded pipeline, the inner cavity of the embedded pipeline is the second cavity, and the space enclosed by the inner wall of the diversion pipeline and the outer wall of the fluid director forms the third cavity.

Figure 3 is an enlarged cross-sectional view of the diverging duct section of a hair dryer in accordance with the present invention. The section of the flow dividing pipeline in the hair drier body in the direction parallel to the front end face and the rear end face of the body is of a semi-open structure, one part of the flow dividing pipeline and the fluid director form a closed cavity which is communicated with the first cavity, and the other part of the flow dividing pipeline is communicated with the space of the inner cavity of the body and is in an open state.

Figure 4 is a schematic view of the path of fluid movement of a hair dryer of the present invention. The fluid is sucked into the body (100) through the fan assembly (105) and then is divided into a fluid A and a fluid B through the diversion pipeline (103), wherein the fluid A enters a cavity formed by the outer wall (101) and the embedded pipeline (102) through the fluid director (104) and is heated by the heating assembly (106) and then flows out, the fluid B flows out through the cavity formed by the embedded pipeline (102) without being heated by the heating assembly (106), and the fluid A and the fluid B flow out of the body (100) after meeting at the front part of the body (100). Compared with a common rear air blowing machine, the air blower realizes that the fluid A flows through the heating assembly (106) after the fluid A is divided into the fluid A and the fluid B in the body (100), and the fluid B does not flow through the heating assembly, thereby realizing the mixing of cold air and hot air and flowing out of the body (100), effectively reducing the air temperature of the fluid, better protecting the hair, scalp and other parts of a consumer, and improving the hair styling and shaping efficiency by mixing the cold air and the hot air; compared with a Dyson handle air inlet type hair drier, the hair drier has the advantages that the fluid is directly divided into the fluid A and the fluid B in the body (100), the moving path of the fluid is shorter, the efficiency is improved, the length of the handle does not need to be prolonged to be used as a main fluid inlet, the human-machine requirement of a consumer for holding the handle is better met, and the difference is that Dyson enables a part of the fluid to flow from one end of the body to the other end through the pressure difference between two ends of the body.

The hair-dryer that this embodiment provided has realized the body rear end air inlet, and the fluid is divided by the reposition of redundant personnel pipeline at this internal two parts, and one of them part is through heating element, and partly do not pass through heating element in addition, and cold and hot two partial fluids flow out after this internal front portion cold and hot mixes, effectively reduce the air outlet wind-warm syndrome, promote consumer and use experience.
