Description

Technical Field

[0001] The utility model relates to the field of cleaning and suction devices, in particular to a suction head and household suction equipment designed in accordance with human body mechanics. Background Art

[0002] At present, the traditional cleaning method for cleaning carpets, sofas, curtains and floors is to use a hard brush to scrub the objects to be cleaned, which damages the objects to be cleaned, has a slow cleaning speed, and a slow drying speed after cleaning. The more conventional cleaning method is to use a wet cleaner, such as Figure 1-2 As shown, it at least includes a cleaning scraper head 1', which usually includes a scraper head body 11' and a water spray nozzle 12'. The scraper head body is a hollow structure, which is connected to the inner cavity of the suction pipe of the suction machine 2' to form a water suction channel; when the cleaning scraper head contacts and sucks back and forth on the surface of the cleaning object, the water spray nozzle supplies cleaning liquid to the surface of the cleaning object, and the scraper head body sucks back the cleaning liquid and stains on the surface of the cleaning object.

[0003] The existing water supply pipe assembly 13' connected to the water spray nozzle and the water suction pipe assembly 14' connected to the scraper head body are independent pipe assemblies. In order to meet the cleaning and suction effects, the water supply pipe assembly usually has a smaller diameter and the water suction pipe assembly has a larger diameter. The water supply pipe assembly is usually fixed to the bottom of the water suction pipe assembly through a clamp assembly 15' and close to one side of the scraper head body.

[0004] When cleaning, the user usually holds the water suction pipe assembly with a relatively large diameter to drive the entire cleaning spout to move back and forth on the surface of the object to be cleaned. However, since the fixing position of the clamp assembly is fixed at a single point, the water supply pipe assembly is easy to swing and the fixation is not firm enough. In addition, the existing water supply pipe assembly is provided with a mechanical handle switch 16' for controlling the opening and closing of the water spray nozzle. The switch is usually designed near the clamp assembly, so that the user can control the opening and closing of the water spray nozzle while holding the water suction pipe assembly. However, the above structures make it more laborious for the user to hold the water suction pipe assembly, which is not in line with the human body mechanics design. Utility Model Content

DETAILED DESCRIPTION

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0037] Example 1

[0038] like Figure 3-8 As shown, a suction spout 100 in accordance with ergonomic design comprises a water spray nozzle 1, a spout body 2, a water supply pipe 3, a water suction pipe 4, and a handle connector 5; the handle connector 5 is provided with a first mounting portion 51 for mounting the water supply pipe 3, a second mounting portion 52 for mounting the water suction pipe 4, and a hand-held portion 53 for facilitating the user to hold the suction spout or / and internal wiring; the first mounting portion 51 is located at the lower part of the second mounting portion 52, and the hand-held portion 53 is extended outward from the middle part of the second mounting portion 52, and is in an arc shape; the first mounting portion 51, the second mounting portion 52, and the hand-held portion 53 are integrally formed; the water supply pipe 3 is connected to the water spray nozzle 1, the water suction pipe 4 is connected to the spout body 2, and the water supply pipe 3 and the water suction pipe 4 are respectively mounted on the first mounting portion 51 and the second mounting portion 52 of the handle connector 5.

[0039] The present application adds a handle connector 5 to replace the simple clamp assembly in the prior art, and designs a first mounting portion 51, a second mounting portion 52, and a hand-holding portion 53 on the handle connector 5, so that the handle connector 5 has the function of firmly mounting the water supply pipe 3 and the absorption pipe, and also has the function of an external handle designed in accordance with ergonomics, so that the user can save effort and feel more comfortable during the cleaning process of the suction head.

[0040] As a further preferred solution, the handle connector 5 is composed of two symmetrically arranged first assembling pieces 501 and second assembling pieces 502, each of which has a first mounting portion 51, a second mounting portion 52, and a hand-held portion 53. The first assembling piece 501 and the second assembling piece 502 are provided with a plurality of fastening holes 503, and the first assembling piece 501 and the second assembling piece 502 are fixedly connected by fasteners. By designing a handle connector 5 of opposite splicing type, it is possible to meet the requirements of pipeline installation of complex structures and protect complex and easily consumable parts, such as the copper pipe assembly on the water supply pipeline 3.

[0041] As a further preferred solution, the first mounting portion 51 and the second mounting portion 52 are both accommodating cavities, and the size and shape of the accommodating cavities correspond to the diameter and shape of the water supply pipe 3 and the water suction pipe 4. By designing the first mounting portion 51 and the second mounting portion 52 to be cavity-shaped, the two pipes can be securely covered and installed, and the original single-point fixing method is replaced by a surface contact fixing method, making the pipe installation more secure and stable.

[0042] As a further preferred solution, both the first mounting portion 51 and the second mounting portion 52 are provided with a turning bend 54. The present application provides the turning bend 54 with the same bending arrangement on the first mounting portion 51 and the second mounting portion 52, so as to change the direction of the water supply pipe 3 and the water suction pipe 4. On the one hand, it can meet the curvature design requirements related to the ergonomics of the handle, and on the other hand, the most vulnerable bending part of the pipe is hidden in the handle connector, so as to protect the vulnerable bending part of the pipe and improve the quality of the product.

[0043] As a further preferred solution, a multi-position switch 55 for controlling at least the water spraying, steam spraying and water stopping functions of the water spraying nozzle is provided on the outer side of the handheld portion 53. The present application designs the switch function of the water spraying nozzle 1 on the handheld portion 53 through circuit routing design, replacing the mechanical handle switch originally located on the water supply pipe 3. This design is more in line with human mechanics.

The present application improves the installation firmness between the head body 2, the water suction pipe 4, and the handle connector 5 by designing the quick-release connector 6, on the one hand, and facilitates the rapid installation of the head body on the other hand.

[0046] As a further preferred embodiment, the ergonomically designed suction head 100 further includes a splash shield 7. The splash shield 7 has a semi-enclosed space for accommodating a water nozzle, and a limit fastener extends upward from the top of the splash shield 7, the height of which is greater than the thickness of the head body 2; the splash shield 7 covers the water nozzle in the semi-enclosed space, and the limit fastener is pressed upward on the top of the head body 2, so that the splash cover can be detachably installed on the head body 2. The present application separates the splash shield 7 and detachably installs it on the head body 2. This design makes it easy for the user to select the suction function of the head body 2 for dry cleaning or the combination of the head body 2 and the water nozzle for wet cleaning according to the actual usage scenario, which has a wider usage scenario and a larger scope of application.

[0047] As a further preferred solution, the suction head 100 in accordance with the ergonomic design also includes a blocking baffle 8 arranged on the opening of the head body 2. The blocking baffle 8 includes a baffle 81 arranged in a parallel direction and a baffle rod 82 arranged in a vertical direction, and the baffle rod 82 is penetrated on the head body 2. The present application embeds the conventional extended baffle 81 in the suction port, which can reduce the thickness and volume of the head body 2 on one side, making it more convenient to extend into a small gap for cleaning. On the other hand, the criss-crossing baffles 81 and baffle rods 82 cooperate with each other, which can further reduce the probability of small objects being accidentally sucked into the suction port.
