Description

Technical Field

[0001] The invention belongs to the technical field of sanitary ware, and in particular relates to a defecation spray head used on an intelligent toilet. Background Art

[0002] Smart toilets generally have a buttocks cleaning function, and some smart toilets currently also have a laxative function. The working principle of a smart toilet with a laxative function is that it uses a laxative nozzle to aim at the anus and spray a high-pressure water column into the rectum, so that the feces in the rectum are filled with water and softened, and the rectum is filled with water to stimulate the anus to defecate. Therefore, the quality of the laxative effect depends on the angle and strength of the water outlet of the laxative nozzle. If the pressure of the water outlet of the nozzle is too low, the sprayed water column will not be able to enter the human rectum and achieve the laxative effect. How to design the internal structure of the laxative nozzle so that the water column of the laxative nozzle has a suitable pressure and aggregation state, which is convenient for spraying into the rectum, is a key technical issue.

[0003] Chinese patent CN1997798A discloses a bidet with enema function, the bidet is constructed in such a way that anal cleaning function, bidet cleaning function and enema function are arranged in a single nozzle. The nozzle structure comprises: a spray cover (3520) having an enema hole for performing the enema function, wherein a guide groove (3610) is formed protruding downward from the upper part of the enema spray hole (3523) to prevent the washing water passing through the discharge hole (3524) formed in the enema spray hole (3523) of the spray cover (3520) from forming turbulence, and the nozzle structure comprises a washing water guide rib (3630) having a guide hole (3620) formed in the guide groove (3610) in a straight line flow communication, and the washing water does not generate turbulence and thus bubbles. In this solution, the nozzle pipeline body is a guide groove (3610), which includes a guide hole (3620) with a thinner aperture section, and a main section of the guide groove (3610) provided with a cleaning water guide rib (3630) and a thicker aperture section.

[0004] Chinese patent CN101886420A discloses an electronic toilet with enema function, wherein the inner hole of the enema flushing nozzle (12a) is in the shape of a truncated cone, the water inlet diameter (ΦB) of the inner hole is larger than the water outlet diameter (ΦA), and the cone vertex angle α of the truncated cone inner hole satisfies 0<α≤15°. The ratio of the water outlet diameter (ΦA) of the inner hole to the length (L) of the inner hole is 1:3-20. It is clear that in this solution, the nozzle water inlet aperture is larger than the water outlet aperture.

[0005] Chinese patent CN205636989U discloses an electronic toilet for enema and defecation, wherein the inner wall of the defecation pipe 33 connected to the spray hole 32 is smooth and has an arc-shaped local gathering structure from a wide mouth to a narrow mouth; this water flow gathering structure can make the water flow spray out in a water column, and the smooth inner wall does not lose water pressure.

[0006] In the above-mentioned nozzle technical scheme, the water outlet pipeline can be divided into an axial tube arranged along the axial direction of the nozzle and a radial pipe section arranged along the radial direction of the nozzle. In the radial pipe section, the aperture of the water inlet pipe section is larger than the water outlet aperture. People in the technical field generally believe that this kind of pipeline convergence or conical structure can make the water flow out in the form of a water column. Summary of the invention

[0007] In order to design the internal water outlet pipeline structure of the laxative nozzle so that the water column of the laxative nozzle has a suitable pressure and aggregation state, so as to achieve the effect of spraying into the rectum, the present invention provides a nozzle with an inverted cone-shaped water outlet pipeline structure, the water column sprayed out by the nozzle maintains a columnar shape and has a higher spray height, so that the water column can more conveniently enter the human rectum.

[0008] The first technical solution proposed by the present invention is:

[0009] A laxative nozzle comprises a nozzle body (10), wherein a laxative water pipeline is arranged in the tube body, and the laxative water pipeline is sequentially divided into an axial tube (31) arranged along the axial direction of the nozzle, a bend tube (32), and a radial tube (33) arranged along the radial direction of the nozzle, characterized in that the diameter of the radial tube (33) in the laxative water pipeline gradually increases from the water inlet end to the water outlet end, the diameter of the water inlet of the radial tube (33) is set at 1.3mm-3mm, and the diameter of the water outlet is set at 1.4mm-1.6mm; the bend tube (32) and the axial tube (31) are tapered inner cavity pipelines with gradually decreasing diameters from the water inlet end to the water outlet end, the diameters of the water inlet and water outlet of the bend tube (32) are set between 1.6 and 3mm, and the diameters of the water inlet and water outlet of the axial tube (31) are set between 1.6 and 6mm.

[0010] Another disclosure of the present invention provides a toilet using the above-mentioned nozzle, including a retractable nozzle installed, the nozzle is installed on the nozzle, the flushing water pipeline in the nozzle body forms a straight water inlet pipe section, the axial pipe has a first pipe section, and the nozzle is provided with two groups of joint inner tubes with sealing rings, the two groups of joint inner tubes are respectively inserted into the straight water inlet pipe section and the first pipe section on the axial tube, and the nozzle body is installed on the nozzle.

[0011] Preferably, the contact surface between the nozzle tube body and the nozzle is provided with two symmetrical first positioning grooves and second positioning grooves of different widths, and the nozzle shell is provided with two corresponding positioning blocks of different widths, and the two sets of positioning blocks are positioned and connected with the first positioning groove and the second positioning groove in the same width.

[0012] Preferably, the toilet is provided with a water inlet pipe connected to the spray pipe, a heater for heating the incoming water, a control circuit and a valve for controlling the on-off of the water inlet pipe, and the heater is an instantaneous heater.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. To design the internal water outlet pipeline structure of the laxative spray head, so that the water column of the laxative spray head has a suitable pressure and gathering state, it is convenient to spray in. The prior art and the technicians believe that the water outlet hole section of the spray head should be a tapered pipeline with a coarse water inlet hole and a fine water outlet hole, so as to facilitate the gathering of the water outlet pressure and form a long columnar shape. However, the radial pipe disclosed in the present invention is a thin lower and thick upper pipeline with a fine water inlet hole and a coarse water outlet hole. The aperture of the combined water outlet hole of this pipeline is set under the condition of a relatively fine aperture of 1.3mm to 1.5mm. It can be obtained from experimental data that under the aperture condition of the micro-water outlet hole, the lower thin upper thick structure formed by the pipeline as a whole can reach more than ten centimeters in height of the sprayed water column without divergence, but can form a better converged water column shape, which is more convenient for subsequent spray defecation. At the same time, the axial pipe (31) and the turning pipe (32) can still enable the water flow to achieve secondary pressurization by being set as a tapered inner cavity pipeline.

[0015] 2. The radial tube disclosed in the present invention is in the shape of a pipe with a thin water inlet hole and a thick water outlet hole, which is convenient for the integral injection molding of the laxative tube body. However, the radial tube of the traditional structure is in the shape of a truncated cone with a thick water inlet hole and a thin water outlet hole. Due to the limitation of mold demoulding, the laxative tube body must be divided into two parts for separate molding and welding assembly, which increases the manufacturing cost.

[0016] 3. The turning tube (32), the axial tube (31) and the radial tube (33) are provided with spiral grooves of continuous double helical threads. Due to the rotating effect of the double helical threads on the water flow, the water flow is rotated, and the straight water column is changed into a rotating water column, so that the ejected water column has a linear impact force and a rotating impact force, which makes it easier to achieve the effect of ejecting into the rectum.

[0017] 4. The present invention discloses a method of setting the radial tube (33) as a split tube body, wherein the outer side of the radial tube (33) is provided with an external thread, and the nozzle tube body (10) is provided with a cylindrical cavity with an internal thread; the radial tube (33) is threadedly connected to the cylindrical cavity of the nozzle tube body (10). The advantage of such a structure is that the radial tube (33) is not installed, and the turning tube can be directly used for flushing and buttock washing because of the low water pressure and large aperture. When laxative flushing is required, the radial tube can be installed, and at the same time, the pipelines in the radial tube can be set to 2-3, so as to achieve more diversified rotation.

[0018] 5. The turning pipe and the axial pipe in the nozzle pipe body disclosed in the present invention are both configured with smooth inner walls, and the aperture gradually tapers from the water inlet to the water outlet, which has the effect of increasing the outlet water pressure. In particular, the turning pipe is a gradual pipe section, which cooperates with the radial pipe that is thin at the bottom and thick at the top for appropriate pressure relief, and can form a longer and higher outlet water column shape without divergence.

[0019] 6. The axial tube is arranged below the flushing water pipeline so that the ratio of the radial tube to the axial tube length is 2:3. The purpose of this design is to ensure the length of the radial tube of the laxative nozzle so that the water flow path in the laxative nozzle tube is long enough to generate sufficient water outlet pressure at the laxative nozzle water outlet.

[0020] 7. The water circuit is heated by an instant heater, and there is no water storage tank in the toilet, which saves electricity and keeps the water clean and hygienic. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to facilitate the understanding of the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1:

[0027] like Figure 1-3 As shown, the present invention discloses a laxative nozzle, including a nozzle tube body 10, in which a flushing water pipeline 20 and a laxative water pipeline are arranged. The laxative water pipeline is sequentially divided into an axial tube 31 arranged along the axial direction of the nozzle, a turning tube 32, and a radial tube 33 arranged along the radial direction of the nozzle.

[0028] The diameter of the radial tube 33 in the defecation water pipeline gradually increases from the water inlet end to the water outlet end. The central axis of the water outlet direction of the bend tube 32 forms an angle with the central axis of the water inlet direction, and the bend tube 32 forms a converged shape with a thick water inlet section and a thin water outlet section. The axial tube 31 is divided into a first tube section 31a and a second tube section 31b, the first tube section 31a is a straight tube section, and the diameter of the second tube section 31b gradually decreases from the water inlet end to the water outlet end.

[0029] Specific pipeline parameters: the aperture of the first pipe section 31a of the axial pipe is 6mm, the aperture of the water inlet hole of the second pipe section 31b is 3mm, and the aperture of the water outlet hole of the second pipe section 31b is 1.6mm; the angle of the turning pipe is 90°, the aperture of the water inlet hole of the turning pipe is 1.6mm, and the aperture of the water outlet hole of the turning pipe is 1.3mm; the aperture of the water inlet hole of the radial pipe is 1.3mm, and the aperture of the water outlet hole of the radial pipe is 1.4mm; the ratio of the length of the radial pipe 33 to the axial pipe 31 is 2:3, the length of the radial pipe 33 is 12mm, and the length of the axial pipe 31 is 18mm.

[0030] From the experimental data, it can be obtained that under the condition of micro-aperture, the structure of thin bottom and thick top is formed, and the height of the water column ejected can reach 20-30 meters without divergence, but can form a better convergent water column shape, which is more convenient for ejection and defecation. The specific internal pipe water pressure of the experiment is as follows:

[0031] Water pressure Height of non-divergence of water jet 0.1Mpa 6cm 0.4Mpa 10cm 0.75Mpa 16cm

[0032] The present invention also provides a toilet equipped with a nozzle of the first embodiment, wherein a water inlet pipeline is connected to a retractable nozzle, a heater for heating the inlet water, a control circuit and a valve for controlling the on and off of the water inlet pipeline are provided in the toilet, and the heater is an instantaneous heater. The flushing water pipeline 20 in the nozzle body 10 forms a straight water inlet pipe section, a first pipe section 31a is formed on the axial pipe 31, and two groups of joint inner pipes with sealing rings are provided on the nozzle, and the two groups of joint inner pipes are respectively plugged with the straight water inlet pipe section and the first pipe section 31a on the axial pipe 31, and the nozzle body 10 is installed on the nozzle.

[0033] The side of the nozzle body 10 in contact with the nozzle is provided with two symmetrical first positioning grooves 40a and second positioning grooves 40b of different widths, and the nozzle shell is provided with two corresponding positioning blocks of different widths, and the two sets of positioning blocks are positioned and connected with the positioning grooves 40 according to the same width. Since the water inlet straight pipe section formed by the flushing water pipeline 20 of the present disclosure has the same aperture as the first pipe section 31a formed on the axial pipe 31, the positioning grooves of different widths cooperate with the positioning blocks of different widths to prevent the flushing water pipeline and the laxative water pipeline from being swapped during the actual installation process, and the different upper and lower widths ensure that the laxative water pipeline in the nozzle is connected to the bottom of the laxative pipe body.

[0034] Embodiment 2:

[0035] Another laxative nozzle disclosed in the present invention has the same structure as the nozzle in the first embodiment, except for the specific pipeline parameters: the aperture of the first pipe section 31a of the axial pipe is 3mm, the aperture of the water inlet of the second pipe section 31b is 4mm, and the aperture of the water outlet of the second pipe section 31b is 1.8mm; the angle of the bend pipe is 90°, the aperture of the water inlet of the bend pipe is 1.8mm, and the aperture of the water outlet of the bend pipe is 1.5mm; the aperture of the water inlet of the radial pipe is 1.5mm, and the aperture of the water outlet of the radial pipe is 1.6mm; the ratio of the length of the radial pipe 33 to the axial pipe 31 is 2:3. The length of the radial pipe 33 is 12mm, and the length of the axial pipe 31 is 18mm.

[0036] Embodiment three:

[0037] like Figure 4 Another disclosure of the present invention is that the radial tube 33 is set as a split tube body, the outer side of the radial tube 33 is provided with an external thread, the nozzle tube body 10 forms a cavity connected to the radial tube 33, and the cavity forms a cylindrical cavity with an internal thread; the radial tube 33 is threadedly connected to the cylindrical cavity of the nozzle tube body 10. The advantage of such a structure is that the radial tube 33 is not installed, and it can be directly used for flushing and buttock washing due to the low water pressure and large aperture of the turning tube. When laxative flushing is required, the radial tube 33 is screwed into the cylindrical cavity of the nozzle tube body 10. For the convenience of installation, the length of the radial tube 33 is greater than the cylindrical cavity of the nozzle tube body 10. After the radial tube is installed, the radial tube protrudes from the nozzle tube body 10, which is also convenient for disassembly. At the same time, a sealing ring is provided at the connection between the radial tube 33 and the nozzle tube body 10. In order to facilitate the removal of the radial tube 33 and have a better flushing effect, a raised annular wall is formed on the bottom of the cylindrical cavity of the nozzle tube body 10 along the circular water outlet.

[0038] In this solution, the water outlet pipe in the radial pipe can be set as 2-3 forked water outlet pipes, that is, the water inlet side of the radial pipe is the main pipe, and the water outlet side forms 2-3 forked water outlet pipes. Due to the large number of pipes, the water pressure is smaller, and the flushing and buttocks washing effects are achieved. The disclosed water pressure is smaller and more convenient for flushing and buttocks washing, the product combination is more flexible, and more diversified rotations can be achieved.

[0039] Embodiment 4:

[0040] The present embodiment discloses that the turning tube 32, the axial tube 31 and the radial tube 33 are provided with continuous double helical spiral grooves. Due to the rotating effect of the double helical threads on the water flow, the water flow is rotated, and the straight water column is changed into a rotating water column, so that the ejected water column has a linear impact force and a rotational impact force, which makes it easier to achieve the effect of ejecting into the rectum.

[0041] The radial tube 33 in this embodiment can be a split structure. Combined with the specific structure in the third embodiment, the advantage of this structure is that the radial tube 33 is not installed, and the water outlet of the turning tube forms a thicker rotating water column with low pressure and large aperture, and the flushing and buttocks washing effect is better. When laxative flushing is needed, the radial tube can be installed.

[0042] The above are only preferred embodiments of the present invention. The protection scope of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
