Description

Technical Field

[0001] The present invention relates to the technical field of intelligent sanitary wares, and particularly relates to an intelligent toilet, an intelligent toilet seat, as well as a spray gun and a nozzle thereof. Background Art

[0002] In the existing intelligent toilet, there are three nozzles of buttock washing, feminine washing, and defecation cleaning on its spray gun. Different nozzles spray cleaning water with different water patterns, and the three nozzles are respectively communicated with the water inlet through different flow channels. The spray gun rotates a reversing valve through a motor to switch the spray washing water among the three nozzles, so as to realize the switching of different cleaning water patterns. During the cleaning operation, if it is necessary to switch the cleaning mode, the spray gun needs to first stop the current function, then retract the spray gun. After the reversing valve piece is switched to the required function and the residual cold water in the new mode pipeline is drained out, the spray gun extends out again and sprays the human body again. Thus, it takes 15 - 20 seconds to switch the mode, resulting in a poor user experience. Summary of the Invention

[0039] In existing intelligent toilets, there are three nozzles, namely buttock washing nozzle, feminine washing nozzle, and defecation nozzle, on the spray gun. Different nozzles spray cleaning water with different water patterns, and the three nozzles are respectively connected to the water inlet through different flow channels. The spray gun rotates the reversing valve through a motor to switch the spray washing water among the three nozzles, thereby realizing the switching of different cleaning water patterns. During the cleaning operation, if it is necessary to switch the cleaning mode, the spray gun needs to first stop the current function, then retract the spray gun. After the reversing valve plate is switched to the required function and the residual cold water in the new mode pipeline is drained, the spray gun extends again and sprays the human body again. In this way, it takes 15 - 20 seconds to switch the mode, resulting in a poor user experience.

Among them, the mounting bracket 102b is fixedly installed inside the cover body 102a. For example, the mounting bracket 102b is fixed inside the cover body 102a by means of screws through threaded connection. The spray gun 102c is slidably assembled on the mounting bracket 102b.

[0044] Figure 3 It is a partial perspective view of the intelligent toilet seat cover provided by an embodiment of the present application.

[0045] Refer to Figure 3 As shown, the above-mentioned spray gun 102c includes an outer sleeve 1020 and a nozzle 1021. Among them, the nozzle 1021 is coaxially and fixedly connected to the front end of the outer sleeve 1020.

[0046] The nozzle 1021 includes a housing 1, a sliding member 3, and a transmission member. Among them, a channel 1c communicating with the water inlet part 11, a slideway 1d communicating with the channel 1c and extending axially, and a spray hole 12 communicating with the slideway 1d are provided inside the housing 1. The top surface of the slideway 1d slopes downward toward the front end of the housing 1. One end of the spray hole 12 is a water inlet 123, and the other end is a water outlet 124. The water inlet 123 is located on the top surface of the slideway 1d, and the water outlet 124 is located on the upper side of the housing 1. At least two eddy current grooves 190 communicating with the water inlet 123 and arranged at intervals around the water inlet 123 are recessed on the top surface of the slideway 1d.

[0047] The upper side surface of the sliding member 3 is an inclined surface that fits the top surface of the slideway 1d. The sliding member 3 is slidably installed in the slideway 1d, and the upper side surface of the sliding member 3 is in sliding guide cooperation with the top surface of the slideway 1d.

[0048] The transmission member is in transmission connection with the sliding member 3 to drive the sliding member 3 to slide along the slideway 1d, so that the spray hole 12 ejects spray washing water of different water types.

[0049] The transmission member in the nozzle 1021 is in transmission connection with the sliding member 3 to drive the sliding member 3 to slide along the slideway 1d, so that the spray hole 12 ejects spray washing water of different water types. During the process of realizing the switching of the spray washing mode, there will be no water interruption, improving the user experience effect.

[0050] Figure 4 It is a perspective view of the nozzle provided by an embodiment of the present application. Figure 5 It is a bottom view of the second shell part provided by an embodiment of the present application. Figure 6 It is a cross-sectional view of the nozzle provided by an embodiment of the present application.

[0051] Refer to Figures 4 to 6As shown in the figure, the nozzle 1021 includes a housing 1, a rotating shaft 2, and a sliding member 3. Among them, the housing 1 is generally cylindrical, and a water inlet portion 11 is provided at its rear end. The water inlet portion 11 can be a water inlet hole opened at the end of the housing 1 near the edge. In this embodiment, the water inlet portion 11 can also be a water inlet pipe provided at the end of the housing 1, as shown in Figure 4 shown.

[0052] Inside the housing 1, there is a channel 1c communicating with the water inlet portion 11, a slideway 1d communicating with the channel 1c and extending axially, and a spray hole 12 communicating with the slideway 1d. Among them, the top surface of the slideway 1d slopes downward toward the front end of the housing 1. The lower position of the top surface of the slideway 1d is located at the edge of the closed end of the slideway 1d.

[0053] Inside the housing 1, there are a channel 1c, a slideway 1d, and a spray hole 12. Among them, the channel 1c communicates with the water inlet portion 11. The slideway 1d extends along the axial direction of the housing 1, and the slideway 1d communicates with the channel 1c. The spray hole 12 communicates with the slideway 1d.

[0054] The top surface of the slideway 1d slopes downward toward the front end of the housing 1. The lower position of the top surface of the slideway 1d is located at the edge of the closed end of the slideway 1d.

[0055] One end of the spray hole 12 is a water inlet 123, and the other end is a water outlet 124. The water inlet 123 is located on the top surface of the slideway 1d, and the water outlet 124 is located on the upper side of the housing 1. At least two eddy current grooves 190 that communicate with the water inlet 123 and are arranged at intervals around the water inlet 123 are recessed on the top surface of the slideway 1d.

[0056] The upper side surface of the sliding member 3 is an inclined surface that fits the top surface of the slideway 1d. The sliding member 3 can be slidably installed in the slideway 1d, and the upper side surface of the sliding member 3 is in sliding guide cooperation with the top surface of the slideway 1d.

[0057] The rotating shaft 2 is used as a transmission member, and it can rotatably pass through the housing 1. One end of the rotating shaft 2 is in threaded cooperation with the sliding member 3. As the rotating shaft 2 rotates, it can drive the sliding member 3 to slide along the slideway 1d, so that the spray hole 12 ejects washing water of different water types, and there will be no interruption of water flow during the process of realizing the switching of the washing mode, improving the user experience effect.

[0058] The housing 1 is assembled by a first housing portion 1e and a second housing portion 1f. The water inlet portion 11 is provided at the rear end of the first housing portion 1e, the channel 1c is opened on the upper side of the first housing portion 1e, the spray hole 12 is opened on the upper side of the second housing portion 1f, and the slideway 1d is opened on the lower side of the second housing portion 1f.

[0059] After the first shell portion 1e and the second shell portion 1f are assembled into the housing 1 by snap-fitting, both ends are aligned, the upper side of the first shell portion 1e is abutted against the lower side of the second shell portion 1f, the channel 1c is connected to the slideway 1d, and the rotating shaft 2 can be rotatably penetrated in the second shell portion 1f.

[0060] Of course, in addition to being split into the upper and lower first shell portion 1e and the second shell portion 1f for ease of manufacturing and assembly, the shell 1 can also be split into two symmetrical parts for manufacturing and assembly.

[0061] One end of the rotating shaft 2 is provided with an external thread, and the sliding member 3 is provided with an internal thread that matches the external thread, so that the spiral transmission between the rotating shaft 2 and the sliding member 3 can be realized. The other end of the rotating shaft 2 can pass through the housing 1 and be connected to the driving device, and the driving device drives the rotating shaft 2 to rotate.

[0062] It can be understood that one end of the rotating shaft 2 is provided with an internal thread, and a threaded column that matches the internal thread is fixedly connected to the sliding member 3, so as to realize the spiral transmission of the rotating shaft 2 and the sliding member 3. The other end of the rotating shaft 2 can pass through the housing 1 and be connected to the driving device, and the driving device drives the rotating shaft 2 to rotate.

[0063] The sliding member 3 can slide along the slideway 1d as the rotating shaft 2 rotates, so that the spray hole 12 can spray different types of spray water for washing the human body. In the process of switching the spray mode, no interruption will occur, which improves the user experience.

[0064] When the rotating shaft 2 drives the sliding member 3 to move to the first position, the water outlet 124 emits a large cone-angle water jet pattern; when the rotating shaft 2 drives the sliding member 3 to move to the second position, the water outlet 124 emits a small cone-angle water jet pattern; when the rotating shaft 2 drives the sliding member 3 to move to the third position, the water outlet 124 emits a thin cylindrical water jet pattern.

[0065] The water jet pattern changes gradually from a large cone angle water jet pattern to a small cone angle water jet pattern, and then changes gradually from a small cone angle water jet pattern to a thin cylindrical water jet pattern without interruption of flow, thus achieving a gradual change of the water jet pattern, making the water jet pattern a gradual water pattern.

[0066] See also Figure 5 As shown, the vortex groove 190 is in a strip shape, and two vortex grooves 190 are connected to the water inlet 123 and are symmetrically reversed around the water inlet 123. Each vortex groove 190 is tangent to the water inlet 123, and each vortex groove 190 is arranged at a certain inclination along the circumference of the water inlet 123.

[0067] The arrangement of the eddy current groove 190 helps to form a spirally rising water column in the injection hole 12, thereby changing the rotation speed of the warm cleaning water in the injection hole 12. The faster the rotation speed of the warm cleaning water, the larger the injection angle of the ejected cleaning water.

[0068] Refer to Figure 6 As shown, the injection hole 12 is inclined towards the front end of the housing 1. For example, the axis of the injection hole 12 is perpendicular to the top surface of the slideway 1d. The angle formed by the central axis of the injection hole 12 and the central axis of the housing 1 towards the rear end of the housing is between 100 degrees and 150 degrees. The axis of the injection hole 12 and the axis of the housing 1 form a non-90-degree angle. The larger the inclination angle of the injection hole 12 towards the front end of the housing 1, the more conducive it is to increasing the injection distance of the cleaning water ejected from the injection hole 12.

[0069] It can be understood that the injection hole 12 can be a hole with a variable aperture, which is axially divided into multiple hole parts, and the apertures between different hole parts are not equal.

[0070] Refer to again Figure 6 As shown, the injection hole 12 includes a first hole part 120, a second hole part 121, and a third hole part 122 that are connected in sequence. The opening of the first hole part 120 passing through the housing 1 is the water inlet 123, the second hole part 121 converges towards the third hole part 122, and the opening of the third hole part 122 passing through the housing 1 is the water outlet 124. The third hole part 122 is a vertical hole. It can be understood that when the length of the third hole part 122 is long enough, the third hole part 122 can also converge towards the water outlet 124.

[0071] Among them, the first hole part 120 is cylindrical, the second hole part 121 is frustum-shaped, and the third hole part 122 is cylindrical or conical.

[0072] Figure 7 It is the first water type injection diagram of the nozzle provided by the embodiment of the present application.

[0073] When the rotating shaft 2 drives the sliding member 3 to move to the first position, the first water type is ejected from the water outlet 124, as Figure 7 shown. The first water type is annular. This water type has the largest cleaning area and is the softest, suitable for the feminine wash function.

[0074] Figure 8 It is the second water type injection diagram of the nozzle provided by the embodiment of the present application.

[0075] When the rotating shaft 2 drives the sliding member 3 to move to the second position, the second water type is ejected from the water outlet 124, as Figure 8 shown. The second water type is a thick cylinder. This water type is suitable for the buttock wash function.

[0076] Figure 9 It is the third water type injection diagram of the nozzle provided by the embodiment of the present application.

[0077] When the rotating shaft 2 drives the sliding member 3 to move to the third position, the water outlet 124 ejects the third water pattern, as Figure 9 shown. The third water pattern is a thin cylindrical shape, and this kind of water pattern is suitable for the defecation function.

[0078] In summary, during the process of the nozzle 1021 realizing the switching of the washing modes, there will be no water interruption, improving the user experience effect.

[0079] In addition, in addition to using the above-mentioned rotating shaft 2 as the transmission member, a telescopic shaft with the functions of extending and retracting can also be used. The telescopic shaft is arranged in the housing 1, and one end of the telescopic shaft is fixedly connected or hinged to the sliding member 3. The telescopic movement of the telescopic shaft can drive the sliding member 3 to slide along the slideway 1d.

[0080] When the telescopic shaft drives the sliding member 3 to move to the first position, the water outlet 124 ejects a large cone angle spray water pattern; when the telescopic shaft drives the sliding member 3 to move to the second position, the water outlet 124 ejects a small cone angle spray water pattern; when the telescopic shaft drives the sliding member 3 to move to the third position, the water outlet 124 ejects a thin cylindrical spray water pattern from the water outlet 124.

[0081] The spray water pattern gradually changes from the large cone angle spray water pattern to the small cone angle spray water pattern, and then from the small cone angle spray water pattern to the thin cylindrical spray water pattern, without water interruption, realizing the gradual change of the spray water pattern, making the spray water pattern a gradually changing water pattern.

[0082] When the telescopic shaft drives the sliding member 3 to move to the first position, the water outlet 124 ejects the first water pattern, as shown in Figure 7. The first water pattern is annular, and this kind of water pattern has the largest cleaning area and is the softest, suitable for the feminine wash function.

[0083] When the telescopic shaft drives the sliding member 3 to move to the second position, the water outlet 124 ejects the second water pattern, as shown in Figure 8. The second water pattern is a thick cylindrical shape, and this kind of water pattern is suitable for the buttocks wash function.

[0084] When the telescopic shaft drives the sliding member 3 to move to the third position, the water outlet 124 ejects the third water pattern, as shown in Figure 9. The third water pattern is a thin cylindrical shape, and this kind of water pattern is suitable for the defecation function.

[0085] During the process of the nozzle 1021 realizing the switching of the washing modes, there will be no water interruption, improving the user experience effect.

[0086] While the invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but rather should be broadly construed within the spirit and scope defined by the appended claims, and thus all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
